EGR 1400 FINAL EXAM WITH COMPLETE QUESTIONS
AND ANSWERS 2026 UPDATE
40 ohms - ANSWER Two resistors R1 and R2 are in parallel. If R1 = R2 = 80 ohms, what is the
equivalent resistance if these two resistors were combined into one?
10 - ANSWER In the circuit below, the resistance Rab is equal to ?
circuit har a 6 ohm resistor in series with an 8 ohm resistor that is parallel to another 8 ohm
resistor
5.1 - ANSWER A Detroit Lions football player kicks a football at an angle of 30º and a
velocity of 20 meters per second. How high will the ball go (in meters from the ground)?
14.5, window - ANSWER In a desperate attempt to get Juliet's attention, Romeo (who is 6
foot tall) throws a rock from 1 foot above his head at an angle of 45º with a velocity of 22
meters per second. Assuming that the rock hits the center of the window when it has reached
it's highest point, how high is the window (the center of the window, in meters)?
If Juliet, who just caught a glimpse of Romeo picking up the rock, excitedly ran to the window
and opened it 2 seconds after Romeo threw the rock, would the rock hit the window or Juliet?
13.04% - ANSWER (Poisson distribution) Depending on the color of car you purchase, you
may be at a higher risk for getting a speeding ticket. For Porsche's, a black car typically gets
1.4 speeding tickets, a white car typically gets 1.2 speeding tickets, and a red car typically gets
3.2 speeding tickets over a year period. If you purchased a red Porsche, what's the probability
of getting exactly one speeding ticket?
d - ANSWER A company that makes toy Elmo dolls has a chief inspector named Vrisken. In
three hours, an average of 2 (two) crates of dolls are rejected because they contain more than
4 randomly inspected faulty dolls (bad smell, discolored, doesn't speak, swears, etc...). What
is the probability of less than 2 crates of Elmo dolls being rejected in a three-hour period?
(Assume that this plant operates 24 hours per day, 7 days per week).
a.
1.83 %
b.
,27.07 %
c.
16.48 %
d.
None of these
e.
13.53 %
6/36 - ANSWER What is the probability of rolling a total of 7 (seven) on a pair of standard
dice?
27.78% - ANSWER What is the probability of rolling a total of 5 (five) on a pair of dice with
these sides:
(1, 1, 2, 3, 4, 4)?
95% - ANSWER What percentage of candidates have an age between 21 and 29 years from a
group of people with normally distributed ages with an average age of 25 years old and a
standard deviation of 2 years?
b - ANSWER Calculate the standard deviation for the data set: 1, 2, 2, 4, 7
a.
4.77
b.
None of these
c.
2.81
d.
3.20
e.
2.39
, a - ANSWER In C#, you can simulate rolling two dice by selecting a random number between
1 and 6 to represent each die roll and then adding them together to get the dice total. Let's
say that we developed a program to do this and we rolled the pair of dice 50 times and
recorded the results of each roll on a sheet of paper. Instead of using two die separately and
totaling them (which would result in a total between 2 and 12), can we just select one random
number between 2 and 12 and achieve the same experimental results for the 50 rolls as
rolling two die and adding them?
a.
No, it's not possible to get the same experimental results with one random number
b.
Yes, using the same scaling as before
c.
Yes, if the Visual C# code is written to scale the single random number between 2 and 12
d.
Yes, if the random number is selected using myRand.Next(2,13);
the Text property - ANSWER What property of a Label control would you need to set to
change the words displayed in the Label on the form?
5 - ANSWER What is the value of choice after the code below has finished executing? The
user entered a 4 in the text box, txtNumber.
int choice; choice = int.Parse(txtNumber.Text);
if ((choice > 6) && (choice < 4))
{
choice = 5;
} choice++;
b. txtAge - ANSWER Which of the following is the best name for a text box that will hold a
person's age within a Visual Studio .NET project, keeping in mind the recommended naming
conventions?
a.
