Answer:
c. Three fourths of the data is greater than 65.
Step-by-step explanation:
- A. is right, half of the data does lie between 53 and 74.
- B. is right, when calculated, the range is 57.
- C. is wrong.
- D. is right, the median of the lower half of the data is 53.
- I've attached a helpful image of box-and-whisker plots!
2x²-5x+8=0
use the quadratic formula, x=(5+√39i)/4 of x=(5-√39i)/4
looks like the second choice is correct.
Answer:
(3)
Step-by-step explanation:
(1), (2) and (4)
can be written as Fr= p1-p2, F and r are inversely proportional
(3) r is directly proportional with F which is opposite to the given formula
hence this is incorrect

No, there isn't a more efficient way to solve this system.
Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.
