Match the "numbers" with the correct corresponding "letter". For example the graph y 3 N 4 1 2z+1 is a liner graph therefore 1 matches with A.
Answers
The graph names are matched with the corresponding numbers as follows: 1 corresponds to linear graph (A), 2 corresponds to hyperbola (D), 3 corresponds to ellipse (C), and 4 corresponds to parabola (B).
The given graph equations can be analyzed to determine their shapes and corresponding names.
1. The equation y = 2r + 1 represents a linear graph, where the variable r has a coefficient of 2 and there is no squared term present.
2. The equation x² - y² = 1 represents a hyperbola, as it involves the difference of two squared terms.
3. The equation 2 = 0 is a contradiction, as it states that 2 is equal to 0, which is not possible. Therefore, it does not correspond to any specific graph.
4. The equation 2r + y = 4 represents a linear graph, similar to equation 1, with the variables r and y having coefficients.
By matching the numbers with the corresponding lettered graph names, we find that 1 corresponds to linear graph (A), 2 corresponds to hyperbola (D), 3 corresponds to ellipse (C), and 4 corresponds to parabola (B).

It says here to use the information to write a standard form equation of this circle and I can’t find any answer
1) Center: (2, 4)
Radius: V215
Answers
The standard form of the equation of a circle is (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius.
Using this formula, we can write the equation of the circle with center (2, 4) and radius √215 as follows:(x - 2)² + (y - 4)² = (√215)²
Simplifying this equation, we get:(x - 2)² + (y - 4)² = 215
Thus, the standard form equation of this circle is (x - 2)² + (y - 4)² = 215.
The center of the circle is (2, 4) and the radius is √215.
To write the standard form equation of the circle, we use the formula (x - h)² + (y - k)² = r².
Plugging in the values of the center and radius, we get the equation (x - 2)² + (y - 4)² = 215.
What is Standard Form means?
Standard form refers to a specific way of writing mathematical equations, typically used in algebra. It involves representing an equation as a linear combination of variables and constants, where the variables are raised to the power of one and the coefficients are integers.

If an explanatory variable is exogenous it implies that: a. the variable cannot be correlated with other explanatory variables. b. the variable is not correlated with the regression error. c. the variable must have zero mean. d. the value of the variable must be randomly assigned.
Answers
b. the variable is not correlated with the regression error. if an explanatory variable is exogenous, it means that the variable is not correlated with the regression error term. This assumption is important for obtaining unbiased and consistent parameter estimates in regression analysis.
If an explanatory variable is exogenous, it implies that the variable is not correlated with the regression error term. In other words, the exogenous variable is unrelated to the factors that are not explicitly included in the regression model and captured by the error term.
Exogeneity is an important assumption in regression analysis, as violating this assumption can lead to biased and inconsistent parameter estimates. When an explanatory variable is exogenous, it means that its value is determined independently of the other variables in the model and the error term.
Let's briefly discuss the other options:
a. The variable cannot be correlated with other explanatory variables: Exogeneity does not necessarily imply that the variable cannot be correlated with other explanatory variables. Explanatory variables can be correlated with each other as long as they are not correlated with the regression error term.
c. The variable must have zero mean: Exogeneity does not require that the variable has a zero mean. Exogeneity refers to the lack of correlation between the variable and the regression error, not its mean value.
d. The value of the variable must be randomly assigned: Exogeneity does not require that the value of the variable is randomly assigned. Exogeneity implies that the variable is not affected by the regression error and is determined independently of the other variables in the model, but it does not necessarily imply a random assignment of values.
In summary, if an explanatory variable is exogenous, it means that the variable is not correlated with the regression error term. This assumption is important for obtaining unbiased and consistent parameter estimates in regression analysis.

