Since there are 43560 feet in an acre, 285 feet is 0.654% of an acre.
Hope this helps!
Alright so lets start with an arbitrary amount of students. Just to help us visualize the problem.
Say, 100 students for the first year when it was founded?
So far,
1996 - 100 students
From 96' to 97', it doubles. So:
1996 - 100 students
1997 - 200 students
From 97' to 98', it doubles AGAIN.
1996 - 100 students
1997 - 200 students
1998 - 400 students
So, what the percentage increase from 100, to 400?
Well, 100 x 4 gives us 400, so it's a 400 percent increase.
Answer: The answer should be 9.2195
Step-by-step explanation:They tell us the point is 2.9 and they are asking the distance from the origin which is zero. So we can use pythagorean theorem. A²+B²=C² Look at it as a triangle. They have given us A and B, so you can find C² using those information. If you plot the point in the line you know that A=2 and B=9. Using the formula will be 2²+9²=C² ⇒ 4+81=C² ⇒ 85=C². To get rid of the power of 2 in c we have to square both side to cancel it out. C would equal 9.2195
And what happened?
you didn’t finish your sentence, lol
Solution :
This is the two tailed test.
The null hypothesis and the alternate hypothesis is as :
Null hypothesis is 
Alternate hypothesis is 
Therefore, the critical value of z is :
Now the test statics is :
The test statics is 0.878
We see that it is a right tailed test.
= 0.3800
Thus , P-value > α
So we fail to reject the null hypothesis.
