Answer:
B
Step-by-step explanation:
The secant- tangent angle b is half the difference of the measures of the intercepted arcs , then
b =
( 180 - 35) =
× 145° = 72.5° → B
Answer:
The standard error for the sampling distribution is 1.323.
Step-by-step explanation:
Let <em>X</em> = scores of girls and <em>Y</em> = scores of boys.
The information provided is:

As the population standard deviations are not known, use a pooled standard deviation to estimate the standard error of the sampling distribution.
The formula of pooled standard deviation is:

Compute the standard error for the sampling distribution as follows:

Thus, the standard error for the sampling distribution is 1.323.
M < 1 + m < 2 = 90.....its 90 because u have a right angle which is 90 degrees
18 + m < 2 = 90
m < 2 = 90 - 18
m < 2 = 72
