13. A sales lady is paid commission at the rate of 3% on all goods she sells. During
one month, she sold 12 television at sh. 15,500 each, 8 D.V.D player at sh. 5,650
and 4 refrigerators at sh. 21,700 each. Calculate the total commission she earned
in that month.
​

Answers

Answer: Sh. 9540

Step-by-step explanation:

First, we have to calculate the cost of the total things sold. This'll be:

12 television at sh. 15,500 each = sh. 186000

8 D.V.D player at sh. 5,650 = sh. 45200

4 refrigerators at sh. 21,700 each = sh. 86800

Total cost = sh. 186000 + sh. 45200 + sh. 86800 = sh. 318000

Since the sales lady is paid commission at the rate of 3% on all goods she sells, the total commission that she earned

in that month will be:

= 3% × sh. 318000

= 0.03 × sh. 318000

= Sh. 9540

A credit card company advertises an APR of 17.2%, compounded daily. What is the effective interest rate

Answers

Answer:

18.76%

Step-by-step explanation:

effective interest rate = ( 1 + periodic interest rate)^m - 1

m = number of compounding = 365

Periodic interest rate = APR / number of compounding = 17.2 / 365 = 0.0471% = 0.000471

(1 + 0.000471) ^365 - 1 = 18.76%

What is the value of s? Uhm uh why is this so difficult.

Answers

Answer:

s = 47

Step-by-step explanation:

The measure of the exterior angle of a triangle is equal to the sum of the opposite interior angles

s+45 = s+6  + s-8

Combine like terms

s+45 = 2s-2

Subtract s from each side

s+45-s =2s-2-s

45 =s-2

Add 2 to each side

45+2 = s-2+2

47 =s

Answer:

a = 30°

b = 11°

Step-by-step explanation:

JK = 360 - 110 - 130 - 54 = 66°

Inscribed angles = 1/2 their arc

∠K = 1/2(130 + 54) = 92°

∠J = 1/2(110 + 130) = 120°

∠M = 1/2(66 + 110) = 88°

8b = 88°

b = 11°

Devon’s tennis coach says that 72% of Devon’s serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 42 of them are good. To determine if these data provide convincing evidence that the proportion of Devon’s serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon’s hypotheses are: H0: p = 72% and Ha: p > 72%, where p = the true proportion of Devon’s serves that are good. Based on the results of the simulation, the estimated P-value is 0.06. Using Alpha= 0.10, what conclusion should Devon reach?
Group of answer choices

Because the P-value of 0.06 < Alpha, Devon should reject H0. There is convincing evidence that the proportion of serves that are good is greater than 72%.

Because the P-value of 0.06 < Alpha, Devon should fail to reject Ha. There is convincing evidence that the proportion of serves that are good is greater than 72%.

Because the P-value of 0.06 < Alpha, Devon should fail to reject Ha. There is not convincing evidence that the proportion of serves that are good is greater than 72%.

Because the P-value of 0.06 < Alpha, Devon should reject H0. There is not convincing evidence that the proportion of serves that are good is greater than 72%.

Answers

Answer:

Because the P-value of 0.06 < a, Devon should reject H0. There is convincing evidence that the proportion of serves that are good is greater than 72%.

Step-by-step explanation:

Right on edge 2022

The conclusion is (a) Because the P-value of 0.06 < Alpha, Devon should reject H0. There is convincing evidence that the proportion of serves that are good is greater than 72%.

How to determine the conclusion?

The given parameters are:

Null hypothesis H0: p = 72% Alternate hypothesis Ha: p > 72%,p value = 0.06α = 0.10

By comparison, the p-value is less than the alpha value

i.e. 0.06 <0.10

When the p-value is less than the alpha value, the null hypothesis is rejected.

Hence, the conclusion is (a)
