Choose the best definition for the following term: variable (1 point)
Answer:
The Meaning of term Variable is that Quantity Represented by small or Capital Alphabets of English whose value is not fixed.It can vary on different Situations.For example , Human diet can be called Variable.
In morning , you ate total of 0.25 Kg, in Afternoon you ate =0.50 Kg in total, and in the evening you ate total of 1 Kg.
So, if x is a variable of my Diet taken from Morning to evening, it has taken three distinct values, which are, x= 0.25, 0.50,1.
Here, x is a Variable, and 0.25,0.50 and 1 are Constant.

All of the following expressions are equivalent except _____. -4 - y -4 + y -y - 4 -y + (-4)
All of the expressions are equivalent except (b) -4 + y.
All the expressions involve adding -4 and - y in various orders, resulting in equivalent expressions due to the commutative property of addition.
However, the expression -4 + y is different because it combines the positive y term with the negative 4, resulting in - 4 + y.
The other expressions either have y added to -4 ( -4 - y) or have -4 added to y (-y - 4, -y + (-4)).
While addition is commutative, changing the order of the terms can affect the overall expression when dealing with negative terms.
So, while mathematically equivalent, the form of -4 + y stands out due to its structure.
Complete Question:
All of the following expressions are equivalent except _____.
(a) -4 - y
(b) -4 + y
(c) -y - 4
(d) -y + (-4 )

How many squares with sides that are 6 inches long are needed to cover a square with a side length of 30 inches without overlapping
Twenty-five squares with a side length of 6 inches are required to cover a square with a side length of 30 inches.
Explanation:To find out how many squares with sides that are 6 inches long are needed to cover a square with a length of 30 inches, you first need to find the area of each square.
The area of a square is found by multiplying the length of one side by itself.
So, the area of the smaller square is 6 * 6 = 36 square inches, and
the area of the larger square is 30 * 30 = 900 square inches.
Then, you divide the area of the larger square by the area of the smaller square:
900/36 = 25.
Therefore, 25 squares with sides of 6 inches are needed to cover a square with a side length of 30 inches.

Determine whether the given differential equation is exact. if it is exact, solve it. (if it is not exact, enter not.) (3x + 6y) dx + (6x − 8y3) dy = 0
The given differential equation (3x + 6y) dx + (6x − 8y3) dy = 0 is exact because its mixed partial derivatives are equal. To solve it, first integrate M with respect to x to get a function involving an unknown function of y, then compare it with N to determine the unknown function.
Explanation:To determine if the given differential equation is exact, we need to check if the partial derivative of M with respect to y is the same as the partial derivative of N with respect to x. In this given differential equation (3x + 6y) dx + (6x − 8y3) dy = 0, M = 3x + 6y and N = 6x - 8y3. First, compute the partial derivative of M with respect to y (∂M/∂y) which is 6, then the partial derivative of N with respect to x (∂N/∂x), which is 6 as well. Since ∂M/∂y=∂N/∂x, the given differential equation is exact.
To solve this exact differential equation, we integrate M dx, i.e., ∫M dx, to get ψ(x,y) =1.5x^2+6xy+h(y), where h(y) is an arbitrary function of y. Next, differentiate ψ(x,y) with respect to y, then compare the result with N: ψy=6x+dh/dy=6x-8y³. Solving for dh/dy gives dh/dy=-8y³, so integrating this gives h(y)=-2y⁴+C, where C is a constant. Therefore, the solution to the differential equation is ψ(x,y)=1.5x²+6xy-2y⁴=C.

How many positive integers not exceeding 1000 are not divisible by either 4 or 6?
There are 667 positive integers not exceeding 1000 that are not divisible by either 4 or 6.
Explanation:This is a question about number theory and involves the comprehension of divisibility. To identify the positive integers that are not divisible by either 4 or 6 and not exceeding 1000 is an application of the principle of inclusion and exclusion.
First, we need to figure out how many numbers up to 1000 are divisible by 4, which is 1000/4 = 250. Then, we look at how many numbers are divisible by 6, which is 1000/6 = about 166 (we only consider the whole numbers).
However, some numbers are divisible by both 4 and 6, so we have over-counted and need to correct for this. These would be the numbers divisible by the least common multiple (LCM) of 4 and 6, which is 12. There are 1000/12 = about 83 such numbers.
Thus, according to the principle of inclusion and exclusion, the total number of numbers divisible by 4 or 6 would be 250 + 166 - 83 = 333. The last step is to subtract this from the total number of integers from 1 to 1000, so the answer would be 1000 - 333 = 667.

