18 tons and 42 pounds divided by 3=6 tons and 14 pounds
volume of square middle = 12 x 12 x 7 = 1008
if you put the 2 ends together it would be a cylinder so volume for that is:
3.14 x 6^2 x 7 = 791.28
1008 + 791.28 = 1799.28 round it off to 1800 mm^3
So D is the correct answer
43. 300 customers per day is the median of the distribution, so half of the measurements of customers per day are 300 or less. We could say, about half the time.
44. The quaritles of the distribution for Store A are evenly spaced, so we can say the distribution is symmetrical and nearly uniform.
For Store B, the longer distances between quartiles on the right and the long right-side "whisker" mean the distribution is skewed to the right.
45. The average and median are likely very close to the same for Store A, at about 300 customers per day. The average for Store B is likely slightly above its median of 350, so is more than 350 customers per day. The worst days for Store B are not as good as the best days for Store A, but, on average, Store B has more customers.
Answer:
The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.
Step-by-step explanation:
When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.
If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.
Answer: -0.85
Step-by-step explanation: a = score-mean/ standard deviation
Mean (add them all up and divide by amount) = 18.8745
Standard deviation =
σ2 = Σ(xi - μ)2/N
= 5.333458985499
SCORE = 14.23
= -0.85
