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.

This one was difficult one but is made to equations like such.
x+7=2y
x+y-9=13
using substitution i came to
x(the first number)=12.333
y(the second number)=9.667
hope i helped
7/8 dice 7.19 is a fraction you convert it to standard form which is a fraction
Answer: a) The size of angle x is
.
b) A. Corresponding angles.
Step-by-step explanation:
Since AD is parallel to EH and CG is a transversal intersecting them at B and F, then
...(i)
[Pair of corresponding angles are equal lie on the same side of the transversal]
Here,
, 
then,
[Substitute values in (i)]
Hence, the size of angle x is
.
Reason for this: Corresponding angles.
