Answer:
Answer: Table 2 and table 3 are the functions which have an additive rate of change of 3.
Step-by-step explanation:
Step-by-step explanation:
The rate of change of a linear function is given by:-
For table 1,
.....> which is not positive.
For table 2,
.....> which is positive.
For table 3,
.....> which is positive.
Hence, Table 2 and table 3 are the functions which have an additive rate of change of 3.

Answer:
Both the mean and median and they both gives a measure of 17
Step-by-step explanation:
Given the data about the ages of 7 people :
17,20,22,12,15,12,21
Ordered data: 12, 12, 15, 17, 20, 21, 22
To find the median :
Median = 1/2 * (n+1)th term
n = number of observations = 7
Median = 1/2(7+1)th term
Median = 1/2 *8 = 4th term = 17
Mean = Σx / n = (sum of ages) / number of observations
Mean = 119 / 7 = 17
<em><u>Answer:</u></em>
12.8 or option 3
<em><u>Step-by-step explanation:</u></em>
So this is actually a proportion:
The large triangle to the smaller one:
<em>The angles of the triangles are the same so they are proportional</em>
We know the larger one is 20/8 times the smaller one's sides because
<em>YZ = something times QR so:</em>
20 = 8 times 20/8
In order to find PR, we have to divide ZX by the proportion rate thing so:
32 / (20/8)
= 32 * 8/20
= 64/5
= 12.8
Answer:
(2,2) x should be 2 and y should be 2 too
1/4= 2/8
3/8 + 2/8 = 5/8
