nirvana33 [79]

Answer:

15

Step-by-step explanation:

PERT estimate is a measuring strategy that is based on a weighted average. It is used in measuring the uncertainty and risk via three estimates to determine an estimated likelihood for a project's cost or period of completion.

The formula is (O + 4M + P) ÷ 6

Where P is the most pessimistic = 29

M is the most likely = 12

O is the most optimistic = 10

Hence we have (10 + [4*12]+ 29) ÷ 6

= (10 + 48 + 29) ÷ 6

= 87÷6 = 14.5 ≈ 15

Rounded figure is equal to 15.

Hence the final answer to the question is 15

The manager of an electronics store projects that the store should achieve more than $21,000 in revenue from TVs and DVD players
Alina [70]

Answer:

380d + 530t > 21,000

Step-by-step explanation:

Each DVD costs $380, we can represent that as:

380d

Each TV costs $530, we can represent that as:

530t

We add these together to find the total profit:

380d + 530t

The manager predicts that whatever the total profit is, will be more than $21,000. So, we represent that as this:

380d + 530t > 21,000

And that is the final answer.

When Raphael solved the system below by using the method of elimination, he changed the second equation to -8x-2y=-2 what proper
galben [10]
For this case, what we are going to do is use the following property:
 Multiply an equation by a scalar.
 In this case, the scalar will be:
 k = -2
 We have then that equation 2 will be:
 k * (4x + y) = k * 1
 -2 * (4x + y) = - 2 * 1
 -8x-2y = -2
 Answer:
 The property that justifies this manipulation is:
 Multiply an equation by a scalar.
