Solution :
a). The required linear regression model is
Price = 
b). The
for the variable "Age of part" is 0.0000
Since the
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
is not less than
, 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.
Answer: A^2
Step-by-step explanation:
Angle C + Angle B = Angle A
Set it up like a regular equation. I used:

As you can see, however, I inserted the "less than" symbol rather than the equal sign because values greater than a certain value can also equal "x". Solve it like a normal equation and you will arrive at:
<u>
</u>

This means that, as long as x is greater than 45, "6x" will be greater than "3x+135". Thus, if you bring 46 students, the Science Center will cost less.
If you know the whole price for 2.4 gallons, divide the whole price by 2.4 to get the cost for one, because when you multiply the cost for 1 by 2.4, you get the total.
7.56/2.4 = 3.15,
p= 3.15
1 bag=2cups. so, he uses 1 and 0.25 bags. there are 3.75 bags left. hope that helps)
