Philip ran out of time while taking a multiple-choice test and plans to guess the last 4 questions. Each question has 5 possible
White raven [17]

Using the binomial distribution, it is found that there is a 0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

Considering that there are 4 questions, and each has 5 choices, the parameters are given as follows:

n = 4, p = 1/5 = 0.2.

The probability that he answers exactly 1 question correctly in the last 4 questions is P(X = 1), hence:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 1) = C_{4,1}.(0.2)^{1}.(0.8)^{3} = 0.4096

0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.

What is the slope of the line?<br> y +3 = -4(x+7)
Svetach [21]

Answer:

  -4

Step-by-step explanation:

Compare this to the form ...

  y -y1 = m(x -x1)

which is the point-slope form of the equation for a line. Matching the parts of the equation, you see that ...

  • y1 = -3
  • m = -4
  • x1 = -7

m represents the slope of the line. The slope is -4.

aniked [119]

Answer:

7 1/2

Step-by-step explanation:

How many times does 6 fully go into 45?

7 times.

7 times 6 is 42, so subtract that from 45 and you will get 3/6 left over after finding 7 as a whole number.
