The angle measures in any triangles add up to 180 degrees
Answer: A. z = -2.57
Step-by-step explanation:
Let p be the population proportion of people polled favor the incumbent.
As per given , we have

Sample size : n= 1030
sample proportion : 
Test statistic for proportion : 

Hence, the test statistic is z = -2.57 .
Thus , the correct answer is A. z = -2.57 .
The answer will be $20,000.
The 2 legs of the triangle could be 12 and 9 (they would fit the Pythagoras theorem).
The first choice fits these reuirements
Answer is (-5, 6), (-5, -6) (4,-6)
Answer: y = 1,337.00 + 177.00x
Explanation:
The total pay for the month that Whitney receives is a composition of the fixed salary, $1,337.00, and the commission, $177.00 one ach car she sells.
The commision, in turn is a function of the number of cars that she sells. So the composed function is the sum of two terms: the basic salary and the comissions.
The variables used are:
- dependent variable, total pay for the month: y
- independent variable, number of policies sold: x
Hence, the function is: y = 1,337.00 + 177.00x
