Answer:3.67,1

Explanation:

TE = (O + 4T + P) / 6

where,

TE = Pert Expected Time Duration,

O = Optimistic estimate, =2

T = Typical estimate,=3

P = Pessimistic estimate=8

TE = (O + 4T + P) / 6

=(2+4*3+8)/6

3.6666=3.67

σ = (P – O)/6

=(8-2)/6

=1

Suppose 30% of a club are above 25 years old (M), 50% are between 21 and 25 (W) and 20% are below 21 (L). If all are exposed to
valina [46]

Answer:

The probability that a person selected at random has virus and is aged between 21 and 25 is 0.58.

Explanation:

let A be the event that the selected person has a virus.

let B1, B2 and B3 be the events that the selected perosn is  M, W and L accordingly.

the probabilities are given by:

P(B1) = 0.3

P(B2) = 0.5

P(B3) = 0.2

P(A|B1) = 0.65

P(A|B2) = 0.82

P(A|B3) =  0.5

probability of having virus and aged between 21 and 25 is given by:

[P(B2)*P(A|B2)]/[P(B1)*P(A|B1) + P(B2)*P(A|B2) + P(B3)*P(A|B3)]

= [(0.5)*(0.82)]/[(0.3)*(0.65) + (0.5)*(0.82) + (0.2)*(0.5)]

= 0.58

Therefore, the probability that a person selected at random has virus and is aged between 21 and 25 is 0.58.

Kangaroo Company had the following amounts on its balance sheet as of December 31, 2018: Inventory $325,000 Notes Payable 100,00
Gala2k [10]

Answer:

The balance of retained earning is $210,000

Explanation:

In this question, we have to apply the accounting equation which is shown below:

Total assets = Total liabilities + shareholder's equity

where,

Total assets = Inventory + Cash + Net Property, Plant, & Equipment + Accounts Receivable

= $325,000 + $150,000 + $600,000 + $30,000

= $1,105,000

Total liabilities = Notes payable + account payable

                        = $100,000 + $45,000

                        = $145,000

And, the shareholder equity = Common stock + retained earnings

Now put these values to the above formula

So, the answer would be equal to

$1,105,000 = $145,000 + $750,000 + retained earnings

$1,105,000 = $895,000 + retained earnings

So, retained earnings = $210,000
