Answer:
3000 liters
Step-by-step explanation:
To calculate the volume of the tin can, we can multiply its dimensions:
Volume = 2m × 1.5m × 1m = 3 cubic meters
Since a liter is equivalent to 0.001 cubic meters, we can convert the volume of the tin can to liters:
Volume (in liters) = 3 cubic meters × 1000 liters/cubic meter = 3000 liters
Therefore, the tin can can hold 3000 liters of kerosene oil.

Deduct 20% for taxes from the monthly gross income to get the net income (the amount made after taxes).
What is Andrew's monthly net income?
What is Lisa's monthly net income?
What is their total monthly net income?
Andrew's monthly net income is $65280.
Lisa's monthly net income is $60960.
The total monthly net income is $126240.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Andrew's monthly gross income.
= $81, 600
Lisa's monthly gross income.
= $76,200
Now,
Tax = 20%
So,
Andrew's monthly net income.
= 80/100 x 81, 600
= $65280
Lisa's monthly net income.
= 80/100 x 76,200
= $60960
Now,
Total monthly net income.
= 65280 + 60960
= $126240
Thus,
Andrew's monthly net income = $65280
Lisa's monthly net income = $60960
Total monthly net income = $126240

The Florida lottery has a game called Pick 4 where a player pays $1 and then picks a sequence of four
numbers 0-9 (e.g., 1234, 0389, 9020). If the four numbers come up in the order you picked, then you win
$3700.
a) The probability distribution for a player's winnings is shown in table.
b) The expected winnings for a player are $3.70.
What is probability distribution?
A probability distribution is a mathematical function that describes the likelihood of various variable values. Probability distributions are frequently represented using graphs or probability tables.
a) Since there are 10 possible digits for each of the four positions, there are a total of 10^4 = 10,000 possible sequences of numbers that could be drawn.
Only one of these sequences will be the winning sequence, corresponding to a probability of 1/10,000. If a player wins, the prize is $3,700. Therefore, the probability distribution for a player's winnings is shown in below table.
b) To find the expected winnings, we multiply each possible winning amount by its probability and add the products together:
E(Winnings) = (0) * (9999/10000) + (3700) * (1/10000)
= 37/10
= $3.70 (rounded to two decimal places)
Therefore, the expected winnings for a player are $3.70.

show me neat sketch of two graphs on the same set of axes that shows how the total amount repaid (T) depends on the number of months (N) for both of the instalment factors.
Answer:
Step-by-step explanation:
I can explain how the two graphs would look like.
If we are comparing two installment factors with respect to the total amount repaid (T) over time (N), we can plot two separate graphs on the same set of axes. The x-axis would represent the number of months (N) and the y-axis would represent the total amount repaid (T).
For each installment factor, we would plot a line that represents the total amount repaid over time. The shape and slope of each line would depend on the interest rate, the amount borrowed, and the number of payments per year.
The two lines would likely have a similar shape, but different slopes and intercepts. The slope of each line would depend on the interest rate and the amount borrowed, with steeper slopes indicating higher interest rates or larger amounts borrowed. The intercept of each line would depend on the amount borrowed and the number of payments per year.
To compare the two installment factors, we would look at the relative slopes and intercepts of the two lines. If one line has a steeper slope than the other, it would indicate that the total amount repaid increases more rapidly over time for that installment factor. If one line has a higher intercept than the other, it would indicate that the total amount repaid is higher at the beginning of the repayment period for that installment factor.
Overall, by plotting the two graphs on the same set of axes, we can visually compare how the total amount repaid (T) depends on the number of months (N) for both installment factors.

