Question 6 of 10
Secti
A teacher is deciding which measure of center describes the recent test scores of his Geography class. He asks his teammates to help him
decide.
Sect
The test scores are as follows: 50, 50, 50, 60, 60, 60, 70, 70, 80, 80, 80, 90, 90, 90.
Sect
Eden says he should pick the median. Chen says he should pick the mean. Ellen says he should pick the mode. Hans says it does not
matter, so he could pick the mean or the median.
Sect
Which teammate is right and why?
Secti
Sect
A) Eden is right because it is skewed to the right.
Secti
B Chen is right because it is skewed to the left.
Sect
Ellen is right because it is symmetric.
SECT
D) Hans is right because it is symmetric.
E None of the teammates are right.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

what statement? is there an image?
