<h3>The fifth one<em> would be the answer </em></h3>
Answer:
a = 9
b = 19
Step-by-step explanation:
DO B FIRST
The mean is the average of all the terms (numbers) in the sequence
To find the average you find the sum of the terms and divided the sum by the number of terms there are.
The mean times the number of terms equals the sum of all the terms subtract the terms that you know from the sum to get A
a = 17(10)-7-12-15-17-19-20-22-24-25
a = 170-161
a = 9
The median is found by taking the average of the two middle terms
Our middle terms are 17 and B
the median times 2 equals the sum of the two terms and then subtract the term you know from the sum
b = 18(2)-17
b = 36-17
b = 19
Step-by-step explanation:
I guess we only need to read the details of the already shown line (and don't need to calculate it from the scratch).
usually I am looking for points with integer coordinates to elaborate the equation.
I see here
(0, 2)
(3, 4)
(6, 6)
(9, 8)
the line equation is
y = ax + b
a being the slope, which is "y coordinate change / x coordinate change" when going from one point to another.
and b being the y-intercept (the y value when x = 0).
we know b already from the first point (0, 2) : b = 2.
so, for the slope we use e.g. the first 2 points
(0, 2) and (3, 4)
x changes by +3 (from 0 to 3).
y changes by +2 (from 2 to 4).
so, the slope is +2/+3 = 2/3
and the line equation is
y = 2/3 x + 2
or
y = 2x/3 + 2

If you would like to solve the equation a = 2 + 3a + 10, you can do this using the following steps:
<span>a = 2 + 3a + 10
</span>-2 - 10 = 3a - a
-12 = 2a /2
a = -6
The correct result would be -6.
