Answer:
x=10
Step-by-step explanation:
The two line segments should be equal, so you can set 2x-10 equal to x.
2x-10=x
-10=-x
x=10
Answer:
1. what is a residual?
A. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.
2. The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.

A. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.
2. In what sense is the regression line the straight line that "best" fits the points in a scatterplot?
The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.
Answer:
1/10
Step-by-step explanation:
we multiply by the reciprocal when we work with fractions and division.
Now you just multiply across.
Therefore, you have 2/20, which simplifies to 1/10.
Answer:
:))
Step-by-step explanation:
Collect like terms, keeping the integer rules in mind
5. 5a + 9b - 3a + 2b + 4a
5a + 4a - 3a + 9b + 2b (REARRANGE, if you find it to help)
6a + 11b
6. 7m + 3n - 8m + 2n + 10m
7m + 10m - 8m + 3n + 2n
9m + 5n
10. 10m²n + 5mn + 9m²n - 2mn
10m²n + 9m²n + 5mn - 2mn
19m²n + 3mn
Try to do the rest on your own :)
Answer:
3/8 and 3/5
Step-by-step explanation:
Given that a family has three children. Using b to stand for a boy and g for girl give the following we can write sample space for a family having three children as
(bbb, bbg, bgg, bgb, gbb, gbg, ggb, ggg)
E - exactly two boys
Sample space count = 8
Exactly two boys count = 3
a) p(E) = 
b) odds for E is probability/1-probability
=
