I think it’s A from what I can remember
The answer i got is a standard positive 8
Answer:
The value of test statistic
|Z| = |-2.2883| = 2.2883
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the mean of the Population = 57.7miles/gallon
The standard deviation of the Population = 1.9
The mean of sample x⁻ = 57.4
Given that the sample size 'n' =210
level of significance = 0.1
<u><em>Step(ii):-</em></u>
Test statistic


Z = -2.2883
|Z| = |-2.2883| = 2.2883
<u><em>Final answer:-</em></u>
The value of test statistic
|Z| = 2.2883
The point-slope formula:

We have the points (-4, -1) and (5, 7).
Substitute:

Answer:
{(-6,-6), (-2,-2), (7,-6), (-5,0)}
Step-by-step explanation:
Function: Every domain (x-value) has only one range (y-value)
The other choices had an x-value that had more than one y-value, which makes only this one a function.
Hope this helped :)
