Answer:
The results are likely invalid because it is unlikely that the tires installed in one hour on Monday will represent the entire population of tires.
Step-by-step explanation:
Out of 8 hours, do you really think one hour will represent it all?
This is why the resutls are likely invalid ( also I took the quiz )
Answer: The results are likely invalid because it is unlikely that the tires installed in one hour on Monday will represent the entire population of tires.
We can use Law of Cosines to solve for the angle of Z. The solution is shown below:
cos C=(a²+b²-c²)/2ab
cos Z = (yz² + xz² - xy² )/2*yz*xz
cos Z = (20² + 25 - 13²)/2*20*25
cos Z = 856 / 1000
Z=31.13°
The answer is angle 31.13°.
6 and a half feet is equal to 78 inches. If she buys a 77 inch shelf, there is 1 inch between the window and the shelf.
The surface area of the box is being referred to as A
The surface area will be the sum of the four rectangular sides' areas and the base area.
Base area = x²
Rectangular side area = xh
A = x² + 4xh
Volume is, as you said,
V = x²h
Lets substitute h from the formula of A to obtain A in our final answer. Substituting x is possible, but more difficult
(A - x²)/4x = h
V = (x²) * (A - x²)/4x
V = (Ax - x³)/4
Answer:
We failed to accept null hypothesis
Step-by-step explanation:
x= 5.74
Standard deviation = 
n = 65
We will use z test
Formula : 
Substitute the values :
Refer the z table for p value
p value = 0.0314
α = 0.10
p value < α
So, we failed to accept null hypothesis
