Answer 1

Answer:

1120 pan Style pizzas.

Step-by-step explanation:

Given the information below:

$\left|\begin{array}{c|c}Type \:of \:Crust&Number \:Sold\\-----&-----\\Thin \:crust&313\\Thick \:crust&306\\Stuffed \:crust&155\\Pan \:style&301\\-----&-----\\Total &1075\end{array}\right]|$

The Relative Frequency of selling a pan style pizza =$\dfrac{301}{1075}$

Therefore, if Valentino's Pizzeria were to sell 4000 pizzas, the expected number of Pan style pizza sold will be:

Number of Pan Style Pizza Sold = Relative Frequency of pan Style Pizza Purchase X Total Number of Sales

$=\dfrac{301}{1075}X 4000 =1120$

They should expect to sell 1120 pan Style pizzas.
