2149 seats.  Since 2149 rounds down to 2100 at the nearest hundred, this is the greatest amount of seats possible in the stadium.  If there were 2150 seats, it would round to 2200 seats, so 2149 seats is the correct answer.

Hope this helps!

Answer:

A.

{b}^{2}  + 3b - 3 = 0

Step-by-step explanation:

andrew-mc [135]

The probability of getting two red lenses when two are selected will be 2/13.

<h3>What is probability?</h3>

The probability of favorable events to the total number of occurrences.

A box contains four red, three blue, and six green lenses.

Two lenses are randomly selected from the box.

Then the probability of getting two red lenses when two are selected if the first selection is not replaced before the second selection is made will be

The total number of the event will be

Total event = ¹³C₂

Total event = 78

Then the favorable event will be

Favorable event = ⁴C₁ x ³C₁

Favorable event = 4 x 3 = 12

Then we have

P = 12 / 78

P = 2/13

More about the probability link is given below.
