What is the simple interest earned when the principal is $3050, the rate is 6% and 3 years?
Yanka [14]

Answer:

$549

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 3050 × 0.06 × 3 = 549

I = $ 549.00

The simple interest accumulated

on a principal of $ 3,050.00

at a rate of 6% per year

for 3 years is $ 549.00.

In a simple random sample of 1000 Americans, it was found that 61% were satisfied with the service provided by the dealer from w
BlackZzzverrR [31]

Answer:

c. smaller for the sample of Canadians, since the percentage satisfied was smaller than that for the Americans.

Correct we see that the proportion of Canadians is lower than the proportion of Americans since 0.58<0.61. And the reason why is by the percentage.

Step-by-step explanation:

Data given and notation    

X_{A}=610 represent the number of people of America satisfied

X_{C}=580 represent the number of people of Canada satisfied

n_{A}=1000 sample of Americans selected  

n_{C}=1000 sample of Canadians selected  

p_{A}=\frac{610}{1000}=0.61 represent the proportion of American people satisifed

p_{C}=\frac{580}{1000}=0.58 represent the proportion of Canadians satisfied

\hat p represent the pooled estimate of p

Solution to the problem

If we analyze one by one the optiosn we have this:

a. larger for the Canadians because the sample size is smaller.

False, both have the same the same sample size of 1000 and the proportion of Canadians is less than the proportion of Americans.

b. smaller for the sample of Canadians, since the population of Canada is less than half that of the United States. Hence, the sample is a larger proportion of the population.

False, the proportion of Canada is not less than half of the United States since the difference is just 0.61-0.58=0.03

c. smaller for the sample of Canadians, since the percentage satisfied was smaller than that for the Americans.

Correct we see that the proportion of Canadians is lower than the proportion of Americans since 0.58<0.61. And the reason why is by the percentage.

d. larger for the Canadians, since Canadian citizens are more widely dispersed throughout their country than American citizens are in the United States. Hence, Canadians have more variable views.

False the porportion of Canadians 0.58 is NOT higher than the proportion of Americans satisfied 0.61 since 0.58 is not less than 0.61.
