$We\ know\ that\\ Mean=\frac{Total\ Sum\ of\ observations}{Total\ number\ of\ observations} \\Here,\\Total\ Sum\ of\ the\ given\ observations\ are :\\9+9+2+8+9+8+7+8+3\\=63\\Total\ number\ of\ the\ given\ observations\ are :\\=9$

$Hence,\\Mean=\frac{63}{9}\\=7$

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $77. A season ski pass costs $450. The

n200080 [17]

Answer:

Step-by-step explanation:

Given:

Daily pass = $77
Season ski pass = $450
Skis = 20

77 + 20 = 97

450 + 20 = 470

Keep multiplying 97 with random numbers until it passes 470.

97 × 4 = 388

97 × 5 = 485

So, the skier will have to pay daily passes 5 times to be more expensive than the season pass.

Hope this helped.
