A calculus student takes a 20-question, multiple choice test with 5 answer choices for each question. find the probability of ge

lisabon 2012 [21]

The probability would be 0.000017.

70% of the 20 questions is 14 questions correct. Using a binomial distribution for this, we have:

$_{20}C_{14}(0.2)^{14}\times (1-0.2)^{20-14}
\\
\\ \frac{20!}{14!6!}\times (0.2)^{14} \times (0.8)^6
\\
\\ \approx 0.000017$

Please help! How do I solve this

Monica [59]

Answer:

(x,y) --> (-1, -3)

Step-by-step explanation:

Solve by elimination...

2x - 3y = 7

4x + y = -7 (times 3; so -3y and 3y cancel out)

2x - 3y = 7

12x + 3y = -21

2x = 7

12x = -21

add together...

14x = -14

x = -1

plug x into one of the original equations and solve for y...

-2 - 3y =7

-3y = 9

y = -3
