Q. Find the range and coefficient of range of the data :
100 , 200 , 400 , 600 , 900⇾ Solution :
largest value ( L ) = 900 & smallest value ( S ) = 100We know , Range is the difference between the largest and smallest value. By definition ,
1. Range = Largest value - Lowest value = 900 - 100 = [tex] \boxed{ \sf{800}}[/tex]
2. Coefficient of range =[tex] \large{ \tt{ \frac{L - S}{L + S} = \frac{900 - 100}{900 + 100 } = \boxed{ \tt{0.8}} }}[/tex]
Q. If f ( x ) = 9x - 8x and x belong to { 0 , 4 , 3 ,5 }. Find the range.
⇾ Solution:
When x = 0 , f ( 0 ) = 9 × 0 - 8 × 0 = 0
When x = 4 , f ( 4 ) = 9 × 4 - 8× 4 = 4
When x = 3 , f ( 3 ) = 9 × 3 - 8 × 3 = 3
When x = 5 , f ( 5 ) = 9 × 5 - 8 × 5 = 5
Range = { 0 , 4 , 3 , 5 )♨ Hope I helped! ♡

Answer:
Corresponding angles
Step-by-step explanation:
A corresponding angles is, and I quote, "the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal." (See image below)
So, looking at our words and graph, 5 and 1 are corresponding angles!

Josie wants to build a slide that is 15 feet long. If the angle of elevation for the side will be 30 degree, how high in feet will the top of the slide be ?
Answer: 7.5
Step-by-step explanation: draw a right triangle to represent the slide. the slide is 15 feet long, so the hypotenuse of the right triangle would be 15 feet. The angle from the bottom is 30 degrees according to the question. You want to find the angle opposite from the 30 degree angle so use sin(30). Sin=opposite/hypotenuse so sin(30)=x/15 sin(30) is 1/2 so 1/2=x/15. You multiply by 15 on both sides to get x by itself. 1/2*15=7.5

Jana, a high school principal, hosted a movie event at her school. Jana's assistant kept track of the number of students in each grade who attended the event. The distribution shown in the table
represents the number of students in each grade that were present.
Grade Level
Sophomore-56
Senior-70
Freshman-52
Junior-60
Jana knows that the grade levels are equally distributed across the school of 1,200 students. She would like to use a chi-square test to see if the proportion of individuals in each class at the
movie are also equally distributed. How many seniors would be expected at the event?
Answer:
59.5 Seniors expected
Step-by-step explanation:
"Equally distributed" means that it is expected that each grade has equal number of students for 1200 schools. This means 1200/4 = 300 students expected in each grade for 1200 students. The proportion would be 300/1200 = .25
The actual total of the school shown is (56+70+52+60) = 238
Therefore 238 * .25 = 59.5 expected students in each grade for this school
The proportion for each grade can also be found by just knowing that each grade has the same proportion.There are 4 grades so 1/4 = .25
Determine if the sequence below is arithmetic or geometric and determine the

Answer and Step-by-step explanation:
For the first graph:
The equation has a negative slope of [tex]\frac{1}{3}[/tex]. So, the equation is:
y = [tex]-\frac{1}{3} x[/tex]
For the second graph:
The graph is shifted down 4 units.
It has a positive slope of 3.
So the equation is:
y = 3x - 4

Solve the equation. x6−9=7 x = ___ (type only an integer - no words, variables, or equal signs)
Answer:
We want to solve the equation:
x*6 - 9 = 7
To solve this we need to isolate x in one side of the equation.
First, we need to add 9 in both sides of the equation to get:
(x*6 - 9) + 9 = 7 + 9
x*6 - 9 + 9 = 16
x*6 = 16
Now we can divide both sides by 6, to get:
x*6/6 = 16/6
x = 16/6 = 2.66
This is not an integer as the question wants, so i only can suppose that the question is incorrectly written.
If the equation was something like:
x/6 - 9 = 7
Using the same approach than before (the only difference is that we multiply both sides by 6 in the second step), we would get:
x/6 = 7 + 9 = 16
x/6 = 16
x = 16*6 = 96
x = 96
Which is an integer, so i suppose that the actual equation is "x/6 - 9 = 7" instead of "x*6 - 9 = 7"
