Answer:
greg, 4 seconds
Step-by-step explanation:
find how long it takes each person to run 2km first.
distance/speed:
- pepper: 2/3 *60(seconds)=40 seconds
- Greg: 2/5 *60= 24 seconds
40-12=28 seconds, pepper will take 28 seconds to finish the race from the time greg starts. greg will win by 4 seconds
It is false that for visualizing the relationship between a numerical and a categorical variable, a mosaic
plot is useful. This is because the best plot to use for this kind of
relationship is the side by side box plot.
Comparing the
distribution of a numerical variable across the levels of a categorical
variable is something we usually consider in this type of relationship.
The levels of one categorical variable by means of a quantitative
variable is best compared by using the visual display called the side by side
boxplot. <span>By placing single boxplots adjacent to one
another on a single scale, the side by side box plot is constructed.</span>
The dots you see on step 1 and step 2 mean to multiply
when you divide a fraction you actually multiply it then whatever you get you simplify it. simple :) hope it helped
