Answer:
1) B. on, 2) D. 19.2, 3) C. 0
Step-by-step explanation:
1) The value of y according to the regression line is:
Hence, the point (8,19.2) is <em>on </em>the least-squares regression line.
2) The value of y according to the regression line is 19.2.
3) The residual is the difference between the value from the regression line and the real value. In this case, the residual value is 0.
Answer:
36
Step-by-step explanation:
First we need to write out some of the common multiples of 4 and 6.
12, 24, 36
The number 36 is between 25 and 45 so it is our answer
If you want to multiply a decimal by a whole number,just ignore the decimal point and multiply by normal.
X should equal 12.5
You have to split the isosceles acute triangle in the middle of the polygon down the middle, and find what the now right isosceles tringle is. Since we already know that there's a 50 degress and a 90 degress there all you have to do is add those two numbers together and subtract from 180. Thena after you've done that you just need to multiply 40 by 2 and bata bing, bata boom you have 80 degress as your top, you already have a 50 and the last one has to be 50. Divide 50 by 4 and you get 12.5
50+90=140
180-140=40
40 * 2 = 80
80 + 50 + x = 180
x= 50
4*x= 50
x=12.5
