Step-by-step explanation:

PART A

it wpuld be a correlation

PART B Write a function which best fits the data.

So, f(x)=5x+2

PART C

slope and y-intercept of the plot indicates that its going up 5 positive points

The change in Y over the change in X.

The number of units of outputs per number of workers.

Took me a minute to think.

Form ratios.

x, the small triangle, forms a ratio with 6, the big triangle.

The part of the side that is equal(with the dash) that is part of the small triangle is equal to 6-x, the big triangle.

Yes, you can cross-multiply here!

\frac{6}{x}  =  \frac{8}{6-x}

<em>Now,</em><em> </em>cross multiply.
P.S. Use distributive property.

36-6x = 8x

Add 6x on both sides.

36=14x

Divide by 14 on both sides.

x = \frac{36}{14} = \frac{18}{7}

A triangular lot bounded by three streets has a length of 300 feet on one street, 250 feet on the second, and 420 feet on the th

Apply the Law of Sines.

sin A      sin B     sin C
-------  = -------- = --------
    a            b           c

Inserting the given data, 

 sin 36      sin B     sin C
---------  = -------- = --------
  250          300        420
                                                                   300 sin 36
Then 300 sin 36 = 250 sin B, and sin B = ---------------- = 0.705 
                                                                        250

Thus, arcsin B = 0.783 rad = 44.857 degrees, or about 45 degrees.

Taking B to be 45 degrees and the given angle 36 deg, then the 3rd angle must be 180 - (45+36) = 99 degrees (which is opposite the 420-ft side).

At this point we apply Heron's formula.  You should look this up on the 'Net.

                                      a + b + c        250 + 300 + 420
First, we calculate S = --------------- = ------------------------ = 970/2 = 485
                                            2                       2

and then calculate sqrt (S(S-A)(S-B)(S-C):

Area of triangle / lot is then:

A = sqrt(485(485-250)(485-300)(485-420))
    = sqrt(485(235)(185)(65) )
    = 37021 square feet
