Answer:
The dimensions of the iphone are 2 inches by 7 inches.
Step-by-step explanation:
Given that,
The dimensions of an iPhone are x – 2 and x + 3.
The area of an iphone is 14 sq inches
We need to find the dimensions of the iPhone. It is in the shape of a rectangle. Its area is given by :
Neglecting negative value
First dimension = (x-2) = (4-2) = 2 inches
Other dimension = (x+3) = (4+3) = 7 inches
Hence, the dimensions of the iphone are 2 inches by 7 inches.
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.