In a 100-meter race, the runner travels the 1st and 2nd 50-meters in time t1 and t2. Then t1>t2. So, the correct option is D.
During the first half , the runner has to start from the rest and will gain some velocity as he move further from start point, where as for the second half , as he already has the velocity required to run, he will complete the second half faster than first half.
Let us assume that V1 is the velocity , that the runner is having during the first half. V1 doesn't start as soon as he starts running, at first the body is in rest and velocity V1 starts increasing after he travels few distance.
And Let V2 be the velocity for the runner in second half , as he already have the velocity V1, there will be no delay to start the second half. So, second half takes less time than first half. This can be expressed as:
t2>t1

Classify the following functions on R as even, odd or neither: (Problem 1.4A) (a) fi(t)=I (b) f2(t) = t3-2t
For each of the functions in problem (1), find the even and odd parts of the function. (Prob- lem 1.4C)
a) f1(t) = 1 is a even function, the even part is simply 1/2, and the odd part is 0.
b) f2(t) = t^3 - 2t is odd function, the even part is t^3 - t, and the odd part is -t.
Part (a) asks us to classify the function f1(t) = I as even, odd, or neither. Here, I represents a constant, so f1(t) is a constant function.
A function f(t) is even if f(-t) = f(t) for all t in the domain of f. In other words, the function has symmetry about the y-axis.
A function f(t) is odd if f(-t) = -f(t) for all t in the domain of f. In other words, the function has rotational symmetry about the origin.
For a constant function, we have f(-t) = I = f(t) for all values of t. Therefore, f1(t) is even.
Part (b) asks us to classify the function f2(t) = t^3 - 2t as even, odd, or neither.
To determine whether f2(t) is even, odd, or neither, we need to apply the definitions of even and odd functions.
If f2(t) is even, then we have f2(-t) = f2(t) for all t.
If f2(t) is odd, then we have f2(-t) = -f2(t) for all t.
We can check these conditions as follows:
f2(-t) = (-t)^3 - 2(-t) = -t^3 + 2t
Since f2(-t) is not equal to f2(t) for all t, we know that f2(t) is not even.
We can also check if f2(t) is odd:
f2(-t) = (-t)^3 - 2(-t) = -t^3 + 2t = -f2(t)
Since f2(-t) = -f2(t) for all t, we know that f2(t) is odd.
To find the even and odd parts of a function, we use the following formulas:
even part of f(t) = (f(t) + f(-t))/2
odd part of f(t) = (f(t) - f(-t))/2
For f1(t) = I, the even part is (I + I)/2 = I/2, and the odd part is (I - I)/2 = 0.
For f2(t) = t^3 - 2t, the even part is (t^3 - 2t + (-t)^3 - 2(-t))/2 = t^3 - t, and the odd part is (t^3 - 2t - (-t)^3 + 2(-t))/2 = -t.

A young family is looking to buy a house and decides they need at least a 3/4-acre lot so there’s room for the kids and their dog Moose to play. Their agent plans to show them a house with a 30,000-sq-ft lot. Will she be wasting her time?
Answer: We can calculate the size of the lot in acres and then compare it to the minimum size of 3/4 of an acre that the family is looking for.
1 acre = 43,560 square feet
So, a 30,000 sq-ft lot is equivalent to:
30,000 sq-ft / 43,560 sq-ft/acre = 0.6864 acres
Since 0.6864 acres is less than 3/4 of an acre, the family's agent will be wasting her time by showing them the house with a 30,000 sq-ft lot. The lot is not big enough for the family's needs.

Hence, or otherwise, find the coordinates of the minimum point of the curve y =
x² + 4x – 7.
Answer: To find the minimum point of the curve y = x^2 + 4x - 7, we need to find the vertex of the parabolic function. The x-coordinate of the vertex can be found using the formula:
x = -b / (2a)
where a = 1 (coefficient of x^2), b = 4 (coefficient of x), and c = -7 (constant term). So, we have:
x = -4 / (2 * 1) = -2
The y-coordinate of the vertex can be found by substituting the x-coordinate into the original equation:
y = -2^2 + 4 * -2 - 7 = 4 - 8 - 7 = -11
So, the minimum point of the curve y = x^2 + 4x - 7 is located at the point (-2, -11).

