Answer:
Step-by-step explanation:
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:
x=24/7
Step-by-step explanation:
3(x+2)+4(x-5)=10
3x+6+4(x-5)=10
3x+6+4x-20=10
7x+6-20=10
7x-14=20
7x=24
x=24/7
