Answer:

A) 20/6

B)21/16

C)21/10 or 2.1

Step-by-step explanation:

<h2>EDIT!: someone else who probably has a better understanding than me answered this and I've been doing this all wrong lol please ignore this .w.</h2>

to find any probability just find the total and then divide that by the number of whatever you're checking for, eg. parkour backgrounds.

7+3+4+6 = 20 total backgrounds

6 parkour backgrounds.

20/6 is your answer.

6 + 10 + 5 = 21 total marbles

10 + 6 = 16 non yellow marbles

21/16 is your answer.

6 + 10 + 5 = 21 total marbles

10 blue marbles

21/10 or 2.1 is your answer.

Answer:

Step-by-step explanation:

Range goes from the lowest point on a graph to the highest point, not including anything in between those 2 extremes. We will evaluate the quadratic for the values given. First f(2):

$f(2)=(2)^2-5$ so

f(2) = -1

Now, f(4):

$f(4)=(4)^2-5$ so

f(4) = 11

Now, f(7):

$f(7)=(7)^2-5$ so

f(7) = 44

The lowest y value is -1 and the highest is 44, so the range is from -1 to 44 (I can't tell which of your choices reflects that because it's too small!)
