Answer:
(-1, 3)
Step-by-step explanation:
to solve using substitution, you have to know the value of either x or y. in this example, they gave you the value of y already: y=x+4.
this means you can substitute the y for (x+4). if we substitute y for (x+4) in the equation y=-5x-2, we get this:
(x+4)=-5x-2
then solve for x
6x=-6
so x=-1
since we know the x value, we can solve for y
y=x+4
y=-1+4
y=3
so the final answer is (-1, 3)
Answer:
2.33.
Step-by-step explanation:
First we find the mean by adding the values and dividing by 11 (the number of values).
mean = 62 / 11
= 5.636
Now, we list the absolute differences between each value and the mean:
9 - 5.636 = 3.364 the others are:
3.636, 3.636, 0.636, 2.636, 3.364, 0.364, 4.364, 1.636, 1.364, 0.636
Now the MAD is the sum of these values / 11.
MAD = 25.636/11
= 2.33..
The MAD for City 1 is 24.
The MAD for City 2 is 11 1/3.
The MAD for City 2 is less than the MAD for City 1, which means the average monthly temperatures of City 2 vary less than the average monthly temperatures for City 1.
