Answer:

a. The estimated coefficient for size is approximately s  =13.8096595404

b The number of  predictors are 2

Step-by-step explanation:

From the table we can see that

   The standard error of size is  e =  1.2072436

  and the test statistics of size is T_s =  11.439

The estimated coefficient for size is evaluated as

        s=e * T_s

=>    s =1.2072436\cdot 11.439

=>        s  =13.8096595404

The number of predictors are two and this include size and FP

55 degrees. If you add the other three angles together you get 305. Considering that a circle is 360 degrees, you would subtract those two and get 55.

(x + 4)(3x + 2) = ____________ 2. (3x – 1)(2x – 5) = ____________ 3. (5x + 2)(2x + 5) = ____________ 4. (4x – 1)(2x + 7) = _____
Sidana [21]

Answer:

Step-by-step explanation:

Use FOIL method

1) (x +4 )(3x +2) = x*3x + x*2 + 4*3x + 4*2

                        = 3x² + 2x + 12x + 8

                        = 3x² + 14x + 8

4) (4x - 1) (2x + 7) = 4x*2x + 4x*7 + (-1)*2x + (-1) * 7

                           = 8x² + 28x - 2x - 7

                            = 8x² + 26x - 7
