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

xxTIMURxx [149]
Area=pi*r^2
16/25 therefore is r^2
therefore r=4/5
circumference = 2*pi*r
8*pi/5 is the circumference, C.

Mr. Hinckley owns 83 acres of land, he divides the land into eight equal sections to sell to eight buyers which phrase describes
anygoal [31]

Alright, lets get started.

Mr. Hinckley owns 83 acres of total land.

He divides the land into eight equal sections to sell to eight buyers.

It means, we could find the land each buyer receives by dividing total land by 8.

So, each buyer receives land = \frac{83}{8}

So, each buyer receives land = 10.375 acres

So, the answer is 10.375 acres lands received by each buyer. : Answer

Hope it will help :)
