∠1 and ∠2 will have the values 33° and 147° respectively when they form a Linear Pair.
In the question, It is given that ∠1 and ∠2 form a Linear Pair.
So, ∠1 and ∠2 = 180°, Also it is stated that ∠1 is 18° lesser than 5 times ∠2.
Taking ∠2 = x we get ∠1 = 5x-18
Now for Linear Pair, we have ∠1 + ∠2 = 180°
putting values of ∠1 and ∠2 we get : (5x-18) + x = 180
Solving the equation => (5x-18) + x = 180 => 6x = 198
=> x = 33
Putting the value of x in both ∠1 and ∠2 we get :
∠2 = 33° and ∠1 = 5(33) - 18 => ∠1 = 147°
Hence, we get ∠1 and ∠2 measures 147° and 33° respectively.

The likelihood that exactly 13 students will pursue arts in the coming year is 76.47%.
What do we mean by probability?Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how probable they are. Statistics is the study of events governed by probability.So, to find the probability:
Given:
Each year, there are 17 students who study art.We now want to calculate the likelihood that 13 students will pursue arts in the following year.
That is,
P(13 will take art the next year) = 13/17 × 100%P(13 will take art the next year) = 76.47%Therefore, the likelihood that exactly 13 students will pursue arts in the coming year is 76.47%.

The profit as a function Q is Q² + 90Q + 5000.
How to calculate the profit?It should be noted total revenue = Price × Quantity = 100Q
Total cost = 5000 + 10Q + Q²
Therefore, profit will be:
= Revenue - Cost
= 100Q - (5000 + 10Q + Q²)

You want an average of at least 30 active minutes each day during the week. How many active minutes do you need on Sunday to achieve your goal? Make an argument for your answer using a bar graph.
Using the mean concept, it is found that you need at least 40 active minutes on Sunday to achieve your goal.
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
In a week, there will be 7 observations, and a bar graph can represent each observation(time in minutes). They are given as follows:
15, 45, 20, 0, 60, 30 and x.
We want the mean to be of 30, hence:
30 = (15 + 45 + 20 + 0 + 60 + 30 + x)/7
170 + x = 210
x = 210 - 170
x = 40.

Answer:
x = 35
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
x + 52 + x + 2x - 12 = 180
4x + 40 = 180 ( subtract 40 from both sides )
4x = 140 ( divide both sides by 4 )
x = 35
find an equation for the plane consisting of all points that are equidistant from the points (−7, 1, 1) and (3, 3, 5).
The equation for the plane consisting of all points that are equidistant from the points (−7, 1, 1) and (3, 3, 5) is 20x + 4y + 8z = -9.
How to determine the equation for this plane?In order to determine the distance of this plane (x, y, z) with the given points, we would use the distance formula.
Mathematically, the distance between three (2) points that are on a coordinate plane can be calculated by using this formula:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]
For these points (x, y, z) and (−7, 1, 1), the distance is given by:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]
Distance = √[(x₂ - (-7))² + (y₂ - 1)² + (z₂ - 1)²]
Distance = √[(x₂ + 7)² + (y₂ - 1)² + (z₂ - 1)²]
By using the algebraic formulas, the expanded expression is given by:
(a - b)² = a² - b² - 2ab
(a + b)² = a² + b² + 2ab
Distance = √[(x² + 14x + 49) + (y² - 2y + 1) + (z² - 2z + 1)] .......equation 1.
For these points (x, y, z) and (3, 3, 5), the distance is given by:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]
Distance = √[(x - 3)² + (y - 3)² + (z - 5)²]
Distance = √[(x² - 6x + 9) + (y² - 6y + 9) + (z² - 10z + 25)] .....equation2.
Since both distances are equidistant, we would equate eqn. 1 and eqn. 2 and then simplify:
√[(x² + 14x + 49) + (y² - 2y + 1) + (z² - 2z + 1)] = √[(x² - 6x + 9) + (y² - 6y + 9) + (z² - 10z + 25)]
(x² + 14x + 49) + (y² - 2y + 1) + (z² - 2z + 1) = (x² - 6x + 9) + (y² - 6y + 9) + (z² - 10z + 25)
x² + 14x + 49 + y² - 2y + 1 + z² - 2z + 1 = x² - 6x + 9 + y² - 6y + 9 + z² - 10z + 25
14x + 6x - 2y + 6y - 2z + 10z + 52 - 43 = 0
20x + 4y + 8z + 9 = 0

Determine the image of A(1,-3) after the following composition of transformations:
Rotation 90 degrees about the origin
Translation: f(x,y)=(x+2,y)f(x,y)=(x+2,y)
The image of the point A after the given compositions of transformation will be (5, 1).

The total weight of the two animals is 1.3 x 10^4 lbs.
How to determine the total weight of the two animals?The given parameters are
Animal 1 = 4.23 x 103 lbs.
Animal 2 = 8.7 x 103 lbs.
Rewrite the parameters properly
Animal 1 = 4.23 x 10^3 lbs.
Animal 2 = 8.7 x 10^3 lbs.
The total weight of the two animals is calculated as
Total weight = Animal 1 + Animal 2
This gives
Total weight = 4.23 x 10^3 lbs + 8.7 x 10^3 lbs.
Factor out 10^3 lbs
Total weight = (4.23 + 8.7) x 10^3 lbs.
Evaluate the sum
Total weight = 12.93 x 10^3 lbs.
Rewrite as
Total weight = 1.293 x 10^4 lbs.
