Answer:
The equation is
The solution of the equation is x=10.
Step-by-step explanation:
The volume of a rectangular prism is found using the formula V = l · w · h, where l is the length, w is the width, and h is the height.
Let x ft be the widht of the stall, then the length of the stall is x+2 ft. If each stall must be 9 ft high, then the volume of the stall is
The volume of each stall is then
The width cannot be negative, thus,
Answer:
a) median= 25 mins
interquartile range= 19mins
b) the braineys
, because the braineys took 32mins on average and the cleverites took 25 mins on average which is 7 minutes more.
Step-by-step explanation:
a) find the median by going across the middle of the cumulative frequency (in this case, 40) until it hits the line (the cleverites) and move down to see the time in minutes. 25 mins.
to find the interquartile range, first find the lower quartile. So find the half of the median, or the quarter of the cumulative frequency ( 20) and go across until it hits the line and look down from that point to find the time ( 15 mins). Then, find the upper quartile by finding 3/4 or half+quarter of the cumulative frequency (60) and do the same with the line (34mins)
the interquartile is upper quartile - lower quartile
34-15= 19 mins
interquartile= 19 mins.
b) the average is the same as the median, so find the median for the cleverites and the median for the braineys, which is 25 mins and 32 mins, therefore the braineys took longer, thus was the slowest at completing the test on average.
Answer:the force of the strings are keeping it perpendicular

Answer:
18b-3c-10
Step-by-step explanation:
16b+5c-10-8c+2b
<h3>Combine like terms [ 16b+2b=18b] [5c-8c=-3c] [and then -10 is alone bc its doesnt have any friends to combine with.]</h3>
