An English class took a field trip to a writing conference on a charter bus. They noticed that, even though they traveled in rain on the way back, the trip back took a shorter amount of time than the trip to the conference did. Which of the following is a valid conclusion? Assume the bus traveled the same route both directions and did not stop.
A.
The rain caused a decrease in travel time.

B.
There is a positive correlation between rain and travel time.

C.
An increase in the speed of the bus caused a decrease in travel time.

D.
There is no correlation between bus speed and travel time.

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
