In a 2-way frequency table, you take the row entry and divide it by its row total to get a decimal.
For your example:
It starts out like this:
sunny snowy
Male: 17 11
Female: 15 16
Add the rows up.
sunny snowy total
Male: 17 11 28
Female: 15 16 31
Then divide the number the by the total:
sunny snowy total
Male: 17/28 11/28 28
Female: 15/31 16/31 31
Yours says to round to the 1000th place, so it ends up like:
sunny snowy
Male: .607 .393
Female: .484 .515
Hope that helps!!
Get into ax²+bx+c=0 form
subsitute u=x⁴
x⁸-3x⁴+2=0
(x⁴)²-3(x⁴)+2=0
u²-3u+2=0
factor
(u-2)(u-1)=0
set to zero
u-2=0
u=2
u-1=0
u=1
wait, u=x⁴
2=x⁴
![\sqrt[4]{2}=x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%7D%3Dx)
1=x⁴
+/-1=x
the subsitution is u=x⁴
and the possible values for x are -1,
![\sqrt[4]{2}=x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%7D%3Dx)
, and 1
Answer:1231
Step-by-step explanation:
1,231
The sale price of the coats is 160% of the purchase price of the coats.
<u>Step-by-step explanation:</u>
The owner buys the coats at a purchase price= $60
He sells the coats for a selling price= $96
Now, the question is:
The selling price $96 is what percentage of the purchase price $60
<u>step 1</u>: 96= x% of 60
<u>step 2</u>: 96= (x/100)*60
<u>step 3</u>: 96= 6x/10
<u>step 4</u>: 960/6 = x
<u>step 5</u>: x = 160%
Answer:
