Expression as a single natural logarithm is 1.38629436112

ln 24- ln 6

ln(24/6)

ln 4 = 1.38629436112

The inverse of an exponential function, the natural log is the logarithm to the base of the number e. Natural logarithms are unique varieties of logarithms that are employed in the treatment of time and growth-related issues.

The distinction between log and ln is that log is expressed in terms of base 10, while ln is expressed in terms of base e. As an illustration, log of base 2 is denoted by log2 and log of base e by loge = ln (natural log).

Rebeeca’s histogram most likely shape will be Skewed to the left.

The histogram shows a symmetrical data distribution. A distribution is symmetrical if a vertical line can be drawn at any point in the histogram such that the shapes to the left and right of the vertical line are mirror copies of each other.

The mean and the median both reflect the skewing, but the mean reflects it more so. This is because the mean and median are measures of central tendency. Because in Rebecca’s data the mean is smaller compared to the median, it makes the histogram skewed to the left. If the median were to be smaller than the mean, it would be skewed to the right.

Having 7 tiles named A to G in a bag and picking 3 of them have the probability that they'll spell BAG is 0.0050.

Probability is the chance of occurring a certain event out of the total possible events that can occur in a given scenario.

According to the given question you put 7 tiles with the letters A through G into a bag.

Total no. of sample space N(S) = 7.

∴ The probability of getting getting B named tile P(B) is = 1/7.

Now as we are not replacing the tiles there are 6 tiles now so probability of getting A named tile P(A) = 1/6 and in the same way probability of getting G named tile is P(G) = 1/5.

∴ The probability that they will spell BAG P(BAG) is = (1/7)×(1/6)×(1/5)                      = 0.0050.

Step-by-step explanation:

The inverse for the function f (x) = ∛x / 3 will be f ⁻¹ (x) = 3 x³.

We are given the function:

f (x) = ∛x / 3

we need to find the inverse of the function.

First we will write the function in the form of x.

y = ∛x / 3

y³ =  x / 3

3 y³ =  x

x = 3 y³

So, the inverse function will be:

f ⁻¹ (x) = 3 x³

Therefore, the inverse for the function f (x) = ∛x / 3 will be f ⁻¹ (x) = 3 x³.

Step-by-step explanation:

The equation of the circle with center at (-1, 5) and passes through the point (2, 9) is equal to (x + 1)² + (y - 5)² = 25.

Mathematically, the standard form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

Next, we would determine the length of the radius (r) by using the distance formula. Mathematically, the distance between two (2) points that are on a coordinate plane can be calculated by using this formula:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Substituting the given parameters into the formula, we have;

Radius = √[(2 - (-1))² + (9 - 5)²]

Radius = √[(2 + 1)² + (4)²]

Radius = √[3² + 4²]

Radius = √[9 + 16]

Radius = √25

Radius = 5 units.

For the equation of a circle, we have:

(x - h)² + (y - k)² = r²

(x - (-1))² + (y - 5)² = 25

(x + 1)² + (y - 5)² = 25

Write the equation of the circle with center at (-1, 5) and passes through the point (2, 9).

Answer:

b > 5/6 or b < 11/6

Step-by-step explanation:

1.  Divide both sides by -4
[tex]\dfrac{-4(|6b-8|)}{-4} < \dfrac{12}{-4}[/tex]

2. Simplify above
[tex]|6b-8| > -3[/tex]

3. The absolute value of an expression means that the expression can be positive or negative
Here |  | represents the absolute value of 6b-8

For an absolute value to satisfy the above inequality
either 6b - 8 > -3 or 6b - 8 < - (-3)

(This follows from the fact that if |x| > -a, x > -a
or x < -(-a) ) which is the same as x < a

First case: 6b - 8 > -3:

6b - 8 + 8  > -3 + 8     ( Add 8 to both sides)
==> 6b > 5
==> 6b/6 > 5/6                   (Divide both sides by 6)
==> b > 5/6  

Second case: 6b - 8 < 3
6b −8 + 8 <3 + 8                    (Add 8 to both sides)
==> 6b<11                                    

==> 6b/6 < 11/6    (Divide both sides by 6)

==> b < 11/6

The result of the expression -(3)⁰.⁵x for x = -2 is 3.4, for x = 0 is 0 and for x = 2 is - 3.4

The question states to evaluate the given expression, that is, -(3) ⁰.⁵ x for the given values of x, that are, x = -2, x = 0, and x = 2.

This question can be easily solved by using the concept of substitution. We have to substitute the given values of x in the given expression one after the other and note the answer.

For x = -2.

we get, -(3) ⁰.⁵ ( - 2) = - 1.7 * (-2) = 3.4

For x = 0.

we get, -(3) ⁰.⁵ ( 0 ) = - 1.7 * ( 0 ) = 0

For x = 2.

we get, -(3) ⁰.⁵ ( 2 ) = - 1.7 * ( 2 ) = - 3.4

The multiplicative inverse of a number is  a number that when multiplied by the original number gives the product as 1. The multiplicative inverse of 'a' is denoted by a-1 or 1/a. In other words, when the product of two numbers is 1, they are said to be multiplicative inverses of each other. The multiplicative inverse of a number is defined as the division of 1 by that number. It is also called the reciprocal of the number. The multiplicative inverse formula says that the product of a number and its reciprocal is 1.

There are various types of numbers like natural numbers, fractions, unit fractions, negative numbers, etc. Let us understand the multiplicative inverse formula for each type of number.

Natural numbers are counting numbers starting from 1. The multiplicative inverse of a natural number a is 1/a.

Multiplicative Inverse of Integers

Finding the multiplicative inverse of positive integers is the same as natural numbers (explained above). Just like positive integers, the product of a negative number and its reciprocal must be equal to 1. Thus, the multiplicative inverse of any negative number is its reciprocal. For example, (-6) × (-1/6) = 1, therefore, the multiplicative inverse of -6 is -1/6. Note that the multiplicative inverse of a negative number is always negative. And, in the multiplicative inverse of a negative integer, the negative sign will attach to the numerator, and not with the denominator.

How to Find Multiplicative Inverse of a number :

The multiplicative inverse of a number is also known as its reciprocal. It is very easy to find the multiplicative inverse of a number using the following steps:

Step 1: Divide the given number by 1.

Step 2: Write it in the form of a fraction. Say, the reciprocal of a is 1/a.

Step 3: Simplify and get the answer.

Let us find the multiplicative inverse of 2/3. The first step is to divide it by 1, which will result in 1/(2/3) = 3/2. Therefore, the reciprocal of 2/3 is 3/2.
