Just divide 150 by 200 to get the percentage.
150/200 = .75
Move the decimal point two places to the right to make it a percentage.
.75 = 75%
150 miles is 75% of 250 miles.
10 5/12 can be turned into a improper fraction by multiplying 10 and 12. You get 120. Then you can add 5 and get 125/12.
THE ANSWER IS 125/12!
Answer:
D.) The expected value is 1.78
Step-by-step explanation:
The expected value of a probability distribution is evaluated using the formula.
Expected Value, ![E(X)=\sum^{n}_{i=1}x_iP(x_i)](https://tex.z-dn.net/?f=E%28X%29%3D%5Csum%5E%7Bn%7D_%7Bi%3D1%7Dx_iP%28x_i%29)
Therefore, from the given probability distribution, we have:
E(X)=(0*0.3)+(1*0.2)+(2*0.16)+(3*0.2)+(4*0.04)+(5*0.1)
E(X)=1.78
The Expected value of X is 1.78.
The correct option is D.
Answer:
The first one
Step-by-step explanation:
Since only the first session is $10, it wouldn't be 10x.
The second session is $5, and it will never be $10 again, so $5 sessions are unlimited which would be 5x.
So the answer is y = 10 + 5x
