It's been a while since I've taken a math class and I'm stressed please help me out. The question is circled.
brilliants [131]
-3/2x

The rational expression would not be defined only when the denominator is divided by 0

That is:

2x =0

x = 0/2

x =0

Hence it would not be defined when x = 0.

Hope this helps.

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

Melani has $3,106.12 in her back account on Wednesday. On Thursday she deposited $85 .On friday she spent $8.25 for lunch. What
lesya692 [45]

Answer:

Melanie's account balance now is $3182.87.

Step-by-step explanation:

Given:

Amount of money in her account = $3106.12

Amount deposited on Thursday = $85

Amount spent for lunch on Friday = $8.25

We need to find the remaining balance in Melanie's account.

Solution:

Now we know that;

Remaining balance in her account is equal to Amount of money in her account plus Amount deposited on Thursday minus Amount spent for lunch on Friday.

framing in equation form we get;

Remaining balance in her account = \$3106.12 +\$85 - \$8.25=\$3182.87

Hence Melanie's account balance now is $3182.87.
