The statement that is true about the Random Variable X is P(X ≥ 4) = 0.522 , the correct option is (a) .
In the question ,
it is given that ,
the possible values of the random variable X is 1, 2, 3, 4, and 5 .
given that , 2 is twice as likely as 1 , that means
p(2) = 2p(1)
3 is one-third as likely as 2 , that means
p(3) = 1/3 p(2)
4 is four times as likely as 3 , which is
p(4) = 4/3 p(2)
and 5 is half as likely as 4 , that means
p(5) = 2/3 p(2)

a cylindrical tank 5 feet in diameter and 10 feet high is filled with oil whose density is 48 lbs/ft3 . how much work is required to pump the oil over the top of the tank?
The work required to pump the oil over the top of the tank is 1.5080 × 10⁶
Given:
We start as we often do: we partition an interval into sub intervals. We orient our tank vertically since this makes intuitive sense with the base of the tank at y=0 . Hence the top of the oil is at y=10 , meaning we are interested in subdividing the y -interval [0,10] into n sub intervals as
0 = y₁ < y₂ < ..... <yₙ₊₁ = 15
Consider the work Wi of pumping only the oil residing in the ith sub interval. The force required to move this oil is equal to its weight which we calculate as volume × density. The volume of oil in this sub interval is Vi=5²πΔyi ; its density is 48 lb/ft ₃ . Thus the required force is 4800πΔyi lb.
We approximate the distance the force is applied by using any y -value contained in the ith sub interval; for simplicity, we arbitrarily use yi for now (it will not matter later on). The oil will be pumped to a point 5 feet above the top of the tank, that is, to the height of y=15 ft. Thus the distance the oil at height yi travels is 15−yi ft.
In all, the approximate work Wi performed in moving the water in the ith sub interval to a point 5 feet above the tank is
Wi≈4800πΔyi(15−yi).
To approximate the total work performed in pumping out all the oil from the tank, we sum all the work Wi performed in pumping the oil from each of the n sub intervals of [0,10] :
W≈∑i=1nWi=∑i=1n4800πΔyi(15−yi).
This is a Riemann sum. Taking the limit as the sub interval length goes to 0 gives
W=∫3006240π(35−y)dy
=6240π(35y−12y2)∣∣10 0
= 48000π ≈ 1.5080 × 10⁶

The equation related to the number of hour and amount of water filled is
y=540x+10000.
What is equation?
An equation is a mathematical formula containing an equal sign. Equations often involve algebra. Algebra is used in mathematics when we don't know the exact number in a calculation. In its simplest form in algebra, the definition of an equation is a mathematical statement that two mathematical expressions are equal. For example, 3x + 5 = 14 is an equation where 3x + 5 and 14 are two terms separated by an equal sign. There are three main forms of linear equations: point-slope form, standard form, and slope intercept form.
Here given rate per hour = 540 and after 7 hours the pool contain 13780 gallon of water.
Here we need to write equation , then rate is equal to slope.
slope m = 540 .
The number of hours x and amount of water as y, Then,
=> [tex](x_1,y_1)=(7,13780)[/tex]
Now using equation formula,
=> [tex]y-y_1 = m(x-x_1)[/tex]
=> y-13780 = 540(x-7)
=> y-13780 = 540x-3780
=> y = 540x+13780-3780
=> y = 540+10000
Hence the equation is y=540x+10000.

in an equilateral triangle, the sides are 10 inches. what is the length of the height (the altitude)?
Answer:
An equilateral triangle has all side lengths the same, and all angles are 60 degrees. Using this we can split the triangle along its altitude to get two right triangles with a hypotenuse of length 10 and a base of 1/2 of the original length, so 5. Now we can either use the Pythagorean theorem (a^2+b^2=c^2) or the fact that it is a 30 60 90 triangle (angles measure at 30 60 and 90 degrees) Pythagorean theorem is probably easier.
It stated that the squares of the two legs of a right triangle add to the square of the hypotenuse. So a(the altitude)^2+5(the base)^2=10(the hypotenuse)^2
A^2+5^2=10^2
A^2+25=100
A^2=75
A=sqrt(75)
A=5*sqrt(3)
Final answer:
The altitude of an equilateral triangle with side length 10 is 5sqrt(3), or about 8.66

