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.

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
