what doe mean (x,y)→(x+2,y-4)
Answer: shift 2 units right, and 4 units down
==================================================
Explanation:
The x+2 means to shift the point 2 units to the right.
For instance, the point (5,13) moves to (7,13) after adding 2 to the x coordinate.
The y-4 means to shift the point 4 units down. Example: (10,8) moves to (10,4) after subtracting 4 from the y coordinate.
Overall, (x,y)→(x+2,y-4) means "shift 2 units right, and 4 units down"
------------
Example:
Let's apply the rule to the point (1, 7)
(x,y)→(x+2,y-4)
(1,7)→(1+2,7-4)
(1,7)→(3,3)
The 4015n printer that is used in most of the labs has a toner cartridge that cost 40.00 and each cartridge should print 10,000 pages, a ream of 500 pages for the printer costs 6.00. Just including those costs how much does it cost to print a single page
Answer:
1 sheet costs 1.6 cents
Step-by-step explanation:
The total cost of the toner is 40 dollars which is good for 10000 pages.
The cost of 500 sheets of paper is 6.00 dollars or 600 cents
500 sheets / 600 cents = 1 sheet /x Cross Multiply
500 sheets x = 600 cents Divide by 500
x = 600/500
x = 1.2 cents.
10000 sheets cost 40 dollars. = 4000 cents
1 sheet costs x
10000/1 = 4000/x Cross multiply
10000*x = 1 * 4000 Divide by 10000
x = 4000/10000
x = 0.4 cents.
Total Cost for 1 sheet = 0.4 cents + 1.2 cents
Total Cost for 1 sheet = 1.6 cents.

The diameter of the sun is about 1. 4x10^6 km. The diameter of the planet Mars is about 7000 km. What is the approximate ratio of the diameter of the sun to the diameter of the mars?
The approximate ratio of the diameter of the Sun to the diameter of Mars is 200. This means that the diameter of the Sun is approximately 200 times larger than the diameter of Mars.
The approximate ratio of the diameter of the Sun to the diameter of Mars can be found by dividing the diameter of the Sun by the diameter of Mars.
Given that the diameter of the Sun is about 1.4x10^6 km and the diameter of Mars is about 7000 km, we can calculate the ratio as follows:
1.4x10^6 km ÷ 7000 km
To divide these values, we can simplify the equation by canceling out the common factor of 1000:
(1.4x10^6 ÷ 1000) km ÷ (7000 ÷ 1000) km
Simplifying further, we have:
1.4x10^3 km ÷ 7 km
Dividing these values gives us:
200 km
Therefore, the approximate ratio of the diameter of the Sun to the diameter of Mars is 200. This means that the diameter of the Sun is approximately 200 times larger than the diameter of Mars.

How to determine the solution to the equationFrom the question, we have the following parameters that can be used in our computation:
2x - 3 = 0
2x - 3 = 3
Also from the question, we understand that the graph is given as
3 = 0
The above equation is false, and cannot be represented on a graph
This is so because 0 and 3 do not have the same value
Similarly, we have 2x - 3 = 0 and 2x - 3 = 3
By substitution, the equations becomes

In preparation for an earnings report, a large retailer wants to estimate p = the proportion of annual sales that occur during the months of November and December. A SRS of sales from last year revealed that 37 of the randomly selected sales occurred during the months of November and December while 124 occurred during the rest of the year.
Calculate a 95% confidence interval for p
Answer:
720 I know this because i did this :)
Step-by-step explanation:
The 95% confidence interval for the proportion p is (0.156, 0.302)
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
To calculate a 95% confidence interval for the proportion p, we can use the following formula:
p ± z√(p(1-p)/n)
where p is the sample proportion (37/161), z is the critical value for a 95% confidence level (1.96 for a large sample size), and n is the sample size (161).
Plugging in these values, we get:
p ± z√(p(1-p)/n)
= 0.229 ± 1.96√((0.229)(0.771)/161)
= 0.229 ± 0.073
Therefore, the 95% confidence interval for p is (0.156, 0.302).

