=x^4+3x^3-7x²-15x+18
Answer A
The probability of a baby being a boy is 0.514.
Nine baby births are selected and we have to find the probability that at last one of them is a girl.
P(At least one out of 9 is baby girl) = 1 - P(No baby girl)
= 1 - P(All 9 are baby boy)
= 1 - (0.514)^9
= 1 - 0.0025
= 0.9975
The probability that at least one out of 9 selected births is baby girl is 0.9975
Answer:
its 31 when you round to 2 decimal points.
The cost to buy 10 notebooks and 16 desktop computers is $5550
Cost of notebook computers = $275
Cost of desktop computers = $175 each
The cost to buy 10 notebooks and 16 desktop computers will be:
= 275(10) + 175(16)
= 2750 + 2800
= $5550
The cost to buy n notebooks and d desktop computers will be:
= 275(n) + 175(d)
= 275n + 175d
