Answer:

b. geometric

Step-by-step explanation:

The terms don't have a common difference, but they do have a common ratio: 2. A sequence in which terms have a common ratio is a geometric sequence.

___

Differences are ...

2/3 -1/3 = 1/3

4/3 -2/3 = 2/3 . . . . not the same

Ratios are ...

(2/3)/(1/3) = 2

(4/3)/(2/3) = 2

(8/3)/(4/3) = 2 . . . . ratios are common between pairs of terms

Given in the question, the section will follow

<u> Event Number of employees Classification</u>

A 120 Supervisors

B 50 Maintenance

C 1460 Production

D 302 Management

E 68 Secretarial

<u>Total 2000 all employees</u>

Probability that a person selected is in maintenance

P(M)= 50/2000 =1/40

Probability that a person selected in in secretarial

P(S)=68/2000 = 17/500

The probability that the first person selected is either in maintenance or in secretarial you add the two

1/40 + 17/500 = 59/1000

If 96 grams of carbon-14 are originally present in a fossilized plant at the present time, how much will remain after 17,000 yea

Elden [556K]

Well, you already have the decay model, so just plug that in

$\bf A=96e^{-0.000121\cdot 17000}\implies A=96e^{-2.057}$
