4 0

The mean absolute deviation is the mean of the absolute values of the differences of the numbers from their mean. It is convenient to let a spreadsheet or calculator do the tedious math. Here it is by hand:

Total of given values: 135

Mean of given values: 135/6 = 22.5

Deviations of given values from the mean:

... {2.5, 1.5, 2.5, 0.5, -2.5, -4.5}

Absolute values of deviations from the mean:

... {2.5, 1.5, 2.5, 0.5, 2.5, 4.5}

Total of those: 14

Mean absolute deviation: 14/6 = 2 1/3.

By what percent will the fraction increase if its numerator is increased by 60% and denominator is decreased by 20% ?
seropon [69]

Answer:

100%

Step-by-step explanation:

Start with x.

x = x/1

Increase the numerator by 60% to 1.6x.

Decrease the numerator by 20% to 0.8.

The new fraction is

1.6x/0.8

Do the division.

1.6x/0.8 = 2x

The fraction increased from x to 2x. It became double of what it was. From x to 2x, the increase is x. Since x was the original number x is 100%.

The increase is 100%.

Igoryamba
I think you mean write in word format so yea

11.09
"Eleven and 9 hundredths"
To convert decimals to fractions first put the decimal over 1, multiply by ten for every number after the decimal point and simplify.

(11.09/1)(10)(10) *Because there are 2 numbers after the . 0 and 9*

1109/100
This will be the most simplified you can get it!
As a mixed number:
11 9/100

Follow these steps for the rest!

21.06
"twenty one and six thousandths"
1053/50
21 3/50

0.06
"six thousandths" or
"zero and six thousandths"
3/50

0.50
"fifty thousandths" or "five tenths" since 0.50=0.5
1/2


6.15
"six and fifteen thousandths"
123/20
6 3/20

7.41
"seven and fourty one thousandths"
741/100
7 41/100

Find the sequence 3n-1
aivan3 [116]

a(1) = 3(1)-1 = 3-1 = 2

a(2) = 3(2)-1 = 6-1 = 5

a(3) = 3(3)-1 = 9-1 = 8

So, the sequence would be 2,5,8,11....
