Answer: B and D or 2 and 4

Step-by-step explanation:

1. is NOT correct as the mean absolute deviation is 22 not 15

2. is CORRECT the mean absolute deviation is 18

the mean of A is 216

the mean of B is 215

one tenth of 215/216 is 21.5/21.6 that is about the absolute mean deviation which 18/22

Which makes one tenth the wrong answer.

This is also makes one twentieth the correct answer

Use the info given to find the new price: original price: $24 and discount rate: 11%. What is the new price????
ELEN [110]
So I think you have to find 11% of 24 and that is 11/100 x 24 = 2.64$. Then you reduce it to the real price 24-2.64= 21.36$ (the new prize). I might be completly wrong but I hope this helps

andriy [413]

Answer:

L=70

Step-by-step explanation:

L=2w+6

204=2L+2W

204=2w+2(2w+6)

204=2w+4w+12

192=6w

w=32

L=2(32)+6

L=70

Use this picture to solve for X
Zepler [3.9K]

Answer:

x=2

Step-by-step explanation:

i would set up a system of equation using the pythagorean theorem:

1^2+x^2=z^2

4^2+x^2=y^2

Add up these equations to get:

17+2x^2=y^2+z^2

But notice that

y^2+z^2=5^2

So you can substitute

17+2x^2=25

2x^2=8

x^2=4

x=2
