Answer
Question 3
Option A is correct.
Margin of Error = 0.071
Question 4
Option A is correct.
95% Confidence interval = 0.062 < p < 0.121
Explanation
Question 3
Confidence Interval for the population proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample proportion) ± (Margin of error)
Margin of Error is the width of the confidence interval about the mean.
Now, here, we are given the confidence interval and asked to find the margin of error.
Sample Proportion = Population proportion = p
Let Margin of Error be E
Lower limit of confidence interval = p - E = 0.179
Upper limit of confidence interval p + E = 0.321
Now, we have a simultaneous equation
p - E = 0.179
p + E = 0.321
Add the two equations
2p = 0.179 + 0.321
2p = 0.5
Divide both sides by 2
p = 0.25
We can then solve for E
p - E = 0.179
0.25 - E = 0.179
E = 0.25 - 0.179
E = 0.071
Question 4
Confidence Interval for the population proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample proportion) ± (Margin of error)
Sample proportion = p = (33/362) = 0.0912
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error)
Critical value at 95% confidence interval for sample size of 362 is obtained from the z-tables.
Critical value = 1.960
Standard error or deviation of the sample proportion = σₓ = √[p(p – 1)/n]
p = 0.0912
1 - p = 0.9088
n = sample size = 362
σₓ = √[(0.0912 × 0.9088)/362] = 0.0151
95% Confidence Interval = (Sample proportion) ± [(Critical value) × (standard Error)]
CI = 0.0912 ± (1.96 × 0.0151)
CI = 0.0912 ± 0.0297
95% CI = (0.062, 0.121)
95% Confidence interval = 0.062 < p < 0.121

Step-by-step explanation:

3/7 is it< or> then 3/5
Two ways of solving:
1. Convert the fractions to decimals:
3/7 = 0.42857
3/5 = 0.6
0.42857 < 0.6
So 3/7 < 3/5
Second way is to rewrite the fractions with a common denominator:
3/7 = 15/35
3/5 = 21/35
Now compare the numerators:
15 < 21 so 3/7 < 3/5

Answer:
8
Step-by-step explanation:
56 shirts were sold, and including Mandy, 7 people sold them.
7 * x = 56
(7x)/7=56/7 (canceling out the 7 to get x alone)
x=8

Answer:
77
Step-by-step explanation:
Currently:
Talk to 8 customers per hour, work 8 hours, so:
Talk to 8*8 = 64 customers.
With the increase:
Has to increase by 20%, so 64 is multiplied by 1 + 0.2 = 1.2. Then
64*1.2 = 76.8
Rounding up, 77 is the answer.
Which is the equation of a line that has a slope of 1 and passes through point (5, 3)?
y = -2
y = x + 2
y = x + 3
y=x-5
Answer:
y = x - 2
Step-by-step explanation:
y = x + b
3 = 5 + b
y = x - 2
We can use the slope intercept form of a line.
y = mx+b where m is the slope and b is the y intercept
y = 1x +b
Substitute the point into the equation
3 = 1*5+b
3 = 5+b
Subtract 5 from each side
3-5 = 5+b-5
-2 =b
y = x-2
\(0=24-16t^2\)
Answer:
Step-by-step explanation: Simplify both sides of the equation.
0=−16t2+24
Step 2: Add 16t^2 to both sides.
0+16t2=−16t2+24+16t2
16t2=24
Step 3: Divide both sides by 16.
16t^2/16=24/16
t^2=3/2
Step 4: Take square root.
t=± √ 3/2
t=1.224745,−1.224745

