The simplest way is to have 100%
1/2 is half of 100%, so 100/2 = 50%
1/3 is a third of 100%, so 100/3 = 33.33%
1/4 is a fourth of 100%, so 100/4 = 25%
1/5 is a fifth of 100%, so 100/5 = 20%
To turn a fraction into a percent, you simplify it
So for example...
4/6 = 2/3 = 66.66%
12/36 = 6/18 = 3/9 = 1/3 = 33.33%
Answer:
Option D is correct.
Step-by-step explanation:
We have been given the rate is raised by $45
Since, if we increased mean by 45 there will be no change in number of observations and in sum because there is symmetry in the sum of observations.
So, mean will be increased by $45
And standard deviation will remain same because it means how far the term is from the mean.
Therefore, option D is correct.
Answer:
18
Step-by-step explanation:
25 + 47 = 72
72 ÷ 4 = 18
(3,2) is the center and 4 is the radius (incase you need that too)
Answer:
x=10
Step-by-step explanation:
110 and 8x + 30 are vertical angles, which means they are equal
110 = 8x+30
Subtract 30 from each side
110-30 = 8x+30 -30
80 = 8x
Divide each side by 8
80/8 = 8x/8
10 =x
