A bank loans a customer $95,000 for a period of 20 years. The simple interest rate of the loan is 6.5%. What is the amount of si

Ostrovityanka [42]

Answer:

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6.5%/100 = 0.065 per year,

then, solving our equation

I = 95000 × 0.065 × 20 = 123500

I = $ 123,500.00

The simple interest accumulated

on a principal of $ 95,000.00

at a rate of 6.5% per year

for 20 years is $ 123,500.00.

On a number line, suppose point E has a coordinate of 2, and EGequals5. What are the possible coordinates of point G?

Ivan

Answer:

-3, 7

Step-by-step explanation:

EG = 5, so the distance between E and G is five.

G can be 5 units to the right of E:

2 + 5 = 7

G has coordinate 7.

G can be 5 units to the left of E:

2 - 5 = -3

G has coordinate -3.

Answer: -3, 7

A sample of 16 items from population 1 has a sample variance 5.8 and a sample of 21 items from population 2 has a sample varianc

Nady [450]

Answer:

Reject the null hypothesis.

Step-by-step explanation:

n1 = 16

n2 = 21

S.V1 = 5.8

S.V2 = 2.4

$\alpha$ = 0.05

$H_{0}$ = Population Variance 1 ≤ Population Variance 2

$H_{a}$ = Population Variance 1 > Population Variance 2

Test statistic value = 5.8 / 2.4 = 2.417

Degrees of freedom is n - 1

15 and 20

Critical value is $F_{0.05}$ = 2.2

2.417 > 2.2

we reject the null hypothesis as the critical value is greater than the test statistic.
