Which value of f makes 3f+5=32 a true statement? a. f=6 b. f=8 c. f=9 d. f=12

DIA [1.3K]

We just need to solve the equation in order to find the value.

$3f+5=32$

So we subtract 5 from both sides of the euqation and get

$3f=27$

Now we divide by 3 on both sides and get

$f=9$

So the answer is C.

Hope this helps!

It is commonly assumed that babies are equally likely to come as either a boy or a girl. This is not true. Actually, about 51.3%

Brums [2.3K]

Answer: 0.263169

Step-by-step explanation:

Since for every child there is two outcomes (either a boy or a girl), so it is a binomial distribution.

Let x = Number of boys

Given: probability that a child is a boy: p= 0.513

Binomial distribution formula : $P(X=x)=^nC_xp^x(1-p)^{n-x}$

Now, the probability that both children are boys= $P(X=2)=^2C_2(0.513)^2(1-0.513)^0$

$=(1)(0.513)^2(1)\\\\=0.263169$

The chance both children are boys = 0.263169
