Answer:

A. 1.15 x $10^{2}$

Step-by-step explanation:

We can find out how many times larger is the diameter of the sun than the diameter of Venus by dividing the diameter of the sun by the diameter of Venus, and so we get...

1391000 / 12100 ≅ 115

115 is equal to 1.15 x $10^{2}$ , therefore the right answer is A.

At Johnson Elementary School, there are 24 educational staff personnel consisting of the following: 7 male teachers, 16 female t

elena-s [515]

a. To solve this, we should make a combination

$\begin{gathered} nCr=\frac{n!}{r!(n-r)!} \\ 24P5=\frac{24!}{5!(24-5)!}=42504 \end{gathered}$

5 person committee can be chosen in 5100480 different ways

b. To find this probability (A), we should use the answer of the last question as the total cases, and the favourable cases will be the shown combinations

$P(A)=\frac{7C3\cdot17C2}{42504}$

Calculate the combinations

$\begin{gathered} 7C3=\frac{7!}{3!(7-3)!}=35 \\ 17C2=\frac{17!}{2!(17-2)!}=136 \\ P(A)=\frac{35\cdot136}{42504}=\frac{4760}{42504}=0.1120 \end{gathered}$
