subtract the total cost from the money he paid with

100-54.38 = 45.62 in change

Take 100 and subtract 54.38 from it and you get 45.62 so He will receive $45.62 change

The number of chocolate chips in a popular brand of cookie is normally distributed with a mean of 22 chocolate chips per cookie

MA_775_DIABLO [31]

Answer:

The cutoff numbers for the number of chocolate chips in acceptable cookies are 16.242 and 27.758

Step-by-step explanation:

Problems of normally distributed samples can be 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 problem, we have that:

$\mu = 22, \sigma = 3.5$

Middle 90%

Between the 50 - (90/2) = 5th percentile to the 50 + (90/2) = 95th percentile.

5th percentile:

X when Z has a pvalue of 0.05. So X when Z = -1.645.

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

$-1.645 = \frac{X - 22}{3.5}$

$X - 22 = -1.645*3.5$

$X = 16.242$

95th percentile:

X when Z has a pvalue of 0.95. So X when Z = 1.645.

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

$1.645 = \frac{X - 22}{3.5}$

$X - 22 = 1.645*3.5$

$X = 27.758$

The cutoff numbers for the number of chocolate chips in acceptable cookies are 16.242 and 27.758

With a fair die, the probability of rolling any number 1 through 6 is the same.

yaroslaw [1]

The probability of all possible outcomes is always 1, meaning 100%.

In this case the probability of rolling a 1,2,3,4,5, or 6 is:

1/6+1/6+1/6+1/6+1/6+1/6

6(1/6)

6/6
