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

There are different types of parallelograms,and you probably have the notes determining what type it is. So like it could be a square, rectangle, rhombus..

One gallon of milk contains 128 fluid oz. how many 8 oz cups will one gallon contain?

HACTEHA [7]

There are 8 ounces in a cup.

To find how many cups are in a gallon of milk, divide the ounces in a gallon by the ounces in a cup:

$128 \div 8 = 16$

A gallon will contain 16 eight-ounce cups.

The Mayors of two small towns that adjoin a large community have engaged in an argument on which of their cities is safer, with

Lelu [443]

Answer:

1. City A: 150 violent crimes per 100,000 residents.

City B: 161 violent crimes per 100,000 residents.

2. City A

Step-by-step explanation:

City A:

Population = 123,000

Violent crimes = 185

Violent crimes per 100,000 people:

$V_{100k} = \frac{185*100,000}{123,000} \\V_{100k} = 150$

City B:

Population = 84,000

Violent crimes = 135

Violent crimes per 100,000 people:

$V_{100k} = \frac{135*100,000}{84,000} \\V_{100k} = 161$

1. City A: 150 violent crimes per 100,000 residents.

City B: 161 violent crimes per 100,000 residents.

2. Even though it has a bigger number of crimes, City A has the lowest crime rate since its population is larger.
