Answer:
a. 0.48
b. The 96% confidence interval for p is (0.457, 0.503).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
In a poll of 2000 likely voters, 960 say that the US spends too little on fighting hunger at home.
This means that 
.
This is the answer for question a.
96% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 96% confidence interval for p is (0.457, 0.503).
Answer:
B. The graph of the function starts high and ends high.
Step-by-step explanation:
Firstly, we need to determine the degree of the function F(x) = 2x⁴– x³ +5x-9
To find the degree of the function, we add the exponent of each variable, and the variable with the highest exponent is the degree of the exponent.
2x⁴ has degree of 4
– x³ has degree of 3
+5x has degree of 1
-9 has degree of 0
Therefore the degree of the function is 4. Since it is even, the graph would start and end in the same direction.
The coefficient of the highest degree is 2 (2x⁴) which is positive therefore The graph of the function starts high and ends high
A square has 4 sides.
If the perimeter around the square is 12cm, then you do 12 ÷ 4, which is 3.
Each side is 3cm long.

Answer:
Circle
Octagon
Step-by-step explanation:
There are no curves in a cube to make a circular cross section, and there aren't enough edges to make an octagon (just visualize)
