The topic is critical path 12th grade and the subject is math of industry and government. Pls help and list the paths too ‼️‼️
Answers
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:
[tex](f\circ \: g)(x) = {3x}^{2} - 6[/tex]Step-by-step explanation:

The size of the square cut from each corner will be 1.369 inches. The correct option is C.
What is geometry?Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial properties such as figure distance, shape, size, and relative position.
Given that a box with no top that has a volume of 1000 cubic inches is to be constructed from a 22 x 30-inch sheet of cardboard by cutting squares of equal size from each corner and folding up the flaps.
The size of the square cut from each corner will be calculated as,
Volume = L x H x W
1000 = 22 x 30 x H
H = ( 1000 ) / ( 660 )
H = 1.538 or 1.369 inches
Therefore, the size will be 1.369 inches.

The correct answer will be option C Randomization of students in morning and afternoon classes.
What is psychology?Psychology is the scientific study of the mind and behavior, according to the American Psychological Association.
The only way to minimize this effect would be through randomization of students in morning and afternoon classes.
Doing so apply the factor of skill from an individual student to either time of day class greatly lessens the overall effect that it has on the results.
This therefore, minimizes the effect it has on the experiment itself, since the same students that have been studying in a certain time of day would be randomized and not have the same environment that they are used to.

Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three-point shot and gets three free throws, what is the approximate probability he will make all three shots?
Answers
The approximate probability that Ankit will make all three shots is 0.405 or 40.5%.
What is binomial distribution?A probability distribution known as the binomial distribution is used to characterize the number of successes in a certain number of independent trials, where each trial has only one of two potential outcomes (success or failure) and the chance of success is constant across all trials. For determining the likelihood of achieving a certain number of successes in a set number of trials, it is utilised.
Given, Ankit makes 74% of the free throws.
Using binomial distribution we have:
[tex]P(X=k) = (n C k) * p^k * (1-p)^{(n-k)}[/tex]
For k = 3 we have:
[tex]P(X=3) = (3 C 3) * 0.74^3 * (1-0.74)^{(3-3)}\\\\P(X=3) = 0.74^3[/tex]
P(X=3) ≈ 0.405
Hence, the approximate probability that Ankit will make all three shots is 0.405 or 40.5%.

3. y= -2
complete the steps used to solve a system of linear equations by substituting the value of y into one of the original equation s to find the value of x. what is the solution to the system
Answer:
x = 3.5
Step-by-step explanation:
We are given;
1. 3(4x - 7y = 28) -> 12x - 21y = 84
-2(6x - 5y = 31) -> -12x + 10y = 62
2. 12x - 21y = 84
-12x + 10y = -62
-----------------------
-11y = 22
3. y= -2
Since y = - 2, let's put -2 for y into the equation; 12x - 21y = 84
This gives;
12x - 21(-2) = 84
This gives;
12x + 42 = 84
12x = 84 - 42
12x = 42
x = 42/12
x = 3.5

Step-by-step explanation:
(1/2)^2 - 6(2 - 2/3)
First we get rid of the exponent 2 by muliplying the (1/2) two times.
(1/2)×(1/2) = 1/4
Now we have:
1/4 - 6(2 - 2/3)
Now we solve the equation in the other paraenthesis:
(2 - 2/3) = 1 1/3
Now we plug it back in:
1/4 - 6(1 1/3)
Now we mulitply the 6 with the fraction 1 1/3 in the paraenthesis:
6(1 1/3) = 8
Now we plug it back in:
1/4 - 8
Now finally solve this fraction:

-6x+9>7x+74
Answers
Answer:
Step-by-step explanation:
- 6x + 9 > 7x + 74
Treat them as being equal first.
Subtract 9 from both sides.
- 6x + 9 - 9 > 7x + 74 - 9
- 6x > 7x + 65
Subtract 7x from each side
- 6x - 7x > 7x - 7x + 65
- 13x > 65
Divide each side by -13
- 13x / -13 > 65 / -13
x < -5
So x hust be smaller than -5 meaning -6 works but -4 doesn't.
