Answer:
2x+8b
Step-by-step explanation:
First since 1 and 8b are on the same side mutiply them:
1bx8=8b
So our new equation is 2x+8b
Answer:
The mean.
Step-by-step explanation:
The mean is not robust.
The presence of an outlier greatly affects the value of a mean.
An example will illustrate this.
Find the mean of the numbers 2 3 5 6 34.
34 is an outlier. The mean = (2+3+5+6+34) / 5 = 10.
Now if we replace the outlier with a number closer to the others:
Say we have 2 3 5 6 8 :
The mean = (2+3+5+6+8) / 5 = 4.8 which is a much truer measure of centrality than 10.
Let the number of green apples bought be x
Green apples = x
Red apples = 2x
Yellow apples = 1/3 (2x) = 2/3 x
Total = 22 apples
x + 2x + 2/3 x = 22
11/3 x = 22
11x = 66
x = 6
Green apples = x = 6
Red apples = 2x = 2(6) = 12
Yellow apples = 2/3 (2x) = 2/3 (6) = 4
Answer: Green = 6, Red = 12, Yellow = 4
