In order to meet safety guidelines, a roof
contractor determines
that she must place the
base of her ladder 6 feet
away from the house.
making an angle of 76
with the ground. To the
nearest tenth of a foot.
how far above the
ground is the eave of the
roof?

b. x- 48 =120

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
