IQR is the Q3 - Q1
Put the data in order.....
6, 7, 11, 13, 14, 15, 15, 19, 21
^ ^ ^
9(Q1) 14(Q2) 17(Q3)
17 (Q3) - 9 (Q1) = 8 (IQR)
So the answer to your question is the first option, 8.
Hope this helps! :D
Answer:
The answer is 37.44
Step-by-step explanation:
Step 1: Divide 52 by 100
In this case, the number that we are "comparing" to 100 is 52, so we must first normalize the number by dividing it by 100. The operation we have to solve is this:
52
100
=
52
÷
100
=
0.52
Step 2: Multiply 0.52 by 72 to get the solution
Now that we have our normalized number, 0.52, we just have to multiply it by 72 to get our final answer. The forumla for this is obviously quite simple:
0.52
×
72
=
37.44
Answer:
Step-by-step explanation:
If Quan had 15 and Kaden had 3 times as much, then Kaden had 15(3) = 45. If he spent 10 then he had 35 left. The amount of money Quan had after his mom gave him some was 4/5 the amount of Kaden's 35 (let x = the amount of money Quan has after his mom gives him some):
35 divides by the 5 in the denominator 7 times, and 7 times 4 is 28. That's how you get your 28 in part a.
For part b., he started with 15 and ended with 28, so his mom gave him 28-15=13. That's how you get the 13.
