Answer:

3.Tan(45)=n/2

1=n/2

n=2

Cos(45)=2/m

1/√2=2/m

m=2√2

5.Sin(60)=x/14

√3/2=x/14

14√3/2=x

x=7√3

Cos(60)=y/14

1/2=y/14

y=7

Answer:

The probability is $P(14 < X < 20 ) = 0.5354$

Step-by-step explanation:

From the question we are told that

The proportion that live with their parents is $\r p = 0.142$

The sample size is n = 125

Given that there are two possible outcomes and that this outcomes are independent of each other then we can say the Recent census data follows a Binomial distribution

i.e

$X \ \~ \ B( \mu , \sigma )$
