The range from 63 to 99 is where the overall population of people with red hair is most likely to fall in the interval.
To solve:
The margin of error is equal to z (p (p - 1) / n).
4% is the error margin, We may therefore change the values to:
0.04 = z ×√ (1 - 81/625) / 625)
Then, using a standard normal table, we determine the z-value for 95%, which is around 1.96.
0.04 = 1.96 × √(81/625) × (1 - 81/625) / 625)
When we solve for (1 - 81/625)/625", we get a value of around 0.0098.
Calculations for the range are now being achieved:
81 - (0.0098 5000) = 63
81 + (0.0098 5000) = 99
Therefore, the range of residents with red hair that contains the greatest likelihood of lying is from 63 to 99.

The interval in which the total number of residents with red hair is most likely to lie is approximately between 545 and 745.
To find the interval in which the total number of residents with red hair is most likely to lie, we can calculate the confidence interval based on the survey results and the margin of error.
The margin of error is given as 4%, which means we have a 96% confidence level (100% - 4%). This corresponds to a z-score of approximately 1.96 for a standard normal distribution.
First, we calculate the standard error using the formula:
Standard Error = sqrt((p * (1 - p)) / n),
where p is the proportion of red-haired residents in the sample (81/625) and n is the sample size (625).
Standard Error = sqrt((81/625) * (1 - 81/625) / 625) ≈ 0.0179.
Next, we can calculate the margin of error by multiplying the standard error by the z-score:
Margin of Error = 1.96 * 0.0179 ≈ 0.035.
Now, we can calculate the lower and upper bounds of the confidence interval by subtracting and adding the margin of error, respectively:
Lower bound = (81/625) - 0.035 ≈ 0.109.
Upper bound = (81/625) + 0.035 ≈ 0.149.
To find the range or interval, we can multiply the lower and upper bounds by the total number of residents (5000):
Lower bound (rounded) = 0.109 * 5000 ≈ 545.
Upper bound (rounded) = 0.149 * 5000 ≈ 745.
Therefore, the interval in which the total number of residents with red hair is most likely to lie is approximately between 545 and 745.

Money was placed in a savings account and earned 3/4 % interest paid annually. Samantha, Tony and Anuyia each wrote an equation to show the amount of money in the account after one year with a balance of M dollars. T represents the total amount of money in the account.
Samantha’s Equation: T = 1.075M
Tony’s Equation: T = M + 0.0075M
Anuyia’s Equation: T = M(1 + 0.0075M)
Since none of the equations were written the same, they decided to see if their equations would give the same answers by using a $75 balance. Solve this problem using each student’s equation.

NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!
Answer:
A = (1/2)Pa = Pa/2
You can multiply both sides by 2 to eliminate the fraction on the right side:
2A = 2(Pa/2) = Pa
Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:
(2A)(1/a) = 2A/a = (Pa)(1/a) = P
Rewriting:
P = 2A/a
You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

Answer:
Part A - D:8
Part B - C:140°
Solving/Reasoning:Part A: Vertical angles are always congruent.
Part B: If angles are supplementary, they need to equal 180 when added together. Since we know angle A is 40, we can subtract it from 180 and figure out what is left over that should be angle B.
40+B=180
B=180-40
B=140

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.
0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.
Answer: 1.08j
Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right
1.08j
I’m not 100% sure tho
The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.
Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket
= j + 0.08j
= 1.08j
Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
