Answer:

C. x = -61/5

Step-by-step explanation:

7(x+5)+4(x+5) = 6x-6

First let's multiply the parenthesis parts.

7x+35 + 4x+20 = 6x-6

Combine like terms - combine all the x terms and the number terms. 7x + 4x = 11x, 35+20 = 55

11x + 55 = 6x - 6

Subtract 6x from both sides

5x + 55 = -6

Subtract 55 from both sides

5x = -61

x = -61/5

Answer:

The answer is "0.07404893".

Step-by-step explanation:

Applying the binomial distribution:

$n = 22\\\\p= 82\%=0.82\\\\q = 1-0.82 = 0.18\\\\$

Calculating the probability for not enough seats:

$=P(X>20)\\\\= P(21) + P(22)\\\\$

$= \binom{22}{21} (0.82)^{21}(0.18)^1+ \binom{22}{22} (0.82)^{22}(0.18)$

$=0 .06134598+ 0.01270295\\\\=0.07404893$

log(400) - log(4) can be turned into log(400/4), which is further simplified to log(100).
