Do I add all the GPAs together and then add all the GPAs above Salley and then subtract them from each other?

solong [7]

No you add them all together and then you divide the number of GPA's to get the mean. You go from greatest to lowest to figure out the median and to find the mode excepts my mind. <span />

The time it takes a customer service complaint to be settled at a small department store is normally distributed with a mean of

noname [10]

Answer:

0.0475 = 4.75% probability that a randomly selected complaint takes more than 15 minutes to be settled.

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 10 minutes and a standard deviation of 3 minutes

This means that $\mu = 10, \sigma = 3$

Find the probability that a randomly selected complaint takes more than 15 minutes to be settled.

This is 1 subtracted by the p-value of Z when X = 15, so:

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

$Z = \frac{15 - 10}{3}$

$Z = 1.67$

$Z = 1.67$ has a p-value of 0.9525.

1 - 0.9525 = 0.0475.

0.0475 = 4.75% probability that a randomly selected complaint takes more than 15 minutes to be settled.

Find the area of the rhombus

MAXImum [283]

<h3> Solution :-</h3>

Area of rhombus :-

$\bf \star \: \: \boxed{ \bf \dfrac{d_{1}d_{2}}{2} }$

$\sf \longrightarrow d_{1} = 4 \sqrt{3} + 4 \sqrt{3} = 8 \sqrt{3}$

$\sf \longrightarrow d_{2} = 4 + 4 = 8$

Area of rhombus :-

$: \implies \sf \dfrac{8 \sqrt{3} \times 8 }{2}$

$: \implies \sf 8 \sqrt{3} \times 4$

$: \implies \bf 32 \sqrt{3} \: {m}^{2}$

The volume of dry goods, like apples or peaches, can be measured usings bushels, pecks, and quarts. A bushel contains 4 pecks, a

nata0808 [166]

Answer: For every 1 bushel, there will be 2 quarts

Step-by-step explanation:

If 4:8, then you would have to divide. To find how much bushels there are in a quart, you would need to divide each number by 4. 4/4 = 1. 8/4 = 2. So, the relationship between b:q would be 1:2
