How many people aspire to become entrepreneurs if the total is 360 people? Doctor : 65% Police : 5% Pilot : 20% ENTREPENEURS????

KatRina [158]

Answer: 36 people

Step-by-step explanation:

1. The number of people that aspire to become doctor is:

360 people*0.65=234 people

2. The number of people that aspire to become police is:

360 people*0.05=18 people

3. The number of people that aspire to become pilot is:

360 people*0.2=72

4. The sum of people that do not aspire to become entrepreneurs is:

234 people+18 people+72 people=324 people

5. Therefore, the number of people that aspire to become entrepreneurs is:

360 people-324 people=36 people

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:

$\mu = 8, \sigma = 0.5$
