Which of the following z-values, standard deviations, and sample sizes produce a margin of error of 0.95?
z = 2.14; s = 4; n = 9
z = 2.14; s = 4; n = 81
z = 2.14; s = 16; n = 9
z = 2.14; s = 16; n = 81

B. z = 2.14; s = 4; n = 81

Step-by-step explanation:

We know that,

Putting the values,

z = 2.14; s = 4; n = 9

z = 2.14; s = 4; n = 81

z = 2.14; s = 16; n = 9

z = 2.14; s = 16; n = 81

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
