You are given a set of data regarding the truck with the <span>distance y, in miles, traveled by a truck in x hours:
Time (x) (hours) 1 2 3 4
Distance (y) (miles) 50 100 150 200
I used excel to plot this data and get an equation and the value of r to anwer the following questions.
Part A: The most likely value of the correlation coefficient of the data in the graph is 1, meaning that the distance travelled by the truck and the time it takes to travel is directly related or directly proportional.
Part B: From the graph, i got an equation y = 50x with a slope of 50.
Part C: The table presented above is a correlation because both variables are directly related and forms a straight line rising to the right.</span>

Answer:
20
Step-by-step explanation:
If you take (2x+5) (2x+5) = 0
then 4x^2 + 20x +25 = 0
Answer:
cubic units.
Step-by-step explanation:
Let m represent length of the rectangular prism.
We have been given that the width of a rectangular prism is six times its length, so width of the prism would be 
.
We are also told that the height is five times its length, so height of the prism would be 
.
We know that volume of rectangular prism is height times width times length.
Therefore, the volume of the given rectangular prism would be cubic units.
