3. What is the median of the morning (AM) group? What is the median of the afternoon (PM) group? (2 points: 1 point for each answer)
Morning (AM): 25.5
Afternoon (PM): 19
4. What is the first quartile (Q1) of the morning (AM) group? What is the first quartile (Q1) of the afternoon (PM) group? (2 points: 1 point for each answer)
Morning (AM): 10
Afternoon (PM): 0
5. What is the third quartile (Q3) of the morning (AM) group? What is the third quartile (Q3) of the afternoon (PM) group? (2 points: 1 point for each answer)
Morning (AM): 20
Afternoon (PM): 10
6. What is the interquartile range (IQR) of the morning (AM) group? What is the interquartile range (IQR) of the afternoon (PM) group? (2 points: 1 point for each answer)
Morning (AM): 39
Afternoon (PM): 29
7. The average weights of the dogs are the same for the morning and afternoon groups. But based on your comparative box plot and the IQRs of the two groups, which group of dogs does you think would be easier to walk as one group? Why? (2 points: 1 point for the answer, 1 point for justification)
The morning dogs, there are fewer dogs and they seem to weigh less.

Area of triangle ABC = 80 square units
Step-by-step explanation:
We need to find the area of triangle ABC when we are given:
a= 15, b=12 and C=63°
We can find area of triangle using SAS (Side Angle Side)
The formula used is:
We are given a= 15, b=12 and C=63°, Putting values in the formula
Solving
So, Area = 80.19
Rounding off to nearest whole number:
Area = 80 square units

Answer:
13525
Step-by-step explanation:
Given the equation :
y=25,450(0.81)^t
where (t) is the number of years since the truck was new ;
The value of y when t = 3 ;
Replace, t with 3 in the equation. And simplify
y=25,450(0.81)^3
Y = 25450 * 0.531441
y = 13525.17345
Worth after 3 years = 13525
