My Scando-Germanic friend, Odd Zahlen, often brings a die to class to answer multiple-choice final exam questions. Each multiple

Paraphin [41]

Answer:

$P(A=5)= 0.1366$

Step-by-step explanation:

From each multiple-choice question, there consists three answers to each;

So the probability of picking, the correct answer as they are uniformly distributed among the choices (a), (b), and (c) will be;

P(correct answer) = $\frac{1}{3}$

Now, to determine the probability of obtaining exactly 5 correct answers on a ten question examination using this method

Let use A as representative for the numbers of correct answers out of 10 questions that is being answered.

∴

$P(A=5)= [\left \ {{10} \atop {5}} \right.]$ $(\frac{1}{3}) ^5$ $(1-\frac{1}{3})^{10-5}$

$P(A=5)= [\left \ {{10} \atop {5}} \right.](\frac{1}{3}) ^5 (\frac{2}{3}) ^5$

$P(A=5)= 0.13657$

$P(A=5)= 0.1366$

A car driving at 20m/s accelerates at 3m/s2 for 3s. What is its final velocity? How far will it travel during this time?

-BARSIC- [3]

Answers:

Final velocity = 29 m/s

Distance traveled = 73.5 meters

========================================================

Work Shown:

The given data is

$v_i = 20 \text{ m}/\text{s} = \text{initial velocity}\\\\a = 3 \text{ m}/\text{s}^2 = \text{acceleration}\\\\t = 3 \text{ s} = \text{time duration}\\\\$

This leads to

$v_f = v_i + a*t\\\\v_f = 20 + 3*3\\\\v_f = 20 + 9\\\\v_f = 29\\\\$

The final velocity is 29 m/s.

----------

We can use that final velocity to find the distance traveled.

$x = 0.5*(v_i+v_f)*t\\\\x = 0.5*(20+29)*3\\\\x = 0.5*(49)*3\\\\x = 24.5*3\\\\x = 73.5\\\\$

The distance traveled is 73.5 meters.

----------

An alternative way to calculate the distance is to do this

$x = \frac{(v_f)^2 - (v_i)^2}{2a}\\\\x = \frac{(29)^2 - (20)^2}{2*3}\\\\x = \frac{841 - 400}{6}\\\\x = \frac{441}{6}\\\\x = 73.5\\\\$

Or you could do this

$x = v_i*t + 0.5*a*t^2\\\\x = 20*3 + 0.5*3*3^2\\\\x = 20*3 + 0.5*3*9\\\\x = 60 + 13.5\\\\x = 73.5\\\\$
