You have 7 tiles of each t by t+3.

One tile has an area of

t * (t+3) = t^2 + 3t

So in total the area is

7* (t^2 + 3t)

Find 3 consecutive odd integers such that 10 times the first is 59 more than the third?
Nikolay [14]

Answer: The required three consecutive odd integers are 7, 9 , 11.

Step-by-step explanation:

Let x , x+2 , x+4 be the three consecutive odd integers.

As per given ,  

10(x) = 59+x+4

⇒10x= 59+x+4

⇒ 9x= 63

⇒ x= 7   [ divide both sides by 7]

Hence, the required three consecutive odd integers are 7, 9 , 11.

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.
