Soda tak claims that diet tak has 40mg of sodium per can. you work for a consumer organization that tests such claims. you take a random sample of 60 cans and find that the mean amount of sodium in the sample is 41.9mg. the population standard deviation in all cans is 5.2mg. you suspect that there is more than 40mg of sodium per can. find the z-score.

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)
