The equation of the line that is parallel to k and passes through (-1, 3) is
- x + 2y = 7
How to find the equation of a line?The equation of a line can be represented in different form such as point slope form, slope intercept form and standard form.
Therefore, the equation of the line is parallel to k.
Parallel line shave the same slope.
Therefore, let's find the slope of k to find the slope of the equation of the line.
Hence, using (7, 2)(1, -1)
m = -1 - 2 / 1 - 7
m = - 3 / -6
m = 1/ 2
Therefore, the slope of the line is 1 / 2. Let's find the y-intercept using the point (-1, 3)
3 = 1 / 2(-1) + b
3 = - 1 / 2 + b
b = 3 + 1 / 2
b = 7 / 2
Hence, the equation is as follows;
y = 1 /2x + 7 / 2
2y = x + 7
2y - x = 7
- x + 2y = 7

Answers
The table has a greater rate of change.
The rates of change are equal.
In the given problem, we have a table showing the relationship between x and y values. By comparing the change in y with the change in x, we can determine the rate of change. Looking at the table, we observe that for every increase of 1 in x, there is a corresponding increase of 1 in y. Therefore, the rate of change for this table is 1.
The slopes are equal.
The equation has a greater slope.
In problem 2, we are given a linear equation in the form y = mx + b, where m represents the slope. The given equation is y = 2x + 7, which means the slope is 2. To compare the rates of change, we compare the slopes. If the slopes are equal, the rates of change are equal. In this case, the slopes are equal to 2, so the rates of change are the same.
The function rule has a greater slope.
The slopes are equal.
In problem 3, we are told that as x increases by 1, y increases by 3. This information gives us the rate of change between x and y. The slope of a function represents the rate of change, and in this case, the slope is 3. Comparing the slopes, we find that they are equal, as both have a value of 3. Therefore, the rates of change are the same.

total of $314 this week, how many hours did she work at Pizza Place?
Answers
$314-$80=$234
And then divide that total by how much she gets each hour
$234/$9=26
So you get the answer of 26 hours she worked at the pizza place
Number of hours Marissa worked at pizza place is 26 hours.
What is simplification?Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus.

Answers
Therefore, y is equal to 12 2/5 and n is equal to 2 2/5 in the equation.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. An equation is typically written with an equal sign (=) between two expressions. Equations can involve various mathematical operations, such as addition, subtraction, multiplication, division, exponents, and logarithms. Solving an equation typically involves performing mathematical operations on both sides of the equation to isolate the variable (the unknown value) and find its value.
Here,
To solve for y in the equation 2y + 8 1/5 = 33, we can follow these steps:
Subtract 8 1/5 from both sides of the equation:
2y = 33 - 8 1/5
2y = 24 4/5
Divide both sides of the equation by 2:
y = (24 4/5) / 2
y = 12 2/5
Therefore, y is equal to 12 2/5.
To solve for n in the equation 2n + 4 1/5 = 9, we can follow these steps:
Subtract 4 1/5 from both sides of the equation:
2n = 9 - 4 1/5
2n = 4 4/5
Divide both sides of the equation by 2:
n = (4 4/5) / 2
n = 2 2/5
Therefore, n is equal to 2 2/5.

what are the conditions for using the normal approximation for a sampling distribution of proportions g
Answers
The normal approximation for sampling distributions of proportions can be used when the sample size is large enough.
What prerequisites must be met for a sampling distribution of proportions g in order to use the normal approximation?The conditions for using the normal approximation for a sampling distribution of proportions are as follows: The sample size (n) must be sufficiently large (usually 30 or more). The sample proportion (p) should not be close to 0 or 1. The population distribution should be normally distributed.The general rule is that if the sample size (n) is greater than or equal to 30, then the normal approximation can be used. When using the normal approximation for a sampling distribution of proportions, the sample size must be greater than or equal to 30 and the population proportion (p) must be between 5% and 95%. Furthermore, the sample size must be large enough that the expected number of successes (np) and expected number of failures (nq) are both greater than or equal to 10. Finally, the sampling distribution should be approximately normal and the sample should be randomly selected from the population. The normal approximation is a useful tool for estimating confidence intervals and the probability of extreme values, as well as for hypothesis testing. It can be used to estimate the probability of success in a given sample of proportions, which can be helpful when making decisions about a population or understanding the behavior of a system.To learn more about distribution of proportions refer to:

two numbers, x and y, are selected at random from the interval [0,2] . what is the probability that y
Answers
The Probability that y is greater than x in the interval [0, 2] when two numbers, x and y, are selected at random is 0.5.
To find the Probability:
The possible pairs of numbers that can be selected from the interval [0,2] are (0,0), (0,1), (0,2), (1,0), (1,1), (1,2), (2,0), (2,1), and (2,2).
Out of these nine possible pairs, only five pairs have y greater than or equal to x.(0,0), (1,0), (1,1), (2,0), and (2,1)
Since the two numbers are selected randomly, each of the nine possible pairs is equally likely to occur.
Therefore, the probability that y is greater than x in the interval [0,2] when two numbers, x and y, are selected at random is:
P(y ≥ x) = favorable outcomes/total outcomes= 5/9= 0.5
Thus, the probability that y is greater than x in the interval [0,2] when two numbers, x and y, are selected at random is 0.5.

