Write and solve an equation, as follows:

-7y + 5(3+ny) = 3y + 15.  We are to find the value of 'n.'

-7y + 15 + 5ny = 3y + 15.

Subtracting 15 from both sides, we get    -7y + 5ny = 3y 

Grouping like terms, we get   5ny = 3y + 7y = 10y

Dividing both sides by 5y, we get n = 2   (answer)

New mean = 87.8

Mean = 85

Standard deviation = 14

Number picked = 49

Find:

Probability of choosing number

Computation:

Probability of choosing number = [New mean - Mean] / [Standard deviation / √Number picked]

Probability of choosing number <= [(87.8-85)]/[(14/7)]

Probability of choosing number = 0.9192
