Answer:

the slope of the given line is -8

Step-by-step explanation:

(6,9) and (7,1)

To find the slope of the given line we use formula

slope = \frac{y_2-y_1}{x_2-x_1}

the value of x1 is 6 and y1 is 9

the value x2 is 7 and y2 is 1

plug in the value in the slope formula

slope = \frac{1-9}{7-6}=\frac{-8}{1}=-8

the slope of the given line is -8

if a cylinder with height 9 inches and radius r is filled with water, it can fill a certain pitcher. how many of these pitchers
dalvyx [7]

Answer:

4 pitchers

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

V=\pi r^{2}h

step 1

Find the volume of the cylinder  with height 9 inches and radius r

substitute the given values

V_1=\pi r^{2}(9)

V_1=9\pi r^{2}\ in^3

step 2

Find the volume of the cylinder  with height 9 inches and radius 2r

substitute the given values

V_2=\pi (2r)^{2}(9)

V_2=36\pi r^{2}\ in^3

step 3

we know that

The volume of the cylinder 1 can fill a certain pitcher,

so

The volume of the pitcher is the same that the volume of cylinder 1

therefore

the number of pitchers that can be filled by the second cylinder is equal to divide the volume of the second cylinder by the volume of the first cylinder

\frac{36\pi r^{2}}{9\pi r^{2}}=4\ pitchers

A random sample of individuals over the age of 18 are sampled and asked, "What is your level of education?" The results are summ
grigory [225]

Answer:

Check the explanation

Step-by-step explanation:

1.  The level of education as high school diploma (31% area).

Therefore the most frequent education level is High school Diploma.

2. Suppose there are 200 people in random sample. Pie diagram shows the percentage of people with Bachelor's degree is 19%

Therefore the number of people having Bachelor's degree among 200 people = 200×19% = 38

Therefore the answer is 38 .

3. Now the population size given is 6000. The percentage of individuals who have some collage but no degree is 17%

Therefore the number of individuals among 6000 individuals who have some collage but no degree = 6000×17% = 1020

Thereforethe answer is 1020 .

4. The percentage of individuals who have an associate's degree is 9% as per the pie diagram. The above pie diagram is based on a random sample of individuals. If we take another sample then also we may get different result. Therefore if we considere the entire population of U.S.A. the percentage of individuals who have an associate's degree may differ from 9% .
