Answer:
The correct options are A and C.
Step-by-step explanation:
The given functions are
We have to find to solution for the equation
The solution of the above equation is the intersection of F(x) and G(x).
From the graph it is noticed that both graph intersects each other at (0,1) and (2,4).
The x-coordinates of these points are the solutions of the given equation.
Therefore the solution of given equation are 0 and 2.
Therefore option A and C are correct.
5:4 since p is equal to 5 and r is equal to 4

Answer: 151
Step-by-step explanation:
if prior population proportion is unknown , then the formula is used to find the sample size :
, where 
= Two tailed critical value for significance level of 
E = Margin of error.
Given : margin of error = 8%= .08
For 95% confidence level , two tailed critical value = 1.96
Now, the required sample size :
Hence, the size of the sample needed = 151.
Surface area = 2(12*12+15*12+15*12) = 1008
1008 * 4 = 4032
