The weights of college football players are normally distributed with a mean of 200 pounds and a standard deviation of 50 pounds

Feliz [49]

Answer:

0.3811 = 38.11% probability that he weighs between 170 and 220 pounds.

Step-by-step explanation:

When the distribution is normal, we use 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:

$\mu = 200, \sigma = 50$

Find the probability that he weighs between 170 and 220 pounds.

This is the pvalue of Z when X = 220 subtracted by the pvalue of Z when X = 170.

X = 220

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

$Z = \frac{220 - 200}{50}$

$Z = 0.4$

$Z = 0.4$ has a pvalue of 0.6554

X = 170

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

$Z = \frac{170 - 200}{50}$

$Z = -0.6$

$Z = -0.6$ has a pvalue of 0.2743

0.6554 - 0.2743 = 0.3811

0.3811 = 38.11% probability that he weighs between 170 and 220 pounds.

Find the geometric mean of 14 and 20.

Tom [10]

Answer:

16.73 to nearest hundredth.

Step-by-step explanation:

The geometric mean of x and y is √xy.

So out geometric mean is √(14*20)

= √280

= 16.7332

8.4 + 0.18x =0.32x what is the value for x

rjkz [21]

Answer:

x = 60

Step-by-step explanation:

to solve this simple expression, you will collect the like terms and then evaluate for the value of x

<u>solution</u>

8.4 + 0.18x =0.32x

8.4 = 0.32x - 0.18x

8.4 = 0.14x

divide both side by the coefficient of x

8.4/0.14 = 0.14x/0.14

60 = x

x = 60

to check if the answer is correct put the value of x = 60 into the question and check if the right handside is equal to the left handside.

8.4 + 0.18x =0.32x

8.4 + 0.18 × 60 = 0.32 × 60

8.4 + 10.8 = 19.2

19.2 = 19.2................................................................................ proved
