Answer:

we have standard deviation of 12 so 298-322 would be 34.1% times 2 which is 68.2%. We also have 12 more in a lower region and we can use normal distribution to find that it would be 13.6% + 68.2%

Answer is 81.8%

How do you use the pythagoreum theorum again? i know the formula is a^2+b^2=c^2 but how do you use it. Use the example 15^2+20^2

kiruha [24]

It would be 225+400=c^2. square both sides to result in 25.

F = uv/u + v make u the subject

never [62]

I'm assuming that you mean

$\dfrac{uv}{u+v}$

because if you meant

$\dfrac{uv}{u}+v$

then u would simplify and you couldn't make it the subject.

Under this assumption, we start with

$F=\dfrac{uv}{u+v}$

We multiply both sides by $u+v$

$F(u+v)=uv$

We expand the left hand side:

$Fu+Fv=uv$

We move all terms involving u to the left and all terms not involving u to the right:

$Fu-uv=-Fv$

We factor u on the left hand side:

$u(F-v)=-Fv$

We divide both sides by $F-v$

$u=\dfrac{-Fv}{F-v}$
