A class consists of 23 women and 83 mean. If a student is random selected, what is the probability that the student is a woman?

slavikrds [6]

Answer:

$P(Woman) = \frac{23}{106}$

Step-by-step explanation:

Given

$Women = 23$

$Men = 83$

Required

$P(Woman)$

This is calculated as the number of women divided by the population of the class

i.e.

$P(Woman) = \frac{Women}{Women + Men}$

So, we have:

$P(Woman) = \frac{23}{23+83}$

$P(Woman) = \frac{23}{106}$

Gwyneth begins solving for x in the equation 2 (x minus 4) = 5 (4 minus 2 x) + 4 x. After applying the distributive property and

masya89 [10]

$2(x-4)=5(4-2x)+4x$

$2x-8=20-10x+4x$

$2x+10x-4x=20+8$

$8x=28\\x=\frac{28}{8}$

$x=\frac{28/4}{8/4}=\frac{7}{2} \\x=\frac{7}{2}$

What is the square root of –16? –8i –4i 4i 8i

Ad libitum [116K]

we know that

$i^{2} =-1$

we have

$\sqrt{-16} =\sqrt{(-1)*(16)} =\sqrt{(-1)*(4^{2})}$

substitute the value of $i^{2}=-1$ in the expression above

$\sqrt{(-1)*(4^{2})}=\sqrt{i^{2}*4^{2}} \\ \\= 4i$

therefore

the answer is

$4i$
