What is the difference between slope on a table and slope on a graph
Answers
The difference between slope on a table and slope on a graph is shown below:
The slope on a table refers to the rate of change between two points represented in a table of values.
It is calculated by finding the ratio of the change in y-values to the change in x-values between two points.
The slope on a table is determined by taking the difference in y-values and dividing it by the difference in x-values.
On the other hand, the slope on a graph refers to the steepness or incline of a line that connects two points on a graph.
It is calculated by the ratio of the vertical change (rise) to the horizontal change (run) between two points on the graph.
While both the slope on a table and the slope on a graph represent the rate of change, they are determined differently.

Select all ratios equivalent to 20:4
4:20, 2:10, 15:3, 1:2
Answers
Final answer:
The only ratio equivalent to 20:4 from the given choices is 15:3 because, when simplified, both ratios reduce to 5:1.
Explanation:
To determine which ratios are equivalent to 20:4, we need to find ratios that can be simplified or scaled to form the same relationship. An equivalent ratio maintains the proportion when both terms are multiplied or divided by the same number.
First, the given ratio of 20:4 can be simplified by dividing both terms by 4, which gives us 5:1. Now, we can compare this to the choices provided:
4:20 is not equivalent because when simplified (divided by 4), it gives 1:5, which is the inverse of 5:1.2:10 simplifies to 1:5 (dividing by 2), also not equivalent for the same reason.15:3 simplifies to 5:1 (dividing both terms by 3), which is equivalent to 20:4.1:2 is already in simplest form and is not equivalent to 5:1 or 20:4.Therefore, the only ratio equivalent to 20:4 given in the choices is 15:3.

4
are blue. Linda chooses a marble at random, and without putting it back, chooses another one at random. What is the probability that both marbles she chooses are blue? Write your answer as a fraction in simplest form.
Answers
Final answer:
The probability that both marbles chosen by Linda are blue is 2/15, calculated by multiplying the probability of selecting a blue marble on each draw without replacement.
Explanation:
To calculate the probability that Linda selects two blue marbles in a row without replacement, we need to consider the number of blue marbles and the total number of marbles in the bag during each draw. Initially, there are 10 marbles in total with 4 blue marbles. The probability of drawing a blue marble on the first draw is therefore 4/10.
Upon successfully drawing a blue marble the first time, the marble is not replaced, meaning there are now only 9 marbles left with 3 being blue. The probability of drawing a second blue marble is now 3/9, which simplifies to 1/3.
To find the total probability of both events occurring in sequence (both draws resulting in blue marbles), we multiply the probabilities of each individual event occurring:
(4/10) × (3/9) = (2/5) × (1/3) = 2/15.
Therefore, the probability that both marbles Linda chooses are blue is 2/15.

A certain chain of ice cream stores sells 28 different flavors, and a customer can order a single-, double- , or triple-scoop cone. suppose on a multiple-scoop cone that the order of the flavors matter and that the flavors can be repeated.how many possible cones are there? ...?
Answers
There are 22,764 possible cones.
Explanation:To calculate the number of possible cones, we need to consider the number of flavors and the number of scoops. Since a customer can order a single-, double-, or triple-scoop cone, we will consider each case separately.
For a single-scoop cone, the customer can choose one flavor out of the 28 available flavors. Therefore, there are 28 possible single-scoop cones.
For a double-scoop cone, the customer can choose two flavors for the two scoops. Since the order of the flavors matters and repetition is allowed, we can think of this as selecting two flavors with replacement. Using the formula n^r, where n is the number of flavors and r is the number of scoops, there are a total of 28^2 = 784 possible double-scoop cones.
For a triple-scoop cone, the customer can choose three flavors for the three scoops. Again, using the formula n^r, there are a total of 28^3 = 21,952 possible triple-scoop cones.
Therefore, the total number of possible cones is 28 + 784 + 21,952 = 22,764.

Answer: B is on bottom, C is on the left
Step-by-step explanation:
A is on top and B is opposite of A. Therefore, it's on bottom and C is on the left as E is on the right.
The bottom of the rectangular prism is side C, and the left side is side B.

Let's assume that the original piece of paper had the letters A, B, C, D, E, and F on it. After folding, the side with the letter C will be the bottom of the rectangular prism, and the side with the letter B will be on the left. So, the correct answer is A.

PETS Becky wants to buy some fish for her aquarium. She has $20 to spend and the fish cost $2.50 each. Write and solve an inequality to find how many fish Becky can afford.
Answers
The inequality 2.5x ≤ 20 represents the given situation, and Becky can afford at most eight fish.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Let x be the number of fish Becky can afford.
We can write an inequality to represent the situation using the cost of the fish and the amount of money Becky has:
2.5x ≤ 20
To solve this inequality, we'll start by isolating the variable x on one side of the inequality. To do that, we'll divide both sides of the inequality by 2.5:
x ≤ 8
This inequality tells us that Becky can afford at most 8 fish.
To check:
20/2.5 = 8 fish

Consider the surface given by
2x^2+5y^2+z^2=4.
The surface is sliced by planes of the form x=a, y=b or z=c for values of a, b, c given below. How do I match the resulting slices (in other words, the corresponding traces) with their correct plots?
-- Also the slices are:
1. z= 1.5
2. x= 1
3. z=0
4. y=0
Answers
The student can match each slice of the surface 2x^2+5y^2+z^2=4 with its correct plot by substituting the slice values into the equation, resulting in a set of new equations each representing a different conic section centered at the origin.
Explanation:To understand the shapes or plots of the resulting slices when the surface given by 2x^2+5y^2+z^2=4 is sliced by planes of the form x=a, y=b or z=c, you must substitute values of a, b, and c into the equation of the surface to reveal new equations describing the slices.
Let's take z=1.5 as example. Substituting z with 1.5 into the equation, we get 2x^2+5y^2+(1.5)^2=4. This simplifies to 2x^2+5y^2=2.25. This is the equation for an ellipse centered at the origin on the xy plane.Substituting x=1 into the equation gives us 2*(1)^2+5y^2+z^2=4. This simplifies to 5y^2+z^2=2, another ellipse but centered at the origin on yz plane.Substituting z=0, gives us the equation 2x^2+5y^2=4. This is the equation of an ellipse in the xy plane centered at the origin.Finally, substituting y=0 into the equation results in 2x^2+z^2=4. This is the equation of a circle in the xz plane centered at the origin.By comparing these resulting equations with the standard forms of conic sections (circle, ellipse), you can match them with their correct plots.

Below are the choice that can be found from other source:
No; one line has zero slope, the other has no slope.
Yes; the lines are both vertical.
Yes; the lines have equal slopes.
No; the lines have unequal slopes
I think the answer is the first one.
Answer: No, the line through points P(–8, –10) and Q(–5, –12) is not perpendicular to the line through points R(9, –6) and S(17, –5).
Step-by-step explanation:
Two lines are called perpendicular to each other if the product of their slope is -1.
Since, the slope of a line having end points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Thus, the slope of line Joining points P(–8, –10) and Q(–5, –12),
[tex]m_1=\frac{-12+10}{-5+8}=\frac{-2}{3}=-\frac{2}{3}[/tex]
While, The slope of line Joining points R(9, –6) and S(17, –5),
[tex]m_2=\frac{-5+6}{17-9}=\frac{1}{8}[/tex]
Since,
[tex]m_1\times m_2=-\frac{2}{3}\times \frac{1}{8}=-\frac{1}{12}\neq -1[/tex]
Thus, the line through points P(–8, –10) and Q(–5, –12) is not perpendicular to the line through points R(9, –6) and S(17, –5).
