Answer:
54 square units
Step-by-step explanation:
144 - 18 - 4(18) = 54 square units
Quadratic is the y=2x^2
that is the parabola one
when will the exponential one be higher than the parabola?
that is, hmm, find the intersection points
we can see that x=1 is an intersection point
we see that it is between the intersection points
if we use our calculator
intsersect at x=-0.578621 and 1
so it is the one from -0.5 to 1
that is the 3rd option
-0.5≤x<1
You can break 11/5 into 10/5 and 1/5
10/5 = 2
so the mixed number is 2 1/5
1/1 = 1
1/2 = 0.5
1/3 = 0.3
1/4 = 0.25
1/5 = 0.2
vvvvvvvv
1/6 = 0.16
^^^^^^^^^
Answer: 385
Given: error: 6 months, standard deviation = 5 years is 60 months
Step 1: find the minimal sample size ‘n’ for 95% confidence interval
1-0.95= 0.05
0.05/2= 0.025
Step 2:
1-0.025= 0.975
