Answer:
The slope of this line is 1021.
Step-by-step explanation:
A regression line has the following format:
y = b + ax
In which a is the slope, that is, how much y changes with a variation of a single unit in x.
In this problem, our line is:
forest loss=7500+1021x
In which x is the number of years after 2000.
So the slope of this line is 1021.
Find the mean of thw data 11,11,12,13,13,13,14,14,15,15,16,16,18
amid [387]
Answer:
the mean is 13
Step-by-step explanation:
The way to find the mean of a set of numbers is to add all the numbers together and divide the sum by the number of numbers. so 11 + 11 + 12 + 13+ 13 + 13 + 14 + 14 + 15 + 15 + 16 + 16 + 18 / 13 = 13.9
Answer:
7
Step-by-step explanation:
[(1/3 – 1/9)² + (1/3)³] : (1/3)⁴
Next, we shall simplify (1/3 – 1/9)². This is illustrated below:
(1/3 – 1/9)² = ((3 – 1)/9)² = (2/9)²
[(1/3 – 1/9)² + (1/3)³] : (1/3)⁴
= [(2/9)² + (1/3)³] : (1/3)⁴
= [4/81 + 1/27] : 1/81
= [(4 + 3)/81 ] : 1/81
= 7/81 : 1/81
= 7/81 ÷ 1/81
Invert
= 7/81 × 81/1
= 7
