Answer:

It is a function.

Step-by-step explanation:

This relation <u>is</u> a function because it does not repeat any x values in the set of data points.

A function is a set of points where the input values, or x values, do not repeat themselves.

Hope this helps!

Answer:

Function

Step-by-step explanation:

Given is the relation with ordered pairs

${(0, 1), (3, 5), (2, 2), (–1, 4)}$

To check whether this relation is a function.

We find that in the given relation is domain is

${0,3,2,-1}$ and range is

{1,5,2,4}

We find that each element in the domain has a unique image in range.

Hence by definition of a function, this relation is a function.

cluponka [151]

Answer:

The correct answer is:

$\lambda=0.375 \ jobs \ per \ hour$
$\mu=0.5 \ jobs \ per \ hour$

Step-by-step explanation:

The given values are:

Service time varies,

Repair time = 2 hours

Standard deviation = 1.5 hours

Robotics uses per hour cost,

= $35

Company's cost per hour,

= $28

(a)

⇒ Arrival rate = Jobs per hours

then,

= $\frac{8 \ hours}{3 \ jobs}$

= $2.666 \ hours \ per \ job$

The jobs per hour will be:

⇒ $\lambda=\frac{1}{2.666}$

$=0.375$

(b)

⇒ Service rate = jobs per hour

then,

μ = $\frac{1 \ repair \ job}{2 \ hours}$

= $0.5 \ jobs$

Option D is the correct answer.
When comparing two congruent triangles, you can look at the order of the letters to see which ones are congruent.
In this case, YES = NOT
YE = NO since both YE and NO are the first two letters.

The total age of two sisters is 108 years

tester [92]

Answer:

7 : 5

Step-by-step explanation:

let the age of the younger be x , then the older is x + 18, thus

x + x + 18 = 108, that is

2x + 18 = 108 ( subtract 18 from both sides )

2x = 90 ( divide both sides by 2 )

x = 45

Thus younger is 45 and older is 45 + 18 = 63

ratio older : younger = 63 : 45 = 7 : 5
