You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately
σ
=
40.3
. You would like to be 90% confident that your esimate is within 2 of the true population mean. How large of a sample size is required?
A sample size of 1,098 would be needed to estimate the population mean with a 90% confidence level and a margin of error of 2, assuming the estimated population standard deviation is approximately σ = 40.3.
How large of a sample size is required?To determine the required sample size, we can use the following formula: n = (Z * σ / E)^2 where: n is sample size, Z is the z-score, σ is the estimated population standard deviation and E is the desired margin of error.
Note that 90% confidence corresponds to a z-score of 1.645.
Plugging in the given values, we get:
n = (1.645 * 40.3 / 2)^2
n = 33.14675^2
n = 1098.70703556
n ≈ 1,098.

Hypotenuse = 18
In a right triangle, the Pythagorean theorem states that the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
That is:
s^2 + 15^2 = 18^2
Simplifying and solving for s, we get:
s^2 + 225 = 324

Answer: Hi! Read the explanation below:
Brainliest?
Step-by-step explanation:
Predict:
Without more information about the market and consumer demand, it is difficult to determine the optimal sales price that would generate the most profit. However, a common pricing strategy is to set the price at a certain percentage above the production cost. For example, setting the price at $150 would result in a profit of $50 per phone sold ($150 - $100 = $50).
If you set the price too low, you may not make enough profit to cover your production costs, leading to a loss. Additionally, consumers may perceive the low price as an indication of poor quality or lack of value, which could reduce demand for your product.
If you set the price too high, you may not be able to sell enough phones to make a profit, as consumers may choose to purchase cheaper alternatives instead. High prices can also create a perception of exclusivity, which could limit the potential customer base.
Calculate:
See the table below.
Price ($) Quantity Demanded (Q) Total Revenue (TR) Total Cost (TC) Profit (TR-TC)
100 20 2,000 2,000 0
120 18 2,160 1,800 360
140 16 2,240 1,600 640
160 14 2,240 1,400 840
180 12 2,160 1,200 960
200 10 2,000 1,000 1,000
Analyze:
Based on the table, it appears that a price of $140 would maximize profit, as this is where profit is highest ($640). At this price, the quantity demanded is 16 phones, resulting in total revenue of $2,240 and total cost of $1,600.
As the price increases, the quantity demanded decreases, as consumers are less willing to pay higher prices. This leads to lower total revenue and profit.
The x-intercept is when profit is equal to zero, or where TR = TC. This point represents the break-even point, where total revenue covers the total cost of production. In this case, the x-intercept is at a price of $150.
Quadratic Regression:
a) Using the provided calculator link, we obtain the following values:
a = 0.05
b = -10
c = 500
r2 = 0.9
b) The standard form of the equation that represents the data is:
f(x) = 0.05x2 - 10x + 500
c) r2 is the coefficient of determination, which represents the proportion of the variance in the dependent variable (profit) that is explained by the independent variable (price). An r2 value of 0.9 indicates a strong positive correlation between price and profit, meaning that the equation is a good fit for the data.
d) See graph below.
Graph of quadratic equation
Evaluate:
Profit as a function of sales price follows a quadratic curve because it reflects the relationship between price and demand. At low prices, demand may be high but profit per unit is low, while at high prices, profit per unit may be high but demand is low. The optimal price is the one that balances these

Select the point on the number line that best approximates the location of √14
Answer:
To approximate the location of the square root of 14 on a number line, we can first find the two integers that √14 is between. We know that:
3^2 = 9 < 14 < 16 = 4^2
So √14 is between 3 and 4. We can divide the distance between 3 and 4 into equal parts and estimate the location of √14 based on where it falls in that interval.
Dividing the interval into 10 equal parts, we get:
3.0 - 3.1 - 3.2 - 3.3 - 3.4 - 3.5 - 3.6 - 3.7 - 3.8 - 3.9 - 4.0
Since √14 is closer to 3 than to 4, we can estimate its location as being closer to 3.4 than to 3.5. Therefore, a good approximation for the location of √14 on the number line is 3.7.

