the standard deviation of 100 random samples of the same size is approximated to be 0.98. what is the margin of error

pogonyaev

Answer:

MOE= ± 0.098

Step-by-step explanation:

-The margin of error is calculated using the formula:

$MOE=\pm \frac{\sigma}{\sqrt{n}}$

#Substitute to solve for MOE:

$MOE=\pm \frac{\sigma}{\sqrt{n}}\\\\=\frac{0.98}{\sqrt{100}}\\\\=\pm 0.098$

Hence, the margin of error is ± 0.098

What is the value of x? <br> 64 68<br> (8x -12)<br> (2x + 18)

tamaranim1 [39]

(8x - 12) + 64 + 68 = 180
(A straight line equals to 180)
8x - 12 + 132 = 180
Combine liked terms
8x + 120 = 180
-120 on both sides
8x = 40
/8 on both sides
x = 5

(8x - 12)
8(5) - 12
40 - 12
28

(2x + 18)
2(5) + 18
10 + 18
28

Answer:
x = 5
