Yes, the OoO.

Oh, I see it. OoO is normally how I do it.

I loving hate math, the stuff my school makes us learn I will never use in life.

Well. It will make it loads easier to get a job when you get older. A good job anyway.

Doctor! I need 5/87 of hydrochloric acid from this 3.14159mL flask!

Pokémon. :P

If the catch rate (rate) = 3, bonus_ball = 2, bonus_status = 1.5, hp_current = 10 and hp_max = 153
work out how many tries (r) it will take for the probability to be 1 (100%)
(It's for the chance of catching ho-oh at lv 45 in heartgold.)

a=(((3x153-2x10)x3x2)/3x153)x1.5
a=(((459-20)x6)/459)x1.5
a=((439x6)/459)x1.5
a=(2634/459)x1.5
a=3951/459
a=8.6

Anyone wanna continue that one?

Teacher says this is for extra credit.

Which variable are we solving for?

You'll use the problem solving skills, though.

The last bit of that is the quadradic formula. You use it to solve factoring problems.

[Arcleader]

I think that's not even a solvable problem, just a bunch of formulas thrown together. There's barely a single number in there. There is only an exponent, a base, the bottom of the quadratic formula, and two geometric bases thrown in there.

This is literally a math question I have: "A tuning fork vibrates with a frequency of 220 hertz (cycles per second). You strike the tuning fork with a force that produces a maximum pressure of 3 pascals. Write a sine model that gives the pressure P as a function of the time t (in seconds). What is the period of the sound wave?"

I get P=3sine(440πt).

ITT: Dipstuffs who post google equations they don't know how to solve themselves.

Thickness of Library Books: The average thickness of books on a library shelf is 8.3 centimeters. The Standard Deviation is 0.6 centimeter. If 20% of the books are oversized, find the minimum thickness of the oversized books on the library shelf. Assume that the variable is normally distributed.

This is an actual question from the material we covered last week.

lol equations arent defined by numbers you know.
learn to look beyond 5th grade math.

Define "Oversized". Do you mean oversized the A) "Standard Deviation", or the B) "average"?

If A) then I think it's 9 cm.

If B) then I think it's 8.4 cm.
