treadmill at the local gym is 28 minutes with a
standard deviation of 8. If Kurt's z-score is
1.75, how much time did he spent on the
treadmill?

With a z score of 1.75, mean of 28 and standard deviation of 8

1.75=(Xi-28)/8

14=(Xi-28)

42 = Xi

Kurt was on the treadmill for 42 minutes

A store purchased a plasma screen TV for $770 and marked it up 150%. During a sale, the store marked it down 20%. What was the discount price on the plasma screen TV?​

Answers

Answer:

1540

Step-by-step explanation:

First find the new price after the markup

The markup is

770 * 150%

770 * 1.5

1155

Add this to the original price

770 + 1155

1925

Now find the discount

1925*20%

1925*.20

385

Subtract this amount from the 1925

1925-385

1540

The final price is 1540

Answer:

Solution given:

cost price [c.p] of TV =$770

MP=c.p+ 150% of c.p=$770+150/100×770=$1925

discount [D]=20%

now

discount amount=D% of MP=20/100×1925=$385 is your answer.

$385 was the discount price on the plasma screen TV.

Evaluate.0.2 power of 4 =

Answers

Answer:

0.0016

Step-by-step explanation:

The expression 0.2 by the power of 4  when evaluated has a value of 0.0016

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

0.2 by the power of 4

Express as an equation

So, we have

0.2 by the power of 4 = 0.2⁴

When expanded, we have

0.2 by the power of 4 = 0.2 * 0.2 * 0.2 * 0.2

Evaluate the products

This gives

0.2 by the power of 4 = 0.0016

Hence, the solution is 0.0016

Apple juice and cranberry juice have been mixed in the ratio of 4:5. If the price of apple juice is 45 cents per pint and the price of cranberry juice is $0.8 per pint, what should the price of one pint of the mixture be?

Answers

Answer:

$0.24

Step-by-step explanation:

The computation of the price of the one pint of the mixture is shown below:

Since the ratio of apple juice and cranberry juice is 4:5

And, the price of apple juice is 45 cents i.e. = 0.45 × 4 ÷  9 = 0.2

Also the price of cranberry juice is $0.8 = $0.08 × 5 ÷ 9 = 0.04

SO, the price of one pint of the mixture is

= 0.2 + 0.04

= $0.24