If fixed costs are $561,000 and the unit contribution margin is $8.00, what is the break-even point in units if variable costs are decreased by $0.50 a unit?
Answer:
66,000 units
Step-by-step explanation:
Break-Even Sales (units) = Fixed Costs ÷ Unit Contribution Margin = $561,000 ÷ ($8 + $0.50) = 66,000 units
The break-even point in units after the decrease in variable costs is 66,000 units.
Given that the fixed costs are $561,000 and the original unit contribution margin is $8.00, we first calculate the original break-even point:
[tex]\[ \text{Original Break-even point in units} = \frac{561,000}{8} \][/tex]
[tex]\[ \text{Original Break-even point in units} = 70,125 \text{ units} \][/tex]
Now, since variable costs are decreased by $0.50 a unit, the new unit contribution margin becomes:
[tex]\[ \text{New Unit Contribution Margin} = 8 + 0.50 \][/tex]
[tex]\[ \text{New Unit Contribution Margin} = 8.50 \][/tex]
Using the new unit contribution margin, we calculate the new break-even point:
[tex]\[ \text{New Break-even point in units} = \frac{561,000}{8.50} \][/tex]
[tex]\[ \text{New Break-even point in units} = 66,000 \text{ units} \][/tex]
Therefore, the new break-even point in units, after the decrease in variable costs, is 66,000 units.

A domino consists of two congruent squares placed side by side. the perimeter of the domino is 60 units. what is the area of the domino, in square units?
Answer:
200
Step-by-step explanation:
So say the dominoes' short side is x. Then the long side is 2x, so altogether there is 6x. So 6x=60, so x=10. So the area is 10*(10*2), which is 10*20 which is 200.

It is desired to estimate the mean gpa of each undergraduate class at a large university. assume that the variance of the gpas is 1.44. how large a sample is necessary to estimate the mean gpa within 0.25 at the 99% confidence level
To estimate the mean GPA of each undergraduate class at a large university within a margin of error of 0.25 at a 99% confidence level, approximately 187 samples are needed.
Explanation:To estimate the mean GPA of each undergraduate class at a large university within a margin of error of 0.25 at a 99% confidence level, we need to determine the required sample size. In this case, we can use the formula for sample size determination, which is:
n = (Z^2 * σ^2) / E^2
Where:
n is the required sample sizeZ is the Z-score associated with the desired confidence level (99% corresponds to a Z-score of approximately 2.58)σ^2 is the variance of the GPAs (given as 1.44)E is the desired margin of error (0.25)Plugging in the values, we get:
n = (2.58^2 * 1.44) / 0.25^2
n ≈ 186.43
Therefore, we need a sample size of approximately 187 to estimate the mean GPA within a margin of error of 0.25 at a 99% confidence level.

The tables represent two linear functions in a system.
What is the solution to this system?
The solution to this system is (x, y) = (8, -22).
The y-values get closer together by 2 units for each 2-unit increase in x. The difference at x=2 is 6, so we expect the difference in y-values to be zero when we increase x by 6 (from 2 to 8).
You can extend each table after the same pattern.
In table 1, x-values increase by 2 and y-values decrease by 8.
In table 2, x-values increase by 2 and y-values decrease by 6.
The attachment shows the tables extended to x=10. We note that the y-values are the same (-22) for x=8 (as we predicted above). That means the solution is ...
... (x, y) = (8, -22)
Answer:
(8,-22)
Step-by-step explanation:
Table 1)
To form equation we will use two point slope form
[tex](x_1,y_1)=(-4,26)\\(x_2,y_2)=(-2,18)[/tex]
Formula :[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Substitute the values :
[tex]y-26=\frac{18-26}{-2+4}(x+4)[/tex]
[tex]y-26=-4(x+4)[/tex]
[tex]y-26=-4x-16[/tex]
[tex]y=-4x-16+26[/tex]
[tex]y=-4x+10[/tex] ---1
Table 2)
To form equation we will use two point slope form
[tex](x_1,y_1)=(-4,14)\\(x_2,y_2)=(-2,8)[/tex]
Formula :[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Substitute the values :
[tex]y-14=\frac{8-14}{-2+4}(x+4)[/tex]
[tex]y-14=-3(x+4)[/tex]
[tex]y-14=-3x-12[/tex]
[tex]y=-3x+2[/tex] ---2
Now we are supposed to solve 1 and 2
Substitute the value of y from 1 in 2
[tex]-4x+10=-3x+2[/tex]
[tex]8=x[/tex]
Substitute the value of x in 2
[tex]y=-3(8)+2[/tex]
[tex]y=-22[/tex]
Hence the solution to this system is (8,-22)
