Question

I need help/ 100 points for this please pls

Answer 1

1214

Explanation:

`\sf Probability\:of\:an\:event\:occurring = (Number\:of\:ways\:it\:can\:occur)/(Total\:number\:of\:possible\:outcomes)`

Total number of pizzas sold last week:

= 311 + 250 + 175 + 191

= 927

`\sf \implies \textsf{Probability of selling thick crust pizza} = (250)/(927)`

`\begin{aligned}\sf \implies \textsf{Expected value}& = \textsf{probabilty} * \textsf{number}\\ & = \sf (250)/(927) * 4500\\ & =\sf 1213.592233 \dots\\ & = \sf 1214\:(nearest\:whole\:number)\end{aligned}`

Answer 2

1214

Explanation:

311+250+175+191 = 927

then he sold 250 thick crust out of a total of 927 pizza crust

let x be the number of the thick crust expected to be sold out of the next 4500 pizza crust

Thick crust —————> Total

250 —————> 927

x —————> 4500

we have to solve this equation:

`(x)/(250) =(4500)/(927)`

`\Longrightarrow x=(250* 4500)/(927)`

`\Longrightarrow x = 1213.59223300971`
