An activity on a pert network has these time estimates: optimistic = 2, most likely = 5, and pessimistic = 10. what is its expected activity time?
The expected activity time for the given statement is = 5.33
What time is the PERT network expected to be active?The average amount of time required for an activity when it is repeatedly performed is known as the expected time. The weighted average of the three estimated times, i.e., the optimistic time, the most probable time, and the pessimistic time, is used in project management analysis to determine the expected time of activity.
The PERT system:A network model called the Program Evaluation and Review Technique (PERT) allows for randomness in the timing of activity completion. PERT was created in the late 1950s again for a massively labor-intensive Polaris project for the US Navy. It might shorten a lot of time and cost needed to finish a project.
According to the given information:optimistic = 2
most likely = 5
pessimistic = 10.
We will use the following formula to calculate the anticipated time for each activity in order to solve this problem:
Expected Time = (Optimistic Time + (4 x Most likely) + Pessimistic Time) / 6
Putting the values into formula:
= (2 + (4 x 5) + 10)/ 6
= (2 + 20 + 10) / 6
= 5.33

Find the L.S.A and T.S.A and volume of prism. whose sides are 3, 4 and 5 and height is 20cm
The lateral surface area of prism is 240cm2, total surface area is 250cm2 of prism , the volume of prism is 100cm2.
What is lateral surface of prism?
The lateral surface area of the right triangular prism (LSA) = ah + bh + ch (or) (a + b + c) h, where a, b and c are the bases of the rectangular faces and h is the common height or the total height of the prism. Also, (a + b + c) is the perimeter of the base (triangle).
What is total surface area of prism?
The total surface area of a right prism is T. S. A. = PH+2A, where P is the base perimeter, A is the base area, and H is the height of the prism.
What is volume of prism?
The formula for the volume of a prism is given by the product of the base and height of the prism. Thus, the volume of a prism can be given as V = B × H where V is the volume, B base area, and H height of the prism.
Given that,
The sides of prism are a=3cm, b= 4cm, c= 5cm
Also given that the height of the prism is h=20cm.
The lateral surface area of prism (LSA) = ah + bh + ch
Lateral surface area of prism = (3)(20)+(4)(20) +(5)(20)
Lateral surface area of prism = 60 + 80 + 100
Lateral surface area of prism = 240 cm2
The Total surface area of prism (TSA) = ph+2a
Total surface area = (LSA) + area of 2 bases
Total surface area = 240 + 2(5)
Total surface area = 250cm2
The volume of prism = base x height
Volume of prism = 5 x 20
Volume of prism = 100cm2.

9x + 2y = 5; y
1/15s - 2/3t = -2; s
Answer: y=[tex]\frac{5-9x}{2}[/tex]
s=-30+10t
Step-by-step explanation:
9x + 2y = 5; y
9x-9x+2y = 5-9x
2y=5-9x
y=[tex]\frac{5-9x}{2}[/tex]
1/15s - 2/3t = -2; s
(1/15s - 2/3t = -2)*15 ==> Get rid of fraction by multiplying both sides by 15

Answer:
3.3.1
A cylinder has a circular base.
3.3.2
As cylinders have circular bases, the formula for the area of the base of a cylinder should be the same as the formula for the area of a circle:
[tex]\boxed{\mathrm{Area = \pi r^2}}[/tex].
3.3.3
To find the volume of a cylinder, we can imagine stacking multiple circles on top of each other so that the height of the structure increases, and the shape becomes a cylinder.
This means that the volume of a cylinder is simply the area of the base circle multiplied by the height (h) of the cylinder.
∴ [tex]\boxed{\mathrm{Volume = \pi r^2h}}[/tex].
3.3.4
We can use the above formula to calculate the volume of the given cylinder, where:
• r = [tex]\mathrm{\frac{diameter}{2}}[/tex] = [tex]\frac{8}{2}[/tex] = 4 m
• h = 3 m
∴ [tex]\mathrm{Volume = \pi \times (4 \: m)^2 \times 3 \: m}[/tex]
[tex]= \mathrm{\pi \times 16 \:m^2 \times 3 \: m}[/tex]

Deondra is 1.35 meters tall. At 10 a.m., she measures the length of a tree's shadow to
be 35.25 meters. She stands 31.2 meters away from the tree, so that the tip of her
shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest
hundredth of a meter.
Answer:
If the length of a tree's shadow is 35.25 meters. The height of the tree to the nearest hundredth of a meter will be : 11.74m
Given:
Denora height=1.35 meters
Length =35.25 meters
Width =31.2 meters
Height of the tree=x
Proportion:
1.35 : 35.25 :: x : 31.2
Now let's determine the height of the tree:
35.25 - 31.2 / 1.35 = 35.25 / x
4.05 / 1.35 = 35.25 / x
Cross multiply
4.05x = 35.25 × 1.35
4.05x = 47.58
Divide both sides
x = 47.58 / 4.05
x = 11.74
In conclusion, if the length of a tree's shadow is 35.25 meters. The height of the tree to the nearest hundredth of a meter will be: 11.74m

Someone know this? The graph of g(x)is the graph of f(x)=x2 shifted 4 units left, vertically stretched by a factor of 3, then shifted 5 units up. What is the function rule for g(x)?
The function g(x) is given as: g(x) = 3 ( x + 4 )^2 + 5
Given data
f(x)=x2
shifted 4 units left
stretched by a factor of 3
shifted 5 units up
How to find the function rule for g(x)The function g(x) is formed from the function f(x) by the following moves:
Shifting 4 units to left
To shift the graph 4 units to the left is given by
f(x) = x^2
f(x) = ( x + 4 )^2
Stretching by a factor of 3
to stretch by a factor of 3 means multiplying by 3
f(x) = 3 * ( x + 4 )^2
f(x) = 3 ( x + 4 )^2
Shifting 5 units up
This movement is shows in the y axis and is represented as follows
f(x) = 3 ( x + 4 )^2 + 5
At this stage the function rule for g(x) is completed hence
f(x) = 3 ( x + 4 )^2 + 5 = g(x)
and
g(x) = 3 ( x + 4 )^2 + 5

The probability that the next two offspring will both be girls is 1/3.
To find P both children are girls
A: Event that both children are girls
A: {MM} and B: {MF, FM, MM} →→ P (A ∩∩ B) = {MM}
Probability that both are males, if we know one is a female =P(A/B)=P(A∩B)/P(B)
(P(A∩B)P(B))
Given S = {MM, MF, FM, FF}, we can see that: P (A) = 1414; P (B) = 3434; P (A ∩∩ B) = 1414
