A six-sided die is rolled in a trial. What are the chances that the outcome is 2 or more?

1 answer:

5 0

To have the outcome of 2 or more, we can roll out a 2,3,4,5 or 6.

So, the chance of getting the outcome is 2 or more is 5/6

And, 5/6 is pretty much likely to happen. (around 80% or so)

4y+2y+10=50 <br>show your work<br>

denis23 [38]

Answer:

y = 20/3

Step-by-step explanation:

4y + 2y + 10 = 50

Combine like terms on the left side.

6y + 10 = 50

Subtract 10 from both sides.

6y = 40

Divide both sides by 6.

y = 40/6

Reduce the fraction by dividing the numerator and denominator by 2.

y = 20/3

In the first quadrant you start at (7,3) and move 5 unit left

AveGali [126]

Answer:

That would be (2,3)

Step-by-step explanation:

When we're moving left in the coordinate plane, we are subtracting the x-coordinate by how much distance we move.

In this case, 7-5=2, so the new x-coordinate is 2, but the y-coordinate doesn't change since we're going horizontally and not vertically.

Given the equation f(x) = (x + 3)2 – 8, fill in the blanks:

Neko [114]

Quadratic f(x) = (x -h)² +k has vertex (h, k) and axis of symmetry x=h. When k is negative, the number of real solutions is 2, because both branches of the function cross the x-axis.

In your equation, h = -3 and k = -8.

Axis of symmetry: x = -3
Vertex: (-3, -8)
Number of real solutions: 2
