8a+16=32
-16 -16 (subtract 16 on both sides)
8a=16
÷8 ÷8 (divide 8 on both sides to get "a" by itself)
a=2
For any square the area is given by
where
is the length of one side. (This comes from the general rectangle formula
with
).
To solve for
we take the square root of both sides:
Now we can substitute known values:
3 + 0.45*M<=8,40. Notice the equal, because you may use all the money. Then, rearranging: M<=(8.40-3)/0.45= 12, so M<=12. Now, obviously time is positive, so you may end saying 0<=M<=12, with M=0 meaning no call! :)
Answer:
900
Step-by-step explanation:
Margin of error = critical value × standard error
The margin of error is given to be 0.05.
At 99.5% confidence, the critical value is z = 3.
The standard error for a proportion is √(pq/n). Since p is not given, we will assume p = 0.5.
0.05 = 3 √(0.5 × 0.5 / n)
n = 900
