Step-by-step explanation:

Where h is the number of hours Melanie can rent the bike, and the solution is h < 5.5.

Let's first determine the cost of renting a bike for h hours:

Cost = 8h + 6

Since Melanie wants to rent a bike for less than $50, we can set up the following inequality:

8h + 6 < 50

Now we can solve for h:

8h < 44

h < 5.5

Since Melanie cannot rent a bike for a fraction of an hour, the maximum number of hours she can rent the bike is 5 hours.

Therefore, the inequality that will help Melanie find the maximum number of hours she can rent the bike is:

8h + 6 < 50

Where h is the number of hours Melanie can rent the bike, and the solution is h < 5.5.

the value today of the money machine is approximately $29,499.48.

The formula to calculate the present value of an annuity is:

PV = C * (1 - (1 + r)^(-n)) / r

PV is the present value

C is the cash flow per period

r is the interest rate per period

n is the number of periods

Cash flow per year (C) = $4,161.00

Number of years (n) = 23.00

Interest rate (r) = 15.00%

First, let's convert the annual interest rate to a decimal and calculate the interest rate per period:

r = 15.00% / 100 = 0.15

PV = $4,161.00 * (1 - (1 + 0.15)^(-23)) / 0.15

Using a calculator, we find that the present value (PV) is approximately $29,499.48.

In this case, the mean absolute deviation of 8.5 indicates that, on average, the data points deviate from the mean by about 8.5 units.

Mean absolute deviation (MAD) is a statistical measure that represents the average distance between each data point and the mean of the data set. It is calculated by finding the absolute value of the difference between each data point and the mean, and then taking the average of these absolute differences. MAD is a useful measure of the variability or spread of a data set, and is often used as an alternative to the more common measure of standard deviation. Like standard deviation, MAD gives an indication of how spread out the data is, but unlike standard deviation, MAD is less sensitive to extreme values or outliers.

Here,

To find the mean absolute deviation of the data, we first need to calculate the mean (average) of the data:

Mean = (46 + 54 + 43 + 57 + 50 + 62 + 78 + 42) / 8

Mean = 52

The mean of the data is 52.

Next, we need to calculate the absolute deviation of each data point from the mean. The absolute deviation is simply the absolute value of the difference between each data point and the mean:

|46 - 52| = 6

|54 - 52| = 2

|43 - 52| = 9

|57 - 52| = 5

|50 - 52| = 2

|62 - 52| = 10

|78 - 52| = 26

|42 - 52| = 10

Now, we can calculate the mean absolute deviation by taking the average of the absolute deviations:

Mean Absolute Deviation = (6 + 2 + 9 + 5 + 2 + 10 + 26 + 10) / 8

Mean Absolute Deviation = 8.5

The mean absolute deviation of the data is 8.5.

Interpretation: The mean absolute deviation represents the average distance between each data point and the mean of the data. In this case, the mean absolute deviation of 8.5 indicates that, on average, the data points deviate from the mean by about 8.5 units. This means that the data points are relatively spread out, with some points being much higher or lower than the mean.

Step-by-step explanation:

Probabilities

The question describes an event where two counters are taken out of a bag that originally contains 11 counters, 5 of which are white.

Let's call W the event of picking a white counter in any of the two extractions, and N when the counter is not white. The sample space of the random experience is Ω = {WW, W N, NW, N N}

We are required to compute the probability that only one of the counters is white. It means that the favorable options are A = {W N, NW}

Let's calculate both probabilities separately. At first, there are 11 counters, and 5 of them are white. Thus, the probability of picking a white counter is 5/11.

Once a white counter is out, there are only 4 of them and 10 counters in total. The probability to pick a non-white counter is now 6/10.

Thus, the option WN has the probability P(WN) = 5/11 x 6/10 = 30/110 = 3/11

Now for the second option NW. The initial probability to pick a non-white counter is 6/11.

The probability to pick a white counter is 5/10

Thus, the option NW has the probability P(WN) = 6/11 x 5/10 = 30/110 = 3/11

P(A) = 3/11 + 3/11 = 6/11.

Answer:

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. Since the line given in the question is parallel to y = 1/4x + 7, we know that the line has a slope of m = 1/4.

To find the equation of the line that passes through (4,-1), we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1).

Therefore, the equation of the line passing through (4,-1) and parallel to y = 1/4x + 7 is:

y - (-1) = 1/4(x - 4)

y + 1 = 1/4x + 1

This is the equation of a line passing through (4,-1) and parallel to y = 1/4x + 7.

The value of Lambda is 50 units per week, rounded up from the given gross requirements. The EOQ (Economic Order Quantity) is 105 units, rounded up to the next integer.

The fixed time period is 8 units, rounded up to the next integer. The total setup and holding cost is $562, rounded up to the next integer. To determine Lambda, we need to find the maximum gross requirements per week. In this case, the maximum gross requirement is 50 units in Week 1. Therefore, Lambda is 50 units per week, rounded up to the next integer.

The EOQ (Economic Order Quantity) can be calculated using the formula: EOQ = √((2 * Demand * Setup Cost) / Holding Cost). Given the setup cost of $100 and holding cost of $0.50 per unit per week, we can substitute these values along with Lambda into the formula. After calculations, the EOQ is determined to be 105 units, rounded up to the next integer. The fixed time period is the duration between successive orders. In this case, the lead time is 1 week, so the fixed time period would be 8 units (weeks), rounded up to the next integer.

The total setup and holding cost can be calculated by multiplying the setup cost per setup with the number of setups and adding it to the holding cost per unit per week multiplied by the average inventory level. In this scenario, we have one setup in Week 1 and no additional setups. The average inventory level is calculated by summing the scheduled receipts on hand inventory for each week and dividing it by the number of weeks. With these values, the total setup and holding cost is determined to be $562, rounded up to the next integer.
