Let:
x - green marbles
4x - red marbles
x/2 - blue marbles

x+4x+\frac{x}{2}=33|\cdot2\\
2x+8x+x=66\\
11x=66\\
\boxed{x=6}\\\\
\boxed{4x=24}\\\\
\boxed{\frac{x}{2}=3}

Sheryl and Tess play basketball for the Tigers. The probability of Sheryl making a free throw is 0.25 and the probability of Tes
Hatshy [7]

Answer:

The probability is 0.17

Step-by-step explanation:

In this question, we are asked to calculate the probability that Sheryl makes a free throw and Tess not making a free throw

To answer this question, we must remember that the probability of an event happening and that same event not happening is 1. This will guide us to answer this question.

The probability of Sheryl making a free throw is 0.25

The probability of Tess making a free throw is 0.32, his probability of not making a free throw will be 1-0.32 = 0.68

Now we calculate the probability asked in the question as;

Probability of Sheryl making a free throw * probability of Tess not making a free throw

= 0.25 * 0.68 = 0.17

It's an ellipse centered at the origin: ezpz

take an x²
look at one of the x-intercepts
square that and slap it under the x²

put a "+" after it.

take a y²
look at one of the y-intercepts
square that and slap it under the y²
Put that all after the "+"
  
Last, put an "= 1" at the end and BAM!!!

Congratulations! You now have an equation!

\frac{x^{2} }{25} + \frac{ y^{2} }{9} = 1

Nata [24]

Answer:

\frac{4}{9}

Step-by-step explanation:

First, we gather the data:

The model is a single M/M/1 landing strip with \mu = \frac{2}{3}

This based on the assumption that service times are exponential.

Then, we must find the maximum rate such that w_{q} \leq 3

Using the M/M/1 table, we find that:

w_{p}  = \frac{\rho }{(\mu (1 -\rho)  } \\ \frac{\lambda }{\mu (1 - \lambda  } \leq 3

if and only if

\lambda\leq \frac{3\mu ^{2} }{(1 + 3\mu) }

=\frac{4}{9}
