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:
B
Step-by-step explanation:
Given
2x² - 4x = 14 ( divide through by 2 )
x² - 2x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 7 + 1
(x - 1)² = 8 → B
Well frist you cant do 189 from 643. u have to do 643 - 189.and that well be 743
