Answer:
Letter B is the correct answer. Median is 4 and IQR is 5.
Step-by-step explanation:
Jason : 8,8,11,13,14,14,15,18,21,22,22,27,27,28,30
median = 18
IQR = 27 - 13 = 14
Ed : 7,12,12,15,19,21,21,21,21,22,23,23,26,27,27
median = 21
IQR = 23 - 15 = 8
Their medians cannot be compared based on their IQR's are 6 points apart
parallel
Because the 2 line have same slopes but different y int, they are parallel
25 gallons
Assuming miles-per-gallon is a constant, the amount of gas is proportional to the miles driven:
gallons/(500 mi) = (13 gal)/(260 mi)
gallons = (500 mi)/(260 mi)(13 gal) . . . . multiply by 500 mi
gallons = 25 gal . . . . do the arithmetic
The van will need 25 gallons of gas to go 500 miles.
