Answer:
√96
Step-by-step explanation:
halve the diameter to set up the pythagorean theorem
2²+b²=10²
4+b²=100
-4 on each side
b²=96
square root each side
b=√96
it could the be further simplified to 4√6
We are given with
n = 1000
p = 0.78
Samples = 10
Condition = at most 7 have one or two social media accounts
We can use combinations to solve the problem
P = ∑10Ci (0.78)^i (1-0.78)^(10-i)/ 1000C10 from i from 0 to 7
Solve for P
31.16665. if you add all those numbers up, then divide it by the total numbers there were, which was six, hints the sides on the dice, then take the number you got after dividing the total by six, and divide that by 2. do this because there are only 3 even numbers on a dice, which is half of the total numbers of sides, and you get 31.16665
