Answer:
Each comic booke was $3.50
Step-by-step explanation:
You just have to divide 21 by 6
(3^3 - 9 )^2
First do what is inside the parenthesis:
3^3 = 27
Now you have:
(27-9)^2
Subtract:
27-9 = 18
Now you have:
(18)^2
Raise 18 to the second power:
18^2 = 324
Let

be the random variable for the weight of any given can, and let

and

be the mean and standard deviation, respectively, for the distribution of

.
You have

Recall that for any normal distribution, approximately 99.7% of it lies within three standard deviations of the mean, i.e.

. This means 0.3% must lie outside this range,

. Because the distribution is symmetric, it follows that

.
Also recall that for any normal distribution, about 95% of it falls within two standard deviations of the mean, so

, which means 5% falls outside, and by symmetry,

.
Together this means

Solving for the mean and standard deviation gives

and

.
Itd be 1, because the other ones aren’t possible
