The students found that .015 of the teachers were either brave or completely fear-
less. if 300 teachers fell into one of these categories, how many teachers were there
in all?

Total teachers = 20,000

Step-by-step explanation:

We have to find Total number of teachers.

Given is the decimal number(percentage) and number of teacher that lie in the category.

So,

we know that: percentage= obtained teachers / total teachers

Putting values:  0.015 = 300/ total teachers

                      total teachers = 300/0.015

                      total teachers = 20,000

I hope it will help you!

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
