12 out of 18. This is because there is 6 red marbles and 18 of them all together. The question states the probability of the red marble NOT being chosen therefore you need to take away 6 from 18 leaving you with 12. I hope this made sense :)

DiKsa [7]

Answer:

7x+1 ≤12

Step-by-step explanation:

The common letter used to represent a variable is x. Thus, a 7 is added to it to signify that it is being multiplied. Then, increased by one means +1. At most is a fancy word for less than or equal to ( ≤).

The ages of adults in a certain community follow a normal distribution with mean 38 and standard deviation 6. The random variabl
nataly862011 [7]

Answer:

a = 33.32

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 = 38, \sigma = 6

P(32 < x < a) = .0590

This is the pvalue of Z when X = a subtracted by the pvalue of Z when X = 32.

X = 32

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

Z = \frac{32 - 38}{6}

Z = -1

Z = -1 has a pvalue of 0.1587

X = a

p - 0.1587 = 0.0590

p = 0.0590 + 0.1587

p = 0.2177

So when X = a, Z has a pvalue of 0.2177. So when X = a, Z = -0.78.

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

-0.78 = \frac{X - 38}{6}

X - 38 = -0.78*6

X = 33.32

So a = 33.32
