TEA [102]

None of these answers match up to the equation. The answer is 2. 2^2, 2x2=4
4+4=8

If the label of a can of yams were cut off and laid flat, which expression would give the area, A, of the label with the measure

Damm [24]

I think you are missing information to solve this problem. Should there me an image attached to this question.

Either way, to solve for the label, the label would most likely me a rectangle when laid flat.

It's dimensions would be length x height.

Where height is most likely "h"
and
length is most likely the circumference (2πr)

Thus the possible answers are either:

B or C

I can't answer it until I see an image when more detail.

Hope this helps!

The capacity of an elevator is 12 people or 2088 pounds. the capacity will be exceeded if 12 people have weights with a mean gre

boyakko [2]

suppose the people have weights that are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.

Find the probability that if a person is randomly selected, his weight will be greater than 174 pounds?

Assume that weights of people are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.

Mean = 177

standard deviation = 26

We find z-score using given mean and standard deviation

z = $\frac{x-mean}{standard deviation}$
