Answer:

18

Step-by-step explanation:

When you do subtraction and addition you do it from left to right. So I did 16-3 which is 13, and I did 13+5 which is 18.

PLZ HELP HELP WITH ALL PART REALLY NEED HELP WITH THIS!!
Shalnov [3]
First, you should graph the points. For the first number, called the X-Axis, you should to the right or left, and for the second number, called the Y-Axis, you should go up or down.

To find the distance between Point A and Point C, you should simply just count the number of intersections between them (4).

Angle B is a right angle because if the triangle is bisected at B, it will leave a right angle on either side. Therefore, to label it, you should simply just draw a line through Point B all of the way to line (A,C).

The type of triangle you have drawn is an isosceles, because it has 2 equal angles and 2 equal sides.

We know both of the sides that are unknown will be the same because the triangle is bilateral. Then, we can use the bisection we made earlier to solve for the unknown sides using Pythagorean Theorem. Since earlier, we know the entire bottom is 4, we know half of the bottom is 2. We can also see that the height of the triangle is 2. We then plug those numbers into the Pythagorean Theorem (A^2*B^2=C^2) which makes the value of C^2=16. We then take the square root of C^2 and 16 to see that both unknown sides are 4.

Two less than 3/2 of a <br> number (x) is no more than 5 1/5
alexandr402 [8]
3/2 of a number could be 3/2x. two less than is thus 3/2x-2. no more than means less than or up to or ≤. finally,

3/2x-2≤5 1/5
3/2x≤26/5+10/5
3/2x≤16/5
x≤16/5*2/3
x≤32/15. or x ≤ 2 2/15

Consider an espresso stand with a single barista. Customers arrive at the stand at the rate of 28 per hour according to a Poisso
Snowcat [4.5K]

Answer:

The average number of customers in the system is 3.2

Step-by-step explanation:

The average number of customes in the system is given by:

L = \frac{\lambda^{2}}{\mu(\mu - \lambda)}

In which

\lambda is the number of arirvals per time period

\mu is the average number of people being served per period.

The number of arrivals is modeled by the Poisson distribution, while the service time is modeled by the exponential distribution.

Customers arrive at the stand at the rate of 28 per hour

This means that \lambda = 28

Service times are exponentially distributed with a service rate of 35 customers per hour.

This means that \mu = 35. So

The average number of customers in the system (i.e., waiting and being served) is

L = \frac{\lambda^{2}}{\mu(\mu - \lambda)}

L = \frac{28^{2}}{35(35 - 28)} = 3.2

The average number of customers in the system is 3.2
