What is the percent of decrease from 110 to 77

Charra [1.4K]

If you want to easily find the solution you can use your calculator.
Just divide 77 by 110 and see the result.
77/110 = 0.7 = 7/10 = 70/100 = 70%
100% - 70% = 30%

Explanation
110*x=77
x=77/110, but the answer is not a percent
So 77/110 = ?/100 => ?=77*100/110=70 => 70%
But since 70% does not represent a percentage decreasement, we need to subtract it from the 100%
100% - 70% = 30%

Use this information for exercises 11-14.parents are older than their children.the ratio of a parent´sage to a child´s age chang

Shtirlitz [24]

I think 11 is yes, if the parent is 40 and the child is 20. (and they had kids when they were young) 12 is yes, if the parent is 30 and the child is 10. 13 is yes, if the parent is 60 and the child is 40. unlikely though, but who cares. 14 is no, the parent would have been really young when they gave birth to the child. like 10.

pychu [463]

Answer:

Standard error of the mean parameter the average content of colognes

S.E = 0.02 ounces

Step-by-step explanation:

Explanation:-

Size of random sample 'n' = 121 bottles

mean of the sample $x^{-} = 4$ ounces

Standard deviation of Population

σ = 0.22

Standard error of the mean parameter the average content of colognes

$S.E = \frac{S.D}{\sqrt{n} }$

$S.E = \frac{S.D}{\sqrt{n} } = \frac{0.22}{\sqrt{121} }$

S.E = 0.02

Final answer:-

Standard error of the mean parameter the average content of colognes

S.E = 0.02 ounces
