3. Camille rolls two number cubes together
and records the sum. If she does this
180 times, how many times should she
expect the sum to be 7? Explain your answer

30 times she should expect he sum to be 7.

Step-by-step explanation:

Here we have , Camille rolls two number cubes together  and records the sum. If she does this  180 times, We need to find how many times should she  expect the sum to be 7 . Let's find out:

Total number of outcomes are 36 ( there can be 36 pairs of sum possible ) , and favorable outcomes are :

i.e. 6 , So

Probability = ( Favorable outcomes )/( Total outcomes )

⇒

But , she does this  180 times so we have ,

⇒

⇒

Therefore , 30 times she should expect he sum to be 7.

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
