In the scatter plot, the person with 3 e-mail accounts have 1 credit card.

Typically, the relationship between variables is observed and visually displayed using a scatter plot, a type of chart. Dots are used to indicate the variable values. Scatter plots employ Cartesian coordinates to show the values of the variables in a data set because the placement of the dots on the vertical and horizontal axes will reveal the value of each individual data point. Other names for scatter plots are scattergram, scatter graphs, and scatter charts.

The association between two numerical variables measured for the same individuals is displayed in a scatterplot. The values of one variable are plotted on the horizontal axis, and the values of the other variable are plotted on the vertical axis. On the graph, each individual in the data is represented by a point.

The circumference of the circle is 62.8 feet.

In geometry, the circumference of a circle or ellipse is referred to as its perimeter (from the Latin circumference, meaning "carrying around").

The diameter of the circle = 20 ft

radius (r) = 20 ÷ 2 = 10 ft

Circumference = 2πr = 2 × 3.14 × 10 = 62.8 feet.

For the second problem

The circumference is 17 feet

∴2πr=17

or, 2r = 17 ÷ 3.14 = 5.414... ≈5.41 feet

Hence the diameter is 5.41

Step-by-step explanation:

I'm not 100% sure but that's what I found. also, it says which of the following, so I don't know the answer choices so don't blame me if it's not on the answer choices

Answer: least to greatest:

-26, -1.3, 0, 2.6, 6.5, 12

Step-by-step explanation:

We can start by putting the negative numbers last (-26, -1.3) the greater a negative number is the smaller it actually is! so -26 would be the least followed by -1.3

0 would be after because well it's zero. then we can go least to greatest, 2.6, 6.5, 12.

The radius of the cylinder is 1.49.

What is a cylinder?

A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.

These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis. The perpendicular distance between the bases is the height, “h” and the distance from the axis to the outer surface is the radius “r” of the cylinder.

Volume of the cylinder can be found with the help of the formula

 V = πr²h, where V is the volume of the cylinder, r is the radius and h is the height.

Given,

volume of cylinder = 28

Height of the cylinder = 8

Formula of volume of cylinder is

π[tex]r^{2} h[/tex]= 28

Substitute the values

3.14([tex]r^{2}[/tex])(4)= 28

[tex]r^{2}[/tex] = 28/12.56

[tex]r^{2}[/tex] = 2.22

r = [tex]\sqrt{2.22}[/tex]

r = 1.49

Hence, the radius is given by 1.49 in.

The given inequality is expressed as

10(3x + 2) > 7(2x - 4)

The first step is to open the brackets on each side of the inequality by multiplying the terms outside the bracket by the terms inside. Thus, we have

10 * 3x + 10 * 2 > 7 * 2x - 7 * 4

30x + 20 > 14x - 28

Collecting like terms, we have

30x - 14x > - 28 - 20

16x > - 48

The two equations to set up to solve the absolute value equation given are; 3x - 2 = 19 and 3x - 2 = -19.

The solution of the inequality given; -2|2x+3| + 14 ≥ - 16 is; x ≥ 6 OR x ≤ -9.

It follows from absolute value equations that;

| x | = ±x

Hence, | x | = x OR | x | = -x

Ultimately, the two equations to set up are; 3x - 2 = 19 and 3x - 2 = -19.

2. Also, the equation given; -2|2x+3| + 14≥ - 16 can be solved as follows;

-2|2x+3| ≥ - 16 - 14

-2|2x+3| ≥ - 30

|2x+3| ≥ 15

2x+1 + 2y+1 = 12    The  +1 guarantees that the number is odd. 2x makes any integer even.

Givens

L = 2x + 1

W = 2y + 1

The problem is that you do not have a second equation. So you can just choose.

2x + 1 + 2y + 1 = 12              Combine the left

2x + 2y + 2 = 12                  Subtract 2 from both sides

2x + 2y + 2 - 2 = 12 - 2

2x + 2y = 10

x = 3

y = 2

x = 2

y = 3

L= 3*2 + 1

w = 2*2 + 1

A trigonometric function specifies the relation between two side lengths and an interior angle of a right triangle.

1. The given function is sinθ = -2/3

The definition of sin(θ) is [tex]sin(\theta) = \dfrac{Opposite\ side \ length}{Length \ of \ the \ hypotenuse\ side}[/tex]

From the equation, [tex]sin(\theta) = \dfrac{-2}{3}[/tex], which can be taken as the form, [tex]sin(\theta) = \dfrac{-y}{\sqrt{x^2+y^2} }[/tex], therefore, the opposite side leg, y, will be in the third or fourth quadrant, where the y-value is negative.

The possible graphs are therefore, Graph 2, and Graph 3

2. [tex]sec(\theta) = \dfrac{2}{1}[/tex]

Therefore, [tex]cos(\theta) = \dfrac{1}{2}[/tex]

The definition of cos is [tex]cos(\theta) = \dfrac{Adjacent\ side \ length}{Length \ of \ the \ hypotenuse\ side}[/tex]

Therefore, for the angle in standard position, [tex]cos(\theta) = \dfrac{x}{\sqrt{x^2+y^2} }[/tex]

The adjacent side of the angle is in the positive x-axis, which gives an angle in the Quadrant I or Quadrant IV

The only possible option is graph 3

3. [tex]tan(\theta) = \dfrac{4}{5}[/tex]

The definition of the tangent of an angle is: [tex]tan(\theta) = \dfrac{Opposite\ side \ length}{Length\ of\ the \ Adjacent\ side}=\dfrac{y}{x}[/tex]

Which gives a point at (x, y) or (-x, -y), which are points in Quadrant I and Quadrant III respectively.

The possible solution is therefore graph 3

4. [tex]csc(\theta) = \dfrac{-3}{2}[/tex]

Which gives, [tex]sin(\theta) = \dfrac{-2}{3}[/tex]

Given that the y-value is negative, the possible angle is in Quadrant 3 or 4.

The possible solution is, therefore, graph 2 or 3

5. [tex]cos(\theta) = \dfrac{-3}{5}[/tex]

The x-value is negative; therefore, the angle is in either Quadrant II or Quadrant III

The solution is the graph 1

The boat travels at  18 miles per hour.

What is speed?

Speed is calculated as follows: speed = distance / time. Knowing the units for distance and time is necessary to calculate the units for speed.

The rate at which an object travels a certain distance can be described using the speed formula. The distance that a body travels in a certain amount of time is a common way to measure speed.

Given:  A boat travels 30 miles up the river in the same amount of time it takes to travel 42 miles down the same river. The current is 3 miles per hour.

From the above information we can write,

Let, u is the boat speed in still water, then

[tex]\frac{30}{u-3} = \frac{42}{u+3}[/tex]

Taking cross multiplication,

30(u + 3) = 42(u - 3)

Solving,

30u + 90 = 42u - 126

42u - 30u -126 -90 = 0

12u = 216

u = 18

Therefore, the speed of boat in still water is, 18 miles per hour.
