Answer:

B. $LA=2\pi rh$

Step-by-step explanation:

The lateral area of the right cylinder refers to the curved surface area.

The lateral area of the right cylinder does not include the two circular bases.

The lateral area is given by the formula;

$LA=2\pi rh$

The correct choice is B.

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 X = number of household owns a sports car.

The probability of X is, P (X) = p = 0.07.

Then the random variable X follows a Binomial distribution with n = 3 and p = 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.

Please help me with this!

Answer:

y = x^2 - 4x - 6.

Step-by-step explanation:

The roots are 2 + √10 and 2 - √10, so in factor form we have:

(x - (2 + √10))(x - (2 - √10))

= ( x - 2 - √10)(x - 2 + √10)

= x^2 - 2x + √10x - 2x + 4 - 2√10 - √10x + 2√10 - √100

= x^2 -4x + 4 - 10

= x^2 - 4x - 6.
