Answer:

(x + 2)

Step-by-step explanation:

x² - 8x - 20

consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 8)

the factors are - 10 and + 2 , since

- 10 × + 2 = - 20 and - 10 + 2 = - 8 , then

x² - 8x - 20 = (x - 10)(x + 2)

Answer:

Slope-Intercept Form: [tex]y = 2*x -3[/tex]

or

Point-intercept form: [tex]y-(-3)=2(x-0)[/tex]

Step-by-step explanation:

Slope-Intercept Form: [tex]y=mx+b[/tex]

Start from the Y-axis where [tex]b=-3[/tex] then rise/run to the next point. making that our slope.

Point-intercept form: [tex]y-y_0=m(x-x_0)[/tex]

Solve the slope using the two points.

[tex](0,-3)[/tex] and [tex](2,1)[/tex] plug those values into the formula. Make [tex](x,y)=(0,-3)[/tex] and [tex](x_0,y_0)=(2,1)[/tex]

[tex]-3-1=m(0-2)[/tex]

[tex]-4=m(-2)[/tex]

[tex]m=-2[/tex]

[tex]y-(-3)=-2(x-0)[/tex]

To find the average number of pages the student read from day 2 to day 6, add the total pages in these days and divide by 5 days.

This is a very common word used in mathematics and stadistics to refer to the mean value in a set of values.

Add the pages the person read these days and then divide by 5 (total of days).

For example:

35 + 45 + 10 +25 + 20 = 135 / 5 = 27 pages

Note: This question is incomplete because the table is missing; due to this, the answer is based on general knowledge.

Answer:

X = 10

Step-by-step explanation:

Since 2x = 20

we can divide 2 from both sides giving us x = 20/2

Therefore , x = 10 because 20 divided by 2 is 10

Answer:

X= 10

Step-by-step explanation:

2X=20

Then Divide both sides by 2 in order to find the value of X

2X/2=20/2

The Probability of red light is 0.3

P(red) = 0.3

The probability that out of the next eight eastbound cars that arrive randomly at the light, exactly three will be stopped by a red light be 0.25.

P(exactly three get stopped by red light)=0.25

The correct option is (d) P(red)=.3,P(exactly 3 get stopped)=.25

A binomial distribution can be thought of as simply the probability of a SUCCESS or FAILURE outcome in an experiment or survey that is repeated multiple times.

The occurrence,

p= probability of a red light

 =[tex]\frac{15}{15+5+30}[/tex]

 = [tex]\frac{15}{50}[/tex]

 = 0.3

Hence, Probability of getting red light be,

P (red)= 0.3

Now, the Binomial distribution formula,

Probability=( [tex]_r^nC[/tex])[tex]\;p^{r} \;q^{n-r}[/tex]

where, r = number of times for a specific outcome within n trials

[tex]_r^nC[/tex]   = number of combinations

p = probability of success on a single trial

q = probability of failure on a single trial

n = number of trial

According to question,

          = 1- 0.3

          = 0.7

Now using the formula, ( [tex]_r^nC[/tex])[tex]\;p^{r} \;q^{n-r}[/tex]

P( exactly 3  get stopped) = ( [tex]_3^8C[/tex])[tex]\;(0.3)^{3} \;(0.7)^{8-3}[/tex]

                                            = [tex]\frac{8!}{3!(8-3)!}[/tex] [tex](0.027) \; (0.7)^{5}[/tex]

                                           =  [tex]\frac{8!}{3!(5)!}[/tex][tex](0.027) \; (0.16807)[/tex]

                                           = [tex]\frac{8 * 7 * 6 }{3 * 2}[/tex] x 0.027 x 0.16807

                                           = 56 x 0.00453789

                                           = 0.25412184

                                          ≈ 0.25

Hence, Probability of next eight eastbound so that exactly three will stopped by a red light be 0.25.

Answer:

67.5 kg

Step-by-step explanation:

To determine the weight of 45 books, we need to determine the weight of one book, using the equation (30 books = 45 kg). This can be done by dividing 30 to both sides of the equation. Therefore,

We obtained the following equation;

Now, multiply both sides by 45 to determine the weight of 45 books.

Therefore, the weight of 45 books is 67.5 kg.

Answer:

[tex]\huge\boxed{\bf{45books = 67.5kg}} [/tex]

Step-by-step explanation:

Given:-

To find:-

Ans:-

30books = 45kg

45books = y kg

Let's find 45 books (y)

[tex]\sf \to \frac{30}{45} = \frac{45}{y}[/tex]

[tex]\sf \to 45*45 = 30*y[/tex]

[tex]\sf \to 2,025 = 30*y[/tex]

[tex]\sf \to y = \frac{2,025}{30}[/tex]

The relationship between food purchased and food eaten by dogs can be written as, 162 biscuits ≥ 80 biscuits

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.

First, let's calculate the total number of dog biscuits that Jim has bought:

= 6 bags × 27 biscuits per bag

= 162 biscuits

Next, let's calculate how many biscuits the dog will eat in 4 weeks:

= 4 weeks × 5 biscuits per day

= 20 biscuits per week

20 biscuits per week × 4 weeks = 80 biscuits

So, Jim has bought 162 biscuits and his dog will eat 80 biscuits in 4 weeks. This means that Jim has brought enough dog biscuits for his dog for 4 weeks.

162 biscuits ≥ 80 biscuits

What is the dependent variable of an equation?

The dependent variable of an equation is the variable that is completely isolated on one side.

What is the independent variable of an equation?

The independent variable is the variable that is not isolated. The independent variable can either have a cooeficient or has some operation (+ - × ÷) included on that side of the equation.

Determining the independent and dependent variable

In this equation, we can see that "v" is completely isolated on one side and "t" has a cooeficient of 68. Thus, the dependent variable is "v" and the independent variable is "t".
