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.

Convert the following equation into slope intercept form. 3x + 21y = 21 Stars
RideAnS [48]

Answer:

y = -(1/7)x + 1

Step-by-step explanation:

3x + 21y = 21 \\ 21y = 21 - 3x \\ y =  \frac{21 - 3x}{21}  \\ y = 1 -  \frac{1}{7} x \\ y =  -  \frac{1}{7} x + 1

I Need Help On This
disa [49]

Answer:

The first blank: not equal

The 2nd blank: not right triangle (it's acute triangle)

The 3rd blank: equal

The 4th blank: it's right triangle

Step-by-step explanation:

4^2 = 3^2 + 3^2

<=> 16 = 9 + 9

<=> 16 = 18 ( nonsense)

so triangle LKJ is not right triangle

5^2 = 4^2 + 3^2

<=> 25 = 16 + 9

<=> 25 = 25 ( make sense)

so triangle ABC is right triangle

Done!! :))
