To graph a point in the cartesian plane you can use rectangular coordinates. These coordinates (in a 2D plane) are given by values of x and y:

So if you want to graph a point, let's say (a,b). You must move "a" steps to the right and "b" steps upwards.

In your exercise, you have to graph the point (5,2), therefore you have to move "5" steps to right and "2" steps upwards:

The perimeter of the rectangle ABCD will be 34 units. Then the correct option is D.

The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be

Perimeter of the rectangle = 2(L + W) units

The coordinates of the rectangle are A(1, 7), B(8, 7), C(8, -3), and D(1, -3).

The distance between AB will be given as,

AB² = (8 - 1)² + (7 - 7)²

AB² = 49

AB = 7 units

The distance between BC will be given as,

BC² = (8 - 8)² + (-3 - 7)²

BC² = 100

BC = 10 units

Then the perimeter of the rectangle will be given as,

P = 2(AB + BC)

P = 2(7 + 10)

P = 2 x 17

P = 34 units

The perimeter of the rectangle ABCD will be 34 units. Then the correct option is D.

Principles in Statitstic Studies

A. Repeated measures design is a research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods.

This is performed in the described study since the same subjects are measured in different periods and in different conditions of weight.

B. Blinding in Statistics. Blinding, or double-blinding, is when a patient does not know what treatment they are receiving so it does not influence the final outcomes. This principle is used here, because none of the participants knew what was given to them.

C. Randomization refers to the practice of using chance methods (random number tables, flipping a coin, etc.) to assign subjects to treatments. We are not sure how the participants were assigned to the specific diet. They were randomly selected. This could refer to randomization.

D. Control refers to directly influency over the conditions of the subject of the study to ensure they all go through the exact same proccesses during the study. We know the groups received different diets in sugar contents, but the rest of their living variables were not controlled, thus this last principle was not used in this study

If this is a linear function between x and y, the slope will be constant.

We can pick any two ordered pairs, like (75, 2.3) and (82, 3) and calculate the slope as:

We can write the point-slope form of the equation and rearrange to find the value of the y-intercept and the slope-intercept form of the equation:

We can test if the equation is correct with another point, like (65,2):

This is not a exact line, so we have to apply a regression model to find the approximate line that best represent this relationship:

Identify the classes and their frequencies

Using the histogram we can find....

60-69 is 2

It wouldn't be option A because you can see the length of the bar is 60 - 70, - 80 - 90 etc...

The answer would be the third option where it gives a accurate descprition of the 7th graders IQ scores where it's rounded to the nearest whole number.

The percentage of students that have a cell phone plan with company Y is:

36 / 120 (total of the surveyed students) *100 = 30%

Then, we use that percentage with the total of the students (380)

30 % of 380

30/100*380

114 (Multiplying)

The answer is the option A.

We would set up the table as shown below

For each cell, we multiply the term for the row by the term for the column. By doing this, the first box is x * x = x^2. The second box is 3 * x = 3x

The third box is x * 2 = 2x

The fourth box is 3 * 2 = 6

By combining them, the equation would be

x^2 + 3x + 2x + 6

= x^2 + 5x + 6

SOLUTION

Looking at the graph, the range is from - 6 on the y-axis and from there going upwards the y-axis. That is y at - 6 to infinity.

Given:

A figure is given with the corresponding angles.

Required:

Choose the correct statement that proves that the lines a and are parallel.

Explanation:

The given angles in the figure are corresponding angles. They are located within the two parallel lines and the transversal line intersecting them.

The corresponding angles are congruent thus lines a and b will be parallel.

Final Answer:

The last option is the correct answer.

In order to find the equation of the perpendicular line. Take into account that the realtion between the slopes of two perpendicular lines is given by:

where m1 and m2 are the slopes of the lines.

The general form of the equation of a line is:

y = mx + b

where m is the slope and b the y-intercept. By comparing the previous equation with the given equation y = 1/3x + 12, you can notice that m=1/3.

If you take this slope as m2, then the slope of the perpendicular line is:

Next, consider that the equation of a line can be also written as follow:

y - yo = m(x - xo)

where (xo,yo) is a point of the line. In this case the point is (-6,-1).

Replace the values of xo, yo and m=m2, into the previous equation and solve for y:

y - (-1) = (-3)(x - (-6))

y + 1 = -3x - 18

y = -3x -19

Hence, the equation of the perpendicular line is y = -3x - 19

We are to find an equivalent fraction to 8/10. But in this case the denominator needs to be 100

This means the multiplying number to the given denominator is 10.

For equivalent fraction, we multiply the numerator and the denominator by the same number

So we would multiply the given numerator too by the multiplying number 10

The equivalent fraction to 8/10 becomes:

Answer:

35 inches on the map will translate to an actual distance of 700 miles (fourth option).

The first step is to determine the scale of the map. In order to determine the scale, divide the actual distance between the two cities by the distance on the map.

Scale = distance between the two cities / distance on the map

Scale = 500 / 25  = 20

Now, multiply the distance on the map by the scale.

Distance in miles = 20 x 35 = 700 miles

Step-by-step explanation:

The question wants us to choose the answer that best completes the visual analogy.

Before we will choose, let's first of all know what visual analogy is is.

Visual analogies are use to determine graphical patterns.

Theses are the ways you can determine a complete image.

When the corresponding shapes are the same , then the transformed shape is a square.

When the corresponding shapes are not the same, the shape at the top top takes precedence over the shape st the bottom.

So, from the above illustrations, the answer that completes the analogy would be the Third image.

In a function, every x-value must be associated with only one y-value.

In the first table, we can see that the x-value x = 1 has two different y-values associated, y = 3 and y = -3. Then, this table doesn't represent a function.

Similarly, in the second table, x = 2 and x = -2 each have two y-values associated, and in the fourth table, x = 4 and x = 4 each have two y-values associated. Therefore, they are not functions.

On the other hand, in the third table, there is only one y-value associated with each x-value. In consequence, it is a function.

x = 23812/15

x = $1587.5

Annual premium = 1587.5 x 12

ANSWER

• x = 8

• y = 10

EXPLANATION

If DEFG is congruent to SPQR, then side QR is congruent to side FG,

Add 4 to both sides of the equation,

And divide both sides by 2,

For the same reason, angles F and Q are congruent,

Replace x by the value we found before,

Subtract 8 from both sides of the equation,

And divide both sides by 6,

Hence, the answers are x = 8 and y = 10.

Notice that the graph passes through the point (-3,0), this means that the function f(x) has a root on x = -3. Then, we can use sintetic division to find the quotient of x+3 with f(x):

In this problem, we have a segment called CD with two endpoints. We know one of the endpoints:

And we don't know the other endpoint, but we know the midpoint:

We will label these known points as the first point (x1,y1) and the midpoint (xm, ym) as follows:

To find the second endpoint which we will call the second point (x2,y2) we use the midpoint formulas:

Solving each equation respectively for x2 and y2:

And substituting the known values for the first point and the midpoint:

We have found the second endpoint (x2,y2):

Step 2. Once we know the two endpoints of the segment CD:

We make a graph for reference:
