Answer:
4.75
Step-by-step explanation:
<span>95=6x-5(-x-8)
Distribute the -5
95 = 6x + 5x + 40
Subtract 40 from both sides and combine like terms
55 = 11x
Divide both sides by 11
x=5</span>
Segment OX will be the radius.
YZ will be the tangent.
PQ might be the secant.
Hope this helps :)
Answer:
0.9973
Step-by-step explanation:
Given :
Probability of girl, probability of success , 1 - p = 1 - 0.519 = 0.481
1 - p = 0.481
n = 9
Probability that atleast one is girl
Usingbthe binomial probability distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
USing the binomial probability calculator :
p(x ≥ 1) = p(x=1) + p(x=2) + p(x=3) + p(x=4) + p(x=5) + p(x=6) + p(x=7) + p(x=8) + p(x=9)
p(x ≥ 1) = 0.9973 ( from calculator).
