paring Data - Item 31786
A track coach is trying to improve the 50-meter-dash times of the track
team. He times each student and then implements a month-long
training program. At the end of the program, he timed each of the
students again. The box plots show the number of seconds it took the
students to run the 50-meter-dash before and after the program.
Using the plots, how much did the median change?

2x3 – 6x2 – 14x + 24 square centimeters

if i'm wrong i'm sorry : )

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

hello, never fear papaguy is here!

c. histogram

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
