Step-by-step explanation:
Answer:
mean = 254.6
median = 120
mode = 60
midrange = 958
For average data sets i prefer by finding the mean
Step-by-step explanation:
mean :
(98+120+493+206+73+102+183+870+76+60+60+112+147+1018+201) ÷ 15 = 254.6
median : 60 60 73 76 98 102 112 120 147 183 201 206 493 870 1018
find the middle number
= 120
mode :
number that is more than one
= 60
midrange :
highest number - smallest number
= 1018 - 60
= 958
9514 1404 393
Answer:
421.4 miles
Step-by-step explanation:
The flight legs are orthogonal, so the distance can be found using the Pythagorean theorem:
1.2 h × 120 mph = 144 mi
3.3 h × 120 mph = 396 mi
The distance at the end of the second flight leg is ...
d = √(144² +396²) = √177552 ≈ 421.37
The plane is about 421.4 miles from its starting point.
_____
The heading to its end point is 20° +arctan(3.3/1.2) ≈ 90.02°.
