The service time distribution describes the probability P that the service time of the customer will be no more than T hours. If

Molodets [167]

Answer: option d.

Step-by-step explanation:

You have the following formul given in the problem:

$p=1-e^{-mt}$

You know that:

The number of customers serviced in an hour by the technical support representative is 6 costumbers, therefore:

$m=6$

As the problem asked for the probability that a costumber will be on hold less than 30 minutes, we know that:

$t=0.5$

Substitute the values above into the formula.

Then, you obtain:

$p=1-e^{-(6)(0.5)}=0.95$ or 95%

Answer:

Step-by-step explanation:

Hello!

A systematic sample is a sampling type where, the population units are listed in a certain order, the first unit is randomly chosen from the first k number of units and then the subsequent units are selected in intervals of k. To calculate k, in case you know the population size, you have to divide the population size by the sample size (usually established based on previous information. Remember k is always a whole number.

a) k= pob/n= 4247/40= 106.175 ≅ 106

b) From the 106 individuals you have to randomly select the first unit. Then starting from it the next 39 individuals surveyed will be the +k

Using a random number calculator I've chosen the first individual to be surveyed as number 57 after that you have to add k= 106 to know wich are the next individuals to be sampled:

1) 57 11) 1117 21) 2177 31) 3237

2) 57 + 106= 163 12) 1223 22) 2283 32) 3343

3) 269 13) 1329 23) 2389 33) 3449

4) 375 14) 1435 24) 2495 34) 3555

5) 481 15) 1541 25) 2601 35) 3661

6) 587 16) 1647 26) 2707 36) 3767

7) 693 17) 1753 27) 2813 37) 3873

8) 799 18) 1859 28) 2919 38) 3979

9) 905 19) 1965 29) 3025 39) 4085

10) 1011 20) 2071 30) 3131 40) 4191

I hope it helps!

yarga [219]

Answer:$3207

Step-by-step explanation

A=p(1+r/100)^n

A=1000×(1+6/100)^20

A=1000×(1.06)^20

A=1000×3.207

A=$3207

Solve using the square root property.X^2=-12

Alla [95]

Answer:

x = ± 2i $\sqrt{3}$

Step-by-step explanation:

note that $\sqrt{-1}$ = i

x² = - 12 ( take square root of both sides )

x = ± $\sqrt{-12}$ = ± $\sqrt{4(3)(-1)}$ = ± 2i $\sqrt{3}$

The growth of a strain of bacteria can be modeled by the function graphed, where the x-values are the time in seconds and the y-

Andrew [12]

There are (A) 2.7 bacterias initially.

<h3>What is a function?</h3>

A function is an expression that establishes the relationship between the dependent and independent variables.
A function from a set X to a set Y allocates exactly one element of Y to each element of X.
The set X is known as the function's domain, while the set Y is known as the function's codomain.
Originally, functions were the idealization of how a variable quantity depends on another quantity.

To find the number of bacteria:

The graph shows that the function follows an exponential curve, and the starting point is at ( 0,2.7 ).
The starting number of bacteria is then 2.7.

Therefore, there are (A) 2.7 bacterias initially.
