The double dot plot shows the values in two data sets. Express the difference in the measures of center as a multiple of the measure of variation
Data set A
Data set B
..
10 15 20 25 30 35 40 45 50 55
The difference in the means is about
times the MAD

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

12.5 feet

step-by-step explanation:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
