Answer:

x = -3.7

Step-by-step explanation:

so in this equation we are trying to find the variable x and to do so we have only have the variables on one side of the equal sign and numbers on the other. SO the equation is:

-8.3 + x = -12

So we are going to only have x on the left side of the equal sign, so we are going to add 8.3 to -8.3 and -12 because what you do to one side you do to the other:

-8.3 + x = -12

+8.3 +8.3

to make the equation look like this:

x = -3.7

Now to check our work we are going to replace where the x variable is in the equation -8.3 + x = -12 with -3.7

-8.3 + (-3.7) = -12

-12 = -12

Hope this helps!!!

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:

$\mu = 190, \sigma = 30$