Find the slope of the line that goes through the points (-11, -19) & (-11, -10)
Answer:
The slope is undefinedStep-by-step explanation:
The slope of a line given two points can be found by using the formula
\(m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\\)
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are (-11, -19) & (-11, -10)
The slope is
\(m = \frac{ - 10 - - 19}{ - 11 - - 11} = \frac{ - 10 + 19}{ - 11 + 11} = - \frac{9}{0} \\ \)
Any number divided by zero is undefined so the slope of the line here is undefined.

In statistics, data is a collection of numbers or values that represent a particular phenomenon. One way to measure central tendency, or the typical or representative value of the data, is through the median and the mode.
The median is the middle value when the data is arranged in numerical order, and the mode is the value that appears most frequently.
The third set of data is 24, 25, 25, 25, 26, 26.
The median is the middle value, which is also (25+25)/2 = 25.
The mode is the value that appears most frequently, which is 25.
Therefore, the mode and median are the same, fulfilling Marjane's requirement.
Therefore, the correct option is (c).

find the volume of the solid enclosed by the paraboloid z = 3 x2 (y − 2)2 and the planes z = 1, x = −2, x = 2, y = 0, and y = 2.
The volume of the Solid -
V = ∫[-2,2] 4x^2(2x^2 - 1)(12x^2 - 1) dx
What is volume?
Volume is a measure of the amount of three-dimensional space occupied by an object or a region. It quantifies the extent or size of a solid object or a container. In simpler terms, volume is a measure of how much space an object takes up.
What is integral?
In mathematics, an integral is a fundamental concept in calculus that allows us to compute the total accumulation of a quantity over a given interval. It is used to find the area under a curve, the length of a curve, the volume of a solid, and many other applications.
To find the volume of the solid enclosed by the paraboloid z = 3x^2(y - 2)^2 and the planes z = 1, x = -2, x = 2, y = 0, and y = 2, we need to set up a triple integral over the given region.
The limits of integration for x, y, and z are as follows:
x: -2 to 2
y: 0 to 2
z: 1 to 3x^2(y - 2)^2
The volume V can be calculated as follows:
V = ∫∫∫R dz dy dx
where R represents the region defined by the given planes.
V = ∫∫∫R 3x^2(y - 2)^2 dz dy dx
To evaluate this triple integral, we integrate with respect to z first, then y, and finally x, using the given limits of integration:
V = ∫[-2,2] ∫[0,2] ∫[1,3x^2(y-2)^2] 3x^2(y - 2)^2 dz dy dx
Performing the integration:
V = ∫[-2,2] ∫[0,2] [3x^2(y - 2)^2z]∣[1,3x^2(y-2)^2] dy dx
V = ∫[-2,2] ∫[0,2] 3x^2(y - 2)^2[3x^2(y-2)^2 - 1] dy dx
V = ∫[-2,2] [x^2(y - 2)^2(3x^2(y-2)^2 - 1)]∣[0,2] dx
V = ∫[-2,2] 4x^2(2x^2 - 1)(12x^2 - 1) dx
Evaluate this integral using appropriate techniques or numerical methods, such as numerical integration or computer software, to find the volume of the solid enclosed by the paraboloid and the given planes.

Emily convinced her mom to buy a giant box of her favorite cereal. Her mom doesn't think the box will fit on their shelf. The volume of the box is
The volume of the box is the amount of space that it occupies. The volume can be determined by multiplying the length, width, and height of the box together. It is often measured in cubic units such as cubic meters (m³), cubic centimeters (cm³), or cubic inches (in³). Therefore, the volume of the box cannot be determined without knowing the dimensions of the box.
To determine the volume of the box, we will have to know the dimensions of the box. Once we know the dimensions of the box, we will be able to determine the volume of the box using the formula, volume = length × width × height.
