Four out of every five teenagers surveyed went to a movie theater in the past month. if 95 teenagers were surveyed, how many had gone to the movies in the past month?

76 teenagers went to movies in the past month.

Step-by-step explanation:

The number of teens who went to movie out of every 5 teens  = 4

Total teens surveyed = 95

Let, out of 95 teenagers , the teens who went to movie = m

So, the ratio  of people who went : who were surveyed = 4: 5

Now,  BY THE LAW OF RATIO AND PROPORTIONALITY

or,

So, m = 76

⇒ 76 teenagers went to movies in the past month.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
