Answer:

Step-by-step explanation:

In a multiple regression model X1 and X2 are two independent variables and the assumption is made that the effect of of X1 and X2 on dependent variables is independent of each other.For example let y be the student grade and x1 is the study hour and x2 be the IQ level of student so the multiple regression model for this scenario will be

Y=b0+b1x1+b2x2+e

Hence we can see that effect of study hour and IQ level on the student grade and the effect of study hour on the student grade is independent of the value of IQ level.

<u>The correct answer is D. 650.oo, 661.70, 673.61, 685.74, 698.08</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Compound interest rate charged by Miriam's credit card company = 1.8% monthly

2. If she makes no purchases or payments, she will go more and more in debt. Which of the following sequences describes her increasing monthly balance?

Miriam's current credit card balance = US$ 650

Miriam's credit card balance in one month = 650 * 1.018

Miriam's credit card balance in one month = 661.70

Miriam's credit card balance in two months = 661.70 * 1.018

Miriam's credit card balance in two months = 673.61

Miriam's credit card balance in three months = 673.61 * 1.018

Miriam's credit card balance in three months = 685.74

Miriam's credit card balance in four months = 685.74 * 1.018

Miriam's credit card balance in four months = 698.08

<u>The correct answer is D. 650.oo, 661.70, 673.61, 685.74, 698.08</u>
