Answer:
he /she must be patient as a teacher
Since we already know that there is a 25% chance to guess the correct answer to a multiple choice question, all we have to do is multiply .25 and 68 to get the expected amount of answers a student can possibly guess. We multiply .25 since it is the decimal form of 25% and 68 is our total questions.
.25 x 68 = 17
Therefore, a student can expect to guess 17 answers correct on a test with 68 multiple choice questions.
The formula is
A=p (1+r/k)^kt
A fund needed 30000
p Amount invested?
R interest rate 0.1
K compounded semiannual 2
T time 1 year
Solve the formula for p to get
P=A÷(1+r/k)^kt
P=30,000÷(1+0.1÷2)^(2×1)
P=27,210.88
First you are want to think of what two numbers will give you 72. It gives you 6, so you need to think of 6 times what will give you 72 (which is 12). Next you want to break down the 12, and you do the exact same thing you did with the 72. It gives you the number 3 so you need to find out 3 times what equals 12 (which is 4). Then you break down the 4 the same way. You have to do that to the 6 as well.
You continue to break down numbers until you can’t anymore.
