Answer: The second graph, counting from the top.

Step-by-step explanation:

We have inequality:

-2r + 3 ≥ 19

We can isolate r in this inequality, and get:

-2r ≥ 19 - 3 = 16

-r ≥ 16/2 = 8

Now we change the sign, this also changes the direction of the greater or equal than a sign:

r ≤ -8

So we will have that our graph must start at r = -8, and include all the numbers that are smaller than -8. (including the 8)

This graph is the second one.

A successful basketball player has a height of 6 feet 88 inches, or 203203 cm. based on statistics from a data set, his height

Dafna11 [192]

The z-score is defined as the number of standard deviations above the mean. Its formula is z = (x - mean) / (standard deviation). So if we are given that this player's height has a z-score of 4.10 relative to others, this means that his height is 4.10 standard deviations above the mean.

ABC has vertices A(–3, –4), B(1, 5), and C(4,1). ABC is translated so that B’ is located at point (–3, 2). State the coordinates

koban [17]

If B went from (1, 5) to (-3, 2), that means it was shifted down 4 units and left 3 units. So for each of the other points, we subtract 4 from the x value, and subtract 3 from the y value. Point A is (-3, -4), moving this by subtracting 4 from x and 3 from y, we get A'(-7, -7). Point C was (4, 1), subtract 4 and 3, leaving C'(0, -2).
So A'(-3, -4), B'(-3, 2) and C'(0, -2)

SITUATION IN LIFE

When Determining the Relationship between my height and my weight.

BMI=WEIGHT/HEIGHT*HEIGHT.

BMI is the dependent variable

Weight and height are independent variables.

Step-by-step explanation: Mathematical representation of data or information is a very important strategy applied to solve certain Complex problems.

Mathematical representation helps to make Complex data or information easily understood,it helps one to derive the possible root cause and outcomes of problems,it also shows Relationship between various treatments or variables or drugs applied in solving problems example in treatment of Diseases.

BMI(BODY MASS INDEX) is a life situation where I have used Mathematical representation to solve, it used to show how your height and weight is related.

Independent variables are variables that do not cause any changes t other variables when altered.

Dependent variables are variables which can cause change in a situation when altered.

In this case BMI depends on The weight and height of a person, while the Weight and height of a person are independent on the BMI.
