Answer:
The value for the test statistics = 3.48
Step-by-step explanation:
Given that:
population mean = 75
sample size n = 25
sample mean = 78.48
standard deviation = 5
The value for the test statistics can be computed by using the formula:
z = 3.48
The value for the test statistics = 3.48
The slope of this line is 1 and the y-intercept is -2.
In order to find this, you need to put it in slope intercept form. This is done below for you.
3x - 3y = 6 -----> Subtract 3x from both sides
-3y = -3x + 6 -----> Divide by -3
y = x - 2
Now that you have this, you can find the slope by looking for the coefficient of x. In this case it is 1. You can find the intercept as the constant at the end, which is -2.

This is a similarity and congruence question.
When shapes are similar, their angles are equal but their sizes are proportionate
So we can say this:
Angle GHE or z = Angle CDA
Angle GHE or z = 110
Answer would be 110
Answer:
$85.60
Step-by-step explanation:
We add the percentage of sales tax to the total. This means we are paying 100% + 7% tax, or 107%.
107% = 107/100 = 1.07; this gives us
80(1.07) = 85.60.
