Answer: 1 over 20

Step-by-step explanation: If the spinner has 5 parts to it at purple is one of those parts then the spinner has a 1/5 chance of it landing there.

If there are 4 cards and 1 of them are pink then there is a 1/4 chance of picking pink(if done randomly)

So if we mutiply 1/4 and 1/5, we get 1/20

That is how I arrived at my answer of 1 over 20

Answer:

a) Speed of the cyclist is (2.75/0.4) = 6.875 miles per hour.

b) It will take (5.5/6.875) = 0.8 hours to travel 5.5 miles at this rate.

To find the maximum height the ball achieves before landing, we need to find the vertex of the parabola represented by the equation h(t) = -16t^2 + 59.2t + 114.24. The vertex form of a parabola's equation is y = a(x-h)² + k where (h, k) is the coordinates of the vertex.

We can get the vertex form by completing the square of x term.

h(t) = -16t² + 59.2t + 114.24

h(t) = -16(t² - 3.68t) + 114.24 + 3.68t

h(t) = -16(t-0.92)² + 118.92

The maximum height is 118.92 ft which is k.

The probability that 3 of the next 5 days have two accidents is approximately  0.225. We can use the Poisson distribution to model the number of traffic accidents on each day, with a mean of 2. Let X be the number of accidents on a single day, then X ~ Poisson(2).

(a) To find the probability that 3 of the next 5 days have two accidents, we can use the binomial distribution since we are interested in the number of successes (days with two accidents) in a fixed number of trials (5 days). Let Y be the number of days with two accidents in 5 days, then Y ~ Binomial(5, P), where P is the probability of having two accidents on a single day.

Since X ~ Poisson(2), we know that P(X = 2) = e^(-2) * 2^2 / 2! = 0.2707 (using the Poisson probability formula). Therefore, P = 0.2707 is the probability of having two accidents on a single day.

Using the binomial probability formula, we can find the probability of having exactly 3 days with two accidents in 5 days:

P(Y = 3) = (5 choose 3) * 0.2707^3 * (1 - 0.2707)^2 = 0.225

Therefore, the probability that 3 of the next 5 days have two accidents is approximately 0.225.

The minimum score needed to be in the top 2% of the exam is 90.5, which is two standard deviations above the mean.

To calculate the minimum score needed to be in the top 2%, we need to find the value of two standard deviations above the mean. This can be done using the formula x = μ + (2σ), where μ represents the mean and σ represents the standard deviation. In this case, μ = 76.4 and σ = 6.1. We substitute these values into the formula to get x = 76.4 + (2*6.1), which equals 90.5. Therefore, the minimum score needed to be in the top 2% is 90.5. To further understand this calculation, it is important to note that the normal distribution curve is symmetrical. This means that the area under the curve that is two standard deviations above the mean is 2%, which is the same as the area under the curve that is two standard deviations below the mean. Therefore, the score that is two standard deviations above the mean is the minimum score needed to be in the top 2%.

The coefficient of x^4 in the expression 4x³ - 5x² + 2x² + 3 is 0. The coefficient of x is 0 as well.

To determine the coefficient of a specific term in a polynomial expression, we need to identify the term and examine its coefficient. In the given expression, 4x³ - 5x² + 2x² + 3, there is no term with x^4. Therefore, the coefficient of x^4 is 0.

Additionally, since there is no standalone term of x, the coefficient of x is also 0.

To find the zeroes of the function f(z) = z² - 2z, we need to set the function equal to 0 and solve for z:

z² - 2z = 0

We can factor out z from the equation:

z(z - 2) = 0

Now we have two possibilities:

1. z = 0

2. z - 2 = 0, which gives z = 2

Therefore, the zeroes of f(z) = z² - 2z are z = 0 and z = 2.

To find the product of (4 + 5x)(4 - 5x), we can use the FOIL method, which stands for First, Outer, Inner, Last:

(4 + 5x)(4 - 5x) = 4 * 4 + 4 * (-5x) + 5x * 4 + 5x * (-5x)

Simplifying the expression, we get:

16 - 20x + 20x - 25x^2

Combining like terms, we have:

16 - 25x^2

Therefore, the product of (4 + 5x)(4 - 5x) is 16 - 25x^2.

The value of k in the polynomial x³ + kx is 0.

