Commercial formulas contain 20 calories per 30 mL. A 1-day-old infant was fed 45 mL at 0200, 0530, 0800, 1100, 1400, 1630, 2000,

Karolina [17]

Answer:

240 calories

Step-by-step explanation:

At each feeding, the baby received ...

45 mL × (20 calories)/(30 mL) = 30 calories

There were 8 feedings, so the total caloric intake was ...

(30 calories) × 8 = 240 calories

Write the equation of a circle with center (4, -5) and radius = square root of 13

Anon25 [30]

<h2>Hello!</h2>

The answer is:

The equation of the given circle is:

$(x-4)^{2}+(y+5)^{2}=13$

The equation of a circle is given by the following equation:

$(x-h)^{2} +(y-k)^{2}=r^{2}$

We are given the center point (4,-5) and the radius.

So,

Where:

$h=x=4\\k=y=-5\\r=\sqrt{13}$

Then, substituting into the circle equation, we have:

$(x-4)^{2} +(y-(-5))^{2}=(\sqrt{13})^{2}$

Hence, the simplified equation of the circle is:

$(x-4)^{2}+(y+5)^{2}=13$

Have a nice day!

A queue with a single server receives 50 requests per second on average. The average time for the server to address a request is

sdas [7]

Answer:

$P(X=k) = \displaystyle\frac{(2.5)^ke^{-2.5}}{k!}$

Step-by-step explanation:

This is a typical example where the Poisson distribution is a good choice to model the situation.

In this case we have an interval of time of 50 milliseconds as average time for the server to address one request and 50 requests per second.

By cross-multiplying we determine the expected value of requests every 50 milliseconds.

We know 1 second = 1,000 milliseconds

50 requests __________ 1000 milliseconds

x requests __________ 50 milliseconds

50/x = 1000/50 ===> x = 2.5

and the expected value is 2.5 requests per interval of 50 milliseconds.

According to the Poisson distribution, the probability of k events in 50 milliseconds equals

$\bf P(X=k) = \displaystyle\frac{(2.5)^ke^{-2.5}}{k!}$

The quotient of b and 2 minus 4 is at least 26. I need this ASAP

Pavlova-9 [17]

For this case we must express the following expression algebraically:

<em>"The quotient of b and 2 minus 4 is at least 26"</em>

So we have to:

The quotient of b and 2 minus 4, is represented as: $\frac {b} {2-4}$

We have different signs subtracted and the sign of the major is placed:

$\frac {b} {- 2}$

Thus, the expression is written as:

$\frac {b} {2-4} \geq26\\\frac {b} {- 2} \geq26\\- \frac {b} {2} \geq26$

ANswer:

$\frac {b} {2-4} \geq26$
