\dfrac{32}{x}=\dfrac{192}{36}\qquad\text{cross multiply}\\\\192x=(32)(36)\qquad\text{divide both sides by 192}\\\\x=\dfrac{1152}{192}\\\\\boxed{x=6}

Assume that the distribution of weights of adult men in the United States is normal with mean 190 pounds and standard deviation
avanturin [10]

Answer:

182.41

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 = 190, \sigma = 30

40th percentile

Value of X when Z has a pvalue of 0.4. So X when Z = -0.253.

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

-0.253 = \frac{X - 190}{30}

X - 190 = -0.253*30

X = 182.41

So the answer is 182.41.

Hey!


1 car is $3.83.

3 cars is $3.83 × 3


3.83 × 3 = 11.49


Shipping fee is $4.55. Add that to the price of the 3 cars


11.49 + 4.55 = 16.04


The girls share the cost equally. Divide by 2


16.04 ÷ 2 = 8.02
