Answer:
(D)
Step-by-step explanation:
The graph shows the arm span lengths of the students, clearly we can see that the most of the students have arm span length in the initial points of the length.
Median = Middle frequency of the data. Here, median will be the length in the middle.
Mode = Most frequently occurring number in the data. Here the mode will be the length which most of the students has.
Clearly, most of the student has the length in the initial inches while the median will be in the middle.
Hence, mode will be less than the median.
use the pythagorean theorem: a^2 + b^2 = c^2
6^2 = 36
4^2 = 16
36-16 = 20.
the square root of 20 is either a.) the square root of 20 or b.) 4.4721... (rounded 4.5)
Answer:
80 miles
Step-by-step explanation:
Speed is 30 miles/hour
Time is 2 hours 40 minutes or 2 2/3 hours or 8/3 hours
Distance is speed x times
so distance is 30 x 8/3 = 80 miles
Answer:
Helen is 24; Robert is 39
Step-by-step explanation:
If Helen's age is x, Robert's age is x + 15. We can write:
x + x + 15 = 63
2x + 15 = 63
2x = 48
x = 24
This means that Helen's age is 24 and Robert's age is 24 + 15 = 39.
