poizon [28]

Answer:

Total number of students in the college = 200 student

Step-by-step explanation:

Given:

Number of student make dean's list = 67 student

Percentage of student make dean's list = 33.5% of all student

Find:

Total number of students in the college

Computation:

Total number of students in the college = Number of student make dean's list / Percentage of student make dean's list

Total number of students in the college = 67 / 33.5%

Total number of students in the college = 67 / 0.335

Total number of students in the college = 200 student

Given three collinear points A,B,C with B between A and C, four different rays can be named using points AB, BA, BC, CB. How man
Dmitry [639]

Answer:

Given n collinear points, 2(n -1) or 2n - 2 rays can be named

Step-by-step explanation:

When we talk of collinear points, we mean points that lie on the same straight line.

For 3 collinear points we can have 4 rays

For 4 collinear points, let’s say ABCD

A B C D

The rays are AB BA BC CB CD and DC making a total of 6

For 5 collinear points,

A B C D E

The rays are;

AB BA BC CB CD DC DE ED which makes a total of 8

For 6 collinear points, we have;

A B C D E F

The rays are;

AB BA BC CB CD DC DE ED FE EF which makes a total of 10

So what pattern do we notice?

3 points 4 rays

4 points 6 rays

5 points 8 rays

6 points 10 rays

7 points 12 rays

So using the pattern

n rays = 2n - 2 rays or simply 2(n - 1) rays

Write the equation in slope-intercept form, identify the slope and the y-intercept.
SashulF [63]

Answer:

Slope is 2; y-intercept is (0,-6)

Step-by-step explanation:

Slope intercept form looks like 3y = 2x - 6

In the equation y=mx+b, M is always the slope, and B is always the y-intercept. Therefore if you look back at the problem the slope number should be in front of the x which makes it 2. Since the y-intercept is always b, y = -6.

Slope or m = 2; y-intercept is (0,-6)
