Answer:
B . 4x^2 + 14x
Step-by-step explanation:
2(2x^2+4x-8) + 2(3x+8)
=4x^2 +8x-16+6x+16
=4x^2+14 (ans)
Answer:
17
Step-by-step explanation:
85 divided by 5 in distributive property
85 can be break into 80 and 5
80+5 is 85
Now we divide each term by 5
Denominator 5 is distributed 5 inside the numerator
17 is the final answer
This is a right triangle (you can confirm by using Pythagorean Theorem: 15² + 36² = 39²)
A =
A =
= 15 * 18
= 270
Answer: 270 cm²
The expected number of female children in a family with three children is 1.5.
The correct option is B.
We have to determine
What is the expected number of female children in a family with three children?
<h3>Probability;</h3>
Probability is defined as the sum of all observations and the number of observations.
The expected value of female children= Probability of female children x Total number of children.
A child can be male or female, so there are 2 combinations, the favorable outcome is female.
The probability of female children = 1/2.
Therefore,
The expected number of female children in a family with three children is;
Hence, The expected number of female children in a family with three children is 1.5.