Over the last ten years a compary/s annual earnings increased year over year six (not seven) times and decreased four times. You decide to model the number of earnings increases for the next decade as a binomial random variable. Define success as an increase in annual eamings. Crease an estimate of the probability of success and assume that your eatimate of the probebility of success is the actual probabilisy of success. What is the probabilty that eamings will increase in exactly four (not five) of the next ten years? Give your answer as a probability rounded to three docimal places, so in the format 0××O.
Answers
From the given problem, we can say that the model of the number of earning increases in the next decade is a binomial random variable. Here, success is defined as an increase in annual earnings. We have to estimate the probability of success and assume that the estimated probability of success is the actual probability of success.
We need to find the probability that earnings will increase in exactly four of the next ten years. According to the given problem, we can say that the probability of earning increases is represented as a binomial distribution. A binomial distribution is used to model the number of successes in a given number of trials. It is used when there are two possible outcomes, success or failure, in each trial. It is the probability distribution of the number of successes in a fixed number of independent trials with only two possible outcomes.Success is defined as an increase in annual earnings. So, the probability of success can be represented as p and the probability of failure can be represented as q. Therefore, q = 1 - p. The binomial distribution can be written as:P(x) = nCx * px * (1 - p)^(n - x)Here, nCx represents the number of ways of choosing x successes from n trials. px represents the probability of x successes in n trials. (1 - p)^(n - x) represents the probability of (n - x) failures in n trials.Now, we can use the formula of binomial probability distribution to calculate the probability of earning increases in exactly four of the next ten years. We have to find the value of P(x = 4) for n = 10, p = 6/10 = 0.6, and q = 1 - p = 1 - 0.6 = 0.4.P(x = 4) = 10C4 * (0.6)^4 * (0.4)^6P(x = 4) = 210 * 0.1296 * 0.16777P(x = 4) = 0.02938So, the probability of earnings increasing in exactly four of the next ten years is 0.02938.
The probability of earnings increasing in exactly four of the next ten years is 0.02938.

How many observations should a time study analyst plan for in an operation that has a standard deviation of 1.5 minutes per piece if the goal is to estimate the mean time per piece to within .4 minute with a confidence of 95.5 percent? (Do not round intermediate calculations. Round up your final answer to the next whole number.)
Number of observations
Answers
The time study analyst should account for at least 55 observations in order to calculate the mean time per item with a 95.5% confidence level and a 0.4 minute margin of error.
We can use the sample size calculation formula in a confidence interval to get the number of observations required for a time study with the specified parameters:
[tex]n = (Z * \sigma / E)^2[/tex]
Where:
n = sample size
Z = The target confidence level's Z-score (95.5% translates to roughly 1.96)
σ = procedure standard variation (1.5 minutes per piece)
E = margin of error (0.4 minutes)
Plugging in the values, we can calculate the sample size:
[tex]n = (1.96 * 1.5 / 0.4)^2[/tex]
[tex]n = (2.94 / 0.4)^2[/tex]
[tex]n = 7.35^2[/tex]
n ≈ 54.02
We round up the sample size to the next whole number because we can't have a portion of an observation:
n = 55
Therefore, the time study analyst should prepare for at least 55 observations to estimate the mean time per item with a margin of error of 0.4 minutes and a confidence level of 95.5%.

Problem 2(2×10=20 pts ) A car repair shop has two hoists where cars can be lifted for repair work. Currently customers leave the shop (after finishing their repairs) at a rate of 4 per hour. On average 8 cars are waiting to be processed. a. On the average, how long do customers wait before being processed? b. Some of the customers need routine repairs and others need major repairs. The repair shop owner feels that he is losing many customers needing routine repair because of the long wait and, therefore, dedicates one hoist for routine repair and one for major repairs. A study indicates that the throughput rate for routine repairs is 3 per hour and the throughput rate for major repairs is 1 per hour. On the average 5 people are waiting for routine repairs and 3 on average are waiting for major repairs. Given these assumptions, how long does each type of customer now wait before being served?
Answers
On average, customers needing routine repairs wait for 1.67 hours, while customers needing major repairs wait for 2.5 hours before being served.
Let's consider the average number of customers waiting and the throughput rates for routine repairs and major repairs. With one hoist dedicated to routine repairs and one hoist dedicated to major repairs, the throughput rate for routine repairs is 3 cars per hour, and the throughput rate for major repairs is 1 car per hour. The average number of customers waiting for routine repairs is 5, and the average number of customers waiting for major repairs is 3. Using Little's Law, which states that the average number of customers in a system is equal to the arrival rate multiplied by the average time spent in the system, we can calculate the average waiting time for each type of customer. For routine repairs, the arrival rate is 3 cars per hour, and the average number of customers waiting is 5. Therefore, the average waiting time for routine repairs is 5/3 = 1.67 hours. Similarly, for major repairs, the arrival rate is 1 car per hour, and the average number of customers waiting is 3. Therefore, the average waiting time for major repairs is 3/1 = 3 hours. By dedicating one hoist to routine repairs and one hoist to major repairs, the average waiting time for routine repairs is reduced compared to the previous scenario when all repairs were done on a first-come, first-served basis. However, the waiting time for major repairs has increased due to the lower throughput rate for major repairs compared to routine repairs.
