Hey, I have already answered these all questions except the last question in your previous question. Make sure to see them.

For the last question, the answer would be the second choice as when times keep flowing, the distance still remains the same (not to be confused with speed.)

Basically when times keep going, the distance will stay the same without any changes.

Step-by-step explanation:

Top down, left to right, the sums are ...

1/3 +3/6 = 2/6 +3/6 = 5/6 . . . pink

1 1/5 + 1 2/10 = 1 1/5 + 1 1/5 = (1 +1) +(1/5 +1/5) = 2 2/5 . . . green

2 2/6 +1 2/8 = 2 1/3 +1 1/4 = (2 +1) +(4/12 +3/12) = 3 7/12 . . . violet

1/7 +2/3 = 3/21 +14/21 = 17/21 . . . yellow

2 3/4 +2/6 = 2 9/12 +4/12 = 2 13/12 = 3 1/12 . . . brown

A randomly selected sample of 100 students had an average grade point average (GPA) of 3.2 with a standard deviation of 0.2.

Answer:

A. 0.020

Step-by-step explanation:

we calculate the standard error of the sample mean with the formula,

$E=\frac{s}{\sqrt{n} }$ ,

with E= standard error of the sample mean

s= standard deviation

n= sample

So,

s= 0.2

n= 100

$E=\frac{0.2}{\sqrt{100} } =\frac{0.2}{10}=0.02$
