So in the equation b - 9 + 6b = 30,

1 answer:

3 0

B - 9 + 6b = 30
You need to add all the b's up on the left side of the equation first. So it rewrites like this:
7b - 9 = 30
next you add 9 to each side to get 7b alone on the left side.
7b = 39
now divide both sides by 7 so that b is all by itself.
b = 5 4/7 or 5.57

Answer:

A) $\dfrac{11}{23}$

B) $\dfrac{88}{345}$

Step-by-step explanation:

A survey of 46 college athletes found that

24 played volleyball,
22 played basketball.

A) If we pick one athlete survey participant at random, the probability they play basketball is

$P_1=\dfrac{22}{46}=\dfrac{11}{23}$

B) If we pick 2 athletes at random (without replacement),

the probability we get one volleyball player is $\dfrac{24}{46}=\dfrac{12}{23};$
the probability we get another basketball player is $\dfrac{22}{45}$ (only 45 athletes left).
