becca surveyed the students at her school to find out which cellphone company they use. Her results are listed on the table. What is the probability that a randomly chosen student is a junior who uses company B? ​

Answer:

Step-by-step explanation:

Distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

Distance = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]

a). A(-6, -4), B(-3, -1)

Distance between A and B = [tex]\sqrt{(-6+3)^2+(-4+1)^2}[/tex]

                                             = [tex]\sqrt{9+9}[/tex]

                                             = 3√2

                                             = 4.2 units

b). C(3.5, 1), D(-4, 2.5)

Distance between C and D = [tex]\sqrt{(3.5+4)^2+(1-2.5)^2}[/tex]

                                              = [tex]\sqrt{58.5}[/tex]

                                              = 7.65

                                              ≈ 7.7 units

c). Distance between X(5, -5) and Y(-5, 5)

    Distance = [tex]\sqrt{(5+5)^2+(-5-5)^2}[/tex]

                    = [tex]\sqrt{200}[/tex]

                    = 10√2

                    = 14.14

                    ≈ 14.1 units

Answer:

C

Step-by-step explanation:

The mean is essentially the average.

Just add all of them together, and divide by the number of numbers you added.

Answer:

The volume is 64 in³

Step-by-step explanation:

You split the rectangles apart and multiply the length times width times height so I got 32 for both of them and added it to get 64.

Answer:

C

Step-by-step explanation:

Answer:

Step-by-step explanation:

This is an exponential function of the form:

[tex]y=a(1-r)^x[/tex] where a is the initial value and (1 - r) is the growth rate (which in our case is a decay, actually!). Our initial value is 75000 and our rate of change in the population is 15% or .15. Filling in our model:

[tex]y=75000(1-.15)^x[/tex] and simplifying:

[tex]y=75000(.85)^x[/tex] This turns out to be a decay problem because the value inside the parenthesis is less than 100%.

x is our time, so the model is as stated above.

Answer:

[tex]\large\boxed{\tt x = 444.}[/tex]

Step-by-step explanation:

[tex]\textsf{We are asked to solve for x in the given equation.}[/tex]

[tex]\textsf{Note that our goal is to leave x alone on the left side of the equation. In order}[/tex]

[tex]\textsf{to do so we will need to use the \underline{Properties of Equality}.}[/tex]

[tex]\large\underline{\textsf{What are the Properties of Equality?}}[/tex]

[tex]\textsf{Properties of Equality are 9 Properties that allows us to manipulate equations}[/tex]

[tex]\textsf{to, commonly find unknown variables or to determine if equations are true.}[/tex]

[tex]\textsf{For our problem, we will be using 2 out of 9 of these properties as we need to}[/tex]

[tex]\textsf{isolate x, and make sure x is 1x.}[/tex]

[tex]\large\underline{\textsf{Solving for x;}}[/tex]

[tex]\tt \frac{1}{2} x-41=181[/tex]

[tex]\textsf{Let's first use the Addition Property of Equality where the equation will be equal}[/tex]

[tex]\textsf{if we add the same number to both sides of the equation. Let's start by adding}[/tex]

[tex]\textsf{41 to both sides of the equation.}[/tex]

[tex]\tt \frac{1}{2} x-41+41=181+41[/tex]

[tex]\tt \frac{1}{2} x = 222[/tex]

[tex]\textsf{Next, let's use the Multiplication Property of Equality where the equation is}[/tex]

[tex]\textsf{equal if we multiply the same number to both sides of the equation. Let's}[/tex]

[tex]\textsf{multiply 2 to both sides of the equation to cancel out} \ \tt \frac{1}{2} .[/tex]

[tex]\tt 2 \times \frac{1}{2} x = 222 \times 2[/tex]

[tex]\large\boxed{\tt x = 444.}[/tex]

Answer:

5units

Step-by-step explanation:

Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.

Using the formula

D = √(x2-x1)²+(y2-y1)²

D = √(2-2)²+(8-3)²

D = √0+5²

D =  √25

D = 5

Hence the length of the side of the rectangle is 5units

Answer: Ok while i was working out this problem I started by multiplying so i started by 5

2.50 x 5 = 12.5

3.25 x 5 = 16.25 then I added then and got 28.75. So i was like i should go higher. I picked 7.

2.50 x 7 = 17.5

3.25 x 7 = 22. 75 then I added those two and got 40.25 when i got that I was like yes, Im getting closer. So i picked 9 then I got..

2.50 x 9 = 22.5

3.25 x 9 = 29.25 and that equaled 51.75

so then i was like oh! Taxes so I think the answer might be 8. 46 plus tax lol.

HOW DO I ANSWER THIS

Step-by-step explanation:

Answer:

Package of tulip bulbs = $12

Package of crocus = $19

Step-by-step explanation:

Let b = cost of a package of bulbs

     c = cost of a crocus package

Mark:   (1)   9b + c = 127          Huong:  (2)   6b + 6c = 186

                          c = 127 - 9b                        6b + 6(127 - 9b) = 186

                                                                      6b + 762 - 54b = 186

                                                                                      - 48b = -576

                                                                                           b = 12

                          c = 127 -9(12)

                          c = 127 - 108 = 19

Step-by-step explanation:

100% of 60 = 60

100%=60

140% of 60 = x

140%=x

60/x = 100/140

(cross multiplication)

x = 84

140% of 60 = 84

4x+1=6x-29

vvvvvvvvvv

-2x=-30

x=-15

4 x -15= -60

angle 6= 119 degrees
