If a newspaper costs $0.60 and you only have $5.00 in quarters, how many cents would you lose out on because the vending machine doesn't give back any change?

Answer:

y=1/5 x -4

Step-by-step explanation:

Basically, we first start with perpendicular. Note that 2 lines' that are perpendicular have product = -1. Thus, the slope of the line (in question) is 1/5.

Now, we know y = mx + b by slope intercept. Note that y intercept means (0,-4). Thus, plugging in give the answer.

The statistical method that would be best to use in this situation is b) Regression analysis.

Regression analysis is a statistical technique used to examine the relationship between a dependent variable (in this case, the number of students registering each semester) and one or more independent variables (such as time, semester, or any other relevant factors). By analyzing past data on the number of students registering each semester, regression analysis can help identify trends, patterns, and the average number of students registering.

Using regression analysis, the university can estimate the average number of students registering each semester based on historical data and use this information to plan how many classes to run in the upcoming semester. It allows for a quantitative analysis and prediction based on the relationship between variables, making it a suitable choice for estimating the average number of students in this scenario.

Hence the answer is Regression analysis.

Answer:-220

Step-by-step explanation:

As per the concept of triangle, Adjacent angles are the one which has two angles that lie in the same plane and have a common vertex and a common side but have no common interior points.

In math, Angles are formed when two lines intersect.

Here they are measured as a rotation from one side to the other.

And for the convention, the measurement of angles in a plane is considered positive when the rotation is counter-clockwise and is negative when the rotation is clockwise.

Here we need to find the  two angles that lie in the same plane and have a common vertex and a common side but have no common interior points.

While we looking into the given question, we know that two angles sharing a common vertex and a side but no common interior points are called adjacent angles.

Therefore, Adjacent angles can be formed when dividing a bigger angle into several smaller parts, thus introducing common rays between the angles.

The solution of the system of equations from the graph is x = 2.

The point of intersection formula is used to determine where two lines meet, or the point at which they intersect. In Euclidean geometry, the intersection of two lines can be either an empty set, a point, or a line. Two lines must meet certain requirements in order to intersect, including being in the same plane and not being skew lines. The intersection of these lines may be determined using the intersection formula.

The solution of the system of equations can be determined from the graph by determining the point of intersection between the two lines.

From the graph we observe that the point of intersection of the two lines is at (0, 2).

Hence, the solution of the system of equations is x = 2.

Surface area of the triangular prism which is a compound shape has an area of: 878mm².

The combined area of one or more circles and simple polygons is known as the area of the composite forms. The areas of every basic shape can be added together to determine the area of the composite shapes. Simply calculate each shape's area separately, then put them together to get the area of composite shapes.

Now in the question, we have 2 triangles with base, b =31mm and height, h = 14mm

Now area of both the triangles = 2 × 1/2 × b × h

= 2×1/2×14×31

=434mm²

Now we have three different rectangles.

In the first rectangle, length, l = 27mm and breadth, b = 6mm

Area of the rectangle as we know = l × b

= 27 × 6

= 162mm²

In the second rectangle, l = 16mm and b = 6mm

Area = 16 × 6

= 96mm²

In the final rectangle, l = 31mm and b = 6mm

Area = 31 × 6

Step-by-step explanation:

The required fuel for the nighttime trip is approximately 5,610 gallons.

To calculate the required fuel for the nighttime trip, we need to consider the distance of the trip, the aircraft's airspeed, the fuel consumption rate, and the effect of the tailwind.

Given that the trip is 2,425 miles and the aircraft's airspeed is 570 miles per hour, we can determine the total flight time by dividing the distance by the airspeed. In this case, the flight time is approximately 4.25 hours.

Next, we need to account for the fuel consumption rate. The aircraft burns 3,000 gallons of fuel per hour. Multiplying the flight time by the fuel consumption rate gives us the total fuel consumed during the trip, which is approximately 12,750 gallons.

Now, let's factor in the effect of the tailwind. The tailwind of 32 miles per hour will increase the groundspeed of the aircraft. To calculate the groundspeed, we subtract the tailwind speed from the airspeed. In this case, the groundspeed is 570 - 32 = 538 miles per hour.

To determine the fuel consumption adjusted for the groundspeed, we divide the distance of the trip by the groundspeed. This gives us the adjusted flight time of approximately 4.51 hours. Multiplying the adjusted flight time by the fuel consumption rate gives us the fuel consumption adjusted for the tailwind, which is approximately 13,530 gallons.

Therefore, the required fuel for the nighttime trip is approximately 5,610 gallons (13,530 - 12,750).

456,976,000 possible passwords

Step-by-step explanation:

To calculate the number of possible passwords, we need to figure out how many options we have for each character slot in the password.

For the first three slots, we need to choose a digit from 0 to 9. This means we have 10 options for each slot, since there are 10 digits to choose from. Since there are three slots for digits, the number of possible combinations for the first three characters is 10 x 10 x 10 = 1000.

For the next four slots, we need to choose a letter from A to Z. There are 26 letters in the alphabet, so we have 26 options for each slot. Since there are four slots for letters, the number of possible combinations for the last four characters is 26 x 26 x 26 x 26 = 456,976.

To find the total number of possible passwords, we simply multiply the number of combinations for the first three characters by the number of combinations for the last four characters:

1000 x 456,976 = 456,976,000

Therefore, there are 456,976,000 possible passwords that can be made for this website.

To calculate the covariance and correlation coefficient of U and V, we need to first find the expected value and variance of U and V.

The covariance of two variables is a gauge of their relationship. In other words, it is a measure of how much the values of two variables tend to fluctuate together. Positive covariance shows that the values of the two variables tend to rise or decrease together, whereas negative covariance indicates that the values of one variable tend to increase when the values of the other variable drop. In probability theory and statistics, covariance is frequently employed to determine the association between two variables. It is determined by multiplying the variances of the two variables from their respective means and dividing the result by the total number of observations. This metric can be helpful for seeing trends and patterns in data and aiding analysts in forecasting.

How to solve?

The expected value of U is $E[U] = E[2 - X_1 - 2X_2] = 2 - m - 2m = -2m. Similarly, the expected value of V is $E[V] = E[3 + 3X_2 - X_3] = 3 + 3m - m = 4m.

A measure of the link between two random variables and how much they fluctuate together is called covariance. Alternately, we may say that it establishes the relationship between the two variables' changes, i.e., that a change in one variable is equivalent to a change in the other.

When one variable changes, covariance shows the link between the other two variables. Both variables are said to have positive covariance if a rise in one causes an increase in the other. Reduced values of one variable also result in reduced values of the other.

for expected value of U ;

Answer:

Darlene's net proceeds after the broker fees are taken out is $8,279.

Step-by-step explanation:

From the question, the following can be obtained:

Basic cost of purchase of the stock = $20,000

Broker fee related to purchase = Basic cost of purchase of the stock * 1.5% = $20,000 * 1.5% = 300

Total cost of purchase of the stock = Basic cost of purchase of the stock + Broker fee related to purchase = $20,000 + 300 = $20,300

Selling price = $28,600

Broker fees related sales = 21

The net proceed can therefore be calculated as follows:

Net proceeds = Selling price - Broker fees related sales - Total cost of purchase of the stock  = $28,600 - $21 - $20,300 = $8,279

Therefore, Darlene's net proceeds after the broker fees are taken out is $8,279.
