A political candidate has asked his/her assistant to conduct a poll to determine the percentage of people in the community that supports him/her. If the candidate wants a 10% margin of error at a 90% confidence level, what size of sample is needed? Be sure to round accordingly. The candidate would need to survey people in the community in order to be within a 10% margin of error at a 90% confidence level.
Answer:
The size of the sample needed = 67.65
Explanation:
Given that :
The margin of error = 10% = 0.10
The confidence level = 90% = 0.90
Level of significance = 1 - 0.90 = 0.10
At ∝ = 0.10
[tex]Z_{\alpha/2}= Z_{0.10/2} = 1.645[/tex]
Since the proportion of people that supported him/her is not given, we assumed p = 0.50
The margin of error formula can be expressed as:
[tex]M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{p(1-p)}{n}}[/tex]
[tex]0.10 = 1.645 \times \sqrt{{\dfrac{0.5(1-0.5)}{n}[/tex]
Squaring both sides; we have:
[tex]0.10^2 = 1.645^2 \times {\dfrac{0.5(1-0.5)}{n}[/tex]
[tex]0.01 = 2.706025 \times \dfrac{0.25}{n}[/tex]
[tex]n= 2.706025 \times \dfrac{0.25}{0.01 }[/tex]
n = 67.65
Therefore, the required sample size = 67.65

A certain student has taken 74 credit hours so far in college. The equation 14x + 16y= 74
represents this situation, where x is the number of fall semesters and y is the number of spring
semesters in which the student has taken classes. How many more credit hours did the student take
in each spring semester than in each fall semester?
Answer:
2 credit hours
Explanation:
Given
14x + 16y = 74
Required
Determine the number of credit hours y greater than x
From the question, we understand that
y => spring semesters
x => fall semesters
From the equation,
14 represent the number of credit hours in each fall semester
16 represent the number of credit hours in each spring semester
Calculate the difference.
Difference = 16 hours - 14 hours
Difference = 2 hours
Hence, the student take 2 more hours in each spring semester than in each fall semester

If the probability of her losing any
drawing competition is 0.7, find the probability of her winning
a) at least one competition.
b) exactly two competitions.
Answer:
In the first case, you have three entries out of 50, so your chance of winning assuming all drawings have equal chance of being picked is
In the first case, you have three entries out of 50, so your chance of winning assuming all drawings have equal chance of being picked is350=0.06.

The length of one side of a rectangle is 12 units longer than the length of another side. The rectangle's area is 220 square units. What is the length, in units, of the shorter of these two sides?
Answer:
Length of the shorter side = -10 units or 22 units.
Explanation:
Let x = length of the longer side of the rectangle
Let y = length (width or breadth) of the shorter side of the rectangle
Given the following data;
x = y + 12
Area = 220 units
We know that the area of a rectangle is given by the formula;
[tex] Area, A = length * width[/tex]
Substituting into the equation, we have;
[tex] 220 = (y + 12) * y[/tex]
[tex] 220 = y^{2} + 12y[/tex]
Rearranging the equation, we have;
[tex] y^{2} + 12y - 220 = 0[/tex]
Solving the quadratic equation by factorization, we have;
Factors are = -10 and 22
[tex] y^{2} - 10y + 22y - 220 = 0[/tex]
[tex] y(y - 10) + 22(y - 10) = 0[/tex]
[tex] (y - 10)(y + 22) = 0[/tex]
Therefore, y = 10 units or -22 units
To find the value of x;
When y = 10 units
x = y + 12
Substituting into the equation;
x = 10 + 12 = 22
x = 22
When y = -22 units
x = y + 12
Substituting into the equation;
x = -22 + 12 = -10
x = -10
Check;
When x = 22 and y = 10
A = L * W = 22 * 10 = 220 units
When x = -10 and y = -22
A = L * W = -10 * -22 = 220 units
