The expected value is given by:
E(x)= ∑x*p(x)
thus the expected value of calories will be given by:
E(x)=1/6*60+1/2*42+1/3*90
E(x)=10+21+30
E(x)=61
the answer is 61
Answer:
Step-by-step explanation:
If we have that worded expression, we can convert it into actual mathematical terms.
x to the one sixth power:
That to the power of 3:
Using exponent rules, since we have a power to a power, the powers multiply, so:
If we have a number to a fraction power, the denominator becomes the “find the (denominator) root of x.
So:
Hope this helped!
