Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$f(x)=mx+b$

m - slope

b - y-intercept, (0, b)

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

From the graph we have two points A(-1, 2) and B(0, -1) → b = -1.

Calculate the slope:

$m=\dfrac{-1-2}{0-(-1)}=\dfrac{-3}{1}=-3$

Finally:

$f(x)=-3x-1$

Describe each of the following values as (A) a discrete random variable, (B) a continuous random variable, or (C) not a random v

Lyrx [107]

Answer:

(1) B

(2) A

(3) C

Step-by-step explanation:

A random variable is a variable that denotes a set of all the possible outcomes of a random experiment. It is denotes by a single capital letter such as X or Y.

There are two types of random variables.

Discrete random variable: These type of random variable takes finite number of values, such as 0, 1, 2, 3, 4, ... For example, number of girl child in a neighborhood.
Continuous random variable: These type of random variables takes infinite number of possible values. For example, the height, weight.

(1)

Exact weight of quarters now in circulation in the United States.

The variable weight is a continuous variable.

Thus, the exact weight of quarters now in circulation in the United States is a continuous random variable.

(2)

Shoe sizes of humans.

The shoe size of a person are discrete and finite values.

Thus, the shoe sizes of humans are discrete random variables.

(3)

Political party affiliations of adults in the United States.

This variable is not a quantitative variable.

It is a qualitative variable.

Thus, the political party affiliations of adults in the United States is no random variable.

kelli and her faimly went to the beach for a vacation. they drove 293 miles 7 hours to get theredid they drive each hour

Inessa [10]

Ok so, Since Kelli and her family drove a total of 293 miles in 7 hours, then your equation should be $\frac{293miles}{7hrs}$
Now, since you have your ratio you divide 293 by 7 in order to get how many miles were driven in one hour
$\frac{293}{7}$ = 41.85714286 miles/hr

The ratio of the number of male lions to female lions in the animal reserve is 21:20. If there are 123 lions in the animal reser

Vanyuwa [196]

21 + 20 = 43

Total is 123, so divide by 43.

123/43 = 2.86 rounded to 3.

(females) 20 x 3 = 60 female lions
