Question 2 of 10 Two friends argue over who brushes their teeth more often. To settle the
argument, they keep track of the number of mornings and nights they brush
and calculate a probability. These are shown in the table.
Braxton
Arabella
0.79
0.85
Probability of
brushing in morning
Probability of
brushing in evening
0.81
0.72
Who is more likely to brush both morning and evening? Assume all events are
independent.
A. Arabella. She has a 0.72 probability of brushing both times.
B. Braxton. He has a 0.64 probability of brushing both times.
C. Arabella. She has a 0.61 probability of brushing both times.
D. Braxton. He has a 0.79 probability of brushing both times.

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
