The method of least squares is a widely used method of fitting curve for a given data
Step-by-step explanation:
It is the most popular method used to determine the position of the trend line of a given time series. The trend line is technically called the best fit. ... The sum of the deviations of y from their corresponding trend values is zero.
Answer:
b Superscript positive
Step-by-step explanation:
Negative exponents in the denominators can be evaluated by moving the function from the denominator to the numerator and changing the power from negative to the positive.
We have
1/b⁻² = b²
Moving the function with a power from denominator to numerator or from numerator to denominator changes the sign of the power. It is not equal to zero.
This is the property of exponents.
Answer:
4.5 times
Step-by-step explanation:
Packing to Buying is 2:9
Therefore, Buying to Packing will be 9:2.
9/2 = 4.5
Answer:
The slope of the equation is -3.
Step-by-step explanation:
Given : Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each minute.
To find : What is the slope ?
Solution :
Let x be the number of minutes taken to dig the ground.
He started digging his way deeper into the ground, descending 3 meters each minute i.e. '-3x'
Let y is the total distance travel to dig the ground.
Mr. Mole's burrow lies 5 meters below the ground.
The equation form is 
Comparing with general slope form i.e. 
where m is the slope.
The slope of the equation is -3.
