Answer:

x = 8

y = 1

Step-by-step explanation:

Slope = difference in y values / corresponding difference in x values

Slope = (9 - 5) / (x - 10) = -2

-2x + 20 = 4

x = -16 / -2 = 8 (answer)

Question 4

(y - 6) /(1 - 2) = 5

y - 6 = -5

y = 1 (answer).

Based on a survey, assume that 43% of consumers are comfortable having drones deliver their purchases. Suppose that we want to

lutik1710 [3]

Answer:

The probability that exactly three of them are comfortable with delivery by drones is 0.2583.

Step-by-step explanation:

Let X = number of consumers comfortable having drones deliver their purchases.

The probability of the random variable X is, P (X) = p = 0.43.

Then q is, q = 1 - p

A sample of n = 5 consumers are selected.

The random variable X follows a Binomial distribution with parameters n and p.

The pmf of X is:

$P(X=x)={n\choose x}p^{x}(1-p)^{n-x};\ x=0,1,2,3...$

Compute the value of P (X = 3) as follows:

$P(X=3)={5\choose 3}0.43^{3}(1-0.43)^{5-3}\\=10\times 0.079507\times 0.3249\\=0.258318\\\approx0.2583$

Thus, the probability that exactly three of them are comfortable with delivery by drones is 0.2583.

Olegator [25]

Answer:

36 students got an'A' grade in the quiz.

Step-by-step explanation:

Given:

Total number of students taking the quiz = 132

Fraction of students getting an 'A' grade = $\frac{3}{11}$

To find the number of students getting an 'A' grade.

Solution:

In order to find the number of students who got an 'A' grade in the quiz, we will find the fractional part who got an 'A' of the total students taking the quiz.

The fraction of students getting an 'A' is = $\frac{3}{11}$

Thus, total number of student getting an 'A' is :

⇒ $\frac{3}{11}$ of $132$

⇒ $\frac{3}{11}\times 132$

⇒ $\frac{396}{11}$

⇒ 36 (Answer)
