There was $135 in Roland's bank account after the two-month period.

Step-by-step explanation:

Step 1:

Roland out $180 in his account at the beginning of July. This reduced by 25% over the next two months.

We need to determine how much 25% of $180 is. To do so we convert 25% into a fraction and multiply with 180.

25% of $180 =\frac{25}{100}  (180)= 45.

So an amount of $45 reduced over two months.

Step 2:

To calculate the money Roland has in his account after two months, we subtract the amount reduced from the amount of money in his account at the beginning of July.

The amount of money in his bank account after the two-month period 180-45= 135.

So there was $135 in Roland's bank account after the two-month period.

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).

MrMuchimi

Answer:

Infinite Solutions

Step-by-step explanation:

If you distribute the left side of the expression, you will get 3y -32, which is exactly the same as the right side of the equation. Since both lines are the same, that means that they have an infinite amount of solutions. Therefore, the 4th choice is correct.
