21/5.2
because in order to get mean you have to add all the numbers up and divide by the amount you added so 20+28+26+26+30+24+25+26+28+27= 210 divide by 10= 21
in order to get mad you take all the numbers and subtract them from the mean (what ever you get make sure the number is positive) so 21-20=1 28-21=7 and so on then add up the numbers and divide again to get 52 divide that by 10 and you get 5.2
because it is means to mad ratio the answer is 21/5.2
Answer:
the answer is 36
Step-by-step explanation:
Answer:
x = 16
Step-by-step explanation:
16 + 7 = 23
23 - 7 = 16
If Max lands on 4, then Zack can land on 3, 2, 1. The probability that Zack lands on 3, 2, 1 is 1/6 + 1/4 + 1/2 = 11/12.
The combined probability of Max landing on 4 and Zack landing on 3, 2, 1 is:
1/12 * 11/12 = 11/144.
If Max lands on 3, then Zack can land on 2, 1. The probability that Zack lands on 2, 1 is 1/4 + 1/2 = 3/4.
The combined probability of Max landing on 3 and Zack landing on 2, 1 is:
1/6 * 3/4 = 1/8.
If Max lands on 2, then Zack must land on 1. The probability of this is 1/4 * 1/2 = 1/8.
If Max lands on 1, then he cannot get a larger number than Zack.
The overall probability that Max has a larger number than Zack is:
11/144 + 1/8 + 1/8 = 47/144
This is the difference of two squares. If can be simplicied to this
(4x+1)(4x-1)
