2. The slope of the graph is 1.5
What is a function?A function is an equation defining the relationship between input and output variables
(A, 2A)
A continuous function is one in which a continuous variation in the input values produces a continuous variation in the output. Therefore, a continuous function does not have discontinuity and it has a defined output within the interval in which it is contagious
A discrete function is one that have input values and output only at specified points, such that the function does not have inputs, and therefore, outputs at certain points.
The points in the scatter plot of the first graph are separate and not linked, such that the function is not contagious between any two x–values, which gives;
The function is a discrete function
The domain, which is the set of possible x–values is; {x| x = -8, -2, 3, 6}
The range is {y|y = 5, 4, -2, 7, }
The line joining the points on the second graph, indicates that the graph has values for all input or x–values
Therefore, the function of the graph is a continuous function
The domain is; -4 < x < ∞The range is 1 ≤ y < 9(A3. A) 1. Points on the graph are:
(0, 2), (2, -1)
The slope is given by the equation;
Slope = ∆y ÷ ∆x
Which gives;
Slope = (-1 - 2)/(2 - 0) = -3/2 = -1.52. The given function is; -3•x + 2•y = -6
To find the slope, the function is expressed in the slope and intercept form, y = m•x + c, as follows;
-3•x + 2•y = -6
2•y = 3•x - 6
Therefore;
2•y = 3•x - 6
y = (3•x - 6) = 1.5•x - 3

We need to know about density to solve this problem. The density of the piece of metal is 5.9 g/[tex]cm^{3}[/tex], so option (c) is the correct answer.
Density is a substance's mass per unit volume. The symbol commonly used for density is ρ. Density can be calculated by dividing the mass by volume. In this question we know that mass of the metal piece is 124 grams and the volume is given to be 21 cubic centimeters. The density can be calculated by dividing the mass by volume of the metal piece.
density =mass/ volume= 124/21=5.90 g/[tex]cm^{3}[/tex]

A plant biologist studies the height of sunflowers. He measures a large sample of sunflowers and creates a probability distribution. The distribution is normal in shape with mean 112 cm and standard deviation 16 cm.
What is the probability (approximately) that a sunflower will be less than 136 cm tall?
Enter a number in decimal form, e.g. 0.68, not 68 or 68%.
The probability that sunflower will be less than 136 cm tall is 0.9332.
How to calculate the probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
From the information, the biologist measures a large sample of sunflowers and creates a probability distribution and the distribution is normal in shape with a mean 112 cm and a standard deviation 16 cm.
It should be noted that the following can be deduced:
Mean = 112
Standard deviation = 16
Sunflower should be less than 136. This will be x < 136.
Therefore, the probability will be;
P(X < 136)
= P(Z < [(number - mean) / standard deviation)]
= P(Z < [136 - 112)/16]
= P(Z < 1.50)
= 0.9332
It should be noted that the probability is gotten by looking at the value of x in the z table.

The reciprocal of 3 7/8 is 8/31.
To find the reciprocal of a number, we invert the fraction by swapping the numerator and denominator.
Let's calculate the reciprocal of 3 7/8.
First, we need to convert the mixed number into an improper fraction. To do this, we multiply the whole number (3) by the denominator (8) and add the numerator (7). This gives us:
3 7/8 = (3 x 8 + 7) / 8 = 31/8
Now, to find the reciprocal, we invert the fraction:
Reciprocal of 31/8 = 8/31

The length of a rectangle is 21 yards. The width of the rectangle is 5 yards. What isthe area of the rectangle?
To find the area of a rectangle, we can use the following formula
[tex]Aread\text{ of a reactangle = \lparen length\rparen}\times\text{ }(width)[/tex]Therefore, to find the total area we have to multiply his length by his width.
Using the data given in the question, we know that the length is 21 yards and the width is 5 yards. Therefore we find that:
[tex]Area\text{ of the rectangle =}(21\text{ yards\rparen}\times\text{ \lparen5 yards\rparen}=105\text{ yards}^2[/tex]we conclude that the area of the rectangle is 105 yards^2.

Shantel told her hired hand Warren to gather eggs from the henhouse. Warren collected 30 eggs and brought them to Shantel. Shantel inspected
them and complained that 40% of them were broken. How many of them were still good eggs?
eggs were still good.
Answer:
18 eggs are still good.
Step-by-step explanation:
If 40% was broken then 60% are still good.
30(.6) = 18
Answer: 18 eggs were not broken and considered good.
Step-by-step explanation: 30 x 40% is the amount of eggs that were broken.
30 x 60% would be the amount of eggs that were still good.
This is becuase the total percentage must add up to be 100% between good eggs and broken eggs.
30 x .60 = 18 So 18 eggs were good
30 x .40 = 12, so that was the number of eggs that were broken
You could have done this problem two ways. Either calculate the broken eggs and subtract from the total. 30-12 = 18, or you could have just calculated the correct amount from figuring the percentage of eggs that were good from the beginning.
1) Is it possible to end up with two different prime factorizations for a number, or will you always end up with the same list of prime factors?
2) What was true about all of the numbers in the final lists of factors? Why?
3) Can two different numbers have the same prime factorization? Why or why not?
4) Explain how writing a number as a product of prime numbers is a way of representing that number.
How does knowing that the prime factorization of 40 is 2 × 2 × 2 × 5 help you know every possible factor of 40?
5) How is what you did in the Action Task related to the colour code in the Minds On Activity?
1) A prime factorization of a particular number will always give the same prime factors.
2) All the factors in the list when multiplied will give the original number.
3) No, two different numbers cannot have the same prime factorization.
4) The prime factors of 40 are 2 and 5.
1) We anticipate finding factors in prime factorization that can add to themselves to get the original number. The original number can be obtained by multiplying the remaining components together as long as the first factor can divide the quantity without leaving a remnant.
Prime factorization of the number, 15 goes thus;
15/3=5
5/5=1
3*5=15
So, all the factors multiply to give the original number.
2) Numbers that split an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal halves.
3) The collection of prime numbers that can be multiplied together to produce a given number is known as the prime factorization of that number. Because the same set of numbers must provide the same result when multiplied together, two separate numbers cannot have the same prime factorization.
4) Any number can be represented as a sum of prime numbers using prime factorization. A number with exactly two elements, 1 and the number itself, is said to be a prime number. As an illustration, the prime factorization of 18 is 2 3 3. Here, the two main elements or prime factors of 18 are 2 and 3.
The prime factorization of 40 is :
40 = 2 × 2 × 2 × 5

The carnival is in town and has a game where players try to throw darts at a rectangular target. The length of the target is 2 centimeters shorter than twice the width. If the perimeter of the target is 20 centimeters, find the dimensions of the target.
The length of the target is 4cm and the width of the target is 6cm.
What are the dimensions of the target?A rectangle is an object that has four sides and four right angles. The sum of angles in a rectangle is 360 degrees. The perimeter of a rectangle is the distance round the rectangle.
Perimeter = 2( length + width)
Length = w - 2 Width = w20 = 2(w - 2 + w)
20 = 2(2w - 2)
20 / 2 = 2w - 2
10 = 2w - 2

What is the slope of a line perpendicular to the line whose equation is 3x-6y=144
Answer: 1/2
Step-by-step explanation:
If we have an equaton in a standard form, that is y = mx + b, our slope is m (the coefficient of x). So, let's transform 3x - 6y = 144 into the standard form.
3x - 6y = 144
-6y = - 3x + 144
y = -3/(-6)x - 144/6
y = (1/2)x - 24
As I mentioned above, the slope is the coefficient of x. Here our slope is 1/2.
