Answer is C.

Explanation:

So we have 100 data, aka numbers. So the mean would be
\dfrac{x_1 + x_2 + x_3 + \cdots + x_{100}}{100} = 267

where bunch of x represents those data.

So then x_1 + x_2 + \cdots + x_{100} = 267\cdot100, right?

So we have six outliers with mean 688. That would be
\dfrac{x_{i_1} + x_{i_2} + \cdots + x_{i_6}}6 = 688

So then x_{i_1} + x_{i_2} + \cdots + x_{i_6} = 688\cdot6

Now we don't know what i₁, i₂, etc, but we can just subtract outliers from set of observations and we will know that outliers will be gone in set of observation.

So that would be
(x_1 + \cdots + x_{100})- (x_{i_1} + \cdots + x_{i_6}) = 267\cdot100 - 688\cdot6

Now we know that there are now 94 remaining observations. So to find mean, we just divide whole thing by 94.

\dfrac{(x_1 + \cdots + x_{100})- (x_{i_1} + \cdots + x_{i_6})}{94} = \dfrac{267\cdot100 - 688\cdot6}{94} = \boxed{240.12766}

Which matches C.

Hope this helps.

A game store charges a monthly membership fee of $7.50, but then the charge to rent a game is only $1.00. Another store has no m
Eduardwww [97]

Answer:

6 games.

Step-by-step explanation:

Given that,

Monthly membership fee of store 1 is $7.5, but then the charge to rent a game is only $1.00

Another store has no membership fee, but that store charges $2.00 to rent a game.

Let there be n games needed to be rented each month for the total fees to be the same from either store.

Cost of first store = $7.50+$1.00n

Cost of another store = $2.00

If cost equals,

$7.50+$1.00n=$2

n=5.5 \approx 6

Hence, 6 games needed to be rented each month.
