Consider the following work breakdown structure: Time Estimates (days) Activity Precedes Optimistic Most Likely Pessimistic Start A,B - - - A C,D 44 50 56 B D 45 60 75 C E 42 45 48 D F 31 40 49 E F 27 36 39 F End 58 70 82 What is the probability that the critical path for this project will be completed within 210 days
Answer: the probability that the critical path for this project will be completed within 210 days is 0.99725
Step-by-step explanation:
Given that;
Work break down is;
Time Estimates (days)
Activity Precedes Optimistic Most Likely Pessimistic
Start A,B - - -
A C,D 44 50 56
B D 45 60 75
C E 42 45 48
D F 31 40 49
E F 27 36 39
F End 58 70 82
we know that;
Expected Time = ( Optimistic Time + ( 4 × most likely time) + pessimistic time) / 6
and
Variance = [( pessimistic time - Optimistic time) / 6 ]²
so
ACTIVITY EXPECTED TIME VARIANCE
A (44 + (4 × 50) + 56) / 6 = 50 ((56 - 44) / 6)² = 4
B (45 + (4 × 60) + 75) / 6 = 60 ((75 - 45) / 6)² = 25
C (42 + (4 × 45) + 48) / 6 = 45 ((48 - 42) / 6)² = 1
D (31 + (4 * 40) + 49) / 6 = 40 ((49 - 31) / 6)² = 9
E (27 + (4 * 36) + 39) / 6 = 35 ((39 - 27) / 6)² = 4
F (58 + (4 * 70) + 82) / 6 = 70 ((82 - 58) / 6)² = 16
ACTIVITY DURATION ES EF LS LF SLACK
A 50 0 50 0 50 0
B 60 0 60 30 90 30
C 45 50 95 50 95 0
D 40 60 100 90 130 30
E 35 95 130 95 130 0
F 70 130 200 130 200 0
FORWARD PASS:
ES = MAXIMUM EF OF ALL PREDECESSOR ACTIVITIES; 0 IF NO PREDECESSORS ARE PRESENT.
EF = ES + DURATION OF THE ACTIVITY.
CRITICAL PATH = PATH WITH THE LONGEST COMBINED DURATION VALUE AND 0 SLACK.
CRITICAL PATH = ACEF
DURATION OF PROJECT = 200
Now the probability
VARIANCE OF CRITICAL PATH = SIGMA(VARIANCE OF THE CRITICAL PATH) = 25
STANDARD DEVIATION OF CRITICAL PATH = SQRT(VARIANCE OF CRITICAL PATH) = 5
EXPECTED TIME = DURATION OF THE PROJECT = CRITICAL PATH = 200
DUE TIME = 210
Z = (DUE TIME - EXPECTED TIME) / STANDARD DEVIATION OF CRITICAL PATH)
Z = (210 - 200) / 5 = 2
Now form the Normal Distribution Table;
Z = 0.99725
Therefore, the probability that the critical path for this project will be completed within 210 days is 0.99725

Step-by-step explanation:
absolute values are always positive!!!
|-39| = 39 but since there is a minus sign outside the lines it is -39
|-44| = 44+5= 49
And 50 - 18 = 32 (|-18| = 18)

The resistance, R (in ohms), of a wire varies
directly with the length, L (in cm), of the
wire, and inversely with the cross-sectional
area, A (in cm2). A 500 cm piece of wire with
a radius of 0.2 cm has a resistance of 0.025
ohm. Find an equation that relates these
variables.
Answer:
The equation is: [tex]R = \frac{L}{A}[/tex]
Step-by-step explanation:
The resistance, R (in ohms), of a wire varies directly with the length, L (in cm), of the wire, and inversely with the cross-sectional area, A (in cm2).
This means that we want to find an equation for R, which is a fraction.
Since it varies directly with the length L, L is the numerator.
Since it varies inversely with the cross-sectional area, A is the denominator.
So the equation is:
[tex]R = \frac{L}{A}[/tex]
Answer:
R ∝ L/ A
R = K L/ A
0.025= 500K/0.126
the constant, K=6.3 X 10^-6
Step-by-step explanation:
Step 1
The resistance, R (in ohms), of a wire varies directly with the length, L (in cm), of the wire, and inversely with the cross-sectional
area, A (in cm2) is written mathematically as
R ∝ L/ A
Introducing the constant of proportionality,K, we have
R = K L/ A
So given that s 500 cm piece of wire with a radius of 0.2 cm has a resistance of 0.025 ohm.
We would First find area , since radius was given
Area = πr²
= 3.142 x 0.2²= 0.126cm²
Step 2
With our equation , R = K L/ A, puting all the necessary variables, we have
R = K L/ A
0.025= 500K/0.126
Solving for K
0.025= 500K/ 0.126
(0.025 X 0.126)/500 = K
K=6.3 X 10^-6
Brittany has $200 to spend on landscaping for her flowerbeds. She knows she wants to buy a $65 planter and a variety of flowering plants. What is the maximum number of flowers she can buy if each one costs $15? Make sure to write in the y=mx+b form.
Answer:
y = 15x + 65, or y = 15(9) +65
Step-by-step explanation:
So first, subtract $65 from $200 because Brittany is already using $65 for a plantar. For y = mx+b, $65 would be the b, because b is the fixed number, the number that cannot be changed. At this point, you are at y = mx + 65.
Now you are left with $135. Brittany wants to buy flowers with the remaining money. What you can do is division to see how many times $15 will go in $135 because with one flower = $15, we want to see the maximum number we can spend. If you do the division, you will see that $15 goes into $135 9 times, meaning you can buy 9 flowers, because each flower is $15, maxing out the remaining money you have.
In equation form, $15 would be the m, because m is what you multiply by and x is the independent variable, or the number of flowers Brittany will buy.
y = 15x + 65, or y = 15(9) +65

Ahmad wants to practice free-throws. He estimates the distance from the free-throw Line to the hoop and marks it with chalk. Ahmad’s estimate was 13.5 feet. The actual Distance should be 15 feet. Find the percent of error.
Answer: 10%
Step-by-step explanation:
The difference between his estimated and actual distance is 15 - 13.5 = 1.5
The percentage of error is the difference divided by the actual value.
1.5÷15 = 0.10
Converted to a percentage, it is 10%
Answer:
10%

What is the constant of proportionality for the relationship shown in the table? x 2 4 6 8 y 1 2 3 4
1/2
2
or not proportional
Answer:
1/2
Step-by-step explanation:
Given
x 2 4 6 8
y 1 2 3 4
Required
Determine the constant of proportionality (k)
The relationship between x and y is:
[tex]y = kx[/tex]
When y = 2, x = 4;
So, we have:
[tex]2 = k * 4[/tex]
[tex]2 = 4k[/tex]
[tex]4k = 2[/tex]
Make k the subject
[tex]k = \frac{2}{4}[/tex]
[tex]k = \frac{1}{2}[/tex]
Hence, the constant of proportionality is 1/2
Answer:
1/2

for a fixed voltage, the current in an electrical circuit varies inversely as the resistance in the circuit. If a certain has a current of 3.5 amps when the resistance is 110 ohms, find the current when the resistance is doubled.
Answer: 1.75 amps
Step-by-step explanation:
V (voltage) = I (current) · R (resistance)
V = 3.5 (110)
= 385
When Resistance is doubled, the current is cut in half.
V = I R
385 = I (2 · 110)
[tex]\dfrac{385}{220}=\text{I}[/tex]
1.75 = I
