Measuring the height of a tree is usually more difficult than measuring the diameter of the tree. Therefore, many researchers use regression models to predict the height of a tree from its diameter measured at 4 feet 6 inches from the ground. The following computer output shows the results of a linear regression based on the heights, in feet, and the diameters, in inches, recorded from 31 felled trees.

Answer:
95°, 110°
Step-by-step explanation:
Since we're dealing with a cyclic quadrilateral ,
m<T + m<R 180°
7y + 11y = 180°
18y = 180°
y = 10°
Also,
m<S + m<U = 180°
3x+5+3x-5= 180°
6x = 180°
x = 30°
m<S = 3x+5 = 3(30)+5
= 95°
m<R = 11y = 11(10)
= 110°
Given -
m∠R = (11y)°m∠S = (3x + 5)°m∠T = (7y)°m∠U = (3x - 5)°To find -
m∠Rm∠S(nullifying x and y)
Explanation -
As we know this is a cyclic quadrilateral and it's either pair of the opposite angles sum up to 180°.
Therefore,
m∠S + m∠U = 180° ---(1)
m∠R + m∠T = 180° ---(2)
Solution -
Substituting the values of the measure of angles in (1)
➜ m∠S + m∠U = 180°
➜ (3x + 5)° + (3x - 5)° = 180°
➜ 6x = 180°
➜ x = 180/6
➜ x = 30
Therefore, m∠S = (3x + 5)° = {3(30)+5}° = (90+5)°
m∠S = 95°
Substituting the values of the measure of angles in (2)
➜ m∠R + m∠T = 180°
➜ (11y)° + (7y)° = 180°
➜ 18y = 180°
➜ y = 180/18
➜ y = 10
Therefore, m∠R = (11y)° = (11×10)° = 110°

Answer:
18 tala
Step-by-step explanation:
The exchange is proportional, so the number of tala Ming receives will be proportional to the number of dollars she exchanges.
x / ($6) = 6 tala / ($2)

6.4r−7−2.9r simplified is
Answer:
3.7r -7
Step-by-step explanation:
Basically you would subtract 6.4 and 2.9 because there is a negative sign and they have the same variable. Then you would put it (2.9r)first since it is in order and you can't combine 7 and 2.9r so you leave it like that.

Step-by-step explanation:
Apparently function f is defined by the ordered pairs (8, 6), (10, 9), (12, 3).
The inverse function will be defined by the ordered pairs with the input and output reversed:

I need help with 15.) 17.) and 19.) I have attached the answers I just need help with how to solve them
Answer:
Step-by-step explanation:
They are all solved kind of the same way. If the vertex of the angle is outside of the circle, subtract the intercepted arcs and divide by 2
for 15) one arc is marked but you can figure out the other arc because there are 360 degrees in a circle 360 - 102 = 258. So the two arcs are 102 degrees and 258 degrees.
some of the problems you can set up the equation and solve.
17) 63 = {(360-x) - x} /2 multiply by 2
126 = {(360-x) - x} combine like terms
126 = 360 - 2x subtract 360
-234 = -2x divide by -2
117 = x
? = 117 degrees

The Pyramid of Menkaure is a square pyramid located in Giza. The pyramid has a height of about 215 feet, a slant height of about 274 feet, and a base side length of about 339 feet. After a windstorm, an architect was tasked with inspecting the outer surfaces of the pyramid for damage. How many square feet does the architect need to inspect? Type the correct answer in the box. Use numerals instead of words. The architect will need to inspect square feet
Answer:
The architect will need to inspect 185,772 square feet.
Step-by-step explanation:
The square feet the architect must inspect represents the lateral surface area of the square pyramid. Since the base of the pyramid is a regular polygon, a square, then the given formula can be used. Let P be the perimeter of the base and l be the slant height of 274 feet.
Find the perimeter of the base by multiplying the length of a side, 339 feet, by the number of sides of the base, 4.
So, the architect will need to inspect 185,772 square feet of the pyram
The total of 109327.5 feet² of the square area the architect needs to inspect.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right angle triangle, equilateral triangle, and much more.
A pyramid consists of 3 equal triangles given that the vertical height of a triangle is 215 feet, and the base is 339 feet.
Area of one triangle = (1/2) × base × height.
⇒ (1/2) × 339 × 215
⇒ 36442.5
Since in a pyramid, there are a total 3 triangles so
Total surface area = 3 × surface area of 1 triangle.
Total surface area = 3 × 36442.5 = 109327.5 hence correct answer will be 36442.5.

y = -2/3 x + 15
y = −15x + 3/2
y = -3/2 x + 15
Answer:
4th option
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 12) and (x₂, y₂ ) = (6, 6) ← 2 points on the line
