Answer:

Step-by-step explanation:

9. 66 in , 5.5 ft, 1 yd and 8.3 in

10. Not sure about 10 it doesn’t give me all the info to answer

11. 3ft in 1 yard. If there is 3 yards the there is 9 feet. Plus the other 2 feet. So you have 11 ft and there is 12 inches in a foot so you multiply 11ft by 12 inches leaving you with 132 inches in 3 yards and 2 feet

Answer:

First split the fraction.

2t/sqrt(t) + 3/sqrt(2)

2(t^0.5) + 3(t^-0.5)

Add 1 to the power, divide by the new power

2(t^1.5)/1.5 + 3(t^0.5)/0.5

4t^(3/2)/3 + 6t^(1/2) + c

4t×sqrt(t)/3 + 6sqrt(t) + c

Answer:

(a) 1,902,231,808,400

(b) 84

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

${n\choose k}=\frac{n!}{k!\cdot(n-k)!}$

(a)

Compute the number of ways to select 9 applicants from 100 as follows:

${100\choose 9}=\frac{100!}{9!\cdot(100-9)!}$

$=\frac{100!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92\times 91!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92}{9!}\\\\=1902231808400$

(b)

Compute the number of ways to select 6 people from 9 as follows:

${9\choose 6}=\frac{9!}{6!\cdot(9-6)!}$

$=\frac{9!}{6!\times 3!}\\\\=\frac{9\times 8\times 7\times 6!}{6!\times 3!}\\\\=\frac{9\times 8\times 7}{3!}\\\\=84$

(c)

Compute the number of ways to select top 3 candidates from 6 as follows:

${6\choose 3}=\frac{6!}{3!\cdot(6-3)!}$

$=\frac{6!}{3!\times 3!}\\\\=\frac{6\times 5\times 4\times 3!}{3!\times 3!}\\\\=\frac{6\times 5\times 4}{3!}\\\\=20$
