3 is 300,000 in 345,268.19
Answer:
Step-by-step explanation:
Information given
number of people who rent their home
represent the sample size
represent the proportion of people who rent their home
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by
and
. And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
If we replace the values obtained we got:
To find the X intercept make y =0. Then factor out a negative on the side with the equation for each of the terms, so it becomes
0=-(x^2+x+3)
0=(x^2+X+3)
0-3=(x^2+X)
-3=x(X+1)
-3=X, X intercept -3,0
-3=(X+1)
-4=X, X intercept -4,0.
These are possible X intercepts you can check by using quadratic formula as well.
Let
be the amount of food needed for one man for one day. At the beginning, we have enough food for 400 men for 40 days, i.e.

After 10 days, the 400 men will have consumed

food, impliying that the food remaining is

If 200 more men join the garrison, there are now 600 men. Each of them requires
food each day, and there are
units of food remaining. They will last
days.
I'm Pretty Sure The Answer Is x=2
