Blizzard [7]

Answer: Jane needs 1 11/ 12 cups of flour more to make the cookie dough

Step-by-step explanation:

Recipe for cookie dough= 3 2/3cups of flour

Amount of flour available for Jane = 1 3/4 cups of flour

Amount of flour Jane needs to add to make cookie dough

=3 2/3 - 1 3/4

changing to improper fraction to make it easier to subtract

11/3 -7/4 = (44- 21)/12 = 23/12  =  1  11/12  cups of flour

Pepsi [2]

Answer:

She should offer a guarantee of 13.76 years.

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 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.

The average life of a certain type of small motor is 10 years with a standard deviation of 2 years.

This means that \mu = 10, \sigma = 2

If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer?

She should offer the 100 - 3 = 97th percentile as a guarantee, so X when Z has a pvalue of 0.97, that is, X when Z = 1.88.

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

1.88 = \frac{X - 10}{2}

X - 10 = 2*1.88

X = 13.76

She should offer a guarantee of 13.76 years.
