Answer:
tan∠Y = 2,14
Step-by-step explanation:
First , we need to determine XY
in order to do that we use the Pythagorean theorem :
XY = √(85^2-77^2) = 36
tan∠Y = 77/36 = 77÷36 = 2,138888888889
Answer:
The expression of the given statement is 8 y - 2 = 6.
Step-by-step explanation:
Here, let the unknown number = y
Now, product of y and 8 = 8 times y = 8 y
Also, two less than the product = Product - 2
So, two less than the product of 8 and y = 8 y - 2
Now, this above expression is equivalent to 6.
⇒8 y - 2 = 6
Hence the expression of the given statement is 8 y - 2 = 6.
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.
