Answer:
Choice B
Step-by-step explanation:
We can perform a least squares regression model in Ms. Excel to determine the equation of the line of best fit for the data given;
The first step is to enter the data into any two adjacent columns of an excel workbook. Next, click on the Data ribbon followed by the Data Analysis tool pack. We then proceed to select regression from the pop-up window. The final step is to select the y range and the x range of values from our data.
Once we click ok, Excel returns our least squares regression model as shown in the attachment below.
The coefficient of X variable 1 is our slope.
The veterinary should give the dog 0.1 m if medicine
Fourth test mark should be 86
85 + 82 + 75 + 86 = 328
328 divide by 4 (as there are four tests) = 82
In order to find what 10% of a day is:
A day is 24 hours long.
Divide 24 by 100, then multiply the answer by 10.
24/100=0.24
0.24*10=2.4
So, 10% of the day is 2.4 hours.
2 hours and 30 minutes can be written as a decimal as 2.5.
So, 2 hours and 30 minutes is slightly more than 10% of the day.
