Answer:
The sample proportion is 0.36635
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
The sample proportion is the halfway point betwen those two bounds, that is, the sum of those bounds divided by 2.
In this problem, we have that:
Lower bound: 0.2931
Upper bound: 0.4396
What is the sample proportion?
(0.2931 + 0.4396)/2 = 0.36635
The sample proportion is 0.36635

Answer:
at x = 10, 
Step-by-step explanation:
The given equation is 
Here, lets substitute the value of x = 10
So, the equation simplifies to ,
= (4 x 100) + 170 + 2 = 400 + 170 + 2
= 572
So, at x = 10, 
Answer:
It isn't necessary but having a positive coefficient for 
makes things like completing the square and factoring easier.
