M is equal to the value m
Answer: A
Step-by-step explanation:
Only the first scatterplot has the first data point correctly plotted.
Answer:
Similarly, the distance between two points P1 = (x1,y1,z1) and P2 = (x2,y2,z2) in xyz-space is given by the following generalization of the distance formula, d(P1,P2) = (x2 x1)2 + (y2 y1)2 + (z2 z1)2. This can be proved by repeated application of the Pythagorean Theorem.
Step-by-step explanation:
Use a calculator
When you add the prices of the items you get a total of $17.74. If there is no tax you simply add 75 cents to 17.74 to get the amount paid therefore the answer is 18.49
Answer:
13
Step-by-step explanation:
The slope of the regression shows the average increase in response variable due to unit increase in explanatory variable. The regression equation of structure y=a+bx has slope=b.
The given regression equation y^=85+13x shows that the slope in the given equation is b=13. The response variable is amount of natural gas is used and explanatory variable is outside temperature in this case.
So, we can say that on increase of every unit of degree day the amount of gas used increase by 13 cubic feet.
