Step-by-step explanation:
The z statistics is given by:

In which X is the found proportion, p is the expected proportion, and s, which is the standard error is 
Out of 53 teachers who replied to the survey, 13 claim they are satisfied with their job.
This means that 
She find that the proportion of satisfied teachers nationally is 18.4%.
This means that 
Standard error:
p = 0.184, n = 53.
So

Z-statistic:



The correct answer is:
b. 1.15
Answer:
The correct answer is (-3,-1) (0,5) (3,11)
Step-by-step explanation:
Emma's mistake was flipping her y-values, 11 matches with 3, not -3. The most likely reason she did this was accidentally making the slope negative. The table she wrote fits the line y=-2x+5. If you plug in -3 into the correct equation you will get -1 and 3 will get you 11.
It’s negative slope since it’s going to the left

Answer:
<h3>-90</h3>
Step-by-step explanation:
To use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) left to right.
Please Excuse My Dear Aunt Sally!
BOMDAS- (Brackets, Of, Multiply, Divide, Add, and Subtract) from left to right.
First, do parenthesis.
(3-21)=-18
-18(3+2)
Add.
3+2=5
-18*5
Multiply.
-18*5=-90
-90
So, the final answer is -90.
