Answer:
The standard error of the mean is 0.0783.
Step-by-step explanation:
The Central Limit Theorem helps us find the standard error of the mean:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation
.
The standard deviation of the sample is the same as the standard error of the mean. So

In this problem, we have that:

So



The standard error of the mean is 0.0783.
D.) x = - 9
C.) x = 0
Hope that helps, Good luck! (:
Answer:
Dee won
Step-by-step explanation:
Using < to mean "finished ahead of ", we are given ...
B = 3
D < B
D < C
A < C
D < A
Dee finished ahead of Air, Bart, and Caper, so Dee won the race.
_____
The order of finish must be D, A, B, C.
Answer: Chad has 11/ 12 paints altogether.
Step-by-step explanation:
Amount of yellow paint = 2/3
Amount of white paint = 1/4
total amount of white and yellow paint altogether
= 2/3 + 1/4
= 8+ 3/12
=11/12
Answer:
see below
Step-by-step explanation:
-2x^4-x^3+8x^2-12
First list by highest power to lowest power
The highest power is x^4 so this is a 4th degree polynomial or a quartic polynomial
If you really mean the multiply sign
-2x^4-x^3*8x^2-12
-2x^4 - 8x^5 -12
-8x^5 -2x^4 -12
This would be a 5th degree or quintic
