Answer:
6.96 hours.
Step-by-step explanation:
First, we need to find out the hour rate of bushels picked for each of them.
If Imani can pick 40 bushels in 15 hours, then he picks 40/15 = 8/3 bushes per hour.
If Bill can pick 40 bushels in 13 hours, then he picks 40/13 bushes per hour.
Working together, they pick: 
bushes per hour.
Let's simplify this expression:
= 5.74
Now we can use a rule of three
1 hour -------5.74
x hours ------40
Then,
x = 40 / 5.74 = 6.96
Therefore, it would take them 6.96 hours working together.
Answer:
Here the most appropriate answer is '>'
Thus it will be 0.248<u> > </u>0.259
18, you have 3 choices for the bottom because you can't use the small one, 3 choices for the next because you can now use the small one, 2 for the next and finally 1. You multiply all of them to get 18
Answer:
Zscore = 0.5
Step-by-step explanation:
If we assume a normal distribution, we mean that the diameters of each tomato follow a normal distribution. This is N~ (0,1).
By that, we mean that the mean (μ) = 0 and variance (
) = 1. Thus, since we are told that one tomato was in the 50th percentile. This implies the median. And is 0.5. And if the distribution is normal, the mean and median and mode should be equal.
Thus:
==> Z score = 
=
