Base 3 logarithm of 81 equals 4 .The logarithmic form, written as log of "b" to base "a" is equal to "n," .

How many times must one "base" number be multiplied by itself in order to get another specific number is the subject of the mathematical expression known as a logarithm (or log). Mathematics includes both logarithms and logs. They share a connection with exponential functions. Logarithms are the opposite of exponentiation because they reveal the exponent (or power) required to create a given number. They were helpful in the past for splitting or multiplying huge numbers.

Answer:

1) 3/2

2) 13/10

3) 1/3

4) 9/7

5) 13/20

Step-by-step explanation:

By mathematical induction, we have proven that for any positive integer n, an = −2n − 4 + 6 * 2n.

Base case:

For n=1, we have a1 = 6, which satisfies the formula for a1: a1 = −2(1) − 4 + 6*2(1) = 6.

Inductive hypothesis:

Assume that the formula holds for some arbitrary positive integer k, i.e. ak = −2k − 4 + 6 * 2k.

Inductive step:

We need to show that the formula also holds for k+1, i.e. a(k+1) = −2(k+1) − 4 + 6 * 2(k+1).

Using the formula for ak in the definition of the sequence, we have:

a(k+1) = 2ak + 2(k+1)

= 2(-2k - 4 + 6 * 2k) + 2(k+1)

= -4k - 8 + 12*2k + 2k + 2

= -2k - 6 + 6 * 2(k+1)

Simplifying, we get:

a(k+1) = −2(k+1) − 4 + 6 * 2(k+1)

This is exactly the formula we wanted to prove for a(k+1).

Therefore, by mathematical induction, we have proven that for any positive integer n, an = −2n − 4 + 6 * 2n.

Step-by-step explanation:

compare it with the equation of the circle

In mathematics, "\(a^2\)" denotes the square of a number or variable "a." It is calculated by multiplying "a" by itself.

4For example, if "a" is 5, then a^2 would be 5*5, which equals 25. When "a" represents a positive number, its square is always positive.

If "a" is negative, its square is still positive since a negative multiplied by a negative results in a positive.

In geometrical terms, if "a" represents the length of the side of a square, then a^2 represents the area of that square. This notation is part of the general concept of exponentiation.

The standard error of the sample mean is 1.21.

Given;

Suppose a diet regimen for men results in an average weight loss of between 13. 4 and 18. 3 pounds, according to a 95% confidence interval. These findings were based on a group of 42 men who were classified as overweight at the beginning of the four-month trial.

A 95% confidence interval for a population mean is (13.4, 18.3)

Upper limit = 18.3

Lower limit = 13.4

Since population SD is unknown, this interval is constructed using the t distribution.

n = 42

c = 0.95

∴ α = 1 - c = 1 - 0.95 = 0.05

α/2 = 0.025

Also, d.f = n - 1 = 42 - 1 = 41

∴ ta/2.d.f =  ta/2.n-1  =  t0.025,41  =  2.02 . . . . use t table

Now,

The margin of error = (Upper limit - Lower limit)/2

                                 = (18.3 - 13.4)/2

                                 = 2.45

But,

Margin of error = ta/2.d.f-  * (s / \sqrt{} n)

When a fair coin is tossed five times, there is a 5/16 chance of getting two exact heads.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty. A probability is a numerical representation of the possibility or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Therefore, the compound interest of the annuity due of BD 400 paid each 4 months for 6.2 years at a nominal rate of 3% per annum is BD 40,652.17.

Compound interest of an annuity due can be calculated using the formula:A = R * [(1 + i)ⁿ - 1] / i * (1 + i)

whereA = future value of the annuity dueR = regular paymenti = interest raten = number of payments First, we need to calculate the effective rate of interest per period since the nominal rate is given per annum. The effective rate of interest per period is calculated as

:(1 + i/n)^n - 1 = 3/1003/100 = (1 + i/4)^4 - 1

(1 + i/4)^4 = 1.0075i/4 = (1.0075)^(1/4) - 1i = 0.0303So,

the effective rate of interest per 4 months is 3.03%.Next, we can substitute the given values in the formula:

A = BD 400 * [(1 + 0.0303)^(6.2 * 3) - 1] / 0.0303 * (1 + 0.0303)A = BD 400 * [4.227 - 1] / 0.0303 * 1.0303A = BD 400 * 101.63A = BD 40,652.17

The sum of the cubes of the two numbers is -1.

Let's consider two numbers, denoted as x and y. If their sum is 1, we can express it as the equation x + y = 1. Similarly, if their product is 1, it can be represented as xy = 1.

To find the sum of their cubes, x³ + y³, we can use the identity (a³ + b³ = (a + b)(a² - ab + b²)). Applying this identity, we have:

x³ + y³ = (x + y)(x² - xy + y²)

Now, let's substitute the known values from the given equations:

x³ + y³ = (x + y)(x² - xy + y²)

        = (1)(x² - (1)(y) + y²)

        = x² - y + y²

Next, we express x² and y² in terms of x and y:

x² = (x + y)² - 2xy

y² = (x + y)² - 2xy

Substituting these expressions into x³ + y³ = x² - y + y², we get:

x³ + y³ = (x + y)² - 2xy - y + (x + y)² - 2xy

Considering the known values x + y = 1 and xy = 1:

x³ + y³ = (1)² - 2(1) - 1 + (1)² - 2(1)

        = 1 - 2 - 1 + 1 - 2

        = -1

Therefore, the sum of the cubes of the two numbers is -1.

Confidence Interval = 0.1703 ± 0.0222 Confidence Interval ≈ (0.1481, 0.1925)  We are 95% confident that the true proportion of student loan borrowers with loans totaling more than $40,000 for their undergraduate education falls between approximately 0.1481 and 0.1925.

To construct a confidence interval to estimate the population proportion, we can use the following formula:

Confidence Interval = Sample Proportion ± Margin of Error

First, let's calculate the sample proportion:

Sample Proportion = Number of borrowers with loans > $40,000 / Total number of borrowers

Sample Proportion = 218 / 1280 ≈ 0.1703

Next, we need to determine the margin of error. For a 95% confidence level, we can use the formula:

Margin of Error = Z * sqrt((Sample Proportion * (1 - Sample Proportion)) / n)

Where Z is the z-value corresponding to the desired confidence level (in this case, 95%), and n is the sample size.

For a 95% confidence level, the critical z-value is approximately 1.96.

Margin of Error = 1.96 * sqrt((0.1703 * (1 - 0.1703)) / 1280)

Margin of Error ≈ 0.0222

Now, we can construct the confidence interval:

Confidence Interval = 0.1703 ± 0.0222

Confidence Interval ≈ (0.1481, 0.1925)

We are 95% confident that the true proportion of student loan borrowers with loans totaling more than $40,000 for their undergraduate education falls between approximately 0.1481 and 0.1925.
