Answer:
False. They will be parallel to each other
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 .

You add the LIKE terms together.
The number of solutions of the equations can't be determined.
<h3>How to illustrate the information?</h3>
It should be noted an equation shows the relationship between the variables. It should be noted that the question is to find the number of solutions.
From the information, 3(5x + 2) = 15x
15x + 6 = 15x
Collect like terms
15x - 15x = - 6
0 = -6
Therefore, it can be see that the friend is incorrect as the number of solutions of the equations can't be determined.
