The topic is critical path 12th grade and the subject is math of industry and government. Pls help and list the paths too ‼️‼️
Answer:
see below
Step-by-step explanation:
The difference between start and end times is the duration in each case.
The earliest start time is the latest of the earliest finish times of all predecessor tasks. These are computed working left to right.
The latest finish time is the earliest of the latest start times of all successor tasks. These are computed working right to left.
Where earliest and latest times are the same, the task is on the critical path. (It has no slack time.)
The above computations have been built into the attached spreadsheet. Here, predecessors and successors are handled manually. In appropriate scheduling software, they would be handled automatically by the specification of the task relationships.

Answer:
13. 68
14. y = 0.50x + 8
15. y = 25x - 15
16. y = 7x - 1
17. [tex]a_n = 4 + 6(n-1)[/tex]
Step-by-step explanation:
13. f(3) means plug in 3 for x.
f(3) = 7(3)² + 5 = 7(9) + 5 = 63 + 5 = 68
14. Write out what you know. 0.50 inches per hour is the rate of snowfall, or your m, or your slope. m = 0.50. If x is hours passed and y is inches of snowfall, then you also know that at x = 4, y is 10. Plug these into the standard linear formula: y = mx + b => 10 = 0.50(4) + b
Solve for b:
10 = 0.50(4) + b
10 = 2 + b
b = 8
Remember, x and y are variables, not constants, but m and b are always the same for some given function. So your answer is y = 0.50x + 8
15. Write out what you know. If x is hours passed and y is distance from home in miles, then we need to find the slope and y-intercept using what you're given. How do you find the slope? Use this: [tex]m (or slope) = \frac{y_2 - y_1}{x_2 - x_1}[/tex].
You have two points given: (3, 60) and (7, 160). So [tex]m = \frac{160-60}{7-3} = \frac{100}{4} = 25[/tex]
Now, just use either of these points to find b, or your y-intercept.
y = mx + b
Let's just use (3, 60); either one would work though.
[tex]60 = 25(3) + b[/tex]
60 = 75 + b
b = -15
To make the equation, use the values for m and b that you found.
m = 25 and b = -15, so y = 25x - 15
16. In y = mx + b, b is the y-intercept, but it's also how much the graph shifts up or down from its "original" position. I don't really want to explain this, but you can experiment with y = x + something (like try y = x + 1, y = x - 1, y = x, y = x + 3) and you'll see the pattern of what I'm talking about. To move y = 7x + 3 down 4 units, just subtract 4 from 3 to get -1: you will get y = 7x - 1.

WILL GIVE BRAINLIEST Pump it Up gym's daily revenue each can be modeled by R(x) = 5x where x represents the number of customers that visit the gym each day. The gym's daily costs can be modeled by the function C(x) = 2x + 150. Find the profit function P(x) if: P(x) = R(x) - C(x) P(x) = 7x +150 P(x) = 7x - 150 P(x) = 3x - 150 P(x) = 3x +150
Answer:
P(x) = 3x - 150
Step-by-step explanation:
Step-by-step explanation:
P(x) = R(x) - C(x)
Given:
R(x) = 5x
C(x) = 2x + 150
P(x) = 5x -(2x+150)
P(x) = 5x - 2x -150
P(x) = 3x - 150 <- Answer
Answer:
The profit function is P(x) = 3x-150
Step-by-step explanation:
Reason is R(x) = 5x
C(x)= 2x + 150
Plugin to P(x) = R(x) - C(x)
P(x) = 5x - (2x+150)
P(x) = 5x - 2x-150
P(x) = 3x-150

How 17 | 12. The Mad hatter is stocking up on tea for his
unbirthday parties. The market sells 5 boxes of tea
for $66 At this rate, how many boxes of tea can he
buy with $30?
Answer:
About 2.3 boxes of tea
Step-by-step explanation:
If we divide the price by the number of boxes, in this case, 66 / 5 we would get 13.2. So the means that each box would cost $13.20. So if we divide 30 by the cost of each box we would get approximately 2.3 boxes of tea. Hope this helps :)
A sampling frame a. is a list of population elements from which the sample will be drawn. b. is the list of population elements actually included in the sample. c. usually provides biased statistics. d. is a form of probability sampling.
Answer:
A. is a list of population elements from which the sample will be drawnStep-by-step explanation:
Sampling frame is the list of people or items from which a sample is taken.
Sampling is used because it is almost impossible to study entire population. Sampling allows us to find information about a population on the basis of results from a subset of the population, without studying every individual. It is easier and cost effective process.
A sampling frame refers to A. a list of population elements from which the sample will be drawn.
Sampling frame simply means the actual set of units from where the sample will be drawn.A sampling frame consists of all the items that are in the population. Therefore, a sampling frame is a list of population elements from which the sample will be drawn.Read related link on:

The product of 8 and the sum of a number x and 14
Answer:
8(x + 14)
Step-by-step explanation:
The term product signifies multiplication in mathematics. However, in order to find a product, we must have two or more terms to multiply. Because we are finding the product of 8 and the sum of a number x and 14, we will place the sum in parentheses to show they are being added together.
Using this knowledge, we are left with the sum in parentheses (x + 14) and the number 8 to multiply it.
To simplify, this can be written as 8(x + 14).

Tara looks up hotel room prices for a holiday. A hotel has a 25% off sale on its prices. A VAT charge of 20% must be added on at the end of the transaction after any discount. If the regular price of a room is £160 per night, how much will Tara pay for 7 nights?
Answer:
$1008Step-by-step explanation:
We begin by calculating the amount after the 25% discount
= regular price*0.75
=£160*0.75
=$120
We then continue by calculating the the amount that must be paid when 20% VAT is added
= 120*1.20
= $144
Now Tara is going to spend 7 nights
Hence she will have to pay
144*7= $1008
The The U.S.based motorcycle manufacturer says that it expects to build 140,000 motorcycles this year, up from 126.000 last year. Find the percent of increase in production.
Answer:
The us based motorcycle manufacturer says that it expects to build 140,000 motorcycles this year up from 126,000 last year.
This means the increased production is
144,000 - 126,000 = 18,000
The percentage change in production can
be found using the formula as listed below
PERCENTAGE INCREASE = change / initial × 100
Substitute the values we get
18,000/126,000 × 100
14.28 = percentage increase

-3(8n - 5) - 2n = 8n - 21
Answer:
Step-by-step explanation:
First you do the parentheses so the -3 x 8n= -24 and -3 x -5= 15
so it will look like this. -24n+15-2n=8n-21
Now combine like terms the -24n-2n.
-26n+15=8n-21 now subtract 8n now it will look like this
-34n+15=-21 now -15 from -21
-34n=-36
now if you want n by its self divide -34 and -36
