Answer:

Step-by-step explanation:

What are the Factors of 20

Factors of 20 =1, 2, 4, 5, 10, 20

Distinct Factors of 20 = 1, 2, 4, 5, 10, 20,

Note: Factors of 20 and Distinct factors are the same.

Factors of -20 = -1, -2, -4, -5, -10, -20,

What are the Factors of 23

Factors of 23 =1, 23

Distinct Factors of 23 = 1, 2, 4, 5, 10, 20, 1, 23,

Note: Factors of 23 and Distinct factors are the same.

Factors of -23 = -1, -2, -4, -5, -10, -20, -1, -23,

Negative factors are just factors with negative sign.

How to calculate factors of 20 and 23

The factors are numbers that can divide 23 without remainder.

Every number is divisible by itself and 1.

Factors of 20

20/1 = 20         gives remainder 0 and so are divisible by 1

20/2 = 10         gives remainder 0 and so are divisible by 2

20/4 = 5         gives remainder 0 and so are divisible by 4

20/5 = 4         gives remainder 0 and so are divisible by 5

20/10 = 2         gives remainder 0 and so are divisible by 10

20/20 = 1         gives remainder 0 and so are divisible by 20

Factors of 23

23/1 = 23         gives remainder 0 and so are divisible by 1

23/23 = 1         gives remainder 0 and so are divisible by 23

20,23

 

The real common factors of 20,23 is 1

LCM of 20 and 23

Multiples of 20= 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400,

Multiples of 23= 23, 46, 69, 92, 115, 138, 161, 184, 207, 230, 253, 276, 299, 322, 345, 368, 391, 414, 437,

Least common multiple (LCM) of 20 and 23= 460

HCF of 20 and 23

Highest common factor (HCF) is calculated using real common factors above

HCF of 20 and 23 = 1

GCF of 20 and 23

Greatest common factor (GCF) is the same as Highest common factor (HCF)

GCF of 20 and 23 = 1

LCD of 20 and 23

lowest common Denominator (LCD) is the same as Least common multiple (LCM)

lowest common Denominator (LCD) of 20 and 23= 460

We get factors of 20,23 numbers by finding numbers that can divide 20,23 without remainder or alternatively numbers that can multiply together to equal the target number being converted.

In considering numbers than can divide 20,23 without remainders. So we start with 1, then check 2,3,4,5,6,7,8,9, etc and 20,23

Getting factors is done by dividing 20,23 with numbers lower to it in value to find the one that will not leave remainder. Numbers that divide without remainders are the factors.

Factors are whole numbers or integers that are multiplied together to produce a given number. The integers or whole numbers multiplied are factors of the given number. If x multiplied by y = z then x and y are factors of z.

if for instance you want to find the factors of 20. You will have to find combination of numbers that when it is multiplied together will give 20. Example here is 5 and 4 because when you multiplied them, it will give you 20. so they are factors of the given number 20. Also 1 and 20, 2 and 10 are factors of 20 because 1 x 20 = 20 and 2 x 10 = 20. The factors of the given interger number 20 are 1, 2, 4, 5, 10, 20

To calculate factors using this tool, you will enter positive integers, because the calculator will only allow positive values, to calculate factors of a number. if you need to calculate negative numbers, you enter the positive value, get the factors and duplicate the answer yourself with all the give positive factors as negatives like as -5 and -6 as factors of number 30. On the other hand this calculator will give you both negative factors and positive integers for numbers. For instance, -2 , -3,-4 etc.

factors is like division in maths, because it gives all numbers that divide evenly into a number with no remainder. example is number 8. it is is evenly divisible by 2 and 4, which means that both 2 and 4 are factors of number 10.

79-81 thank you so much!!
Novosadov [1.4K]
79.(b)this is because you have six choices, 3 red, 1 blue, 1 yellow, and 1 green and since it says not red you only have 3 choices, blue yellow and green, so the fraction would be 3/6. You can simplify the fraction by dividing it by 2 and you would get 1/2.

80.the answer will still be (b) which is the same explanation for 79.

81. (C) because remember that the first time you only had a 50% (1/2) chance of getting red and the second chance of getting a red will be the same but not
Its not likely You can get a red.

andreev551 [17]

Answer:

(b) H0: p = 0.5; Ha: p > 0.5

Step-by-step explanation:

p represents the population proportion.

A null hypothesis is a statement from the population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.

An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.

What is the equation of the graphed linear model?<br><br><br><br> y = <br> x +
timofeeve [1]

Answer:

y = - 2x + 110

Step-by-step explanation:

The equation of a line in slope- intercept form is

y + mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 110) and (x₂, y₂ ) = (20, 70) ← 2 points on the line

m = \frac{70-110}{20-0} = \frac{-40}{20} = - 2

the line crosses the y- axis at (0, 110) ⇒ c = 110

y = - 2x + 110 ← equation of line
