Answer:

<em>A. Yes, because 8^2 + 15^2 = 17^2</em>

Step-by-step explanation:

In a right triangle, the hypotenuse is always longer than the other two sides.

The longest side in this triangle is 17. If this is a right triangle, then the legs are 8 and 15, and the hypotenuse is 17.

We use Pythagoras theorem

(one leg)^2 + (other leg)^2 = (hypotenuse)^2

8^2 + 15^2 = 17^2

If the equation above is true, then it is a right triangle. If it is not true, then the triangle is not a right triangle.

8^2 = 64

15^2 = 225

8^2 + 15^2 = 64 + 225 = 289

17^2 = 289

From 8^2 + 64^2 = 17^2, we get

289 = 289

Since the equation is true, it is a right triangle.

Answer: A. Yes, because 8^2 + 15^2 = 17^2

Answer:

a) 0.125

b) 7

c) 0.875 hr

d) 1 hr

e) 0.875

Step-by-step explanation:l

Given:

Arrival rate, λ = 7

Service rate, μ = 8

a) probability that no requests for assistance are in the system (system is idle).

Let's first find p.

a) ρ = λ/μ

$\frac{7}{8} = 0.875$

Probability that the system is idle =

1 - p

= 1 - 0.875

=0.125

probability that no requests for assistance are in the system is 0.125

b) average number of requests that will be waiting for service will be given as:

λ/(μ - λ)

$= \frac{7}{8 - 7}$

= 7

= λ/[μ(μ - λ)]

$= \frac{7}{8(8 - 7)}$

= 0.875 hour

(d) average time at the reference desk in minutes.

Average time in the system js given as: 1/(μ - λ)

$= \frac{1}{(8 - 7)}$

= 1 hour

(e) Probability that a new arrival has to wait for service will be:

λ/μ =

${7}{8}$

= 0.875

Which of the following relations has an inverse that is not a function?

sertanlavr [38]

Answer:

Option B is correct.

The relation which has an inverse that is not a function is :(1, 2), (1, 3), (4, 3)

Step-by-step explanation:

Inverse of a function is the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function.

Let f(x) ={(1, 2), (1, 3), (4, 3)}

To find the inverse:

Inverse of f(x)=g(x)= {(2, 1), (3, 1), (3, 4)}

Function states that a relation in which each input value has only one output value.

Since, g(x) is not a function because the input 3 has multiple output values,.

Therefore, the only relation which has an inverse that is not a function is :(1, 2), (1, 3), (4, 3)
