13 1/8 and as a decimal it’s 13.125
Answer:
We use the one sample t test for this
Step-by-step explanation:
In this question, we are to determine if there is sufficient evidence to conclude that mean amount of milk in cartons is less than 32 ounces.
What we will use to determine if there is sufficient evidence is the t-test.
why?
we will have to to use t test because the hypothesis is on the mean and sample size is less than 30 i.e 22 < 30
For a better understanding of the answer please find the diagram in the attachment.
As can be clearly seen from the diagram that the distance, "d" (shown in dark blue) of 100 feet which is covered on the sloped/inclined road is actually making an angle of only 30 degrees with the force of 200 pounds which is being applied on the road. That angle of 30 degrees is what matters.
So, the force, F=200 pounds
distance, d=100 feet
And the angle between the force, F and the distance, d is:
Therefore, as per formula, the work, W, done will be:
This, when applied to the question we have will give us:
25 is 25% of 100
Therefore you need to find 1/4 (25%) of 1/2
1/4 of 1/2 is .125 or 1/8
