Nolan is going to a carnival that has games and rides. Each game costs $2.50
and each ride costs $3.50. Nolan spent $52.50 altogether on 17 games and
rides. Write a system of equations that could be used to determine the
number of games Nolan played and the number of rides Nolan went on.
Define the variables that you use to write the system.

Answers

Hence, the equation is of the form \(2.5x+3.5y=52.50\).

What is the system of equation?

A system of equations, also known as a set of simultaneous or an equation system, is a finite set of equations for which we sought the common solutions.

Here given that,

Nolan is going to a carnival that has games and rides. Each game costs $\(2.50\) and each ride costs $\(3.50\). Nolan spent $\(52.50\) altogether on \(17\) games and rides.

So, let us assume that the number of games are \(x\) and the number of rides are \(y\).

So, the equation is of the form

\(2.5x+3.5y=52.50 ........(1)\)

And Noaln spent altogether $\(52.50\) on \(17\) games and rides.

So,

\(x+y=17\)

Then,

\(2.5x+2.5y=2.5(x+y)\\As,\\x+y=17\\So,\\=2.5(17)\\\\=42.5.....(2)\)

Now, subtract equation \((2)\) from equation \((1)\), we get

\(x=52.5-42.5\\\\x=10\)

\(y=17-10\\y=7\)

So the equation is of the form

\(2.5(7)+3.5(10)=52.50\\17.5+35=52.50\\52.50=52.50\)

Hence, the equation is of the form \(2.5x+3.5y=52.50\).

Question 1
The double box-and-whisker plot shows the goals scored per game by two hockey teams during a 20-game season.

Answers

Based on the information in the graph, it can be inferred that team B scores 4 more goals per game.

How do you compare populations using measures of center and median?

To compare the populations using measures of center and median we must carry out the following procedure:

Team A

Median = 3

Q₁ = 2

Q₃ = 4

IQR = Q₃ - Q₁ = 4 - 2 = 2

Team B

Median = 7

Q₁ = 6

Q₃ = 8

IQR = Q₃ - Q₁ = 8 - 6 = 2

According to the information above, the variation in goals scored is the same. However, team B usually scores 4 more goals than team A for each game.

Additionally, the difference in the mean of these two values is 2.

A long, straight wire lies along the y-axis and carries current in the positive y-direction. A positive point charge moves along the x-axis in the positive x-direction. The magnetic force that the wire exerts on the point charge is in

Answers

The magnetic force that the wire exerts on the point charge is in the negative z-direction.

When a current-carrying wire and a moving point charge are placed in a magnetic field, a magnetic force is exerted on the moving charge due to the interaction between the magnetic field and the charge's velocity. According to the right-hand rule, the direction of the magnetic force is perpendicular to both the velocity of the moving charge and the magnetic field created by the current-carrying wire.

In this scenario, the wire carrying current in the positive y-direction generates a magnetic field that circulates around the wire. The point charge moving along the x-axis in the positive x-direction experiences a magnetic force directed perpendicularly to both the velocity (positive x-direction) and the magnetic field (circulating around the wire). Applying the right-hand rule, the magnetic force is found to be in the negative z-direction, which is downward and perpendicular to the x and y axes.

Based on the t-test assuming equal variances a. Examining the ratio of the variances, it is reasonable to conclude that the variances are unequal."

It is vital to establish whether or not the variances of the two groups being compared are indeed identical before performing a t-test under the assumption of equal variances. This is significant since the t-calculation statistic depends on the assumption that variances are equal.

One can look at the ratio of the variances between the two groups to evaluate the assumption of equal variances. Typically, it is acceptable to infer that the variances are not equal if the ratio of the variances is more than two or lower than half. One can presume that the variances are equal in the absence of such proof. Since the variances are not equal, it is not logical to infer that they are.

Answers

The ages of the crew, Marty and Blakeley are 32 years, 48 years and 24 years respectively.

