If the mean of a normally distributed population is -10 with a standard deviation of 2, what is the likelihood of obtaining a va
ira [324]

Answer:

93.32% probability of obtaining a value less than or equal to -7.

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 = -10, \sigma = 2

What is the likelihood of obtaining a value less than or equal to -7?

This is the pvalue of Z when X = -7.

So

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

Z = \frac{-7 -(-10)}{2}

Z = \frac{3}{2}

Z = 1.5

Z = 1.5 has a pvalue of 0.9332.

So there is a 93.32% probability of obtaining a value less than or equal to -7.

Mary bought more than 72 pencils to distribute to children at an orphanage. She packs these pencils in gift boxes. If she packs
bixtya [17]
For this case, the first thing we must do is define a variable.
 We have then:
 x: number of gift boxes.
 We then have to write the inequation that models the problem:
 "Mary bought more than 72 pencils"
 "she packs 4 pencils each into x gift boxes"
 We have then:
 4x \geq 72
 Simplifying we have:
 x \geq 72/4
 x \geq 18
 Answer:
 
the inequality that represents this situation is:
 4x \geq 72
 The simplified form of the inequality is:
 
x  \geq 18

XZ = 15 and the perimeter of XWZ is 50. What is the length of WZ?
Rom4ik [11]

Answer:

  17.5

Step-by-step explanation:

The perimeter is the sum of the side lengths:

  perimeter = XZ +WZ +WX

The figure shows us WX = WZ, so we can rewrite the formula as ...

  perimeter = XZ +2·WZ

Filling in the given values, this becomes ...

  50 = 15 + 2·WZ

  35 = 2·WZ

  35/2 = WZ = 17.5

The length of WZ is 17.5 units.
