The answer I got was 2,423,000 million square miles. If there is a choice that says that then it’s the answer. If not, I’m probably wrong.

Hope this helps!

The value of a boat is $23,400. It loses 8% of its value every year. Find the approximate monthly percent decrease in value. Rou

Vera_Pavlovna [14]

Answer:

Hello!

To answer your question:

8% of 23,400 is 1872.

23,400- 1872= $21,528 by the end of the first year

1 year=12 months

1872/12= $156- this is how much it is decreased monthly.

156 is 0.67% of 23400, so the monthly percent decrease of 0.67%.

Hope this helps, and hope this is right! :)

A set of laptop prices are normally distributed with a mean of 750 dollars and a standard deviation of 60

s344n2d4d5 [400]

Answer:

0.6

Step-by-step explanation:

Given: Mean= $750

Standard deviation= $60

First, lets find out z-score of the interval between $624 and $768.

z score= $\frac{x-mean}{Standard deviation}$

z score= $\frac{624-750}{60}= \frac{-126}{60}$

∴ z score for $624 is -2.1

Now, finding z score for $768

Z score= $\frac{768-750}{60} = \frac{18}{60}$

∴ z score for $768 is 0.3

As per the z score table, the value for -2.1 is 0.0179 and for 0.3 is 0.6179

Now, subtracting the value to get proportion

$0.6179-0.0179= 0.6$

∴ There are 0.6 proportion of laptops are in the range of $624 and $768
