Answer:
False
Step-by-step explanation:
Given that two linear regression models have the same number of explanatory variables
First model has coefficient of determination as 0.45 while other
0.65
we know that R^2 is the proportion showing the variation of dependent because of variation in independent variables.
Hence a higher R square is always better because it ensures more linearity and hence more accuracy in the regression equation.
Hence 0.65 model is better than 0.45 model.
The given statement is false.
Answer:
Function
Step-by-step explanation:
This is a function.
The rule of a function is that every input has one output.
What that means is that for every x value, there is only one y value.
You can test this with the vertical lines method. If you draw vertical lines through the function, each vertical line should only intersect with the graph at a single point. If it intersects at two, it is not a function.
96 necklaces
You divide the amount of beads total by the amount of beads on each necklace.
( 8160 divided by 85 and 2880 by 30)
Answer:
224
Step-by-step explanation:
the area of a circle is 
, so for the circle plug in your numbers:
(3.14)(
) = 615.44
divide this by 4 because t=in the picture you only have a fourth of a circle:
615.44 / 4 = 153.86
the formula for area of a trapezoid is 
× h
so plug in your values: 
× 5
you get 70
add 70 and 153.22
70 + 153.22 = 223.22
this can round to 224
