Answer:
Your Answer is 9/16
Answer:
True
Step-by-step explanation:
Deviation is how much data in the set differs from the mean or average of the set. This is true.
Answer:
y = 15
x = 30
Step-by-step explanation:
Since adjacent are equal, that means all 4 angles are equal to 90 degrees
6y = 90
Divide by 6
6y/6 = 90/6
y = 15
3x = 90
Divide by 3
3x/3 = 90/3
x = 30
Answer:
y = 15
x = 30
Step-by-step explanation:
Answer:
x = 22.5
Step-by-step explanation:
2x + 5 > 50.
We do inverse operations sooo:
2x + 5 - 5 > 50 - 5.
50 - 5 = 45.
Then we do 2x ÷ 2 and 45 ÷ 2.
45 ÷ 2 = 22.5.
To check our answer to see if its right we do 22.5 x 2 which equals 45. Then we do 45 + 5 which equals 50. So the sign is wrong it should be greater than or equal to.
Answer:
Step-by-step explanation: 2 plus 5
7 <50
The expectation to play the game is $2.5 and the fair price to play is $7.5.
The expectation is defined as the weighted average value of the random variable which is the product of the value of the random variable and its possibility.
Expectation= ∑P(win)*amount of win or loss of random variable
=∑x*P(x)
Here given that there are only two possible outcomes $5 and $10. And the possibility of every outcome is the same which is 0.5 as they occupy the same area.
As we know
Expectation= ∑P(win)*amount of win or loss of random variable
= 0.5(5-5) +0.5(10-5)
=0.5*0 + 0.5*5
=0+2.5
=$2.5
As fair price= expectation + cost of play
⇒fair price= $2.5 + $5
⇒fair price= $7.5
Therefore the expectation to play the game is $2.5 and the fair price to play is $7.5.
