Answer:
m = 3
Step-by-step explanation:
Find the slope of the line connecting (-2,-3) and (-4,-9). (Note: you must use those parentheses.)
As we go from x= -4 to x = -2, an increase of 2, y increases by 6 from -9 to -3. The slope of this line is m = rise / run = 6/2 = 3.
Answer:
Triangle Sum Theorem
Step-by-step explanation:
I believe it is that since we are given two angles, D is 47 and A is 90. Using the Triangle Sum Theorem, we know that a triangle's angles equals to 180 degrees so, 90+47=137, then 180-137=43.
Hope this helps!!! PLZ MARK BRAINLIEST!!!
Answer:
The regression line is not a good model because there is a pattern in the residual plot.
Step-by-step explanation:
Given is a residual plot for a data set
The residual plot shows scatter plot of x and y
The plotting of points show that there is not likely to be a linear trend of relation between the two variables. It is more likely to be parabolic or exponential.
Hence the regression line cannot be a good model as they do not approach 0.
Also there is not a pattern of linear trend.
D) The regression line is not a good model because there is a pattern in the residual plot.
You would use the A=Pe^rt equation here. A (total amount)= P (initial amount) e^r(rate)x t(time). Here is the equation for you to plug into your calculator. A=350e^0.45x10. The answer is..31505.99596
