## Your Questions About Odd Calculator

Sandra asks…

## How do you get the values of the logarithms of the first 10 odd integers?

I don’t know how to do it?!

### admin answers:

Do you mean:

log(1)

log(3)

log(5)

log(7)

log(9)

log(11)

log(13)

log(15)

log(17)

log(19)

Use either an infinite Taylor series to approximate these values to a relatively close degree, or use a calculator and just get the answer directly.

Maria asks…

## What is the sum of all the odd numbers from 1-380?

the title explains it all. lol. 10 points to the first to give the sum and explain how they got it. thanks!

oh yeah, you have to answer by monday. i will not give 10 points to any entry that is later than monday.

### admin answers:

36243 is the answer and i just added all the odd numbers on a calculator

Robert asks…

## If you flip a coin 4 times in a row, what are the odds of getting heads every time?

What are the odds of getting heads 4 times in a row? does it go 1/2, 1/4, 1/6, 1/8 for 4 times in a row? Or does it multiply… 1/2, 1/4, 1/16, 1/256

### admin answers:

The odds of getting heads is 1/2 for each time you flip.

As a coin does not have memory of any previous flips, the odds are the same for each flip, consecutive or not.

1/2 x 1/2 x 1/2 x 1/2

1x1x1x1=1 | 2x2x2x2=16

or on a calculator

0.5 x 0.5 x 0.5 x 0.5 = 0.0625

1 / 0.0625 = 16

The odds of getting heads 4 times in a row is 1/16.

Helen asks…

## Behavior of a polynomial function without graphing?

Left and right hand behavior for f(x)=-2.1x^5 + 4x^3 -2x^2+1

It specifically reads in the instructions not to use a graphing **calculator**. How would I do this?

### admin answers:

Two things tell you the end behavior of a polynomial graph.

1) the degree: even degree tells you both tails go the same direction. Odds go opposite.

2) the sign on the first term: positive tails up on the right, and negative tails down on the right.

So you have a negative 5th degree. It will tail down on the right, with opposite direction, up, on the left.

If you are using limit notation, then as x-> infinity, y -> – infinity.

And as x-> – infinity, y -> + infinity.

Hoping this helps!

William asks…

## What are the odds of Tim Tebow of BOTH 316 and 31.6 yards?

Tebow throws for 316 yards and averages 31.6 yards on 10 completions. 4th quarter TV ratings were 31.6. He painted on his face John 316 before it got banned.

What are the odds?

### admin answers:

His passing yardage was 316 but he threw 21 passes for an average of 15 yards per attempt. This is the official stat.

Of course anyone that would take the total yardage and then compute the average based on the number of passes completed would be dishonest.

Tebow’s eye black never had John 3:16 while he was in the NFL, that was banned long before he ever came into the league, he did do it at the college level.

I think that anyone with a calculator can come up with all types of weird things if they wanted to.
