The solution of the equation 34(2a − 6) + 12 = 25(3a + 20) + a will be negative 86.5.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

34(2a − 6) + 12 = 25(3a + 20) + a

Simplify the equation, then the value of the variable 'a' is given as,

34(2a − 6) + 12 = 25(3a + 20) + a

68a − 204 + 12 = 75a + 500 + a

68a − 192 = 76a + 500

Simplify the equation further, then the value of the variable 'a' is given as,

76a − 68a = − 192 − 500

8a = − 692

a = − 692 / 8

a = −86.5

The solution of the equation 34(2a − 6) + 12 = 25(3a + 20) + a will be negative 86.5.

Step-by-step explanation:

The least common multiple of 12, 20 and 6 is 60. Reducing the fractions to the denominator 60 we have:

[tex] \bold{ \dfrac{7}{12} + \dfrac{4}{20} - \dfrac{2}{6} = \dfrac{35}{60} + \dfrac{12}{60} - \dfrac{20}{60} } \\ \\ \bold{= \frac{35 + 12 - 20}{60} = \frac{27}{60} = \frac{9}{20} }[/tex]

If any addend is an integer, an I is placed as denominator and the same operation is done.

Therefore the solution to the difference of fraction comes out to be

The section A has total seats of, 25000, section B has got 14,700 and section C has got total 10,300 seats.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given equations in the question,

A + B + C = 50,000   (i)

42A + 24B + 18C = 1,588,200     (ii)

A = B + C    (iii)

Substitute value of A from (iii) to (i),

2B + 2C = 50000

B + C = 25,000   (iv)

Similarly, substitute value of (iii) in equation (ii),

42 (B +C) + 24B + 18C = 1588200

66B + 60C = 1588200

33B + 30C = 794100  (v)

Multiply 33 in equation (iv) and subtract from (v)

-3C = -30900

C = 10,300 seats.

Now,

B + C = 25000

B = 25000 - 10300

B = 14,700 seats.

And,

A = B + C

A = 10300 + 14700

Step-by-step explanation:

The length of each side of the given square is 3.306 yards.

A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles.

It can alternatively be explained as a rectangle with two neighboring sides that are of equal length.

In geometry, a square is a flat shape with four equal sides and four right angles (90°).

A square is a unique sort of parallelogram as well as an equilateral rectangle (an equilateral and equiangular one).

So, we have the area of the square as:

1.21 yards²

Area formula of square: A = s²

Now, calculate to find the length of the square as follows:

A = s²

1.21 = s²

s = 4/1.21

s = 3.306

The value of m in the diagram is 18°

What is a right-angle?

A right angle is an angle of 90°. When two rays intersect and form a 90˚ angle or are perpendicular to each other at the intersection, they are said to form a right angle.

A right angle is an angle that measures 90 degrees. It is the most commonly seen angle in our day-to-day life.

From the diagram, the two angles sum up to 90°

∠WZX + ∠XZY = ∠WZY

The slope of the line and a point on the line can be used to create the equation of a line. To better comprehend how the equation for a line is formed, let's learn more about the line's slope and the necessary point on the line. The slope of the line, which can be stated as a numeric integer, fraction, or the tangent of the angle it forms with the positive x-axis, is the line's inclination with respect to the positive x-axis. The coordinate system's point with the x coordinate and the y coordinate is referred to as the point.

Given points are (2,-5) and (6,-7).

The  point-slope form of a line is y - y₁ = m(x - x₁).

The slope of the line that passes through the points (2,-5) and (6,-7) is

Answer:

(- 3, - 7 )

Step-by-step explanation:

given

y = x - 4 ← substitute y = - 7 into the equation and solve for x

- 7 = x - 4 ( add 4 to both sides )

- 3 = x

then point is (x, y ) = (- 3, - 7 )

Answer:

(-3, -7)

Step-by-step explanation:

y=-7

y=x-4

-7 = x - 4  ==> since y=-7 and y=x-4, -7 = x-4

-7 + 4 = x - 4 + 4  ==> solve for x by adding 4 on both sides

-3 = x

x = -3

x=-3, y=-7 ==> (-3, -7)

Therefore, the slope of the line of best fit is 1.4.

To find the slope of the line of best fit, you will need to use the formula:

slope = (mean(x) * mean(y) - mean(x*y)) / (mean(x)^2 - mean(x^2))

where x represents the average daily temperature and y represents the total ice cream sales.

First, you will need to calculate the mean of x, the mean of y, the mean of x*y, and the mean of x^2.

The mean of x is (56.1 + 60.3 + 64.2 + 66.4 + 71.3 + 73.9 + 74.2 + 75.2 + 80.1 + 84.8) / 10 = 71.54

The mean of y is (107 + 116 + 120 + 122 + 125 + 130 + 132 + 135 + 141 + 152) / 10 = 128.6

The mean of xy is (56.1107 + 60.3116 + 64.2120 + 66.4122 + 71.3125 + 73.9130 + 74.2132 + 75.2135 + 80.1141 + 84.8*152) / 10 = 8707.7

The mean of x^2 is (56.1^2 + 60.3^2 + 64.2^2 + 66.4^2 + 71.3^2 + 73.9^2 + 74.2^2 + 75.2^2 + 80.1^2 + 84.8^2) / 10 = 6043.17

Plugging these values into the formula for the slope, we get:

The probability that the battery lasts between 12,000 and 14,000 miles is approximately 0.084.

The number of miles that a car can run before its battery wears out follows an exponential distribution with an average value of 11,000 miles. The probability that the battery lasts between 12,000 and 14,000 miles can be calculated as follows:

P(12,000 < x < 14,000) = P(x < 14,000) - P(x < 12,000)

To calculate the probabilities on the right-hand side of the equation, we can use the formula for the cumulative distribution function (CDF) of an exponential distribution:

F(x) = 1 - e^(-x/λ)

where λ is the mean value of the distribution. In this case, λ = 11,000 miles.

Plugging in the values and solving, we get:

P(12,000 < x < 14,000) = F(14,000) - F(12,000)

= (1 - e^(-14,000/11,000)) - (1 - e^(-12,000/11,000))

= e^(-12,000/11,000) - e^(-14,000/11,000)