Algebra

Crew's age = xMarty's age = 1.5xBlakely's age = 0.75x

Total ages = 104

Total = crew's age + Marty's age + blakely's age

104 = x + 1.5x + 0.75x

104 = 3.25x

x = 104 ÷ 3.25

x = 32 years

Therefore,

Crew's age = x

Assume that the height, X, of a college woman is a normally distributed random variable with a mean of 65 inches and a standard deviation of 3 inches. Suppose that we sample the heights of 180 randomly chosen college women. Let M be the sample mean of the 180 height measurements. Let S be the sum of the 180 height measurements. All measurements are in inches. a) What is the probability that X < 59? b) What is the probability that X > 59? c) What is the probability that all of the 180 measurements are greater than 59? d) What is the expected value of S? e) What is the standard deviation of S? f) What is the probability that S-180*65 >10? g) What is the standard deviation of S-180*65 h) What is the expected value of M? i) What is the standard deviation of M? j) What is the probability that M >65.41? k) What is the standard deviation of 180*M? l) If the probability of X > k is equal to .3, then what is k?

Answers

a) The probability that X < 59 is approximately 0.0013.

b) The probability that X > 59 is approximately 0.9987.

c) The probability that all of the 180 measurements are greater than 59 is approximately 0.9987^180.

d) The expected value of S is 180 * 65 = 11700 inches.

e) The standard deviation of S is 180 * 3 = 540 inches.

f) The probability that S - 180 * 65 > 10 is approximately 0.9997.

g) The standard deviation of S - 180 * 65 is 540 inches.

h) The expected value of M is 65 inches.

i) The standard deviation of M is 3 / √180 inches.

j) The probability that M > 65.41 is approximately 0.3476.

k) The standard deviation of 180 * M is 3 inches.

l) If the probability of X > k is equal to 0.3, then k is approximately 67.39 inches.

To find the probability that X < 59, we need to calculate the z-score first. The z-score formula is (X - μ) / σ, where X is the value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get a z-score of (59 - 65) / 3 = -2. Therefore, using the z-table or a calculator, we find that the probability is approximately 0.0013.

Similarly, to find the probability that X > 59, we can use the z-score formula. The z-score is (59 - 65) / 3 = -2. The probability of X being greater than 59 is equal to 1 minus the probability of X being less than or equal to 59. Using the z-table or a calculator, we find that the probability is approximately 0.9987.

The probability that all of the 180 measurements are greater than 59 is the probability of one measurement being greater than 59 raised to the power of 180. Since the probability of a single measurement being greater than 59 is approximately 0.9987, the probability of all 180 measurements being greater than 59 is approximately \(0.9987^1^8^0\).

The expected value of S is the sum of the expected values of the individual measurements. Since the mean height is 65 inches, the expected value of each measurement is 65. Since we have 180 measurements, the expected value of S is 180 * 65 = 11700 inches.

The standard deviation of S is the square root of the sum of the variances of the individual measurements. Since the standard deviation of each measurement is 3 inches, the variance is 3² = 9. Since we have 180 measurements, the variance of S is 180 * 9 = 1620 inches². Taking the square root, we get the standard deviation of S as √1620 = 540 inches.

To find the probability that S - 180 * 65 > 10, we need to calculate the z-score for the difference. The z-score formula is (X - μ) / σ, where X is the value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get a z-score of (10 - 0) / 540 = 0.0185. Using the z-table or a calculator, we find that the probability is approximately 0.9997.

The standard deviation of S - 180 * 65 is the same as the standard deviation of S, which is 540 inches.

The expected value of M, the sample mean, is equal to the population mean, which is 65 inches.

The standard deviation of M, denoted as σ_M, is given by σ / √n, where σ is the standard deviation of the population and n is the sample size. Plugging in the values, we get σ_M = 3 / √180 inches.

To find the probability that M > 65.41, we need to calculate the z-score for M. The z-score formula is (X - μ) / (σ / √n), where X is the value, μ is the mean, σ is the standard deviation of the population, and n is the sample size. Plugging in the values, we get a z-score of (65.41 - 65) / (3 / √180) ≈ 0.733. Using the z-table or a calculator, we find that the probability is approximately 0.3476.

