Answer: The final step in solving the inequality -2(5 - 4x) < 6x - 4 would be to isolate x on one side of the inequality. In the previous step (-6 < -2x), we have -2x on one side of the inequality and -6 on the other. To isolate x, we divide both sides of the inequality by -2:

-6 ÷ -2 < -2x ÷ -2

Since dividing by a negative number reverses the inequality direction, we get:

3 > x

So, the final solution to the inequality -2(5 - 4x) < 6x - 4 is x > 3. This means that all values of x that are greater than 3 satisfy the inequality.

The fraction of the box she puts in each bowl is, 1/10

Fraction is a mathematical term, which represents the portion or sub-parts of the whole thing. Basically, It has two parts: numerator and denominator.

Numerator is a number which lies on the top side, it indicates the number of equal parts taken and denominator is on the bottom side, it indicates the equal parts of the whole number.

To find the fraction of the box that Evangeline puts in each bowl, we need to divide the total amount of nuts in the box by the number of bowls.

The amount of nuts she has is 3/5 of a box.

To find the amount of nuts in each bowl, we need to divide 3/5 by 6:

(3/5) ÷ 6

To divide by a fraction, we can multiply by its reciprocal:

= (3/5) ÷ (6/1)

= (3/5) x (1/6)

Multiplying across, we get:

= (3/5) x (1/6)

= 3/30

= 1/10

Therefore, Evangeline puts 1/10 of the box in each bowl.

The equation of a line perpendicular to line y = 8/3x-5 in slope-intercept form that contains point (-2, -2) is y = -3x/8 - 11/4.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁)

Where:

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

8/3 × m₂ = -1

m₂ = -3/8.

At data point (-2, -2), a linear equation of this line can be calculated in point-slope form as follows:

y - (-2) = -3/8(x - (-2))

y + 2 = -3/8(x + 2)

y = -3x/8 - 3/4 - 2

y = -3x/8 - 11/4

The distance between the points J=(-4, 0) and E = (4, 7) In the coordinate plane is, 10.63 units

The distance between two points in the coordinate plane can be calculated using the distance formula:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

Where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.

The given points

J=(-4, 0) and E = (4, 7),

we have:

x₁ = -4, y₁ = 0

x₂ = 4, y₂ = 7

Plugging in these values into the distance formula, we get:

d = √((4-(-4))² + (7-0)²)

  = √(8² + 7²)

  = √(64 + 49)

The prime factorization of 56 is the process of breaking 56 down into its prime factors. The prime factorization of 56 is 8 x 7, 2 x 2 x 2 x 7, or 2^3 x 7^1.

One way to calculate the prime factorization of 56 is to use a factor tree. To begin, find two numbers that multiply together to equal 56. The two factors that multiply together to equal 56 are 8 and 7. Since 8 and 7 are both prime numbers, they can be written as the prime factors of 56: 56 = 8 x 7.In mathematical terms, the prime factorization of 56 can be expressed as 56 = 2 x 2 x 2 x 7, where 2 is multiplied by itself three times and then multiplied by 7. This is because 56 can also be written as 2 x 2 x 2 x 7, which is the same as 8 x 7.The prime factorization of 56 can also be expressed as the product of the prime exponents: 56 = 2^3 x 7^1. Here, 2 is raised to the third power, and 7 is raised to the first power. This expression is equivalent to 8 x 7.In summary, the prime factorization of 56 is 8 x 7, 2 x 2 x 2 x 7, or 2^3 x 7^1.

The requried area of the shaded region is 4.56 square centimeters.

The area of a circle is given by the pie times square of the radius.

Area of circle = πr²

Here,
A right triangle is inscribed in a circle where the diameter of the circle is the hypotenuse of the right triangle,
So from the figure,
The area of the shaded region is given by the difference between the semi-circle LMN and the area of the right triangle LMN

The diameter of the circle is given by trig ratios,
sin 45 = 4/d

d = 4√2 So the radius will be d = 2√2

Now,
As hypotenuse is the diameter of the circle,
So LM = MN

Now,
Area of shaded region = area of semi-circle - an area of a triangle
Area of shaded region = πr²/2 - 1/2 × base × height

Area of the shaded region = 3.14 × [2√2]²/2 - 1/2 × 4 × 4
Area of shaded region = 4.56 cm²

Thus, the requried area of the shaded region is 4.56 square centimeters.

In statistics, p hat is used as an estimator of the population proportion (p) of a categorical variable. It is the sample proportion of the variable, which is calculated as the number of occurrences of a particular category in the sample divided by the total sample size.

The reason why p hat is used is that it provides an estimate of the unknown population proportion based on a representative sample. By using p hat, we can draw inferences about the population proportion with a certain level of confidence. This is important in hypothesis testing and confidence interval estimation, where we want to make statements about the population based on the information gathered from a sample.

Using p hat as an estimator of p is also beneficial because it has desirable statistical properties, such as being an unbiased estimator, having a sampling distribution that approaches normality, and having a known standard error.

(1) The predetermined overhead rate is $10.50 per direct labor-hour.

(2) Mr. Wilkes' total job cost is $960.

(3) Speedy Auto Repairs would have charged Mr. Wilkes $1344 for the job.

1) To compute the predetermined overhead rate, we need to add the fixed and variable overhead costs, and then divide by the estimated direct labor-hours:

$114,000 + ($1.00 * 12,000) = $126,000

Predetermined overhead rate = $126,000 / 12,000 = $10.50 per direct labor-hour

2) To find Mr. Wilkes' total job cost, we need to add up the costs of the direct materials and direct labor, and then apply the predetermined overhead rate to the direct labor hours used:

Direct materials cost: $626

Direct labor cost: $292

Total direct costs: $626 + $292 = $918

Overhead cost: $10.50 * 4 = $42

Total job cost: $918 + $42 = $960

3) To find the selling price, we need to add a markup of 40% of the total job cost:

Total job cost: $960

Markup: 40% * $960 = $384

Selling price: $960 + $384 = $1344
