Answer:
7 1/2
Step-by-step explanation:
I have no idea how to solve it I just guessed and got it right lol
1. We assume, that the number 800 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 800 is 100%, so we can write it down as 800=100%.
4. We know, that x is 8% of the output value, so we can write it down as x=8%.
5. Now we have two simple equations:
1) 800=100%
2) x=8%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
800/x=100%/8%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 8% of 800
800/x=100/8
(800/x)*x=(100/8)*x - we multiply both sides of the equation by x
800=12.5*x - we divide both sides of the equation by (12.5) to get x
800/12.5=x
64=x
x=64
now we have:
8% of 800 tons =64 Tons
I hope this helped!!
Multiply each payout by the corresponding probability and take the total:
E[X] = 0×0.5 + 5×0.2 + 8×0.15 + 10×0.1 + 15×0.05 = 3.95
Answer:
B
Step-by-step explanation:
Answer:
35
Step-by-step explanation:
We can assume the longer side is the hypotenuse because it is significantly longer than the other side.
From there, we can do Pythagoreans Theorem.
a^2+b^2=c^2
where can is the hypotenuse.
(12.75)^2+ b^2 = (37.25)^3
162.5625 + b^2 = 1,387.5625
-162.5625 -162.5625
b^2= 1,225
square root both sides.
b= 35
