Suppose that a recent poll of American households about car ownership found that for households with a car, 39% owned a sedan, 3
Rama09 [41]

Answer:

The probability that of the 3 households randomly selected at least 1 owns a sports car is 0.1956.

Step-by-step explanation:

Let <em>X</em> = number of household owns a sports car.

The probability of <em>X</em> is, P (X) = p = 0.07.

Then the random variable <em>X</em> follows a Binomial distribution with <em>n</em> = 3 and <em>p</em> = 0.07.

The probability function of a binomial distribution is:

P(X=x) = {n\choose x}p^{x}[1-p]^{n-x}\\

Compute the probability that of the 3 households randomly selected at least 1 owns a sports car:

P(X\geq 1)=1-P(X

Thus, the probability that of the 3 households randomly selected at least 1 owns a sports car is 0.1956.

Lelu [443]

We are given coordinates of the school located at a point (9,-1).

Library is located 5 blocks south and 4 blocks west .

According to coordinate axes, south is downward and west is on left side.

So, we need to move 5 units down of 9.

<em>5 units down of 9 would be 9-5 = 4.</em>

And then <em>4 blocks west that mean -1 -4 = -5.</em>

<h3>Therefore, coordinate of the library is located at the point (4,-5).</h3>

5/6 = x-4/x

cross multiply

5x = 6x - 24

24= x
