Jim borrows $14,000 for a period of 4 years at 6 % simple interest. Determine the interest due on the loan. [4 marks

Answers

Answer: $ 3,360

Step-by-step explanation:

Given : The principal amount borrowed for loan : $P=\ \$14,000$

Time period : $t=4$

Rate of interest : $r=6\%=0.06$

The formula to calculate the simple interest is given by :-

$S.I.=P* r* t\n\n\Rightatrrow\ S.I.=14000*4*0.06\n\n\Rightatrrow\ S.I.=3360$

Hence, the interest due on the loan = $ 3,360

Answer:

In a quadrilateral ABCD, ∠A = 100°, ∠B = 105° and ∠C = 70°, find ∠D.

Solution:

Here the sum of the four angles

or, ∠A + ∠B + ∠C + ∠D = 360°

We know, ∠A = 100°, ∠B = 105° and ∠C = 70°

or, 100° + 105° + 70° + ∠D = 360°

or, 275° + ∠D = 360°

∠D = 360° - 275°

Therefore, = 85°

Wisconsin Public Radio wants to duplicate a survey conducted in 2011 that found that 68% of adults living in Wisconsin felt that the country was going in the wrong direction. How many people would need to be surveyed for a 90% confidence interval to ensure the margin of error would be less than 3%? Be sure to show all your work and round appropriately

Answers

Answer:

655 people would need to be surveyed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{(\pi(1-\pi))/(n)}$

In which

z is the zscore that has a pvalue of $1 - (\alpha)/(2)$ .

In this question, we have that:

$\pi = 0.68$

The margin of error is:

$M = z\sqrt{(\pi(1-\pi))/(n)}$

90% confidence level

So $\alpha = 0.1$ , z is the value of Z that has a pvalue of $1 - (0.1)/(2) = 0.95$ , so $Z = 1.645$ .

How many people would need to be surveyed for a 90% confidence interval to ensure the margin of error would be less than 3%?

We need to survey n adults.

n is found when M = 0.03. So

$M = z\sqrt{(\pi(1-\pi))/(n)}$

$0.03 = 1.645\sqrt{(0.68*0.32)/(n)}$

$0.03√(n) = 1.645√(0.68*0.32)$

$√(n) = (1.645√(0.68*0.32))/(0.03)$

$(√(n))^(2) = ((1.645√(0.68*0.32))/(0.03))^(2)$

$n = 654.3$

Rounding up

655 people would need to be surveyed.
