When rolling a die (1) what's the probability of getting an even number in two successive throws??​

Mathematics

Answer:

when rolling a die you can end up getting 6 possibilities all together.

the number of even numbers in a die is 3.

therefore in the first throw you have a possibility of getting an even number at 0.5 or 50%.

and in the second throw you have a possibility of getting an even number at 0.5 x 0.5 which is 0.25 or 25%.

Hope this helps.

4. Find the distance between the two points. Round to the nearest tenth if necessary.
Archy [21]

Answer:

Distance = 7.8 units

Step-by-step explanation:

In coordinate geometry, the distance between the 2 points is given by

Distance = \sqrt{(x1-x2)^{2} + (y1-y2)^{2} }

where (x1,y1) and (x2,y2) are coordinates of the 2 points.

Above the 2 points given are, (-2,-1) and (3,5).

<em>x1 = -2 , y1 = -1 , x2 = 3, y2 = 5</em>

<em>Distance = \sqrt{((-2)-(3))^{2} + ((-1)-(5))^{2} }</em>

<em>Distance = \sqrt{61}</em>

<em>Distance = 7.8102 units</em>

To the nearest tenth, Distance = 7.8 units

Graph the function f(x) = -3/5x+8.
emmasim [6.3K]

Answer:

The y-intercept is at (0,8), so you can graph that point. Then the slope is -3/5. So the change in y coordinate divide the change in x coordinate is always -3/5. Thus 8-y/0-x=-3/5. You can choose any value for y and x as long as 8-y=-3. And 0-x=5. The point on the graph will just be (x,y) for the values you find.
