Answer:
a. is not found to be significant.
Step-by-step explanation:
Regression analysis is a statistical technique which is used for forecasting. It determines the relationship between two variables. It determines the relationship of two or more dependent and independent variables. It is widely used in stats to find trend in the data. It helps to predict the values of dependent and independent variables. In the given question, there are 25 observations and the regression equation is given. X and Y are considered as dependent variables.
8 is te answer > i hope that helpped
Answer:
(2, 1).
Step-by-step explanation:
f(x)=2x^2-8x+9
Find -b/2a first, it's -(-8)/2(2)=8/4=2.
Then find the y-coordinate of the vertex.
2(2)^2-8(2)+9=2(4)-16+9=8-16+9=-8+9=1
Had trouble reading your post. It's important that you separate each equation with plenty of spaces, or, b etter yet, type only one equation per line:
<span>x-y=19 -2x+y/6=28 should be:
</span><span> x-y=19
-2x+y/6=28
Does (-31,-56) satisfy this system? Is (-31) - (-52) = 19? No. Move on to the next system and check again whether or not (-31, -56) is a solution.</span>
