Answer:

Probability that a  house has a hot tub given that it has a pool is 55%.

Step-by-step explanation:

We are given that in New York State, 38% of the houses have a pool and 21% of the houses have both a pool and a hot tub.

Let the probability that houses have a pool = P(A) = 0.38

Also, let B = event that houses have a hot tub

Probability that houses have both a pool and a hot tub = P(A \bigcap B) = 0.21

Now, the conditional probability that a  house has a hot tub given that it has a pool is given by =  P(B / A)

<u>As we know that</u>;   P(B / A)  =  \frac{P(A \bigcap B)}{P(A) }

                                              =  \frac{0.21}{0.38}  

                                              =  0.553 ≈ 55%

Hence, the probability that a  house has a hot tub given that it has a pool is 55%.

If c(x)=4x-2 and d(x)=x^2+5 , what is (c o d) (x)
Nookie1986 [14]

Answer:

4x² + 18

Step-by-step explanation:

note that (c ○ d )(x) = c(d(x))

To evaluate substitute x = d(x) into c(x), that is

c(d(x))

= c(x² + 5)

= 4(x² + 5) - 2

= 4x² + 20 - 2

= 4x² + 18

Look at this inequality.<br><br><br>−0.2x+1.2&lt;1.1
WINSTONCH [101]

Answer:

x > 0.5

Step-by-step explanation:

Given

- 0.2x + 1.2 < 1.1 ( subtract 1.2 from both sides )

- 0.2x < - 0.1

Divide both sides by - 0.2, reversing the symbol as a result of dividing by a negative quantity.

x > 0.5
