Hello there. Sorry from last time.
What is the standard deviation of the possible outcomes? Roundyour answer to two decimal places.
<span>B.12.55</span>
X=number of plates
y=number of cups
4x+5y=25.25
7x+3y=25.50
Add the two equations together:
11x+8y=50.75
11x=50.75-8y
x=

Plug x into the first equation:
4x+5y=25.25
4(

) = 25.25

= 25.25

= 25.25
203-32y = 277.75
-32y=74.75
32y=-74.45
y=2.34 (rounded to nearest hundredth)
The price of a plate is $2.34
