I found 4 because of Pythagorean Theorem on the triangle, which is known as a 345 triangle.

Question 1:

(a) The equation representing Elaine's total parking cost is:

C = x * t

(b) So the cost of parking for a full 24 hours would be 24 times the cost per hour.

Question 2:

The given system of equations is inconsistent and has no solution.

(a) To represent Elaine's total parking cost, C, in dollars for t hours, we need to know the cost per hour. Let's assume the cost per hour is $x.

(b) If Elaine wants to park her car for a full 24 hours, we can substitute t = 24 into the equation from part (a):

C = x * 24

Question 2:

To solve the linear system:

-x - 6y = 5

x + y = 10

We can use the elimination method.

Multiply the second equation by -1 to create opposites of the x terms:

-x - 6y = 5

-x - y = -10

Add the two equations together to eliminate the x term:

(-x - 6y) + (-x - y) = 5 + (-10)

-2x - 7y = -5

Now we have a new equation:

-2x - 7y = -5

To check the answer, we can substitute the values of x and y back into the original equations:

From the second equation:

x + y = 10

Substituting y = 3 into the equation:

x + 3 = 10

x = 10 - 3

x = 7

Checking the first equation:

-x - 6y = 5

Substituting x = 7 and y = 3:

-(7) - 6(3) = 5

-7 - 18 = 5

-25 = 5

The cricketer's average for the last 10 innings was 15.67 runs per innings (approx.).

The average for the last 10 innings, we need to follow these steps:

Calculate the total runs scored in the first 20 innings. Total runs scored = Average * Number of innings = 15 * 20 = 300

Calculate the total runs scored in the next 10 innings. Total runs scored = Average * Number of innings = 17 * 10 = 170

Calculate the total runs scored in all 30 innings. Total runs scored = 300 + 170 = 47

Calculate the average for all 30 innings. Average = Total runs scored / Number of innings = 470 / 30 = 15.6

Calculate the total runs scored in the last 10 innings. Total runs scored = Average * Number of innings = 15.67 * 10 = 156.7 (approx.)

Calculate the average for the last 10 innings. Average = Total runs scored / Number of innings = 156.7 / 10 = 15.67

Therefore, the cricketer's average for the last 10 innings was 15.67 runs per innings (approx.).

Step-by-step explanation:

If A is the X-coordinate of a pre-image point, and B is the X-coordinate of the image, then we want 4 to be the midpoint of those values. That is ...

  (A + B)/2 = 4

  A + B = 8 . . . . . multiply by 2

  B = 8 - A . . . . .  subtract A

So, the reflection over x=4 is the transformation ...

  (x, y) ⇒ (8 -x, y)

The y-value stays the same, and the new x-value is the result of subtracting the x-coordinate from 8.

Answer:

Step-by-step explanation:

The probability of drawing a number that is divisible by 3 is 1/3, since there are 3 numbers (3, 6, and 9) out of the 9 possible numbers (1, 2, 3, 4, 5, 6, 7, 8, and 9) that are divisible by 3.

The probability of drawing a 1 after drawing a number that is divisible by 3 is 1/10, since there is only one 1 among the 10 possible digits (0-9) that could be drawn after the first number.

To find the probability of both events happening together (drawing a number divisible by 3 and then drawing a 1), we need to multiply the probability of the first event by the probability of the second event. Therefore, the probability of drawing a number divisible by 3 and then drawing a 1 is:

(1/3) x (1/10) = 1/30

So the probability of drawing a number divisible by 3 and then drawing a 1 is 1/30, or approximately 0.0333, or about 3.33%

Answer:

7.5

Step-by-step explanation:

The perimeter of the regular pentagon will be 7.5 units.

All the sides of the regular polygon are congruent to each other. The perimeter of the regular polygon of n sides will be the product of the number of the side and the side length of the regular polygon.

P = (Side length) x n

The sides of the regular polygon are 3(x - 1) and (5x - 6). Then the value of the variable x will be

3(x - 1) = 5x - 6

3x - 3 = 5x - 6

2x = 3

x = 1.5

Then the side length of the regular pentagon will be

Side = 3(1.5 - 3)

Side = 3 (0.5)

Side = 1.5

Then the perimeter of the regular pentagon will be

P = 5 x 1.5

P = 7.5 units

The perimeter of the regular pentagon will be 7.5 units.

The correct calculation of the standard deviation of the sampling distribution of p_hat subscript s - p_hat subscript p is 0.0934.

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of population

N = number of observation of population

X = mean

μ = population mean

We are given that;

Percentage of students with laptop=68%

Percentage of professors with laptop=43%

p_s = 0.68 and p_p = 0.43.

Now,

The formula for the standard deviation of the sampling distribution of the difference between two sample proportions is:

sqrt[(p_s * (1 - p_s) / n_s) + (p_p * (1 - p_p) / n_p)]

where p_s and p_p are the population proportions of students and professors who have a laptop, respectively, n_s and n_p are the sample sizes of students and professors, respectively.

We are also given that 56 students and 31 professors were selected at random and asked if they have a laptop. Therefore, n_s = 56 and n_p = 31.

