Answer:
0.5
Step-by-step explanation:
First find the mean of the data
3+4+4+5 = 16
16/4 = 4
Find the distance of each data to the mean
4-3 = 1
5-4= 1
4-4 = 0
4-4 = 0
Now find the mean of those
1+1+0+0 = 2
2/4
MAD = 0.5
When you plot the points and use the vertical line test, you'll see that none of the vertical lines go through two points. Therefore verifying that this set of points represents a function.
Answer:
B. (2a +3b)(4a -c)
Step-by-step explanation:
Group the terms pairwise, then factor each pair.
... (8a² -2ac) +(12ab -3bc)
2a is a common factor in the first pair of terms; 3b is a common factor in the second pair of terms. We can factor those out.
... = 2a(4a -c) +3b(4a -c)
Then we see that (4a-c) is a common factor in the result. We can factor that out.
... = (2a +3b)(4a -c) . . . . matches selection B
Answer:
38
Step-by-step explanation:
f(-9) is the value of f(x) when x = -9. Therefore, f(-9) = 4 from the graph. Doing the same with g(6), we can see that g(6) = 6. Our expression becomes:
-1 * 4 + 7 * 6
= -4 + 42
= 38
Only one line can pass through 2 points.
