Based on the following information, what is the standard deviation of returns? state of economy probability of state of economy rate of return if state occurs recession .22 − .112 normal .25 .127 boom .53 .237

Step-by-step explanation:

Mean = 0.53*23.7% + 0.25*12.7% + 0.22*(-0.112)= 15.71%

standard deviation= sqrt(0.53*(23.7%-15.71%)^2 + 0.25*(12.7%-15.71%)^2 + 0.22*(-0.112-12.40%)^2)= 8.40%

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
