Answer:
[tex]\frac{8}{b^{30} }[/tex]
Step-by-step explanation:
Start within the parentheses
1. Divide coefficients
6/3 = 2
2. Divide variables
When dividing exponents with the same base, in this case b, you subtract.
b^20 - b^30 = b^-10
3. Exponent outside parentheses
When there's an exponent on an exponent, you multiply the exponents.
(2b^-10)^3
8 b^-30
4. Simplify?
This step isn't necessary, but when you have a negative exponent on a variable, the variable can be put in the denominator with a positive exponent.
8b^-30 can become 8/b^30

the living standard in country x doubles in 12 years. what is its average annual growth rate roughly?
Answers
A country will roughly double its gdp in twelve years if its annual growth rate is 5.8 using the rule of 70.
The rule of 70 is used to determine the time it takes a country to double it growth rate.
To double in 12 years =70/12 = 5.8
Therefore, A country will roughly double its gdp in twenty years if its annual growth rate is 5.8 using the rule of 70.
A measure of the rise in the value of an investment or revenue stream over the course of a year is the annual growth rate, often known as the "simple growth rate" or "average annual growth rate (AAGR)".
The formula for calculating annual growth rate divides the total value of annual growth at the beginning of the year by the total value of that growth at the end of the year.

what information is missing for the interpretation of an anova if you only run an omnibus/overall anova (without any post-hoc tests)? why do we need to run follow up tests when we conduct a one-way anova?
Answers
The statistical method known as analysis of variance (ANOVA) is used to examine how different means differ from one another.
When you only run an omnibus/overall anova without any post-hoc tests, you will be unable to determine which of the groups are statistically different from each other. This is because an omnibus/overall anova simply tells you whether there is a significant difference between any of the groups, but does not tell you which groups are different. Follow up tests are needed to determine which of the groups are statistically different from each other.

A group of friends wants to go to the amusement park. They have no more than $190 to spend on parking and admission. Parking is $7, and tickets cost $15. 25 per person, including tax. Write and solve an inequality which can be used to determine pp, the number of people who can go to the amusement park.
Answers
With $190, a maximum of 12 people can visit the theme park, where admission costs $15.25 per person and parking costs $7.
What is inequality?In mathematics, "inequality" refers to a connection between two expressions or values that are not equal to one another. The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in lieu of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. Finding the x values for which the inequality holds true is what we are most interested in.
Here,
The total amount they can spend=$190
Cost of parking=$7
Cost of ticket per person=$15.25
Let the number of person be x,
15.25x+7≤190
15.25x≤183
x≤12
There can be at most 12 person that can go to the amusement park with $190 where cost of tickets is $15.25 per person and cost of parking is $7.

Find the equation of the line that passes through the point (-4, 11) and is perpendicular to the following line.
y= -2/3x -7
Answers
The equation of a line perpendicular to y = (-2/3)x - 7 is y = (3/2)x + 17.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know lines perpendicular to each other have slopes that are negative reciprocals of each other.
So, the slope of the perpendicular line to the given line y = (-2/3)x - 7 is (3/2)
which passes through the point (-4, 11) is,
11 = (3/2)(-4) + b.
b = 11 + 6.

Inequality (C) -3.2 + 1.5n ≤ 8.6 correctly represents the sentence "the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6."
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.
Both mathematical phrases, equations, and inequalities are created by connecting two expressions.
The equal sign (=) indicates that two expressions in an equation are believed to be equivalent.
The symbols >, <, ≤ or ≥ indicate that the two expressions in inequality are not always equal.
So, the sentence we have is:
the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6
Which can be written in inequality as:
-3.2 + 1.5n ≤ 8.6

Answers
Brace's taxable income is $50,000.
It is given to us that -
Brace Inc. owns 90% of West common stock
Brace generated $50,000 operating income
and, Brace received $10,000 dividends from West
We have to find out Brace's taxable income.
Taxable income can be defined as the income (income amount) of an individual or business that federal or state government agencies use as the basis for determining the taxes owed on them.
The correct formula representing taxable income can be stated as -
A. Taxable income = Total income - Exclusions - Adjustments to income - Deductions - Exemptions.
B. Taxable income = Gross income - Adjustments to income - Deductions - Exemptions.
C. Taxable income = Adjusted gross income - (Deductions + Exemptions).
Since, it is mentioned that Brace Inc. owns 90% of West common stock, it can be determined that the stock share is more than 80%.
This implies that there will be 100% deduction in the value of taxable income since the stock share is more than 80%.
Thus, Brace's taxable income is $50,000.
