What will be the value of median of a moderately asymmetrical distribution? If the mean and mode are 30 and 24 respectively.

sineoko [7]

The mean, the median and the mode are measures of central tendency, and they are related in some many ways, depending on the type of distribution.

The median of the moderately asymmetrical distribution is 26

The given parameters are:

$Mean = 30$

$Mode = 24$

For a moderately asymmetrical distribution, the mean, median and mode are related by the following equation:

$Mode = 3 * Median - 2 * Mean$

Substitute known values

$30= 3 * Median - 2 * 24$

$30= 3 * Median - 48$

Collect like terms

$3 * Median =30+ 48$

$3 * Median =78$

Divide both sides by 3

$Median =26$

Ava borrowed some money from her friend in order to help buy a new video game system. Ava agreed to pay back her friend $2 per w

nydimaria [60]

We know that Ava is paying $2 dollars per week so if L is the money that she owes and t is the number of weeks, and I is the initial debt so we can write an equation like:

$L=I-2t$

Now we can replace the info we have to find the value of I so:

$10=I-2(5)$

and we solve for I

$\begin{gathered} I=10+10 \\ I=20 \end{gathered}$

So the final equation will be:

$L=20-2t$

$(-) \times (-) = +\\\\(+) \times (+) = +\\\\(-) \times (+) = -$

$a) \ \ -4(-4+3)+2^2 = -4(-1)+4 = (-4 \times -1) + 4 = 4 + 4 = 8\\\\b) \ \ - 3 - 3 - 3 - (-3) = ( -3 - 3) -3 - (-3) = -6 -3 - (-3)\\ \ \ \ \ \ \ = -9 --3 =-9+3 = -6\\\\c) \ \ -17 + 2 (-2)(-2) = -17 + 2(-2 \times -2) = -17 + 2 ( 4) = -17 + 8 = -9\\\\d) \ \ (2 + (-3)(5))(3 + 2(-6)) = (2 + (-3 \times 5))(3 + (2 \times -6)) \\ = (2 + (-15))(3 + (-12)) = (2 -15)(3 -12)\\ = (-13)(-9) = (-13) \times (-9) \\= 13 \times 9 = 117$

Please Help! I've been waiting for a while!!

Elanso [62]

First distribute
a(b+c)=ab+ac so
2(x+3)=2x+6
-3(2-2x)=-6+6x
5x+3=2x+6-6+6x
add like terms
5x+3=2x+6x+6-6
5x+3=8x+0
subtract 5x from both sides
3=3x
divide both sides by 3
1=x

there are 1 solutions
