Marizza181 [45]

Answer:

The answer is 8.88; You look at the number that comes after the second number (the second place after the decimal) and if that number is 5 or above then you round the second number up. (Sorry if it doesn't make sense, but that's the best I can explain it).

Which number belongs to the solution set of the equation below?
ollegr [7]
The correct answer would be: C. 44
Explanation: If you're trying to find out x's value, you have to do the inverse operation which means if it's subtraction, you add. So to find x's value, you'd add 36 + 8 = x. And 36 + 8 = 44. So therefore, x = 44. That means the answer is C.

rjkz [21]

a) n (No. of peoples) = 50

r (No. of prizes) = 3

p(n,r) = p (50,3)

\begin{gathered} P(n,r)=\frac{n!}{(n-r)!} \\ P(50,3)=\frac{50!}{(50-3)!} \\ =117600 \end{gathered}

b) n(No. of players)=14

r (No. of players for Batting)=9

\begin{gathered} P(14,9)=\frac{14!}{(14-9)!} \\ =726485760 \end{gathered}

c)n(Total applicants)=30

r(tester positions)=4

\begin{gathered} P(30,4)=\frac{30!}{(30-4)!} \\ \text{              =}\frac{30!}{26!} \\ \text{              =657720} \end{gathered}
