Hello there! I think it is a) 59%. So what I did is add all the numbers 51, 23, and 12 all together. So then I did 100/86= 1.162279068767. Then I did 1.162279068767*51= 59%(approximately).(That is only for the frequently!)

For both of them together it would be 86%( I rounded) So I did 1.162279068767*23. Then I add the 59%+26%= 86. That is how I got the answer.

I hope it helps.

Chapter 7, Section 7.2, Question P9 The process for manufacturing a ball bearing results in weights that have an approximately n

bogdanovich [222]

a. Let $X$ be a random variable representing the weight of a ball bearing selected at random. We're told that $X\sim\mathcal N(0.15,0.005^2)$ , so

$\mathrm P(X$

where $Z\sim\mathcal N(0,1)$ . This probability is approximately

$\mathrm P(Z$

b. Let $X_i$ be a random variable representing the weight of the $i$ -th ball that is selected, and let $Y$ be the mean of these 4 weights,

$Y=\dfrac{X_1+X_2+X_3+X_4}4$

The sum of normally distributed random variables is a random variable that also follows a normal distribution,

$X_1+X_2+X_3+X_4\sim\mathcal N(4\cdot0.15,4\cdot0.005^2)$

so that

$Y\sim\mathcal N(0.15,0.005^2)$

Then

$\mathrm P(Y$

c. Same as (b).

A family paid $26.400 as a down payment for a home. If this represents 16% of the price of the home, find the price of the home.

Vlada [557]

The correct answer is:

How to find X if P percent of it is Y. Use the percentage formula Y/P% = X

Convert the problem to an equation using the percentage formula: Y/P% = X
Y is 26,400, P% is 16%, so the equation is 26,400/16% = X
Convert the percentage to a decimal by dividing by 100.
Converting 16% to a decimal: 16/100 = 0.16
Substitute 0.16 for 16% in the equation: 26,400/0.16 = X
Do the math: 26,400/0.16 = X
X = 165,000
So $ 165,000 is the price of the home.

I hope this helps you!!
