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).

iAnswer: i belive it is 12

Step-by-step explanation: theGCF of 36 and 24 is 12 the GCF of 36 and 48 is 12 and the GCF of 48 and 24 is 12 and 24

PRT TWO: there would be 2 pencils in each bag 3 candy barsin each and 4 erasers in each because 24 divided by 12 = 2 36 divided by 12 = 3 and 48 dividedby 12 = 4

Virty [35]

<span>A+B)^2 is the largest. It is A^2+2AB+B^2, which is clearly greater than the last two options. To compare (A+B)^2 and 2(A+B), we remove one A+B so that we're just comparing A+B and 2. As A+B must be at least 3 (as both must be positive integers, and one must be greater than the other, leading to a minimum value of A=2, B=1), A+B is greater than 2, and as a result, (A+B)^2 is always the largest.</span>