The standard deviation of 180 * M is equal to the standard deviation of M divided by the square root of 180. Since the standard deviation of M is 3 / √180 inches, the standard deviation of 180 * M is 3 inches.

If the probability of X > k is equal to 0.3, we need to find the corresponding z-score from the z-table or using a calculator. The z-score represents the number of standard deviations away from the mean. From the z-score, we can calculate the value of k by rearranging the z-score formula: z = (k - μ) / σ. Solving for k, we get k = z * σ + μ. Plugging in the values, we get k = 0.5244 * 3 + 65 ≈ 67.39 inches.

Answers

The slope of the line which passes through the points (4, 18) and (6x, 2k) is (k - 9)/(3x - 2).

According to the given question.

A line passes through points (4, 18) and (6x,2k).

Which means we have two points (4, 18) and (6x,2k).

As we know that, the slope of a line is the ratio of the amount that y increases as x increases some amount.And the slope formula is m=(y2-y1)/(x2-x1) if a lines passes through the point (x2, y2) and (x1, y1).

Therefore, the slope of the line which passes through the points (4, 18) and (6x,2k)

= 2k - 18/ 6x - 4

= 2[k - 9]/2[3x - 2]

= (k-9)/(3x - 2)

Hence, the slope of the line which passes through the points (4, 18) and (6x, 2k) is (k - 9)/(3x - 2).

A shipment of 14 television sets includes three that are defective. In how many wats can a hotel purchase four of these sets and receive at least two of the defective sets?

Answers

The hotel can purchase four television sets from the shipment in 36 different ways and can receive at least two defective sets.the hotel can purchase four television sets from the shipment in 177 different ways and receive at least two of the defective sets.

Step 1: Calculate the number of ways to choose 4 television sets from the shipment of 14. This can be done using the combination formula: C(n, k) = n! / (k! * (n-k)!), where n is the total number of items and k is the number of items to be chosen. In this case, n = 14 and k = 4.

C(14, 4) = 14! / (4! * (14-4)!) = 14! / (4! * 10!) = (14 * 13 * 12 * 11) / (4 * 3 * 2 * 1) = 1001.

Step 2: Calculate the number of ways to choose at least 2 defective sets from the 3 defective sets available. This can be done by considering the possible combinations: choosing 2 defective and 2 non-defective, choosing 3 defective and 1 non-defective, or choosing all 3 defective sets.

Number of ways to choose 2 defective and 2 non-defective: C(3, 2) * C(11, 2) = 3 * 55 = 165.

Number of ways to choose 3 defective and 1 non-defective: C(3, 3) * C(11, 1) = 1 * 11 = 11.

Number of ways to choose all 3 defective sets: C(3, 3) * C(11, 0) = 1 * 1 = 1.

Step 3: Add up the results from Step 2 to get the total number of ways to choose at least 2 defective sets: 165 + 11 + 1 = 177.

Therefore, the hotel can purchase four television sets from the shipment in 177 different ways and receive at least two of the defective sets.

Answers

Answer:

1. (5·sin(A) - 3·cos(A)/(4·cos(A) + 5·sin(A))  = 1/8

2. θ = 30°

3. tan(θ) - cot(θ) = (2·sin²(θ) -1)/((cos(θ)×sin(θ))

from tan(θ) - 1/tan(θ) = sin(θ)/cos(θ) - cos(θ)/sin(θ) and sin²(θ) +  cos²(θ) = 1

4. tan10°·tan15°·tan75°·tan80°= 1 from;

sin(α)·sin(β) = 1/2[cos(α - β) - cos(α + β)]

cos(α)·cos(β) = 1/2[cos(α - β) + cos(α + β)]

5. x² + y² = a² + b² where x = a·cosθ - b·sinθ and y = a·sinθ + b·cosθ from;

cos²θ + sin²θ = 1

Step-by-step explanation:

