A man weighing 80 kg gets into an elevator. The elevator starts moving upward with an acceleration of 2 m/s2. What is the reacti
maria [59]

The reaction force exerted by the floor of the elevator on the man is D.944 N

Step-by-step explanation:

When the elevator is accelerating upwards at 2 m/s² there occurs a fictitious force acting downwards to produce a downward acceleration of 2 m/s².

The formula to apply here is ;

Weight due to gravity=mg where m is mass of the man and g is acceleration due to gravity.

Due to additional downward acceleration the total acceleration downwards will be : 9.8+2 = 11.8 m/s²

The man weighs down on the elevator floor with a force of ;

F=m(a+g) where m is mass of man, a is acceleration

F=80( 9.8+2)

F=80(11.8)= 944 N

The reaction force by the floor of the elevator is thus 944 N

Stephanie has 60 tickets to the carnival.She used 3/4 of her 60 tickets to play games.Then she used 1/5 of her remaining tickets
Lera25 [3.4K]

Answer:

<h2>She gave her brother 6 tickets</h2>

Step-by-step explanation:

This problem is on fractional numbers.

given that she has 60 tickets

1.She used 3/4 of her tickets to play game

=(3/4)*60

=180/4

=45

She is left with (60-45)= 15 tickets

2. She used 1/5 of her remaining tickets for rides

    =(1/5)*15

   =15/5

   =3

She is left with (15-3)= 12 tickets

3. She gave half of her tickets to her brother.

  = (1/2)*12

  =12/2

 = 6

She gave her brother 6 tickets

You are to take a multiple-choice exam consisting of 64 questions with 5 possible responses to each question. Suppose that you h
damaskus [11]

Answer:

a) Expected score on the exam is 12.8.

b) Variance 10.24, Standard deviation 3.2

Step-by-step explanation:

For each question, there are only two possible outcomes. Either you guesses the answer correctly, or you does not. The probability of guessing the answer of a question correctly is independent of other questions. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

The variance of the binomial distribution is:

V(X) = np(1-p)

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

64 questions.

So n = 64

5 possible answers, one correctly, chosen at random:

So p = \frac{1}{5} = 0.2

(a) What is your expected score on the exam?

E(X) = np = 64*0.2 = 12.8

(b) Compute the variance and standard deviation of x. Variance =Standard deviation

V(X) = np(1-p) = 64*0.2*0.8 = 10.24

Variance 10.24

\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{64*0.2*0.8} = 3.2

Standard deviation 3.2
