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).

Thus, the probability we get one volleyball player and one basketball player is

$P_2=\dfrac{12}{23}\cdot \dfrac{22}{45}=\dfrac{88}{345}$

Identify the horizontal asymptote of f(x)=x^2+6x-9 over x-2

lora16 [44]

$\bf \cfrac{x^2+6x-9}{x-2}\qquad 
\begin{cases}
x^2\impliedby \textit{has a degree of 2}\\
x^1\impliedby \textit{has a degree of 1}
\end{cases}$

if the degree of the expression of the numerator is greater than that of the denominator, the rational expression has no horizontal asymptote.

Tems11 [23]

Answer:

5/11

Step-by-step explanation:

Black= 22 b+17 g

Brown= 4 b +18 g

Blonde= 25 b+ 10 g

Red= 21 b+ 15 g

Total number= 22+17+4+18+25+10+21+15= 132

Number of girls= 17+18+10+15= 60

Girls are 60/132= 2 × 2 × 3 × 5/ 2 × 2 × 3 × 11= 5/11 of all students
