<h3><u>Question:</u><u>-</u></h3>

Profit % = Profit × 100/cost price

16. A large-sample 95 percent confidence interval for the proportion of credit
borishaifa [10]

Answer:

(B) 0.057

Step-by-step explanation:

The 95% confidence interval is (0.028, 0.086). The formula for the confidence interval is μ ± e where μ is the mean and e is the margin of error.

Therefore the confidence interval is (μ - e , μ + e).

That is μ - e = 0.028 and μ + e = 0.086

To get the point estimate which is the mean, we sum the two proportions and divide it by two.

Therefore point estimate (μ) = (0.028 + 0.086) / 2 = 0.057

Jacob went on a fishing trip. This year he caught 30 fish, which is six more than twice the number he caught last year. How many
NARA [144]

Answer:

12 fish

Step-by-step explanation:

You need to work this problem backwards. If he caught 30 fish, which was six more than twice the number he caught last year, you would start by subtracting six, leaving you with 24. Then you'd have to divide by 2, because it was twice plus six as many fish, which would give you 12 fish.

\frac{30-6}{2} = x

\frac{24}{2} = x

12 = x
