Answer:

5 days

Step-by-step explanation:

Speed = 359 miles/day

Distance = 1,462 mile

Use this formula to calculate time ( in number of days);

Time = Distance / speed

Next, plug in the numbers given into the formula to calculate time;

Time = 1462 / 359 = 4.0724

Since you are told to round off in days, you will round up 4.0724  to 5 days.

Therefore, it will take Tom 5 days to drive 1,462 miles.

If the r-value, or correlation coefficient, of a data set is 0.854, what is the
Kruka [31]
Answer with explanation:
Coefficient of determination(r²), is defined as, how well the data values are associated with each other when Regression line is drawn. In regression analysis, the coefficient of determination measures , how well the regression predictions approximate the real data points, means it measures the closeness between two variables.The Value of r², lies between 0 to 1. If value of r²=1, it shows ,regression line that is data values are Perfectly associated with each other.
If ,r²=0, it means there is no variation between two variables.There is 0% variation between two variables.
→Coefficient of Variation=[Correlation coefficient]²
=r²
=(0.854)²
=0.854 × 0.854
=0.729316
=0.730(Approx)
