Question:
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?
Question:
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
Question:
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)?
Question:
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?
Question:
,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?
Question:
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).

Question:
6/36
Answer:
What is the probability of rolling a total of 7 (seven) on a pair of standard dice?
Question:
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)?
Question:
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?
Question:
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.

Question:
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
