Answer:
The speed of the jet in still air is 260 miles per hour.
Step-by-step explanation:
Given that a small jet can fly 858 miles in 3 hours with a tailwind but only 702 miles in 3 hours into a headwind, to find the speed of the jet in still air the following calculation must be performed:
858/3 = 286
702/3 = 234
(286 - 234) / 2 = X
52/2 = X
26 = X
286 - 26 = 234 + 26
260 = 260
Therefore, the speed of the jet in still air is 260 miles per hour.
Answer:
x = 9
Step-by-step explanation:
x = 
x 6 = 9
The lower quartile is the 25th percentile.
Answer:
x = 13
Step-by-step explanation:
1765
x = 100 (9) + (7) 50 + (19) 20 + (7) 10 - 1765
x = 900 + 350 + 380 + 70 - 1765
x = 1700 - 1765
x = -65
65/5 = 13
x = 13
