Answer:

(2^4) + ((-8 * 2)/4) = 12

Step-by-step explanation:

2^4 - 8 * 2 / 4 = 12

First, turn the equation into this

(2^4) + ((-8 * 2)/4) = 12

Always do exponents, multiplication and division first

So, 2^4 is 16. Next do -8 * 2 which gets you -16, then divide that by 4 to get -4. Lastly, add on the 16 to the -4 to result in 12.

LenKa [72]

Solution :

a). The required linear regression model is

Price = $-1242.986 + 75.017 \times \text{age of part} + 13.973 \times \text{ number of bidders}$

b). The $\text{p-value}$ for the variable "Age of part" is 0.0000

Since the $\text{p-value}$ is less than 0.05, so it is significant to the model.

The p-value for the variable "Number of bidders" is 0.1940

Since $\text{p-value}$  is not less than $0.05$, so it is significant to the model.

c). We cannot say that model is significant because variable " the number of bidders" is not significant.

But as both variables have positive coefficient so as the variable increases the price received for the item also increased.
