Range: set of y values

Function: no two x values are the same

Line 1:

Domain: {3, 4, 5}

Range: {1, 2, 3, 4}

Function: no since there are two points with x-coordinate 3

Line 2:

Domain: {-1, -2, 1, 2}

Range: {1, 3}

Function: yes since all x-coordinates are different

Line 3:

Domain: {-2, -1, 0, 1, 2}

Range: {0, 1, 4}

Function: yes since all x-coordinates are different

➷ To find the median, you need to order your numbers first.

14, 16, 18, 21, 34, 60

There is an even amount of numbers, so you find the mean of the middle two numbers.

18+21=39/2=19.5

Median=19.5

Based on a​ survey, assume that ​48% of consumers are comfortable having drones deliver their purchases. Suppose that we wan
Andru [333]

Answer:

The value of n is the size of the sample, the number of customers selected.

The value of p is 0.48.

The value of q is 0.52.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

48% of consumers are comfortable having drones deliver their purchases.

This means that p = 0.48, q = 1 - p = 1 - 0.48 = 0.52

The value of n is the size of the sample, the number of customers selected.
