Step-by-step explanation
larger angle = 76+2x
smaller angle = x
supplementary angles add up to 180
∴(76+2x)+x=180
76+3x=180
3x= 180-76
3x = 104
x = 104/3
x = 34.7°(smaller angle)≈ 35
larger angle = 76+2(34.7)
=76+69.4
=145.4≈ 145
Given the data points, (x, y) of a linear function: (2, 11), (4, 10), (6, 9), (12, 6), what is the function? What is the slope?
NeX [460]
Answer:
The function is .
The slope is .
The y-intercept is .
Step-by-step explanation:
Our aim is to calculate the values <em>m</em> (slope) and <em>b</em> (y-intercept) in the equation of a line :
We have the following data:
To find the line of best fit for the points given, you must:
Step 1: Find and as it was done in the table below.
Step 2: Find the sum of every column:
Step 3: Use the following equations to find <em>b</em> and <em>m</em>:
Step 4: Assemble the equation of a line
The graph of the regression line is:
The tree is 19.55 meters tall.
Step-by-step explanation:
Shadow of tree = 20.7 meters
Height of tree = x
Hiker's shadow = 1.8 meters
Hiker's height = 1.7 meters
Using proportion
Shadow of tree : Height of tree :: Shadow of hiker : Height of hiker
Product of mean = Product of extreme
Dividing both sides by 1.8
The tree is 19.55 meters tall.

Adding!
= 80,00 + 7,000
= 87,000 + 400
= 87,400 + 60
= 87,460 + 3
=87,463
