A bookkeeper bought 2,000 exercise book distributed 200 books to the student from poor economic background as donation .he sold
Andrews [41]

Books left=2000-200=1800

ATQ

\\ \sf\longmapsto 1800x+10=0.08x

\\ \sf\longmapsto 1800x-0.08x=-10

\\ \sf\longmapsto x(1800-0.08)=-10

\\ \sf\longmapsto x(1799.92)=-10

\\ \sf\longmapsto x=|\dfrac{10}{1799.92}|

\\ \sf\longmapsto x=0.005

Now

\\ \sf\longmapsto CP=0.005(2000)=10

The mean absolute deviation of the scuba diver’s depth over the entire 25 min is 2.4 meters

<h3>What is mean absolute deviation?</h3>

It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.

We have depths of the scuba diver, in meters

{−9, −18, −16, −13, −14}

We know the formula for the mean absolute deviation:

\rm MAD = \dfrac{\sum |x-X|}{n}

Here n is total number of observation

x is the elements in the data set

X is the mean of the data.

n = 5

x = -70/5 = -14

∑|x-X| = 12

MAD = 12/5 = 2.4 meters

Thus, the mean absolute deviation of the scuba diver’s depth over the entire 25 min is 2.4 meters.

Solve this system algebraically.
seraphim [82]
From y-2x+3=0 we have y=2x-3
So we can replace y by 2x-3 in the equation: 9x+2y=5
And we have 9x+2(2x-3)=5
Or 9x+4x-6=5
and 13x=5+6
Or x=11/13, then y=2x-3= 2. 11/13-3=22/13-3= -17/13

So we have the answer <span>{(11/13, -17/13)}</span>
