Answer:
0.8418
Step-by-step explanation:
We have p = 0.36
Sample size = 200
We have to find the standard error of proportion
= √p(1-p)/n
= √0.36(1-0.36)/200
= 0.034
P(0.30<p^0.40)
= 0.30-0.36/0.034 = -1.76,
0.40-0.36/0.034 = 1.18
P(-1.76<z<1.18)
When we go to the standard normal distribution table
P(z<1.18) = 0.8810
P(z<-1.76) = 0.0392
0.8810 - 0.0392
= 0.8418
This is the probability of the sample proportion being between 0.30 and 0.40
Answer:
the set of whole number since it is defined as positive integers + zero
Answer:
Step-by-step explanation:
If 
exist, then we have that 
.
Therefore, in the case that 
, if we multiply both
terms in the equation by , then we have
and so the equation tells us that
.
V = length x width x height
In this problem:
length = 3
width = 3
height = 6
V = 3 x 3 x 6
V = 54 ft^3
Hope this helps!! :)
Since you provide no information about the median salary, i'm gonna use the national data, whcih is around $ 13,000 per year
Cost of education for 2 year = $30,000
Since he's still working in those 2 years, he'll earn = $ 26,000
Which means he just need to work for around half a year to cover the remaining $4,000 , so i think the answer is 2.5 years
hope this helps
