Using <em>statistical concepts</em>, it is found that the standard deviation of the probability distribution is of

When a constant is multiplied to each data in a variable, both the <u>mean and the standard deviation</u> are multiplied by the constant.
In this problem, the standard deviation, which is the square root of the variance, is of:

The price of each is of $1.5, hence:

sin45=5/x so x is 5/(sin45)
y is 5/(tan45)
question 5 then you just go x= (9sqrt(2)/2)/sin45
i don’t have a calculator rn so just plug it into it
