Marta measured the temperature as 65°f. what is the margin of error?
a . 60°f to 70°f
b .64°f to 66°f
c .64.5°f to 65.5°f
d .65.5°f to 66.5°f

Option C is correct.

Step-by-step explanation:

" Margin of error, mathematically speaking, is the range around any numerical answer that’s given in survey report and how closely the results represent the population on the whole ".

Marta measured the temperature as 65°F.

As in option C when we add and subtract 0.5 units in the measured temperature we get 64.5°F and 65.5°F.

Hence these are the most closely related value to 65°F.

While in other options the value are not so closely related.

Hence, margin of error is 64.5°F to 65.5°F.

Hence, option C is correct.

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)

its b
