Answer:240 m
Step-by-step explanation:
Given Balloon is going towards positive x direction with a speed of 10 m/s
and balloonist throw the ball with -2 m/s with respect to himself
thus absolute ball velocity is 12 m/s
As there is no horizontal force in x direction thus distance covered by ball in 20 sec is
R=
=240 m
Complete question :
Michael took 12 tests in his math class. his lowest score was 78. his highest score was 98. on the 13th test, he earned a 64. put a check in the correct box to indicate whether the value of each statistic below for his test scores increased, decreased, or cannot be determined when the last score was added.
1. Standard deviation 11) Median 111) Mean
Answer:
Standard deviation - increased
Median - cannot be determined
Mean - decrease
Step-by-step explanation:
The standard deviation will increase because the new (13th) test score does not fall within the range (lowest and highest) of the 12 previous test scores and will hence further increase the variability of the s ires measured
The Median cannot be determined as we need the data for the scores in other to determine the middle value of the test scores.
The mean value will decrease further because, when a score (64) lower that the previously recorded least score (78) is recorded and then the sum is recalculated and average taken. This low new score will cause the new to decrease further than previously recorded.
You could sort them by how many sides the figure has, then it would be split up into 2 groups, one group with 4 sides and another with 3
