Answer:
275
Step-by-step explanation:
Given that a survey of 391 children given at a local elementary school showed that 150 like chocolate ice cream, 225 like pistachio ice cream, and 116 do not like chocolate or pistachio ice cream.
Total = 391
cholocate ice cream =150
pistchio ice cream = 225
Neither -=116
If we partition universal set into disjoint sets exhaustive
we have A-B, B-A, AB, and (AUB)'
Total = 391
Let n(AB) i.e. likes both be x
Then we have n(A-B) = 150-x and n(B-A) = 225-x
Totalling
no of children who like atleast one kind of ice cream = n(U)-n(AUB)"
= 391-116
= 275
For this case we apply the Pythagorean theorem, clearing the height we have:
According to the data we have:
Substituting:
We round and we have the height is
