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:
5(x+1) -2(y-3) = 0
Step-by-step explanation:
For a given line ax+by=c and point (h, k), a perpendicular line through the point can be written as ...
b(x-h) -a(y-k) = 0
A graphing calculator shows the point of intersection of the graphs of the two lines to be (x, y) = (-1, 3), so the line perpendicular to 2x+5y=5 through that point can be written ...
5(x+1) -2(y-3) = 0
_____
In the attached graph, the requested line is shown in black.
First put these in order from least to greatest.
1,2,2,4,8,9,9 is the correct order
Range is when we subtract the greatest value of our data set from the smallest so in our case it would be 9-1 which leaves us with our answer that 8 is your range.
The total number of calories for 18 cups of milk is 1620 calories.
If two cups of milk is 180 calories then divide 180/2 to find the unit rate.
Then multiply 90 by the number of cups (18) and then you get the total number of calories for that many drinks.
1 pound = 16 ounces so let's go ahead and convert 11 pounds to ounces by multiplying by 16. 11×16=176 and then add 13 to that 176+13=189
so 12 pounds and 13 ounces= 189 ounces