1. Here we have 5·tan(A) = 5·sin(A)/cos(A) = 4

∴ 5·sin(A) = 4·cos(A)

Hence to find the value of (5·sin(A) - 3·cos(A)/(4·cos(A) + 5·sin(A)) we have;

Substituting the value for 5·sin(A) = 4·cos(A) into the above equation in both the numerator and denominator we have;

(4·cos(A) - 3·cos(A)/(4·cos(A) + 4·cos(A)) = cos(A)/(8·cos(A)) = 1/8

Therefore, (5·sin(A) - 3·cos(A)/(4·cos(A) + 5·sin(A)) = 1/8

2. For the equation as follows, we have

\(\frac{sin \theta}{1 + cos \theta} + \frac{1 + cos \theta}{sin \theta} = 4\) this gives

\(\frac{2sin (\theta/2) cos (\theta/2) }{2 cos^2 (\theta/2)} + \frac{2 cos^2 (\theta/2)}{2sin (\theta/2) cos (\theta/2) } = 4\)

\(tan\frac{\theta}{2} + \frac{1}{tan\frac{\theta}{2} } = 4\)

\(tan^2\frac{\theta}{2} + 1 = 4\times tan\frac{\theta}{2}\)

\(tan^2\frac{\theta}{2} - 4\cdot tan\frac{\theta}{2} + 1 = 0\)

We place;

\(tan\frac{\theta}{2} = x\)

∴ x² - 4·x + 1 = 0

Factorizing we have

(x - (2 - √3))·(x - (2 + √3))

Therefore, tan(θ/2) = (2 - √3) or (2 + √3)

Solving, we have;

θ/2 = tan⁻¹(2 - √3) or tan⁻¹(2 + √3)

Which gives, θ/2 = 15° or 75°

Hence, θ = 30° or 150°

Since 0° < θ < 90°, therefore, θ = 30°

3. We have tan(θ) - cot(θ) = tan(θ) - 1/tan(θ)

Hence, tan(θ) - 1/tan(θ) = sin(θ)/cos(θ) - cos(θ)/sin(θ)

∴  tan(θ) - 1/tan(θ) = (sin²(θ) -  cos²(θ))/(cos(θ)×sin(θ))...........(1)

From sin²(θ) +  cos²(θ) = 1, we have;

cos²(θ) = 1 - sin²(θ), substituting the value of sin²(θ) in the equation (1) above, we have;

(sin²(θ) -  (1 - sin²(θ)))/(cos(θ)×sin(θ)) = (2·sin²(θ) -1)/((cos(θ)×sin(θ))

Therefore;

tan(θ) - cot(θ) = (2·sin²(θ) -1)/((cos(θ)×sin(θ))

4. tan10°·tan15°·tan75°·tan80°= 1

Here we have since;

sin(α)·sin(β) = 1/2[cos(α - β) - cos(α + β)]

cos(α)·cos(β) = 1/2[cos(α - β) + cos(α + β)]

Then;

tan 10°·tan15°·tan75°·tan80° = tan 10°·tan80°·tan15°·tan75°

tan 10°·tan80°·tan15°·tan75° = \(\frac{sin(10^{\circ})}{cos(10^{\circ})} \times \frac{sin(80^{\circ})}{cos(80^{\circ})} \times \frac{sin(15^{\circ})}{cos(15^{\circ})} \times \frac{sin(75^{\circ})}{cos(75^{\circ})}\)

Which gives;

\(\frac{sin(10^{\circ}) \cdot sin(80^{\circ})}{cos(10^{\circ})\cdot cos(80^{\circ})} \times \frac{sin(15^{\circ}) \cdot sin(75^{\circ})}{cos(15^{\circ})\cdot cos(75^{\circ})}\)

\(=\frac{1/2[cos(80 - 10) - cos(80 + 10)]}{1/2[cos(80 - 10) + cos(80 + 10)]} \times \frac{1/2[cos(75 - 15) - cos(75 + 15)]}{1/2[cos(75 - 15) + cos(75 + 15)]}\)

