A ray is a line that has a begining point, but no end point
a ray is 1 dimentional, it only goes one direction, left and right
a plane is 2 dimentional and extends indefinitely
it goes left and right and up and down
think of it like this
you have a piece of paper with no height
you draw a line starting at a point on the paper and it goes infinitely in the other direction
the paper is a plane, the line on it that has a starting point is the ray
Answer:
3x cubed- 3x squared- 11x -22
Answer:
a) x = 1.52
b) s = 1.16
Step-by-step explanation:
We have that:
5 students watched 0 movies.
9 students watched 1 movie.
5 students watched 2 movies.
5 students watched 3 movies.
1 student watched 4 movies.
(a) Find the sample mean x.
Sum divided by the number of students. So

(b) Find the approximate sample standard deviation, s.
Standard deviation of the sample.
Square root of the sum of the squares of the values subtracted from the mean, divided by the sample size subtracted by 1. So

The correct answer to this question is <span>12.25 sq inches.

The largest rectangle is a square.
So if you divide 14" by 4 then you get 4 3.5" sides.
Area of a rectangle = L*W
<span>Area of a rectangle = 3.5 * 3.5</span>
<span>Area of a rectagle = 12.25 sq inches</span>
