Answer:
B) Interquartile range
Step-by-step explanation:
Since there are some students that do not eat fast food at all, their amounts spent monthly would be $0. These are much different than the rest of the data, and thus are outliers.
Outliers can greatly affect the mean. This tells us the mean may not be the best measure.
Since the mean is affected by outliers, the standard deviation is not the best measure either.
Adding data points of 0 will also affect the range. This leaves the interquartile range as the better measure.
Answer:
there was a 16% increase since 2010 to 2012
Step-by-step explanation:
lets say the train had 100 people on it in 2010 and in 2011 it had an 8% increase which then brings you to 8 plus 100 and you get 108.
Now in 2012 there was an increase 8%, so you will add 8 to your previous answer 108 and receive 116. So now there was 16 more passengers in 2012 than in 2010. Transfer the 16 passengers into 16% and you now have your answer.
Answer:
155°
Step-by-step explanation:
∠EYV is half the difference of arcs EV and EH
(1/2)(EV -EH) = ∠EYV
(1/2)(EV -85°) = 35° . . . . fill in the given values
EV -85° = 70° . . . . . . . . .multiply by 2
EV = 155° . . . . . . . . . . . . add 85°
Answer:

Step-by-step explanation:
x - number of adults
y - number of campers
<em>The room for 200 people</em>: x + y ≤ 200
<em>Each adult costs $4, and each camper costs $3</em>: 4x and 3y
<em>A maximum budget of $750</em>: 4x + 3y ≤ 750
Answer:
Step-by-step explanation:
- −5.93 + (−8.62) + 5.93 =
- −5.93 - (8.62 - 5.93) = B
- −(5.93 + 8.62) + 5.93 = C
- −5.93 −8.62 - (- 5.93) = D
- -8.62 A
