How many solutions does the equation 4x 2 x 5 3 2x 4 have?.
The equation 4x + 2(x -5) = 3(2x - 4) does not have any solutions.
From the given equation:
We have 4x + 2(x -5) = 3(2x - 4)
By opening the brackets, we have:
2x+ 4x + - 10 = 6x - 12
6x - 10 = 6x - 12
By collecting the like terms, we have:
6x - 6x = -12 + 10
0 = -2
Thus, since there is no constant to a variable, then there is absolutely no solution at all.
An equation is deemed to be linear if the greatest power of the variable is consistently 1. It is also referred to as the one-degree equation. A linear equation with one variable typically has the form Ax + B = 0.
In this case, the variables x and A are the variables while only the variable B is a constant. A linear equation with two variables often has the form
Ax + By = C. The variables x and y, the coefficients A and B, and the constant C are present in this scenario.

If we spend Rs. 50 on two pens, as an example.
For four pens, it will cost us 100 Rs.
When the ratio x:y1 is constant, two values, x and y, are said to be inversely proportional to one another.
So, if a relationship between two variables, x and y, can be represented in the form y/x = k OR y = kx, it represents a proportionate variation.
Then,
If x rises, y will follow.
If x declines, y will follow.
So, we obtain:
When x is cut in half, y does as well.

What does variability mean in mean absolute deviation?.
The mean absolute deviation (MAD), a measure of variability, illustrates the typical distance between an observation's mean and its variation. MAD uses the data's original units to facilitate interpretation.
Greater values indicate a wider range of data points than the average. The term "variability" refers to how much a data collection varies from one constituent to another. Variability measures reflect the level and magnitude of change within the data collection.
The interquartile range and the mean average deviation are the two methods for calculating variability that are required by the requirements for sixth-grade pupils.
The majority of the data values are fairly near to the mean, as shown by a tiny mean absolute deviation. We can infer from a large mean absolute deviation that numerous data values are dispersed widely from the mean.

just designed a cloister (a rectangular garden surrounded by a covered walkway on all four sides). the outside dimensions of the garden are 12 feets by 8 feet, and the area of the garden and the walkway together are 252 square feet. what is the width of the walkway?
The width of the rectangular walkway is 3 feet around.
The walkway has a uniform width around the rectangle.
Let the width of walkway be x
The total length of the garden and walkway will be (12+2x) feet
The total width of the walkway and garden would be (8+2x) feet
Area of the garden and the walkway together are 252 square
Let’s express this mathematically:
(8+2x)(12+2x) = 252
Let’s open the brackets;
96+ 16x+ 24x + 4x^2 = 252
4x^2 + 40x + 96 = 252
4x^2 + 40x + 96-252 = 0
4x^2 + 40x - 156 = 0
Let’s divide all through by 10. We have;
x^2 + 10x -39 = 0
X^2 +13x-3x-39 = 0
x(x + 13) -3(x+ 13) = 0
(x-3)(x + 13) = 0
x -3 = 0 or x + 13 = 0
x = 3 or -13

Express your answers in terms of some, all, or none of the variables Q, R, the electric constant ϵ0 , and π, separated by a comma.
U=?
Volume(V) of a sphere = 4πr^3
Charge within a small volume 'dV' is given by:
dq = ρ(r)dV
ρ(r) = C/r^2
Volume(V) of a sphere = 4/3(πr^3)
dV/dr = (4/3)×3πr^2
dV = 4πr^2dr
Therefore,
dq = ρ(r)dV ; dq =ρ(r)4πr^2dr
dq = C/r^2[4πr^2dr]
dq = 4Cπdr
FOR TOTAL ENERGY CHANGE 'Q', we integrate dq
∫dq = ∫4Cπdr at r = R and r = 0
∫4Cπdr = 4Cπr
Q = 4Cπ(R - 0)
Q = 4CπR - 0
Q = 4CπR
C = Q/4πR
Therefore, in the total energy change with all the terms given, the value of constant C in terms of Q, π and R is [Q/4πR].

The probability that Maria succeeds at any given free-throw is 75%. She was curious how many free-throws she can expect to succeed in a sample of 10 free-throws.
She simulated 25 samples of 10 free-throws where each free-throw had a 0.75 probability of being a success.
Maria counted how many free-throws were successes in each simulated sample. Here are her results:
5: 0 successes
6: 5 successes
7: 8 successes
8: 6 successes
9: 6 successes
10: 1 success
We need to use her results to estimate the probability that she succeeds at fewer than 7 free-throws in a sample of 10 free-throws. First, find out how many successes were less than 7 (out of 25), which is 5. now, we divide 5 by 25 (5/25, formula being number/total attempts) and simplify into a decimal, which comes out to 0.2
The probability that she succeeds at fewer than 7 free-throws is 0.19
How to determine the probability?The table of values is given as
5: 0 successes
6: 5 successes
7: 8 successes
8: 6 successes
9: 6 successes
10: 1 success
From the above readings, the throws less than 7 are
5: 0 successes
6: 5 successes
So, the number of success is
Success = 0 + 5
Success = 5
The probability is then calculated as
P = Success/Total
So, we have
P = 5/(0 + 5 + 8 + 6 + 6 + 1)
Evaluate
P = 5/26
So, we have
P = 0.19
Hence, the probability is 0.19

Your local movie theater earns a total revenue of $40,000 per month when the price of a movie ticket is $8, and it earns a total revenue of $35,000 when the price of a movie ticket is $10.
When your local Internet service provider increased its monthly charge from $40 to $50, the number of subscribers fell from 2,000 to 1,800.
Last month, your local coffee shop charged $4 for a cappuccino and sold 150 cappuccinos. This month, it increased the price of a cappuccino to $5 and is on track to sell 120 cappuccinos.
As movie ticket prices rise, demand decreases or declines. When the cost of the neighborhood Internet service provider rises, demand likewise decreases. Demand decreases as cappuccino prices rise.
Define demand.Demand is the quantity of things that consumers are willing and able to purchase at various prices within a specific time frame. The term "demand curve" refers to the relationship between price and quantity demanded.

of the memory. Will
for music. He has already used 1.35 gigabytes
he have enough space to download a song that will use
0.12 gigabyte of
memory? Explain.
He has enough memory space to download a song that will use 0.12 gigabytes of memory
The memory capacity of new cell phone = 1.5 gigabytes
The memory capacity that already used = 1.35 gigabytes
The remaining space = The memory capacity of new cell phone - The memory capacity that already used
Substitute the values in the equation
Here we have to use the subtraction
The remaining space = 1.5 - 1.35
Subtract the terms
= 0.15 gigabytes
The size of the song = 0.12 gigabytes
We know 0.15 > 0.12
Hence, he has enough memory space to download a song that will use 0.12 gigabytes of memory
The complete question is
