A. for runners in a race, a low time means a faster run. the winners in a race have the shortest running times. is it more desirable to have a finish time with a high or a low percentile when running a race?
b. the 20th percentile of run times in a particular race is 5.2 minutes. write a sentence interpreting the 20th percentile in the context of the situation.
c. a bicyclist in the 90th percentile of a bicycle race completed the race in 1 hour and 12 minutes. is he among the fastest or slowest cyclists in the race? write a sentence interpreting the 90th percentile in the context of the situation.

yes

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
