Answer:
c. domain: {-2, 0, 2}, range: {-1, 1, 3}
Step-by-step explanation:
Given:
There are three points on the graph.
Locate the
and
values of the points on the graph.
The points are 
Domain is the set of all possible
values. Here, the
values are -2, 0 and 2.
So, domain is: {-2, 0, 2}.
Range is set of all possible
values. Here, the
values are -1, 1 and 3.
So, range is: {-1, 1, 3}
The greatest common factor is 2
This is because we start by taking the largest factor that goes into both coefficients. Since the first coefficient is 2, we have to try 2 and 1. Since 2 is larger and goes into 36 evenly, we use that.
Then we use the smallest number of each variable. There are 4 r's in both equations. So, that is the number that we take. There are 2 s's in the first term, so we take that number.
Median = middle number
Total ten numbers so
median = (17 + b)/2
given median = 18
so
(17 + b)/ 2 = 18
17+b = 36
b = 36 - 17
b = 19
Now you have the data set
7, a , 12, 15 , 17, 19, 20, 22, 24 , 25
Mean = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24 +25)/ 10
Given mean = 17
so
17 = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24 +25)/ 10
17 = (a + 161) / 10
a + 161 = 170
a = 170 - 161
a = 9
answer
a = 9
b = 19
If Sally already has 3 marbles and she finds 5 everyday. That means you add 5 until you get to 58. So in this case 5 times 11 is 55 + 3 is 58. Answer: It will take 11 days at this rate for her to have 58 marbles.
