Answer:

A. 7.07 units

Step-by-step explanation:

Use the distance formula for coordinates:

d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2   }

Fill in the coordinates accordingly:

d=\sqrt{(1-(-4))^2+(-3-2)^2}

which simplifies down to

d=\sqrt{25+25}

which is of course

d=\sqrt{50}

Plug that into your calculator and you'll get the answer

A quiz in statistics course has four multiple-choice questions, each with five possible answers. A passing grade is three or mor
nekit [7.7K]

Answer:

a) 0.0016

b) 0.0224

Step-by-step explanation:

If every question has 5 possible answers, the probability of getting the correct answer by guessing would be 0.20. The probability of getting an incorrect answer would be 0.80.

a)Find the probability she lucks out and answers all four questions correctly.

To do this, Allison would have to guess right the first, second, third AND fourth answers. Therefore, we have to multiply the probabilities:

0.20 x 0.20 x 0.20 x 0.20 = 0.0016

The probability that she answers all 4 questions correctly is 0.0016.

b) Find the probability that she passes the quiz.

To pass the quiz, she has to have three OR 4 correct answers:

  1. The probability that she has 3 correct answers is: 0.20 x 0.20 x 0.20 x 0.80 (since she has to have 1 correct answer and 1 incorrect one) = .0064.
  2. We already calculated the probability that she guesses 4 answers correctly: 0.0016.

Now, we have to sum up these two scenarios:

0.0064 + 0.016 = 0.0224.

Thus, the probability that she passes the quiz is 0.0224
