Answer :
0.53
Step-by-step explanation:
Given the following :
Probability of female = probability of success on a single trial = 0.51
Number of babies = 80
Probability that more than half of the babies are female : p(X >80/2) = P(X > 40)
The problem can be solved using the binomial probability function :
P(X > 40) = [ p(X= 41) + p(X= 42) +.... +p(X= 80)]
In other to save computation time, we can use the binomial probability calculator
Hence ; P(X > 40) = 0.527 = 0.53
Estimating Products
Example 1: 78.
Example 2: 437.
Example 1: 80 x 30.
Example 2: 40 x 700.
Step 1: Round 2 and 3 digit numbers to the nearest ten or hundred. Do not round one-digit numbers.
Step 2: Multiply the non-zero digits.
Step 3: Write the number of zeroes in the rounded numbers on the end of the answer.
Answer:
-6x^3y^-3
Step-by-step explanation:
6x-12x=-6x
5-2=3
y=y
-1-2=-3
-6x^3y^-3
Answer:
f(g(-4)) = 13.
g(f(-4)) = -3.
Step-by-step explanation:
g(-4) = (-4)^2 + 3(-4) - 1
= 3.
so f(g(-4))
= f(3)
= 2(3) + 7
= 13.
f(-4) = 2(-4) + 7
= -1.
so g (f(-4))
= g(-1)
= (-1)^2 - 3 - 1
= -3.