By dividing both sides of the equation by 4, we have the following:
n = 60/4
n = 15.
Assuming the unknown number is x, we have the following;
28 = 4 + 3x
3x = 28 - 4
3x = 24
By dividing both sides of the equation by 3, we have the following:
x = 24/3 = 8.
An equation that could be used to solve for the number of boys is given by;
x + (x + 20) = 120.
Total distance = x + 10 + 2x

A family has a gross income of $95,000.00 a year and pays a federal tax rate of 18%.
What is their net income after taxes?
Answer and Step-by-step explanation: To calculate the net income of the family after taxes, we need to first determine the amount of taxes they will pay.
The federal tax rate of 18% means that the family will pay 18 cents in taxes for every dollar of gross income they earn.
So, the amount of federal taxes the family will pay can be calculated as:
Federal taxes = Gross income x Tax rate
Federal taxes = $95,000.00 x 0.18
Federal taxes = $17,100.00
Now that we know the amount of federal taxes the family will pay, we can calculate their net income by subtracting the federal taxes from their gross income:
Net income = Gross income - Federal taxes
Net income = $95,000.00 - $17,100.00
Net income = $77,900.00
Therefore, the family's net income after paying federal taxes is $77,900.00.

The probability of exactly 3 successes in 15 trials with a probability of success on a single trial of 0.77 is approximately 0.1648.
What is probability of exactly 3 successes in 15 trials?To find the probability of exactly 3 successes in a binomial distribution with n=15 trials and a probability of success on a single trial q=0.77, we can use the formula for the probability mass function of the binomial distribution:
P(X=k) = (n choose k) * q^k * (1-q)^(n-k)
Substituting the given values into the formula, we get:
P(X=3) = (15 choose 3) * 0.77^3 * (1-0.77)^(15-3)
P(X=3) = (15!/((15-3)!3!)) * 0.77^3 * 0.23^12

"A certain object's mass is desired to be found after four weighings. If the obtained values are 2.744g, 2.756g, 2.751g, and 2.758g, find the uncertainty in the mass of the object."
In the given problem, by first standard deviation of the four measurements, calculating the the uncertainty in the mass of the object is 0.004582g.
How to Find the Uncertainty?To find the uncertainty in the mass of the object, we need to calculate the standard deviation of the four measurements.
First, we calculate the mean of the four measurements:
mean = (2.744g + 2.756g + 2.751g + 2.758g) / 4 = 2.75225g
Next, we calculate the variance of the measurements:
variance = [(2.744g - 2.75225g)^2 + (2.756g - 2.75225g)^2 + (2.751g - 2.75225g)^2 + (2.758g - 2.75225g)^2] / 3
= 0.000021g^2
The variance is the average of the squared deviations from the mean, divided by the number of measurements minus 1. Note that we use 3 in the denominator, not 4, because we have already used one degree of freedom to calculate the mean.
Finally, we take the square root of the variance to obtain the standard deviation:
standard deviation = sqrt(variance) = 0.004582g
Therefore, the uncertainty in the mass of the object is 0.004582g. We can report the mass as: mass = 2.75225g ± 0.004582g

Over the last year, customers who have phoned their cable company for technical support have had to wait for a customer service representative an average of 28 minutes, with a standard deviation of 5.5 minutes. Company records have shown wait times to be normally distributed. What is the likelihood that a person phones the cable company and waits between 10 to 20 minutes for service?
The probability that a person phones the cable company and waits between 10 to 20 minutes for service is approximately 0.0729, or about 7.29%.
What is the mean and standard deviation?
The standard deviation is a summary measure of the differences of each observation from the mean. If the differences themselves were added up, the positive would exactly balance the negative and so their sum would be zero. Consequently, the squares of the differences are added.
We can start by standardizing the values using the z-score formula:
z = (x - μ) / σ
where:
x = the wait time in minutes
μ = the population mean (average wait time of 28 minutes)
σ = the population standard deviation (5.5 minutes)
For x = 10 minutes:
z = (10 - 28) / 5.5 = -3.27
For x = 20 minutes:
z = (20 - 28) / 5.5 = -1.45
Next, we can use a standard normal distribution table (or a calculator or software) to find the area under the standard normal curve between these two z-scores.
Using a standard normal distribution table, we can find that the area to the left of z = -1.45 is 0.0735, and the area to the left of z = -3.27 is 0.0006. Therefore, the area between z = -3.27 and z = -1.45 is:
0.0735 - 0.0006 = 0.0729
Hence, the probability that a person phones the cable company and waits between 10 to 20 minutes for service is approximately 0.0729, or about 7.29%.

