Question

If, as is claimed, 23% of the population are news integrators, then how many people in our sample should we expect to be integrators

Answer 1

Answer:

45%

Step-by-step explanation:

45%

Step-by-step explanation:

The distance between two vectors, v_{0}v0 and v_{1}v1 , in which

v_{0} = (x_{0}, y_{0})v0=(x0,y0)

v_{1} = (x_{1}, y_{1})v1=(x1,y1)

Is given, in units on the coordinate grid, by the following formula:

D = \sqrt{(x_{1} - x_{0})^{2} + (y_{1} - y_{0})^{2}}D=(x1−x0)2+(y1−y0)2

So:

From vertex 1 to vertex 2

From (-4,-1) to (-4,5)

D = \sqrt{(-4 - (-4))^{2} + (5 - (-1))^{2}} = 6D=(−4−(−4))2+(5−(−1))2=6

From vertex 2 to vertex 3

From (-4,5) to (2,5)

D = \sqrt{(2 - (-4))^{2} + (5 - (5))^{2}} = 6D=(2−(−4))2+(5−(5))2=6

Total distance

From vertex 3 to vertex 4

From (2,5) to (2,-1)

D = \sqrt{(2 - (2))^{2} + (5 - (1))^{2}} = 6D=(2−(2))2+(5−(1))2=6

Total distance is 6+6+6 = 18 units

From vertex 4 to vertex 1

From (2,-1) to (-4,,-1)

D = \sqrt{(-4 - (2))^{2} + (5 24 units which equals political population of 45%

Each unit on the coordinate grid equals 45% of integrators
