Answer:

Choice D is correct answer.

Step-by-step explanation:

We have given a list of values.

2,63,88,10,72,99,38,19

We have to find mean and value of n.

n is the total number of values.

Hence, n = 8

Formula to find mean is :

Mean = sum of values / number of values

Sum of values = 2+63+88+10+72+99+38+19 = 391

Number of values = 8

Mean = 391/8

Mean = 48.875

Mean of the following sample is 48.875

How do you do the slope on a graph

Semmy [17]

I can't be entirely sure what you want to "do" about the slope,
but here is how to FIND it if you have the line on the graph:

-- You pick two points on the graph line.

-- Find the difference in 'y' between the two points.

-- Find the difference in 'x' between the two points.

-- The slope of the line between the two points is

(the difference in 'y')
divided by
(the difference in 'x') .

-- If the line on the graph is a straight line, then
the slope is the same everywhere on it.

<u>Answer:</u>

$593.26

<u>Step-by-step explanation:</u>

We know that the price of the laptop is $2500 and each year its resale value decreases by 25%. It means that 100 - 25 = 75% of the value is retained every year for the resale.

So, the resale value for 1st year = $\frac{75}{100} *2500 =$ $1875
