What he has left in the bank is here :
(123.17 + 34.68) - 50 = 107.8
He still has $107.8 left in the bank and he has $50 in his pocket.
I hoped I helped!
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 roots of the equation is option D.
Y = -2x + 6
I think this is it
