slamgirl [31]

times both sides by 360 to solve for ydeg
180xrad/pi=ydeg
so

7/9pi rad
180(7/9pi)/pi=ydeg
140=ydeg

Identify the pair of events as dependent or independent. An odd-numbered problem is assigned for homework, and an even-numbered
S_A_V [24]

Hello!

As the homework and test are two separate things, selecting an odd or even number on either of them will not affect the probability of selecting an odd or even number on the other.

Therefore, this pair of events is independent.

I hope this helps!

Solve for the indicated variable
GrogVix [38]

Answer:

X_1=\frac{YX_2}{X_2-Y} \\\\

Step-by-step explanation:

\frac{1}{Y}=\frac{1}{X_1}+\frac{1}{X_2}

First subtract the 1/x2

\frac{1}{Y} - \frac{1}{X_2}=\frac{1}{X_1}

Next subtract the fractions on the left

\frac{X_2-Y}{YX_2}=\frac{1}{X_1}\\

Next Multiply by x1

\frac{(X_1)X_2-Y}{YX_2}=1\\

Next divide both sides by the remaining parts (not x1)

X_1=\frac{YX_2}{X_2-Y} \\\\
