of the answers. What is the experimental probability that you will guess exactly three out of five questions correctly?

Here's how you can do the experiment (simulation).
Since each question has four choices, numbered 1,2,3,4.
Then take a coin and throw it twice to represent your answer guess, with
HH=0
HT=1
TH=2
TT=3

Assume the correct answer is {1,1,1,1}, or any other set you decide to have.
Repeat this 5 times to get the 5 answers, and record the "correct" answers.

This constitutes ONE trial.  You can repeat the number of trials as you are required to do.
If the number of trials is a large number, you are better off writing a computer program, using Java, Excel, Perl, C, Basic, or any other language of your choice.

What's the largest 3-digit base 14 integer?
Mars2501 [29]
Base 10 has the ten digits: {0, 1, 2, 3, 4, 5, 6,7, 8, 9}

Base 11 has the digits: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A} where A is treated as a single digit number

Base 12 has the digits {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B}

Base 13 has the digits: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C}

Base 14 has the digits: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D}

The digit D is the largest single digit of that last set. So the largest 3-digit base 14 integer is DDD which is the final answer

Note: It is similar to how 999 is the largest 3-digit base 10 integer

Express the given linear equation in slope intercept form and identify the slope and y- intercept of -2x+7y=28
AlekseyPX
Slope-intercpet is y=mx+b where m=slope
b=y intercept
convert
-2x+7y=28
add 2x to both sides
7y=2x+28
divide both sides by 7
y=2/7x+4
slope=2/7
y-intercept=4 or the point (0,4)
