2x + y = 1
3x - y = -6
---------------add
5x = -5
x = -5/5
x = -1

2(-1) + y = 1
-2 + y = 1
y = 1 + 2
y = 3

solution is (-1,3)

After arriving at the university student medical clinic, the waiting times to receive service after checking-in follow an expone
Marina CMI [18]

Answer:

6 students are served per hour.

45.12% probability a student waits less than 6 minutes.

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

f(x) = \mu e^{-\mu x}

In which \mu = \frac{1}{m} is the decay parameter.

The probability that x is lower or equal to a is given by:

P(X \leq x) = \int\limits^a_0 {f(x)} \, dx

Which has the following solution:

P(X \leq x) = 1 - e^{-\mu x}

mean of 10 minutes.

This means that m = 10, so \mu = \frac{1}{10} = 0.1

How many students are served per hour?

One student is served each 10 minutes, on average

An hour has 60 minutes

60/10 = 6

6 students are served per hour.

Calculate the probability a student waits less than 6 minutes.

P(X \leq x) = 1 - e^{-0.1*6} = 0.4512

45.12% probability a student waits less than 6 minutes.

L=wh/a(w+p) Make w the subject of the formula​
Anvisha [2.4K]

Answer:

w = lap/ h - la

Step-by-step explanation:

1 Multiply both sides by a(w+p)a(w+p).

la(w+p)=wh

2 Expand.

law+lap=wh

3 Subtract law from both sides.

lap=wh-law

4 Factor out the common term w.

lap=w(h-la)

5 Divide both sides by h-la.

lap/h - la = w

6 Switch sides.

w = lap/ h - la

2 x 5 x 18
10 x 18
180

</span>√3 x √2 x √8 = 
√6 x √8 = 
√48
√48 = 6 x 8 = 3 x 2 x 2 x 2 x 2 = 4√3

180 x 4√3 = 720√3

720√3 should be your answer

Liula [17]
The right answer for the question that is being asked and shown above is that: 

This can be answered using the Pythagorean Theorem.
h2 = a2 + b2
h = square root (8^2 + 5^2)
h = <span>square root (64 + 25)
h = </span><span>square root (89) in
h = 9.4 in

So the correct answer is 9.4 in given the dimension 5 inches and 8 inches.</span>
