Answer:

v in (-oo:+oo)

1.13/64 = (11/8)*v // - (11/8)*v

1.13/64-((11/8)*v) = 0

(-11/8)*v+1.13/64 = 0

0.01765625-11/8*v = 0 // - 0.01765625

-11/8*v = -0.01765625 // : -11/8

v = -0.01765625/(-11/8)

v = 0.01284091

v = 0.01284091

1 13/64 = 11/8x

Rewrite the left side as an improper fraction:

77/64 = 11/8x

Divide both sides by 11/8

77/11 = 7

64/8 = 8

X = 7/8

The mean weight of frozen yogurt cups in an ice cream parlor is 8 oz.Suppose the weight of each cup served is normally distribut
vaieri [72.5K]

Answer:

10.03% probability of getting a cup weighing more than 8.64oz

Step-by-step explanation:

Problems of normally distributed samples are 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 question, we have that:

\mu = 8, \sigma = 0.5

What is the probability of getting a cup weighing more than 8.64oz

This is the 1 subtracted by the pvalue of Z when X = 8.64. So

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

Z = \frac{8.64 - 8}{0.5}

Z = 1.28

Z = 1.28 has a pvalue of 0.8997

1 - 0.8997 = 0.1003

10.03% probability of getting a cup weighing more than 8.64oz
