R + 3 1/2 = -4 2/3 what does r equal

1 answer:

6 0

$R+3\frac{1}{2}=-4\frac{2}{3}\ \ \ \ | subtract\ 3\frac{1}{2}\\\\
R=-4\frac{2}{3}-3\frac{1}{2}\ \ \ | make\ a\ common\ denominator\\\\
R=-4\frac{4}{6}-3\frac{3}{6}\\\\
R=-7\frac{7}{6}=-8\frac{1}{6}\\\\Solution:\ R=-8\frac{1}{6}$

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:

$\mu = 190, \sigma = 30$
