Answer:
44
Step-by-step explanation:
6 times 3 is 18 so.. 18 minus 69 would be -36 plus 12 is a positive 1 times 14 would be 14 minus 7 would be 7 7 times 27 would 38 plus 7 would be 45 minus one would be 44
For the new expectation, 3 drivers and 2 vans are needed.
To determine, for the new expectation, how many drivers and vans do you need, the following calculation must be performed:
- 8500 x 1.5 = 12750
- 5000 x 3 = 15000
Therefore, for the new expectation, 3 drivers and 2 vans are needed.

Answer:
785 acres
Step-by-step explanation:
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Let X represent the random variable amount of corn yield
Assuming the X follows a normal distribution
And we know that the average
is dsitributed:

And we are interested on this probability:

For this case we can use the z score formula given by:

If we apply this we got:

And since we have a proportion estimated and we hava a total of 1200 acres the expected to yield more than 180 bushels of corn per acre would be:

And if we round up this amount we got
and that would be the best option for this case.
