Answer:
The correct option is B.
Step-by-step explanation:
It is given that there is a strong, negative, linear relationship between x and y. where, x is the number of consecutive hours a worker has been assembling chainsaws and y is the number of chainsaws he can produce in an hour.
He finds that 70%of the variation in chainsaws produced per hour can be explained by the regression of y on x.


The slope is -0.7, therefore option B is correct.

Answer:
Step-by-step explanation:
47.91 + 23.96 + 35.09 = 106.96 <== actual answer
now if u were wanting an estimate, I would have done :
48 + 24 + 35 = 107
We are told to factor the expression ax + ay + bx + by. To factor the given expression, we must use grouping. The first step is to grouping is to 'group' the expression into two different binomials. This results in (ax + ay) + (bx + by). From the first binomial, we can factor out a. From the second, we can factor out b. After doing this, we get a(x + y) + b(x + y). We immediately notice that there are two like terms, (x + y). We can group the two remaining terms together to get (a + b). When we put the two terms together, we get (a + b)(x + y). Therefore, the factored version of ax + ay + bx + by is (a + b)(x + y). Hope this helped!
With pi, repeating decimals, etc. Hope this helped!
