Answer:
And we have a sample size of n =81. We want to estimate the standard error of the sampling distribution 
and for this case we know that the distribution is given by:
And the standard error would be:
And replacing we got:
Step-by-step explanation:
For this case we know the population deviation given by:

And replacing we got:
Answer:
5/6
Step-by-step explanation:
we add all the marbles together to get 6
then we seperate the marbles according to the question which would be yellow and red. that would make the probability of getting one of those to 5/6. Hope this helps :)
The computation shows that the value of blue which is represented by x is 12.
<h3>How to calculate the value?</h3>
From the information given, it was stated that 30 people were in the kindergarten.
Green = 10
Red = 8
Blue (x) = 30 - (10 + 8)
= 30 - 18
= 12
Since the teacher want to paint the class with the most favorite color, the appropriate color to use will be blue.

Answer:
D = 12 Miles from her house to Fixit.
Step-by-step explanation:
Speed =Distance travelled/ Time
Time =Distance travelled/ Speed
T = D / 30 The time it took her to drive to Fixit.
T = D / 20 The time it took her to ride the bus home.
D / 30 + D / 20 = 1 hour, solve for D,