a. The center of the circle is (-2, -1).
b. The radius of the circle is √136.
c. The equation of the circle is (x + 2)^2 + (y + 1)^2 = 136.
a. To find the center of the circle, we can use the midpoint formula, which states that the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by:
Midpoint = ((x1 + x2)/2, (y1 + y2)/2)
In this case, the endpoints of the diameter are P(-7, -4) and Q(3, 2).Applying the midpoint formula:
Midpoint = ((-7 + 3)/2, (-4 + 2)/2)
= (-4/2, -2/2)
= (-2, -1)
Therefore, the center of the circle is at the coordinates (-2, -1).
b. To find the radius of the circle, we can use the distance formula, which calculates the distance between two points (x1, y1) and (x2, y2). The radius of the circle is half the length of the diameter, which is the distance between points P and Q.
Distance = √\([(x2 - x1)^2 + (y2 - y1)^2]\)
Using the distance formula:
Distance = √[(3 - (-7))^2 + (2 - (-4))^2]
= √\([(3 + 7)^2 + (2 + 4)^2]\)
= √\([10^2 + 6^2\)]
= √[100 + 36]
= √136
Therefore, the radius of the circle is √136.
c. The equation for a circle with center (h, k) and radius r is given by:
\((x - h)^2 + (y - k)^2 = r^2\)
In this case, the center of the circle is (-2, -1), and the radius is √136. Substituting these values into the equation:
\((x - (-2))^2 + (y - (-1))^2\) = (√\(136)^2\)
\((x + 2)^2 + (y + 1)^2 = 136\)
Therefore, the equation of the circle is (x + 2)^2 + (y + 1)^2 = 136.

Determine whether [3x + 12 + x] is equivalent to [4(3 + x)]. Use properties of operations to justify your answer.
Answer:
3x + 12 + x = 4x + 12 becuase 3x and x are like terms so you can add them
4(3 + x) = 12 + 4x because 4 times 3 is 12 and 4 times x is 4x so you add them to get 12 + 4x which can be rearranged to equal 4x + 12
So in short: 3x + 12 +x is equivalent to 4(3+x)

Answer:
x = 35
Step-by-step explanation:
since the figures are similar then the ratios of corresponding parts are in proportion, that is
\(\frac{x}{10}\) = \(\frac{14}{4}\) = \(\frac{7}{2}\) ( cross- multiply )
2x = 7 × 10 = 70 ( divide both sides by 2 )
x = 35
You have $300,000 to invest. There are 2 possible investments you can make. Super Apple Sauce will return $135 for every $57 invested in 5 years and Markers Inc. will return $5 for every $1 invested in 5 years.

What is the Total Return for each (answer as a percent)?
Super Apple Sauce Total Return =
%
Markers Inc Total Return =

The APY for super apple sauce APY is 13.4%, markers inc APY is 37.9%. The total return for super apple sauce is 137%, markers inc is 400%.
What is interest?Interest refers to the amount of money that is charged or earned in relation to a principal amount of money.
According to question:To calculate the APY (annual percentage yield) for each investment, we need to use the following formula:
APY = (1 + r/n)^n - 1
1) For Super Apple Sauce, the return is $135 for every $57 invested in 5 years. Annual interest rate of:
r = (135/57)^(1/5) - 1 ≈ 0.134
Since the interest is compounded yearly, n=1. Using the formula, we get:
APY = (1 + 0.134/1)^1 - 1 ≈ 0.134 or 13.4%
Therefore, the APY for Super Apple Sauce is approximately 13.4%.
2) For Markers Inc., the return is $5 for every $1 invested in 5 years. Annual interest rate of:
r = (5/1)^(1/5) - 1 ≈ 0.379
Since the interest is compounded yearly, n=1. Using the formula, we get:
APY = (1 + 0.379/1)^1 - 1 ≈ 0.379 or 37.9%
Therefore, the APY for Markers Inc. is approximately 37.9%.
The total return for each investment:
Total Return = (Ending Value - Beginning Value) / Beginning Value
3) For Super Apple Sauce, the beginning value is $57 and the ending value is $135, so the total return is:
Total Return = ($135 - $57) / $57 ≈ 1.37 or 137%
Therefore, the total return for Super Apple Sauce is approximately 137%.
4) For Markers Inc., the beginning value is $1 and the ending value is $5, so the total return is:
Total Return = ($5 - $1) / $1 = 4 or 400%
Therefore, the total return for Markers Inc. is 400%