In 2020, a total of 9559 Nissan Leafs were sold in the US. For the 12-month period starting January 2020 and ending December 2020, the detailed sales numbers are as follows: 651, 808, 514, 174, 435, 426, 687, 582, 662, 1551, 1295 and 1774 units.
before the Nissan plant in Smyrna, Tennessee, started to produce the Nissan Leaf they were imported from Japan. Although cars are now assembled in the US, some components still imported from Japan. Assume that the lead time from Japan is one weeks for shipping. Recall that the critical electrode material is imported from Japan. Each battery pack consists of 48 modules and each module contains four cells, for a total of 192 cells. Assume that each "unit" (= the amount required for an individual cell in the battery pack) has a value of $3 and an associated carrying cost of 30%. Moreover, assume that Nissan is responsible for holding the inventory since the units are shipped from Japan. We suppose that placing an order costs $500. Assume that Nissan wants to provide a 99.9% service level for its assembly plant because any missing components will force the assembly lines to come to a halt. Use the 2020 demand observations to estimate the annual demand distribution assuming demand for Nissan Leafs is normally distributed. For simplicity, assume there are 360 days per year, 30 days per month, and 7 days per week.
(a) What is the optimal order quantity?
(b) What is the approximate time between orders?
Answers
(a)The optimal order quantity is 4609 units.
(b)The time between orders is 1.98 months.
To determine the optimal order quantity and the approximate time between orders, the Economic Order Quantity (EOQ) model. The EOQ model minimizes the total cost of inventory by balancing ordering costs and carrying costs.
Optimal Order Quantity:
The formula for the EOQ is given by:
EOQ = √[(2DS) / H]
Where:
D = Annual demand
S = Cost per order
H = Holding cost per unit per year
calculate the annual demand (D) using the 2020
sales numbers provided:
D = 651 + 808 + 514 + 174 + 435 + 426 + 687 + 582 + 662 + 1551 + 1295 + 1774
= 9559 units
To calculate the cost per order (S) and the holding cost per unit per year (H).
The cost per order (S) is given as $500.
The holding cost per unit per year (H) calculated as follows:
H = Carrying cost percentage × Unit value
= 0.30 × $3
= $0.90
substitute these values into the EOQ formula:
EOQ = √[(2 × 9559 × $500) / $0.90]
= √[19118000 / $0.90]
≈ √21242222.22
≈ 4608.71
Approximate Time Between Orders:
To calculate the approximate time between orders, we'll divide the total number of working days in a year by the number of orders per year.
Assuming 360 days in a year and a lead time of 1 week (7 days) for shipping, we have:
Working days in a year = 360 - 7 = 353 days
Approximate time between orders = Working days in a year / Number of orders per year
= 353 / (9559 / 4609)
= 0.165 years
Converting this time to months:
Approximate time between orders (months) = 0.165 × 12
= 1.98 months

Normal probability distribution is applied to: A. a subjective random variable B. a discrete random variable C. any random variable D. a continuous random variable
Answers
Normal probability distribution is applied to a continuous random variable. The correct option is D.
The normal probability distribution, also known as the Gaussian distribution, is a probability distribution that is commonly used in statistics and probability theory. It is a continuous probability distribution that is often used to model the behavior of a wide range of variables, such as physical measurements like height, weight, and temperature.
The normal distribution is characterized by two parameters: the mean (μ) and the standard deviation (σ). It is a bell-shaped curve that is symmetrical around the mean, with the highest point of the curve being located at the mean. The standard deviation determines the width of the curve, and 68% of the data falls within one standard deviation of the mean, while 95% falls within two standard deviations.
The normal distribution is widely used in statistical inference and hypothesis testing, as many test statistics are approximately normally distributed under certain conditions. It is also used in modeling various phenomena, including financial markets, population growth, and natural phenomena like earthquakes and weather patterns.
Overall, the normal probability distribution is a powerful tool for modeling and analyzing a wide range of continuous random variables in a variety of fields.
