If there are 26 bags EACH costing $9 then you would use equation A.
26 (The number of gift bags) x the price of each bag would cost close to $234. That would be the reasonable estimate and I hope this helps!

A rectangular prism has a length of 312 in., a width of 5 in., and a height of 112 in.

OLga [1]

Area of prism = area of base * height

= ( 312 * 5 ) * 112 = 174720 cubic inch

Test scores are normally distributed with a mean of 500. Convert the given score to a z-score, using the given standard deviatio

Bond [772]

Answer:

The percentage of students who scored below 620 is 93.32%.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 500, \sigma = 80$
