I’m not quite sure about domain but range is the difference between the two numbers; on a line graph the range would be the first number and the last if it is not continuous.

How would I write the line of equation for (0.5,4.5) and (8,0.5)
Pepsi [2]

Answer:

Step-by-step explanation:y – y1 = m(x – x1)     * substitute (-0.5, 4.1) for x1 and y1

y - (4.1) = (0.8)(x - (-0.5))    

y - 4.1 = 0.8(x + 0.5)     * distribute the 0.8

y - 4.1 = 0.8x + 0.4     * add 4.1 to both sides

y = 0.8x + 4.5

this is the example hope this helped!

(15 POINTS) A student is chosen at random from a school. Why are the events "choosing a student of age group 5−10" and "choosing
Sati [7]
In probability, you study the chances, odds or likelihood of the event occurring. This is determined by dividing the number of possibilities to the total number of events. But terms may come up such as 'mutually exclusive'. Suppose, event A is for students ages 5-10, while event B is for students ages 11-15. The events A and B are said to be mutually exclusive when they do not intersect or meet at some point. In other words, when a student is in group A, he cannot be in group B because that becomes invalid and untrue. That seems logical because a student cannot be both 6 years old and 12 years old, right?

Hence, the answer to this question is letter C.

You are planning to put a new digital flat t.v on a wall that is 12ft long and 9ft high. the digital t.v has a diagonal of 72 in
Pie
Area of wall = 9 * 12 = 108 ft^2
Width of TV = x
Lenght = 2x
Diagonal of TV = 72 " = 6 ft


x^2+(2x)^2=6^2
x^2+4x^2=36
5x^2=35
x^2=36/5
x=sqrt(36/5)
Width = 2.68 ft.
Length = 2.68 * 5.36 = 14.36 ft^2
Area of wall - area of tv = 108 - 14.36 = 93.64 ft
