variance= n*p*(1-p)
.23*300*(1-.23)=53.1
standard deviation= sqrt(variance)
sqrt(53.13)= 7.3

Answer:
$5.75
Step-by-step explanation:
Joshua paid $9.10 for a bag and has $16.25 left
Now let's find out how much Joshua had before spending on a bag. To do this, we simply sum up the cost of the bag and how much Joshua had lefyt
9.10 + 16.25
=$25.35
Since Joshua and Shopping had the same amount, Shuping also had $25.35
To get the cost of the pen, we subtract the amount Shuping had left after purchasing the pen
This gives;
25.35 - 19.60
=$5.75
