Mark, carlos, ben, and taj ran the 1,600-meter relay today at the track meet. if their times were 55.2 seconds, 54.34 seconds, 55.15 seconds, and 52.08 seconds, what was their total time for the race (in seconds)?

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