To determine the value of k, we need to set the polynomial equal to 0 and solve for k:

x³ + kx = 0

We can factor out x from the equation:

x(x² + k) = 0

Now, there are two possibilities:

1. x = 0

2. x² + k = 0

If x = 0, then the polynomial is already equal to 0, regardless of the value of k.

To find the value of k when x² + k = 0, we can solve for k:

k = -x²

The differential equation for the time evolution of the toxic chemical in the pond is dy/dt = -200y + (100/2000)x

where y represents the amount (in kg) of the contaminant in the pond and x represents the amount of contaminant added to the pond per minute (5 kg/minute in this case). The negative sign in the equation indicates that the amount of contaminant is decreasing in the pond, while the positive term (100/2000)x indicates that the contaminant is being added to the pond at the rate of 5 kg/minute.

To solve for y, we can integrate the equation with respect to time. We start by multiplying both sides by dt, giving us the integral form of the equation: dy = -200y dt + (100/2000)x dt. Integrating both sides gives us the solution y = -200y(t) + (100/2000)x(t) + C, where C is an integration constant. Since we know the initial amount of contaminant in the pond is 5 kg, we can set y(0) = 5 and solve for C, giving us C = 5. Therefore, the solution to the differential equation is y(t) = -200y(t) + (100/2000)x(t) + 5.

Answer:

The slope is 3/8

Step-by-step explanation:

The slope of the line given by the equation 3x - 8y = -16 is 3/8.

To find the slope of the line given by the equation 3x - 8y = -16, we need to rearrange the equation into slope-intercept form, y = mx + b, where m represents the slope.

Starting with the given equation:

3x - 8y = -16

We can isolate y by subtracting 3x from both sides:

-8y = -3x - 16

Next, we divide both sides of the equation by -8 to solve for y:

y = (3/8)x + 2

Now, we can observe that the equation is in slope-intercept form, y = mx + b, with m = 3/8.

This means that for every increase of 1 in the x-coordinate, the y-coordinate increases by 3/8.

The probability that a person who purchased the game did not see the advertisement is:0.659.

what is  probability?

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain. Probability is used in many areas, including statistics, mathematics, science, finance, and gambling.

In the given question,

To solve this problem, we will use Bayes' theorem, which allows us to update our beliefs about the probability of an event based on new information.

Let A be the event that a person has seen the advertisement, and B be the event that a person has purchased the game. We want to find the probability of A given B, i.e., the probability that a person who has purchased the game has also seen the advertisement.

We know that P(A) = 0.24 (24% of the market has seen the advertisement), P(B|A) = 0.42 (42% of those who see the ad have purchased the game), and P(~A|~B) = 0.93 (93% of those who have not seen the advertisement have not purchased the game).

We can use the complement rule to find P(B|~A), the probability of purchasing the game given that the person has not seen the advertisement:

P(B|~A) = 1 - P(~B|~A) = 1 - 0.93 = 0.07

Now we can use Bayes' theorem:

P(A|B) = P(B|A) * P(A) / P(B)

where P(B) = P(B|A) * P(A) + P(B|~A) * P(~A)

Plugging in the values, we get:

P(B) = 0.42 * 0.24 + 0.07 * (1 - 0.24) = 0.2956

P(A|B) = 0.42 * 0.24 / 0.2956 = 0.3408

Therefore, the probability that a person who purchased the game did not see the advertisement is:

1 - P(A|B) = 1 - 0.3408 = 0.659

Rounded to the nearest thousandth, the answer is 0.659.

To find out how much lace Ms. Regan needs to purchase, we first need to calculate the circumference of the circular quilt. We know that the area of the quilt is 28.26 square feet, and we can use the formula A = πr^2 to find the radius of the quilt.

28.26 = 3.14 x r^2

r^2 = 9

r = 3

Now that we know the radius is 3 feet, we can use the formula C = 2πr to find the circumference of the quilt.

C = 2 x 3.14 x 3

C = 18.84 feet

Therefore, Ms. Regan needs to purchase 18.84 feet of lace to go around the outside of her circular quilt.

In summary, to find out how much lace Ms. Regan needs to purchase, we need to calculate the circumference of the circular quilt. We do this by first finding the radius using the formula A = πr^2. Once we know the radius, we can use the formula C = 2πr to find the circumference. In this case, the circumference is 18.84 feet, so Ms. Regan needs to purchase that amount of lace.
