salantis [7]
The ratio between the departments is

A: B: C
15000 : 18000 : 9000
15 : 18 : 9
5 : 6 : 3

The budget needs to be divided into 5+6+3 = 14 parts
The budget for one part is 22000/14

The budget for department B is \frac{22000}{14}*6=9428.571428
Rounded to the nearest dollar, the budget is $9429

The mean annual inflation rate in the United States over the past 98 years is 3.37% and has a standard deviation of approximatel
Ksenya-84 [330]

Answer:

38.59% probability that inflation rate will be below 1.9% in 2019

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 problem, we have that:

\mu = 3.37, \sigma = 5

If the annual inflation rate is normally distributed, what is the probability that inflation rate will be below 1.9% in 2019?

This is the pvalue of Z when X = 1.9. So

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

Z = \frac{1.9 - 3.37}{5}

Z = -0.29

Z = -0.29 has a pvalue of 0.3859

38.59% probability that inflation rate will be below 1.9% in 2019
