Answer:
$600 interest will be paid in the first 5 years
Step-by-step explanation:
Simple interest is calculated only on the principal or initial amount deposited. Jim deposits 6000 into an account that pays simple interest at a rate of 2% per year. The formula for simple interest is expressed as
I = PRT/100
Where
I represents interest after the given time.
R represents the interest loan on the principal.
T represent number of time in years.
P represents principal or initial amount deposited.
From the information given,
R = 2
P = 6000
T = 5
I = (6000 × 2 × 5)/100 = $600
Answer:
a. $9,425.10
b. $3,707.60
Step-by-step explanation:
Answer:
A. Increase by 2
Step-by-step explanation:
Given that a fitted multiple regression equation is

This is a multiple regression line with dependent variable y and independent variables x1, x2, x3 and x4
The coefficients of independent variables represent the slope.
In other words the coefficients represent the rate of change of y when xi is changed by 1 unit.
Given that x3 and x4 remain unchanged and x1 increases by 2 and x2 by 2 units
Since slope of x1 is 5, we find for one unit change in x1 we can have 5 units change in y
i.e. for 2 units change in x1, we expect 10 units change in Y
Similarly for 2 units change in x2, we expect -2(4) units change in Y
Put together we have
change in y
Since positive 2, there is an increase by 2
A. Increase by 2
