Answer: D. ( -2 , 3 )
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x.
Answer:
Step-by-step explanation:
Parts + 3($40 labor)=183.30
parts + 120=183.30
parts=63.30 but it includes tax. To find costs of parts before tax you
63.30/1.055=60 so parts are $60
or to solve with one equation:
parts(1.055) + 3($40 labor) = 183.30
parts(1.055) + 120=183.30
parts(1.055)=63.30
Parts = 63.30/1.055
parts = 60
By inserting (1/10)x all previous x values are larger apart, x is your "speed" progressing through the function so by multiplying it with 1/10 you are "slower" and it stretched the function by a factor of 10 along x
also y=10g(stuff)
so all y coordinates are multiplied by a factor of 10 stretching the function along y
so in both the x and y direction the function is stretched by a factor of 10
Answer:
It is not reasonable to use the line of best fit to make predictions from the data.
Explanation:
A correlation coefficient of r = 0.15 means that the goodness of fit for the data from linear regression analysis is
r² = 0.15² = 0.0225.
When r²=1, it means that correlation between the dependent and independent variable is perfect, and the dependent variable can be predicted reliably.
When r²=0, it means that there is absolutely no correlation between the dependent and independent variable.
When r²>0.9, it means that reasonable correlation exists between the dependent and independent variable.
A value of r²=0.0225 is extremely low, therefore it is not reasonable to use the line of best fit to make predictions.
