Answer:
<h2>
Option B)</h2>
Step-by-step explanation:
ok so is 9% so 5000+450x-500
5000+(450)(25)−500
=15750
and and 8% 800 so 10000+800x-300
10000+(800)(25)−300
=29700
The closeness of the scores to the mean value is reflected through the values of the standard deviation. The smaller the value of standard deviation, the closer are the individual values to the mean. Therefore, since Mrs. Rijo's class has the smallest value for the standard deviation, her class has the closest individual score to the mean. The answer is the fourth choice.

Answer:
3 ÷ 1/3 = 9
Step-by-step explanation:
= 3 ÷ 1/3
= 3/3 (3/1) ÷ 1/3
= 9/3 × 3/1
= 9/1
= 9
1. We assume, that the number 40 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 40, so we can write it down as 100%=40.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=40
2) x%=21
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=40/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 21 is what percent of 40
100%/x%=40/21
(100/x)*x=(40/21)*x - we multiply both sides of the equation by x
100=1.90476190476*x - we divide both sides of the equation by (1.90476190476) to get x
100/1.90476190476=x
52.5=x
x=52.5
now we have:
21 is 52.5% of 40
