1. What is a residual?

sladkih [1.3K]

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.

Step-by-step explanation:

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. 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.

the vertices of triangle PQR are P(-3, 8), Q(-6, -4), and R(1, 1). If you reflect triangle PQR across the x-axis, what will be t

otez555 [7]

Answer:

The coordinates of the vertices of the image will be:

P'=(-3,-8)

Q'=(-6,4)

R'=(1,-1)

Step-by-step explanation:

If you reflect a point P=(x,y) across the x-axis, the coordinates of the image will be P'=(x,-y), then:

P=(-3,8)=(xp,yp)→xp=-3, yp=8→P'=(xp,-yp)→P'=(-3,-8)

Q=(-6,-4)=(xq,yq)→xq=-6, yq=-4→Q'=(xq,-yq)=(-6,-(-4))→Q'=(-6,4)

R=(1,1)=(xr,yr)→xr=1, yr=1→R'=(xr,-yr)→R'=(1,-1)

Brandon makes 4/5 of his free throw shots when he play. If he takes 45 shots how many is he expected to make

LUCKY_DIMON [66]

4/5 = 80%

80% of 45 is

.8 x 45 = 36

He is expected to make 36 of his shots

Pete's Pizza Parlor sells pizzas with two different types of crust (thin and hand-tossed) in three different flavors (cheese, pe

trapecia [35]

Answer:

The top tree correctly represents the sample space

Step-by-step explanation:

At the "root" of our tree, we can either have three branches for each of the flavors, or two branches for each of the types of crust. Here's how each of those branches continue:

If we start with the three branches for flavors, each branch will have two more branches for the types of crust. Working down the tree, I could start by choosing the pepperoni branch, and then continue to choose either thin or hand-tossed crust.
If we start with the two branches for crusts, each branch will have three more branches for the flavors. This option is represented as the first tree in the image, and in this case would be the correct choice.
