Answer:
The expected value of the total sales projection is $24,773.
Step-by-step explanation:
Let sales be A,B and C respectively for each outcome.
Total Sales = A + B + C
E(Total Sales) = E(A + B + C)
We know that A, B and C are three mutually exclusive events as they all cannot be true at a given point time
E(Total Sales) = E(A) + E(B) + E(C)
= 0.3*285*32 + 0.4*490*47 + 0.3*750*57
= $24,773
Therefore, expected value of the total sales projection is $24,773.
A remote ranch has a cylindrical water storage tank. It has a vertical central axis, a diameter of 16 ft, the sides are 5 ft high, and it is full to the brim. The depth of this water is 4 ft. How much work (in ft-lb) would be required to pump all of the water over the upper rim? (Use the fact that water weighs 62.5 lb/ft3. Round your answer to the nearest integer.)
Answer and Step-by-step explanation:
Given: diameter = 16ft height = 5 ft. Depth = 4ft
Work =?
As we know that work = force x distance
W= distance x density x volume
W= ʃ04 (5-y) 62.5x ∏ (d/2)2dy (area = ∏r2 , r= d/2)
= 62.5 ʃ04 (5-y) ∏ (4y) dy
=62.5∏ ʃ04 (5-y) 4ydy
=62.5∏ ʃ04 20y-4y2dy
=62.5∏ |20y2/2 – 4y3/3|04
=62.5∏ |74.66|
=14659ft.lbs (approximately)
The work (in ft-lb) that would be required to pump all of the water over the upper rim is :
Given: Diameter = 16ft Height = 5 ft. Depth = 4ftWork =?
Formula:work = force x distance
W= distance x density x volume
W= ʃ04 (5-y) 62.5x ∏ (d/2)2dy (area = ∏r2 , r= d/2)
W = 62.5 ʃ04 (5-y) ∏ (4y) dy
W =62.5∏ ʃ04 (5-y) 4ydy
W =62.5∏ ʃ04 20y-4y2dy
W =62.5∏ |20y2/2 – 4y3/3|04
W =62.5∏ |74.66|
W =14659ft.lbs (approximately)
The work (in ft-lb) that would be required to pump all of the water over the upper rim is 14659ft.lbs

Why is the answer e and not c?
Step-by-step explanation:
π ∫₀¹ x² dx
This integral is obtained using disk method. Each disk has a volume of V = πr²t, so the radius is r = x.
The region is 0 ≤ y ≤ x, 0 ≤ x ≤ 1.
Revolved around the x-axis, the resulting shape is a cone.
If the shape were a paraboloid, the integral would have been:
π ∫₀¹ (x²)² dx
π ∫₀¹ x⁴ dx

2. Maya has a piece of fabric in the shape of a parallelogram. Its height is 12 feet and its base is 18 feet. She cuts the fabric into four equal parallelograms by cutting the base and the height in half. What is the area of each new parallelogram?
Answer:
54 square feet each
Step-by-step explanation:
So she has a parallelogram, 12 feet high and 18 feet long. She cuts them into fours, which is basically just cutting each number in half. 12÷2 is 6. 18÷2 is 9. Now each four parallelograms all have the measurements of 6 feet high and 9 feet wide. To find area, you would multiply and the base times height. 6 x 9 gives you 54 square feet.
8-4(2 - 5x) - 3(2x - 3) = 9 + 14x

Evaluate the function.
f(x) = 5-(7+x)+2, find f(3).
Answer:
-3
Step-by-step explanation:
For f = 5 - (7 + x) + 2, substitute x with 3.
f = 5 - (7 + 3) + 2
f = 5 - 10 + 2
f = -5 + 2
f = -3

A rolling pin has a diameter of 5 inches. If Lin rolled across the table and it made 35 rotations how far did it travel?
Answer:
2.22 rotations
Step-by-step explanation:
First, have to multiply the diameter by Pi. 5 * π = 15.7
15.7 is the circumference because the formula for circumference is d * π = c (diameter=d, circumference=c)
Next, 35/15.7 is 2.22.
You divide the 35 by 15.7 because if 15.7 inches is one rotation, then you want to see how many rotations fit into 35.
The rolling pin travels a distance of 549.5 inches in 35 rotations.
What is a sphere?A sphere has a spherical, symmetrical form. It is a three-dimensional solid with equal distances between each surface point and the center.
Given that, the diameter of the rolling pin is 5 inches.
The circumference of the rolling pin is:
5π
= 5×3.14
=15.7
Therefore, the rolling pin covers 15.7 inches in one rotation.
1 rotation = 15.7 inches
35 rotation = 35 ×15.7 inches
35 rotation = 549.5 inches
Hence, the rolling pin travels a distance of 549.5 inches in 35 rotations.

If the numerator of a fraction is increased by 3, the fraction becomes 3/4. If the denominator is decreased by 7, the fraction becomes 1.
What is the numerator of the fraction?
A. 2
B. 9
C. 16
I will give brainlist to the one who gets the answer right....
Answer:
B
Step-by-step explanation:
Assuming the denominator is 16 (to fit with the second part), 9+3 is 12 and 12/16 is 3/4.
If we take 7 from 16 we also get 9, which is thus 1.

Grains of sand are very small, there being about 3000 grains in one cubic centimeter (cm3) of sand. A cm3 is a small cube measuring one cm on each side and is about the size of your little finger from the fingernail onward. Given that there are one million cubic centimeters (cm3) in one cubic meter (m3), how many grains are there in 1 m3of sand
Answer:
The value is [tex]x = 3.000 * 10^9 \ grains[/tex]
Step-by-step explanation:
From the question we are told that
[tex]1m^3 = 10^6 cm^3[/tex]
And that
[tex]3000 \ grains \ of \ sand \ is \ in \ 1cm^3[/tex]
So the number of sand grain that is in [tex]1m^3[/tex] is mathematically evaluated as
[tex]x = 3000 * 10^6 \ grains[/tex]
=> [tex]x = 3.000 * 10^9 \ grains[/tex]

A researcher is studying psychological factors in artistic achievement among teenage boys. One variable he is particularly interested in is perseverance.
1. What information does a measure of variability for the variable perseverance convey?
2. What is the most common value for the variable perseverance among teenage boys?
3. How spread out are the values for perseverance among teenage boys?
4. What is the central tendency for the variable perseverance among teenage boys?
5. What is the average value for the variable perseverance among teenage boys?
Answer:
How spread out are the values for perseverance among teenage boys?
Step-by-step explanation:
1. What is the most common value for the variable perseverance among teenage boys? - This deals with MODE. Hence, this option is not correct because the problem does not deal with a specific value of the perseverance variable but about the variability of the perseverance variable
2. What is the central tendency for the variable perseverance among teenage boys? - This deals with the MEDIAN. However, since the problem is about determining dispersion, and not a central tendency, it is incorrect.
3. What is the average value for the variable perseverance among teenage boys? - This deals with the MEAN. Hence, it is not correct either.
However, since the given situation deals with a measure of variability for the variable perseverance conveys, the correct answer is "How spread out are the values for perseverance among teenage boys?" Because it measures how far are the observation away from the center.
