Answer: 80% or 4/5
Step-by-step explanation:
so I don’t know how many numbers there are on this cube (a standard number cube has #1-6) but I’m going to go with 10 numbers (don’t know how this is possible but anyway-). I’ll edit my answer if needed.
10 numbers
10 (numbers) - 2 (#8 and #10) = 8 (possible numbers)
so 8/10 or 80%
reduced fraction: 4/5
percentage: 80%
fraction: 8/10

Using a tree diagram you can see that the probability is 1/(7^7) or 1/823543. This is about 0.0001%
Answer:
slopes is the ratio of the change in the y value over the change in the x value
Answer:

Explanation:
We have been given with the quadratic equation 
We have general formula to find the roots of a quadratic equation first we find the discriminant with formula

and after that to find the variable suppose x we have the formula

And general quadratic equation is

On comparing the given quadratic equation with genral quadratic equation we will have values
a=1, b=-7 and c=-6
After substituting these values in the formula we will get

After substituting in the formula to find x we will get
