Answer:
When you have two sets of data, one that represents an independent variable (X) and another that represents a dependent variable (Y) (it is a response of the first variable). A diagram called scatterplot can be generated to present the ordered pairs (X, Y) in the Cartesian plane to see how the two variables are related.
In this case the independent variable (X) is the age variable of the calf and the dependent variable (Y) is the weight of the calf.
The diagram can be seen in the attached file.

Answer:
19 lbs and 8 oz
Step-by-step explanation:
12 + 6 = 18   13 + 11 = 24     24 oz = 1 lb and 8 oz   1 lb and 8 oz + 18 = 19 lbs and 8 oz
 
        
             
        
        
        
Answer:
8/5
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
     = (4- -4)/(1 - -4)
    = (4+4)/(1+4)
    =8/5

Step-by-step explanation:
In a right triangle the altitude drawn to the hypotenuse is the geometric mean of the segments at which this altitude divides the hypotenuse.
So,

a. The area of the triangle ABC is

b. The legs of the right triangle are geometric means of the segment adjacent to this leg and the hypotenuse, so

 
        
             
        
        
        
Answer:
F^-1 (x) = 3x/2+5/4
Step-by-step explanation:
First, replace f(x) with y 
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y  
Replace y with f−1(x) f − 1 ( x ) 
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
