Answer: The answer is attached in the figure.

Step-by-step explanation: Given are four different graphs and we are to check which one matches with the equation y = 2 - x.

We have the following points on this equation.

(0,2), (1,1), (2,0), etc.

When we try to match these points with the given graphs, the we see that these points does not match with the first, third and fourth graph. The only graph containing these points is second one.

Thus, the second option is correct. Also see the attached figure for the location of the three mentioned points.

What is the midpoints of a segment whose endpoints are (-3, 8) and (7, -2) ?

Sidana [21]

$M = (\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})$
$M = (\frac{7 - (-3)}{2}, \frac{-2 + 8}{2})$
$M = (\frac{7 - 3}{2}, \frac{6}{2})$
$M = (\frac{4}{2}, 3)$
$M = (2, 3)$

Determine whether the value is a discrete random variable, continuous random variable, or not a random variable. a. The number

Bumek [7]

Answer:

a. Discrete

b. Discrete

c. Not a random variable

d. Continuous

e. Discrete

f. Continuous

Step-by-step explanation:

The discrete random variable is countable while continuous random variable is measurable.

a. The number of fish caught is a discrete random variable because these are countable.

b. The number of text book authors are also countable so it is a discrete random variable.

c. The political party affiliation of adults is not a random variable because the political party affiliation depends on person's interest and it cannot be randomly assigned to person. Also random variable is the numerical outcome of random experiment whereas political affiliation is the categorical variable that results in non numerical responses such as Democrat, Republicans etc.

d. The square footage of a house is measurable and so it is a continuous random variable.

e. The number of free dash throw attempts are countable so it is a discrete random variable

f. The weight of Upper T dash bone steak is measurable and so it is a continuous random variable.
