Her whole wall is 1=6/6 hence what's not white is 1-2/6=4/6=2/3.
2/3 of her wall is green.
Answer:
Yes, multiplying by 3/10 is the same as multiplying by 30%
Step-by-step explanation:
Lets compare the numbers.
I will change them both to decimals.
3/10 = .3
30 %
Percent means out of 100
30 % = 30/100 = .3
They are the same number.
So when we multiply, we are multiplying by the same number.
Answer: 0.04 is exactly 10 times as much as 0.004. If we multiply 0.004 by 10, we will get 0.04 as an answer. In other words, we can say that 0.004 is exactly 1/10th of 0.04. It means that if we divide 0.04 by 10, we will get 0.004 as an answer.
First we find the mean (average)
(17 + 18 + 19 + 20 + 21) / 5 = 95/5 = 19
now subtract 19 from all values...then square it
17 - 19 = -2...-2^2 = 4
18 - 19 = -1...-1^2 = 1
19 - 19 = 0...0^2 = 0
20 - 19 = 1....1^2 = 1
21 - 19 = 2...2^2 = 4
now take the mean (average) of those
(4 + 1 + 0 + 1 + 4) / 5 = 10/5 = 2 <== this is ur variance
standard deviation is the square root of the variance...
sq rt 2 = 1.414
By three times the number variable
