hope this helped.
have a great day!
I seef(x) between 0 to 1 is goes to xfinity but in the negative direction
We can say it is large neagtive numbet when x is between 0 and 1
Answer:
± 1.96 and the same as for a two-tailed z test at a 0.05 level of significance.
Step-by-step explanation:
We are given the following information in the question:
We perform a two-tailed hypothesis at a 0.05 level of significance.
We have to state the critical values for the same.
Z-critical:
T-critical:
The critical value for t depends upon the degree of freedom which is obtained from the sample size.
If n is the sample size, then , n - 1 is the degree of freedom.
which is the same as the z-critical
Answer:
Area = 245 ft
(Width
Step-by-step explanation:
l = 5w
Where l is length and w is width.
We also know that the perimeter is 84 ft, so:
2l + 2w = 84
Now we can plug in 5w for l since we found the equality earlier:
2(5w) + 2w = 84
and then solve for w:
10w + 2w = 84
12w = 84
w = 7
so
l = 5 × 7
l = 35
The length is 35 and width is 7 so
the area of the rectangle is
