Answer:
d. 200 and 2
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
Mean = 200
Standard deviation = 18
Sample size: 81
Standard error: 
So the correct answer is:
d. 200 and 2
Y+4= x blue bikes
G-2= x yellow bikes
4y+4= 8 blue bikes
4y+2= 6 green bikes
4y= 4 yellow bikes
8 blue bikes
+
6 green bikes
+
4 yellow bikes
=
18 bikes total
Answer:
bruh
Step-by-step explanation:
So "of" means multiply and 30% is .3 so multiply .3 by the 240 times and u get... 72!
Answer:
52.9°
Step-by-step explanation:
step 1
we know that
The total number of successful United States space launches that happened in the years 1957-1995 is equal to
step 2
The numbers of successful United States space launches that happened in the years 1980-1989 is equal to
step 3
The percentage of successful United States space launches that happened in the years 1980-1989 is equal to
step 4
Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989
we know that
In a circle, 360 degrees represent the 100%
so
using proportion
Find out the measure of the central angle by a percentage of 14.68%