a team at a factory collected data on the number of nonconforming parts to construct an np-chart. fifteen samples of size 150 were collected. the team determined that the average fraction nonconforming was p
If a team at a factory collected data on the number of nonconforming parts to construct an np-chart then the average fraction has been mentioned below.
What is meant by the term average?The term "average" refers to the mean or centre tendency of a group of data. In other words, it serves as a gauge for the average or median value among a group of numbers. This may be computed by adding up all of the set's values and dividing the result by the total number of values. As an illustration, the average would be (1 + 2 + 3 + 4 + 5) / 5 = 3 if given numbers were 1, 2, 3, 4, and 5.
Average fraction may also be used to represent the expected value or usual outcome of a random variable. For example, if we flip a coin and assign a value of 1 to heads and a value of 0 to tails, the average of the potential outcomes.
How to solve?
= 0.2 and the standard deviation was s = 0.1.
Based on this information, the team can construct an np-chart to monitor the process and identify any potential issues.
The np-chart plots the number of nonconforming parts in each sample against the sample number.
The average fraction nonconforming (p) is indicated by a horizontal line on the chart, and any points that fall outside the upper and lower control limits, which are determined by the standard deviation (s), are considered to be out of control and require further investigation.
This allows the team to monitor the process and take corrective action if necessary to ensure that the number of nonconforming parts remains within acceptable limits.

What does having the sprinter gene mean?.
The sprinter gene means having Alpha-actinin-3(ACTN3) gene.
In the given question we have to find what does having the sprinter gene mean.
The ACTN3 gene is the recently identified "sprinters gene."
A gene, as we already stated, codes for a protein. Alpha-actinin-3 is designated by ACTN3. This protein, which can only be found in fast twitch muscle fibres, gives muscles their explosive ability.
The fast twitch muscle fibres of sprinters like Usain Bolt and other Olympic athletes would create a lot of alpha-actinin-3.
In order to summarise the genetic component, an individual has the ACTN3 gene if alpha-actinin-3 is present in muscle cells. They are therefore better suited for quick movements.
However, if a person lacks alpha-actinin-3, they have a variant copy of the ACTN3 gene. In other words, they are appropriate for long-distance activities.

the angle between two shortest sides of triangle is 85.1°..
We have provided that,
A garden has triangular shape.
let "AB" , "BC" , "CA" be sides of triangular shape garden and
we have the sides of triangle are 475 feet , 595 feet and 401 feet i.e AB = 475 , AC = 595 ,
BC= 401
we have to measure of angle between two shortest sides i.e angle between side AB and BC
let x degree be an angle between two shortest sides of triangle .
Using cosine rule ,
(AC)² = (BC)² + (AB )² - 2 AB×BC Cosx
=> (595)² = (401)² + ( 475)² - 2× 475 ×401 Cosx
=> 2(475×401) Cosx = (401)² + (475)² - (595 )²
=> 2 ( 475×401) Cosx = 32401
=> Cosx = 0.085
=> x = cos⁻¹(0.085) = 85.1°
Hence, the angle between two shortest sides of triangle is 85.1°

Which description of the graph of the linear inequality y ≥ 7x 4 is correct?.
The graph of the linear equality will be a solid line with a y-intercept of negative four and a slope of seven. Description of the graph is The graph will be shaded above the line.
The inequality is expressed as y ≥ 7x - 4
Now, just focusing on the equality sign
y = 7x - 4
y = 7x + (-4) --- (1)
Any linear equation in slope-intercept form has the following generic form:
y = mx + c --- (2)
so by equation 1 and 2
mx = 7x
m = 7
the equation y ≥ 7x - 4,
Put x = 0
y = 7(0) - 4
y = -4
As a result, the graph will look like a solid line with such a negative y-intercept of 4 and a seven slope. It will be shaded above the line on the graph.
