it gives you the formula, so all you have to do is plug in the coordinates

d =  \sqrt{ {( - 1 + 3)}^{2} +  {( - 1 - 1)}^{2}  }  \\ d =  \sqrt{ {(2)}^{2} +  {( - 2)}^{2}  } \\ d =  \sqrt{ 4 +  4  } \\ d =  \sqrt{8} \\ d = 2 \sqrt{3}  = 3.4641... \\  \\ d = 3.5

Hello,

spinner has 1 yellow, 2 red, 3 blue and 2 green sections. What is the probability of not getting a yellow?


to find the probability to not get a yellow you have to know the total of color which is

1+2+3+2=8

and its 1 yellow

So the probability of not getting a yellow is 1/8


hope this help

A city grid of Anytown, USA is shown on the grid below. The fire department is represented by quadrilateral RSTU. Another fire d
Alekssandra [29.7K]
Answer: option d. C (0,3), D (0,5).

Justification:

1) The x - coordinates of the vertices A and B are shown in the diagrama, They are both - 4, so the new vertices C and D must be in a line parallel to y = - 4.

2) The y-coordinates of the  vertices A and B are also shown in the diagrama. They  are equal to 3 and 5 respectively.

3) We can see that the new points C and D must be over a parallel line to y = - 4 and that their distance to the points A and B has to be the same distance of the point R and S to U and T.

That distance is 4, so the line may be y = - 7 or y = 0.

4) If the line is y = 7 the points C and D would have coordinates (-7,3) and (-7,5), but this points are not among the options.

5) If the line is y = 0 the points C and D would have coordinates (0, 3) and (0,5), which is precisely the points of the option d. That is the answer.

The equation of the line shown is y = 1/3x - 1

Because the slope is rise/run and in this case you rise 1 and run 3. And the y-intercept is -1 because that is where the line crosses the y-axis.

hope this helps :)
