Answer:
A=400, L=2W, L*W=A so, L*W=400, so, 400=2W*W or 200=W*W or 200=
, 
= W, L=2() and W=, W=14.14 and L=28.28
Step-by-step explanation:
Answer:
B. 49 + 5π
Step-by-step explanation:
9 + 9 + 18 + 8 + 5 = 49
C = πd
d = 18 - 8 + 5 = 5
Answer:
-31
Step-by-step explanation:
5 - (4 + 2)^2 = -31
Answer:
-5
Step-by-step explanation:
Given the two box plots showing the number of seconds the students completes the 50-meter-dash race before and after the program, we are to determine the difference between the median value of seconds before and after the program.
Median in a box plot is represented by the vertical line that divides the rectangular box in a box plot.
Thus, the median before the program = 15 seconds
The Median after the program = 10 seconds
The median change = 10 - 15 = -5 seconds.
This means, after the program, most of the students now finish the 50-meter-dash faster, about 5 seconds less the former seconds used before the program.
