I need help please with all these questions.(adsbygoogle = window.adsbygoogle || []).push({});

1. How many different paths on the diagram below will spell PASCAL?

* This diagram is a little wrong because i dont know how to do it on the forums, but anyways the letters should be spaced out so that they are in between each of the spaces.

P

A A

S S S

C C

A A A

L L

I count 16 if I do it manually, how do I do it as a combination my teacher never thought us how to do questions like these.

2. The mean age of 120 teachers in a school is 38 yrs old with a standard deviation of 5.3. Six of the teachers in the school are over 54 years of age. Is the distribution of the teachers’ age normal?

Heres what I did so can you please check it.

X~N(38,5.3)

=38+3(5.3)

=53.9

=0.15%

0.15% x 120=0.18

3. What are the possible values of n numbers if a set of n numbers always included its quartiles Q1, Q2, Q3?

3,7,11,15,19…..etc

tn=4n-1

Does this make sense? I think these are the right answers.

4. State the values of the first five powers of 11, starting with exponent 0, and compare these values to the entries in the first five rows of Pascal’s Triangle. Explain the relationship and why it fails for the next power of 11.

I am not sure what they are asking. But I think they want me to do this:

11^0=1 11^1=11 11^2=121 11^3=1331 11^4=14641 11^5=161,051

But now I don’t know what else to do so can you please help me.

So can anyone please help me with all these questions.
