The perimeter and the area of a rectangle have the same numerical value.

Sophie [7]

Formula

2*(L + W) = L * W

Given

W = 3

Solution

2*(L + 3) = 3*L

2L+ 6 = 3L Subtract 2L from both sides

2L - 2L + 6 = 3L - 2L combine

6 = L

Answer: The length is 6 units long.

A researcher obtained M = 27 for a sample of n = 36 scores selected from a population with µ = 30 and σ = 18. This sample mean c

dusya [7]

Answer:

True

Step-by-step explanation:

Given that:

M = 27, sample of n = 36 scores, µ = 30 and σ = 18.

The z score is used in statistics to determine by how many standard deviations the raw score is above or below the mean. If the z score is positive, the raw score is greater than the mean and if the z score is negative the raw score is less than the mean. The z score is given as:

$z=\frac{x-\mu}{\sigma}$

Given that M = 27, this means that x = 27. Therefore:

$z=\frac{x-\mu}{\sigma}\\\\for \ a\ sample\ size(n):z=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\z=\frac{27-30}{18/\sqrt{36} } =\frac{-3}{3}=-1$

This sample mean corresponds to a z-score of z = –1.00.

Which equation is the equation of a line that passes through -10 ,3 and is a perpendicular to Y equals 5X -7

laiz [17]

The slope perpendicular to the one given is the opposite reciprocal. So the slope of the "new" line will be -1/5. Using y = mx + b and filling in 3 for y, -10 for x and the slope, m, of -1/5 will help you solve for b. Then use that b to write the new equation. 3= -1/5(-10) + b and b = 1. Your equation, then, is y = -1/5x + 1
