Four out of every five teenagers surveyed went to a movie theater in the past month. If 95 teenagers were surveyed, how many had gone to the movies in the past month?
Answers
Answer:
76 teenagers went to movies in the past month.
Step-by-step explanation:
The number of teens who went to movie out of every 5 teens = 4
Total teens surveyed = 95
Let, out of 95 teenagers , the teens who went to movie = m
So, the ratio of people who went : who were surveyed = 4: 5
Now, BY THE LAW OF RATIO AND PROPORTIONALITY
or,
So, m = 76
⇒ 76 teenagers went to movies in the past month.

3. Name two pairs of vertical angles.
Answers
Two angles, namely ∠AOE and ∠COD, are supplementary to angle ∠DOE.
A pair of complementary angles consists of angles ∠BOC and ∠COD.
Two pairs of vertical angles are ∠AOE and ∠COD.
What are supplementary angles
When two angles are supplementary, it means that the sum of their measures is 180 degrees.
In this case, the angles ∠AOE and ∠COD are stated to be supplementary to angle ∠DOE. This implies that if you were to add the measures of ∠AOE and ∠COD together, their sum would be 180 degrees, which is the definition of supplementary angles.
Complementary angles are angles whose measures add up to 90 degrees. In the statement, the angles ∠BOC and ∠COD are identified as forming a pair of complementary angles.
Vertical angles are a pair of non-adjacent angles formed by intersecting lines. In the statement, the pairs of vertical angles are given as ∠AOE and ∠COD.

The TREATMENT sum of squares measures the variability of the sample treatment means around the overall mean.
The sum of squares is used to measure the variation about the mean, In ANOVA we have:
• Sum of square Error : measures the variation between each observation in a group and the mean of that group.
• Sum of square treatment : measures the variation between the mean of each group and the overall mean.
• Total Sum of Square : measures the variation between each observation and the overall sample mean.
Hence, Treatment sum of squares measures variation between sample treatment and overall sample mean.

Part A: What is the solution to the pair of equations represented by p(x) and f(x)? (3 points)
Part B: Write any two solutions for f(x). (3 points)
Part C: What is the solution to the equation p(x) = g(x)? Justify your answer. (4 points)
Answers
A solution to a pair of equations on a graph is represented when the lines cross each other. Look for the point where p(x) and f(x) cross each other.
p(x) and f(x) cross at (6,2), which is the solution to both equations.
B.
A solution for a singular line is represented by any point that falls on the line. A line will have infinite solutions for infinite x-values.
Two solutions that we can write for f(x) are the points (0, -4) and (4, 0), as the line crosses both points.
C.
This question is exactly the same as part A: a solution to both lines is represented by where they cross.
p(x) and g(x) cross at (3, 6), which is the solution to both equations.