Substituting these values into the formula, we get:

sqrt[(0.68 * (1 - 0.68) / 56) + (0.43 * (1 - 0.43) / 31)]

sqrt[0.00367143 + 0.00505484]

= sqrt(0.00872627)

= 0.0934 (rounded to four decimal places)

Therefore, by standard deviation the answer will be 0.0934.

The correct option is C) 48.9 units. To find the perimeter of the equilateral triangle, we first need to determine the length of one side of the triangle. Since the triangle is equilateral, all three sides are of equal length.

We can use the distance formula to find the length of one side of the triangle. Let's choose the two vertices located at (-8, -5) and (3, 7) to find the distance between them.

Distance between (-8, -5) and (3, 7) = √[(3 - (-8))² + (7 - (-5))²]

= √[11² + 12²]

= √(121 + 144)

= √265

Since the triangle is equilateral, all three sides are of the same length, so the length of one side of the triangle is also √265.

Therefore, the perimeter of the triangle is 3 times the length of one side:

Perimeter = 3 × √265

= 48.91 (rounded to two decimal places)

Therefore, the correct option is C) 48.9 units.

Answer:

Cos z is 28/35

Step-by-step explanation:

The value of 14.5% of 1,800 is 261 by using the concept of percentage.

In mathematics, a percentage is a value or ratio expressed as a fraction of 100.

The term percent is derived from the Latin per centum, which means "hundred" or "by the hundred." The sign for "percent" comes from the Italian expression per cento, which means "for a hundred." The "per" was frequently shortened as "p." and finally disappeared entirely. The "cento" was reduced to two circles divided by a horizontal line, from which the present "%" symbol was derived.

A % is a relative figure that indicates one-tenth of a quantity. One percent (symbolized 1%) is the one-hundredth part; consequently, 100 percent denotes the complete amount, and 200 percent specifies twice the supplied amount.

Given,

14.5% of 1,800

What is fractional equivalent?

Equivalent fractions are fractions with distinct numerators and denominators but the same value.

1. The number represented by n has two repeating digits, 15.

2. To convert the repeating decimal to a fraction, we need to identify the place value of the repeating digits. In this case, the repeating digits start immediately after the decimal point, so we need to multiply by a power of 10 that is equal to the number of repeating digits, which is 2.

3. Power of 10 times n = 10^2 x 0.1515... = 15.15...

        \(0.1515... x 10^2 = 15.15...\\\\\)

4.

       \(10^2n = 15.15...\\\\n = 0.1515...\\\\99n = 15\)

To obtain the equation, we multiplied the original bby 100 to eliminate the decimal, which gives 100n = 15.1515... We then subtracted the original equation from the multiplied equation to eliminate the repeating digits, which gives 99n = 15.

5. 99n = 15

n = 15/99

To obtain the fraction, we divided both sides of the equation by 99.

Therefore, the fractional equivalent of the repeating decimal n = 0.1515... is 15/99, which can be simplified to 5/33 in simplest form.

Step-by-step explanation:

The value of x in the secant intersection is 4.

If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.

Therefore, let's find the value of x using the secant intersection theorem as follows;

4(4+x + 2) = 5(5 + x - 1)

4(6 + x) = 5(4 + x)

24 + 4x = 20 + 5x

24 - 20 = 5x - 4x

Answer:

The test statistics is  \(z =  -1.56 \)  

The p-value is   \(p-value =  0.05938 \)

Step-by-step explanation:

From the question we are told  

   The West side sample  size is \(n_1  =  578\)

    The  number of residents on the West side with income below poverty level is \(k  = 76\)

    The East side sample size  \(n_2=688\)

  The  number of residents on the East side with income below poverty level is \(u  = 112\)

   The null hypothesis is  \(H_o  :  p_1 = p_2\)

    The alternative hypothesis is  \(H_a :  p_1 <  p_2\)

Generally the sample proportion of  West side is  

     \(\^{p} _1 = \frac{k}{n_1}\)

=>   \(\^{p} _1 = \frac{76}{578}\)

=>   \(\^{p} _1 =  0.1315 \)

Generally the sample proportion of  West side is  

     \(\^{p} _2 = \frac{u}{n_2}\)

=>   \(\^{p} _2 = \frac{112}{688}\)

=>   \(\^{p} _2 =  0.1628 \)

 Generally the pooled sample proportion is mathematically represented as

    \(p = \frac{k + u}{ n_1 + n_2 }\)

=>  \(p = \frac{76 + 112}{ 578 + 688 }\)

=>  \(p =0.1485\)

Generally the test statistics is mathematically represented as

\(z = \frac{\^ {p}_1 - \^{p}_2}{\sqrt{p(1- p) [\frac{1}{n_1 } + \frac{1}{n_2}  ]}  }\)

=> \(z = \frac{ 0.1315  - 0.1628 }{\sqrt{0.1485(1-0.1485) [\frac{1}{578} + \frac{1}{688}  ]}  }\)  

=> \(z =  -1.56 \)  

Generally the p-value  is mathematically represented as

          \(p-value =  P(z <  -1.56 )\)

From z-table  

         \(P(z <  -1.56 ) =  0.05938\)

So

     \(p-value =  0.05938 \)
