Answer:
Range = 0,1,2,3,4
B
Step-by-step explanation:
The range is the set of y values for every corresponding x. -4 is a member of the domain (x values) and that means A C and D are all incorrect.
B is the only one that does not begin with - 4 so B is the right answer.
What you have is slope intercept form(best for graphing)
Ax+By=C and A must be positive
-1x+y = -8
so now A is negative so we multiply by another negative
1x-y = 8
The rest of the numbers can be negative and that is standard form.
<h2>
Answer with explanation:</h2>
Let
be the population mean.
As per given we have,
, since alternative hypothesis is right tailed , so the test is a right-tailed test.
Test statistic : 
For, n=80
, we have

Critical z-value at
=1.645
Since the test statistic value is greater than the critical z-value, so we reject the null hypothesis, i.e. alternative hypothesis is accepted.
Conclusion: We have enough evidence to support the claim that the mean work week has increased for women at the 5% level.
Answer:
8
Step-by-step explanation:
8 is the digit after 7 and previous to 9
We have P = 3 x a (the formula of the perimeter); 26 = 3 x a ; we obtain a = 26/3;
Then, we have <span>the Pythagorean Theorem in one of two rectangular and congruent triangles :</span>
h² = a² - (a/2)² = a² - a²/4 = 4a²/4 - a²/4 =<span> 3a²/4</span>
It follows that
h = √(3a²/4) = a√3/2 ≈ 0,866*a ≈ 7,5 centimeter.
