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

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

= $\frac{4}{9}$

<h3><u>Question:</u></h3>

Juan and raj cut up a banana to put on cereal. juan puts 1/7 of the banana on his bowl of cereal, and raj puts 2/5 of the banana on his bowl of cereal.

what fraction of the banana did juan and raj put on their cereal altogether?

a. 2/35 banana

b. 3/12 banana

c. 3/7 banana

d. 19/35 banana

<h3><u>Answer:</u></h3>

Juan and Raj altogether put 19/35 banana

<h3><u>Solution</u>:</h3>

Given that, Juan and Raj cut up a banana to put on cereal

$fraction\ of\ banana\ put\ by\ Juan = \frac{1}{7}\\\\fraction\ of\ banana\ put\ by\ Raj = \frac{2}{5}$

We have to find the fraction of banana put by Juan and Raj altogether

This means, we have to add both the fractions

$fraction\ of\ banana\ put\ altogether = fraction\ of\ banana\ put\ by\ Juan + fraction\ of\ banana\ put\ by\ Raj$

$fraction\ of\ banana\ put\ altogether = \frac{1}{7} + \frac{2}{5}\\\\\text{Cross multiply to simplify }\\\\fraction\ of\ banana\ put\ altogether = \frac{1 \times 5 + 2 \times 7}{7 \times 5}\\\\fraction\ of\ banana\ put\ altogether = \frac{5+14}{35}\\\\fraction\ of\ banana\ put\ altogether = \frac{19}{35}$

Thus they put $\frac{19}{35}$ of banana by Juan and Raj altogether

Which of the following statements is true?

Kay [80]

Answer:

B. 2^0 = 1

Step-by-step explanation:

here

A.) |-14|=14 & also |14|=14 so right ans |-14|=|14|

C.) 4.1*10-3=38 (4.1 * 10 = 41 & 41-3= 38) <u>38 > 0.041</u> but i dont know i think this is also true its also written as 38>= 0.041 maybe printing mistake

D.) squareroot of 20 = 4.4 something is > 4

and any no like 3^0= also 1,

4^0=1

5^0=1

ans is

B.) 2^0 = 1 is true

Answer:

5 + 32 = answer

Step-by-step explanation:

PEMDAS

parentheses

exponents

multiplication

division

addition

subtraction

the parts that are in "part" are what i solved in that step and what is in 'a number' is the answer to that step

"(2 + 3)" + 4 (to the power of 2) times "(5 - 3)"

'5' + "4 (to the power of 2)" times '2'

5 + '16' times 2

5 + "16 times 2"

5 + '32'

the answer is 5 + 32. I believe you can solve the last part so technically you solved the problem and I just helped a little. :D