4. [tex]y = (x + 2)^2[/tex]
Step-by-step explanation:
In this problem, we are asked to find the equations in their factored form of the graphed parabolas.
3. We can see that the parabola's vertex is at (3, -4). We can plug the coordinates of that point into the vertex form equation:
[tex]y=(x-a)^2 + b[/tex]
where [tex](a,b)[/tex] is the vertex of the parabola.
[tex]y=(x-3)^2 -4[/tex]
Then, we can expand the right side of the equation to an unfactored form.
[tex]y=x^2-6x+9 -4[/tex]
[tex]y=x^2-6x-5[/tex]
Finally, we can factor the right side of the equation.
[tex]\boxed{y=(x-3)(x-2)}[/tex]
4. First, input the vertex's coordinates into the vertex form equation.
[tex]y=(x - (-2))^2 + 0[/tex]
Then, simplify.
(Remember that subtracting a negative is the same as adding the positive)

Kareem is a software salesman. Let y represent his total pay (in dollars). Let x represent the number of copies of History is Fun he sells. Suppose that x and
y are related by the equation 90x+2500=y.
Answer the questions below.
Note that a change can be an increase or a decrease.
For an increase, use a positive number. For a decrease, use a negative number.
What is Kareem's total pay if he doesn't sell any copies of History is Fun?
What is the change in Kareem's total pay for each copy of History is Fun he sells?
?
70 8
The change in Kareem's total pay for each copy of Math is fun he sells is $90. Kareem's total pay if he doesn't sell any copies of Math is fun is $2500.
What is total pay?Total Pay means regular straight-time earnings or base salary, plus payments for overtime, shift differentials, incentive compensation, bonuses, and other special payments, fees, allowances or extraordinary compensation.
Given that, the equation 90x+2500 = y, represents the relation between number of copies (x) Kareem sells and total pay (y) he receives,
We are asked to find, Kareem's total pay if he doesn't sell any copies of History is Fun and the change in Kareem's total pay for each copy of History is Fun he sells,
So, from the equation, 90x+2500 = y,
If we compare this equation with the general equation of the line, i.e. y = mx+c, where m is the slope, which shows 'change', we will get m = 90.
Therefore, the change in Kareem's total pay is $90.
Now, the number of copies he is selling is shown by x, if he sells no copy, then x = 0,
Therefore, Kareem's total pay, for x = 0,
y = 2500+90(0)
y = 2500
Hence, the change in Kareem's total pay for each copy of Math is fun he sells is $90. Kareem's total pay if he doesn't sell any copies of Math is fun is $2500.

if we want to measure the magnitude of the orbital angular momentum and the projection of the angular momentum in
To measure the magnitude of the orbital angular momentum L and the projection of the angular momentum along a particular axis (say, the z-axis), we need to use the mathematical formalism of quantum mechanics.
In quantum mechanics, the orbital angular momentum L of a particle is an operator that acts on the wave function describing the particle's motion. Similarly, the z-component of the angular momentum Lz is also an operator.
The magnitude of the orbital angular momentum L can be calculated from the components of the angular momentum operator using the expression:
L^2 = L₁^2 + L₂^2 + L₃^2
where L₁, L₂, and L₃ are the x, y, and z components of the angular momentum operator, respectively. To measure the magnitude of the orbital angular momentum, we would need to measure the values of L₁ L₂, and L₃ and use them to calculate L^2.
The projection of the angular momentum along a particular axis (say, the z-axis) is given by the operator L₃. To measure the z-component of the angular momentum, we would need to measure the value of L₃ for a particular state of the system.
In practice, these measurements are often carried out using experiments involving the interaction of particles with magnetic fields. The behavior of the particles in the magnetic field allows us to infer information about the angular momentum of the particles.
The measurement of the magnitude and projection of angular momentum is an important part of many areas of physics, including quantum mechanics and solid-state physics.

The distance traveled in the time interval 0 ≤ t ≤ 6, given the velocity function v(t) = t^2 - 6t - 16, can be determined by calculating the definite integral of the absolute value of the velocity function over the given time interval. The result is 128 units of distance.
To find the distance traveled in the given time interval, we need to integrate the absolute value of the velocity function v(t) = t^2 - 6t - 16 over the interval 0 ≤ t ≤ 6. The reason for taking the absolute value is that distance is a scalar quantity and does not depend on the direction of motion.
Taking the integral of the absolute value of the velocity function, we have:
∫|v(t)| dt = ∫|t^2 - 6t - 16| dt
To evaluate this integral, we need to split it into intervals where the velocity function is positive and negative. The absolute value function essentially removes the negative sign from the expression inside the absolute value brackets.
Next, we find the points where the velocity function changes sign by setting v(t) = 0:
t^2 - 6t - 16 = 0
Solving this quadratic equation, we find t = -2 and t = 8 as the points where the velocity changes sign.
Now, we evaluate the integral over the intervals [0, 2] and [2, 6] separately, considering the absolute value of the velocity function within each interval.
∫|v(t)| dt = ∫(t^2 - 6t - 16) dt over [0, 2] + ∫(-(t^2 - 6t - 16)) dt over [2, 6]
Evaluating the definite integrals, we obtain:
(128/3) + (128/3) = 256/3
Therefore, the distance traveled in the time interval 0 ≤ t ≤ 6 is 256/3 units of distance, which is approximately 85.33 units of distance.

