Categorical variables can assume values from a range of possible options, whereas quantitative variables can assume possibly infinitely many values from a certain number range.

So, the answer is "the colour of the bookshelf", because there can only be a limited number of possible colours for the bookshelf, whereas its width (no matter the unit measure) and height could be any number.

(2,-1) <br> y-intercept -3 <br> slope 1/2<br><br> Write an equation with the given info above.
jek_recluse [69]

y-intercept -3  

slope 1/2

is sufficient info with which to write an equation for a straight line:

y = mx + b becomes y = (1/2)x - 3.

You should check this by determining whether or not (2,-1) satisfies this equation.

Find the maximum value of the function for the polygonal convex set determined by the given system of inequalities.
V125BC [204]

Answer:

A. at (8,7) the maximum value is 98

Step-by-step explanation:

First draw the region, that is bounded by all

inequalities. This is the triangle with vertices

(6,1), (2,5) and (8,7).

Now you can see where the line f(x,y)=7x+6y

intersect this region. The maximum value will be

at endpoints of this region:

• at (6,1), f(6,1)=7-6+6-1=42+6=48;

·

at (2,5), f(2,5)=7·2+6.5=14+30=44;

• at (8,7), f(8,7)=7.8+6-7=56+42=98.

Thus, the maximum value of the function is 98 at

the point (8,7).

The volume of a sphere whose diameter is 18 cm is
prohojiy [21]

Answer:

  = 3052.08 cm^3

Step-by-step explanation:

Volume of a sphere is given by

V = 4/3 pi r^3

We know the diameter is 18

d = 2r

18 = 2r

Divide each side by 2

18/2 =2r/2

9 =r

V = 4/3 pi 9^3

V = 4/3 pi (729)

V = 972 pi

Approximating pi by 3.14

V =972 (3.14)

  = 3052.08 cm^3

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel
gogolik [260]

Answer:

kevin is 6 years old

Step-by-step explanation:

Let Kevin's age now be a

Daniel's age now be b

Kevin is 3 years older than Daniel. -> a-3 = b

Two years ago, Kevin was 4 times as old as Daniel -> a-2 = 4(b-2) = 4b -8

-> a-3 -(a-2) = b - (4b-8)

-> - 1 = -3 b +8

-> -9 = -3b

-> b = 3

-> a = 6
