Answer:
Step-by-step explanation:
Sin(30o) = 0.5 or 1/2
Sin(60o) = sqrt(3)/2
So the statement is false
5+6=? It would be mostly 11
Answer:
0.938
Step-by-step explanation:
From the question :
p = 0.14
Number of children, n = 7
P(x ≤ 2) = P(2) + P(1) + P(0)
Using binomial probability :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
We could also use the binomial probability calculator :
P(x ≤ 2) = 0.3479 + 0.3965 + 0.1936
P(x ≤ 2) = 0.938
The square root of Pi is approximately 1.77245.
The exact answer would be 167.09 so if you round the closest answer is D. $170