What is intercept?An intercept refers to the point(s) at which a curve or line intersects an axis. For example, the x-intercept is where the line crosses the x-axis, and the y-intercept is where it crosses the y-axis.
What is vertex?A vertex is a point where two or more lines or curves meet. In the context of a parabolic curve, the vertex is the point at which the curve changes direction.
According to the given information:
A. The y-intercept occurs when x=0. Therefore, f(0) = 0² - 4(0) + 4 = 4. So the y-intercept is (0, 4).
The axis of symmetry can be found using the formula x = -b/(2a), where a and b are the coefficients of x² and x, respectively. In this case, a = 1 and b = -4, so x = -(-4)/(2*1) = 2. Therefore, the equation of the axis of symmetry is x = 2.
To find the vertex, we use the fact that the vertex occurs at the axis of symmetry. So when x=2, f(x) = 2² - 4(2) + 4 = -4. Therefore, the vertex is at (2, -4).
B. We can use the vertex to make a table of values:
x f(x)
0 4
1 1
2 0
3 1
4 4
C. We can use the table of values to plot the points and sketch the graph of the function. The graph of the function is a parabola that opens upward, since the coefficient of x² is positive.

Kate watered all the flowers at a business park. While watering, she noticed the daisies had
been planted in groups of 3 and the lilies had been planted in groups of 12. If Kate watered
the same number of each flower, what is the minimum number of each that she must have
watered?
Katemust have watered at least 12 daisies (in groups of 3) and 12 lilies (in groups of 12).
What is the minimum number of each that she must have watered?To determine the minimum number of each flower Kate must have watered, we need to find the least common multiple (LCM) of 3 and 12.
The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...
The multiples of 12 are: 12, 24, 36, 48, 60, ...
We can see that the least common multiple of 3 and 12 is 12, as it is the smallest number that appears in both lists. Therefore, she must have watered at least 12 daisies (in groups of 3) and 12 lilies (in groups of 12).

Step-by-step explanation:
The surface area of a prism can be determined by the formula S = 2B + Ph, where B is
the area of the base, P is the perimeter of the base and h is the height of the prism. How
can this equation be rearranged to solve for the area of the base, B?
the equation rearranged to solve for B is: B = 1/2 * (-S + Ph)
what is equation ?
An equation is a mathematical statement that shows that two expressions are equal. It typically contains one or more variables and can be solved to find the value(s) of the variable(s) that make the equation true.
In the given question,
To solve for the area of the base (B), we need to isolate it on one side of the equation.
First, we can simplify the equation by distributing the 2 to the terms inside the parentheses:
S = 2B + Ph
S = 2B + P * h
Next, we can move the term containing B to the other side of the equation by subtracting 2B from both sides:
S - 2B = P * h
Then, we can isolate B by dividing both sides of the equation by 2:
(S - 2B) / 2 = P * h / 2
Simplifying the right side of the equation:
(S - 2B) / 2 = Ph/2
Finally, we can isolate B by subtracting S/2 and dividing by -1:
(S/2 - Ph/2) = B
Therefore, the equation rearranged to solve for B is:
B = 1/2 * (-S + Ph)

The scatter plot shows the number of households, in millions, that have cable television over eight consecutive years.
Predict the number of households with cable television in year 10.
A) 8.5 million
B) 10.8 million
C) 12.4 million
D) 14.1 milion
In scatter plot, 12 .4 million is the number of households with cable television in year 10.
What is scatter plot?
A scatter plot is a collection of dots that have been plotted along a horizontal and vertical axis. Statistics uses scatter plots because they may display the degree of connection, if any, between the values of observable quantities or events (referred to as variables).
slope = 9 - 5/7 - 1 = 4/6 = 2/3
N - 5 = 2/3 (T - 1 )
N(t) = 2/3 T + 13/3
when t = 11
N(11) = 2/3 * 11 + 13/3
= 35/3
= 12.4
