Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
Answer:
2root(58) == 15.23 miles
Step-by-step explanation:
Find distance between two points --> root( (x2 - x1)^2 + (y2 - y1)^2 ) = root (3^2 + 7^2) = root ( 58), as one unit is two miles then 2* root(58) = 15.23 miles.
If you find it is helpful plz give Brainliest
I think it would be the x+y=5,because how I learned it once you know y you can subtract y from 5 and get x.
Answer:
Step-by-step explanation:
Pythagorean Theorem : In a right triangle, square of hypotenuse is equal to the sum of the squares of the other sides.
Hence these sides represent a right triangle.
Hence this does not represent a right triangle.
This represents a right triangle.
