Hi ;-)

2x ⇒ dogs

5x ⇒ cats

2x + 5x = 14

7x = 14  / : 7

x = 2

2 · 2 = <u>4 dogs</u>

5 · 2 = <u>10 cats</u>

LekaFEV [45]

Answer:

The choice C.

12 \frac{1}{2}

Step-by-step explanation:

( \frac{4}{5}  -  \frac{1}{3} ) \times  {5}^{2}   +  \frac{5}{6}  \\  \\ ( \frac{12}{15}  -  \frac{5}{15} ) \times 25 +  \frac{5}{6}  \\  \\ ( \frac{12 - 5}{15} ) \times 25 +  \frac{5}{6}  \\  \\ ( \frac{7}{15} ) \times 25 +  \frac{5}{6}  \\  \\  \frac{35}{3}  +  \frac{5}{6}  \\  \\  \frac{70}{6}  +  \frac{5}{6}  =  \frac{75}{6}  \\  \\  =  \frac{25}{2}  = 12 \frac{1}{2}

Rudiy27

Answer:

b. 42 people

Step-by-step explanation:

For each foreigner living in the U.S., there are only two possible outcomes. Either they are naturalized citizens, or they are not. The probability of a foreigner living in the U.S. not being a naturalized citizen is independent from other foreigners living in the U.S. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

"approximately 60% of foreign-born people who live in the U.S. are not naturalized citizens"

This means that p = 0.6

70 foreign-born people who live in the U.S

This means that n = 70

How many people would you expect to get that are not naturalized citizens?

E(X) = np = 70*0.6 = 42

So the correct answer is:

b. 42 people