One reason to treat vectors as basis-independent quantities is to simplify vector expressions with- out resolving the vectors into orthogonal x, y, z or i k components.

True/False Explain: vr ax 0
The vector operations defined for a position vector a and a velocity vector b are vector addition and scalar multiplication.
Simplified Vector expression is (3u - 29) x u + (3u - 29) x v.
False, as the process that follows, solving for θ by dividing by the magnitude of v and taking the inverse sine, is only valid if v x a = 0.
1.28: The vector operations defined for a position vector a and a velocity vector b are vector addition and scalar multiplication.
1.29: Using the properties of the cross-product, the simplified expression is:
3u x u + 3u x v - 29 x u - 29 x v
Using the fact that the cross-product is distributive over vector addition, we can write this as:
3u x u + 3u x v - 29 x u - 29 x v = (3u - 29) x u + (3u - 29) x v
So the simplified vector expression is (3u - 29) x u + (3u - 29) x v.
1.30: False.
The given equation,
v x (a x R) = 0,
can be simplified to a scalar triple product,
(v x a) · R = 0.
Since the scalar triple product is equal to the determinant of a matrix formed by the three vectors,
this equation implies that either v x a = 0 or R = 0.
Therefore, the process that follows, solving for θ by dividing by the magnitude of v and taking the inverse sine, is only valid if v x a = 0.
The vector operations defined for a position vector a and a velocity vector b are vector addition and scalar multiplication.

The boxplot for the provide data is present in above figure. Median or central tendency of data is equals to 8.08. The lower and upper limits of outliers are 7.928 and 8.248 respectively.
The first task is to compute the median and the quartiles. And, in order to compute the median and the quartiles, the data needs to be put into the ascending order, as shown in the above table. Since the sample size n = 14 is even, we have that (n+1)/2 = (14+1)/2 =7.5, is not an integer value, the median is computing by taking the average of the values at the positions 7ᵗʰ and 8ᵗʰ, as shown below Median = (8.08 + 8.08)/2 = 8.08
Quartiles : The quartiles are computed using the table with the data in the asencending order. For Q₁ we have to compute the following position:
pos(Q) = (n+1)× 25/100 = 15×25/100 = 3.75
Since 3.75 is not an integer number, Q₁ is computed by interpolating between the
values located in the 3ᵗʰ and 4ᵗʰ positions, as shown in the formula above
Q₁ = 8.04+ (3.75 - 3) (8.05 - 8.04) = 8.0475
For Q3 we have to compute the following position:pos(Q₃) = (n + 1)× 75/100
= (14+1)×75/100 = 11.25
Since 11.25 is not an integer number, Q₃ is computed by interpolating between
the values located in the 11ᵗʰ and 12ᵗʰ positions, as shown in the formula below
Q₃ = 8.12 + (11.25 - 11) × (8.15 8.12) = 8.1275
The interquartile range is therefore
IQR = Q₃ - Q₁ = 8.1275 - 8.0475 = 0.08
Now, we can compute the lower and upper limits for outliers:
Lower = Q₁ - 1.5 x IQR = 8.0475 - 1.5×0.08 =7.928
Upper = Q₃ + 1.5 x IQR = 8.1275 + 1.5× 0.08 =8.248
and then, an outcome X is an outlier if X < 7.928, or if X > 8.248.
In this case since all the outcomes X are within the values of Lower = 7.9275 and Upper = 8.2475, then there are no outliers. The above boxplot is obtained.