\(=\frac{1/2[cos(70) - cos(90)]}{1/2[cos(70) + cos(90)]} \times \frac{1/2[cos(60) - cos(90)]}{1/2[cos(60) + cos(90)]}\)

\(=\frac{[cos(70)]}{[cos(70) ]} \times \frac{[cos(60)]}{[cos(60) ]} =1\)

5. If x = a·cosθ - b·sinθ and y = a·sinθ + b·cosθ

∴ x² + y² = (a·cosθ - b·sinθ)² + (a·sinθ + b·cosθ)²

= a²·cos²θ - 2·a·cosθ·b·sinθ +b²·sin²θ + a²·sin²θ + 2·a·sinθ·b·cosθ + b²·cos²θ

= a²·cos²θ + b²·sin²θ + a²·sin²θ + b²·cos²θ

= a²·cos²θ + b²·cos²θ + b²·sin²θ + a²·sin²θ

= (a² + b²)·cos²θ + (a² + b²)·sin²θ

= (a² + b²)·(cos²θ + sin²θ) since cos²θ + sin²θ = 1, we have

= (a² + b²)×1 = a² + b²

i choose a random integer n between $1 and $10 inclusive what is the probability that for the n i chose there exist no real solutions to the equation x x 5 n express your answer as a common fraction

Answers

The probability that for a randomly chosen integer n between 1 and 10 inclusive there exist no real solutions to the equation x^2 + 5 = n is 3/10.

we can first find the values of n for which there are real solutions to the equation x^2 + 5 = n. We can do this by rearranging the equation to get x^2 = n - 5 and then seeing that there are real solutions only if n - 5 is non-negative, i.e. n >= 5.

Since we are choosing a random integer between 1 and 10 inclusive, there are 10 possible values for n. Out of these, only 5, 6, 7, 8, 9, and 10 are greater than or equal to 5, which means that there are real solutions to the equation for these values of n. Therefore, there are only 6 possible values of n for which there exist no real solutions to the equation.

Therefore, the probability of choosing one of these 6 values of n is 6/10, which simplifies to 3/5. However, we need to find the probability of choosing one of the values of n for which there exist no real solutions to the equation, which is the complement of the probability of choosing one of the values of n for which there are real solutions. This complement is 1 - 6/10, which simplifies to 2/5.

Therefore, the main answer to the question is that the probability that for a randomly chosen integer n between 1 and 10 inclusive there exist no real solutions to the equation x^2 + 5 = n is 2/5.

The probability that for a randomly chosen integer n between 1 and 10 inclusive there exist no real solutions to the equation x^2 + 5 = n is 2/5. This can be found by first determining the values of n for which there are real solutions to the equation, and then finding the complement of this probability.

Answers

The length of the straw is √101 inches

How to find the length of the straw?

The rectangular box has:

length (l) = 6 inches

breadth (b) = 4 inches

height (h) = 7 inches

The straw is said to fit into the box diagonally from the bottom.

So, the length of the straw is calculated as:

S= √(l² + b² + h²)

S = √(6² + 4² + 7²)

S = √101 inches

Answers

K'(-2, 1) is the coordinate of the image of point K, found by multiplying the original x-coordinate of the point K (2) by -1. To reflect the triangle over the y-axis, the x-coordinate of each point is multiplied by -1.

What is triangle?

Triangle is a three-sided geometric shape which has three angles and three sides. The three sides of a triangle are typically referred to as the base, the height, and the hypotenuse. A triangle can be classified as either right, obtuse, or acute depending on the measure of its angles. Right triangles have one right angle, obtuse triangles have one obtuse angle, and acute triangles have three acute angles.

The coordinate of the image of point K is K’(-2, 1). This means that the x-coordinate of the point is -2 and the y-coordinate of the point is 1. This can be found by multiplying the original x-coordinate of the point K (2) by -1. The y-coordinate of point K remains the same, so the y-coordinate of the image of point K is 1.

Therefore, the coordinate of the image of point K is K’(-2, 1).
