Given the equation y=23x,whats the value of x if y=100
Damm [24]

Answer: 4.3478 or 100/23

Step-by-step explanation:

Set the y values equal to each other since they are the same unknown (x). You end up with 100=23x, solve for x. Move the 23 over to the other side by using division. x=100/23. If you need it in decimal form, 100÷23=4.347826087

Suppose that you are interested in determining the average height of a person in a large city. You begin by collecting the heigh
monitta

The standard error of the estimate of average height in the city is 0.25.

Given average height 64 inches, sample mean and sample standard deviation of 4 inches.

We have to determine the standard error of the estimate of the average height in the city.

Standard error is the error which is predicted before research to happen in research. It is calculated by dividing the standard deviation of the sample by the square root of the sample size.

n=256

μ=mean

s = sample standard deviation

Standard error=s/\sqrt{n}

=4/\sqrt{256}

=4/16

=0.25

Hence the standard error of the estimate of the average height is 0.25.
