Dale is riding on a bike course that is miles long. So far, he has ridden miles of the course. What percentage of the course has Dale ridden so far?

Answer:

274878070200

Step-by-step explanation:

4 to the power 11 = 4194304

4 to the power -8 = 0.00001525878

4194304/0.00001525878 = 274878070200

The correct answer is x = 2

(x + 1 < 4) ∩ (x-8>-7)

Make x the subject in each case:

(x<4-1)(x>-7+8)

        (x<3)∩(x>1)

If x<3, then x could be 2, 1, -1, etc.

If x>1, then x could be 2, 3, 4, etc.

Thus (x<3)∩(x>1) = 2

Answer:

x = 2

Step-by-step explanation:

Hello!

We are looking at the intersection of two sets, or common values found between two sets of data.

We can solve for x on each side and find any common values between.

As you can see, the intersection occurs at the common values. The only value that is common between the two sets is 2.

Therefore, the intersection of these sets is 2.

The derivative of f(x) is option A.

What is derivative?

The instantaneous pace at which one quantity changes in relation to another is referred to as a derivative in mathematics.

Main Body:

Since the derivative of \(e^{x}\) is just \(e^{x}\) , application of the chain rule to a composite function with \(e^{x}\) as the outside function means that:

         \(\frac{dy}{dx} (e^{f(x)} )= e^{f(x) }.f'(x)\)

Now the derivative of 1/x = \(\frac{-1}{x^{2} }\)

Hence derivative of f(x) = \(-e^{\frac{1}{x} } /x^{2}\).

Madison figures out the average and range of chloride readings from wells close to the ocean. Other than a query, she has carried out an operation. The answer id option (d).

The standard deviation is a measure of variance from the mean that takes spread, dispersion, and dispersion into account. The standard deviation displays a "typical" divergence from the mean. It is a well-liked measure of variability since it retains the primary units of measurement from the data set.  A minor variation occurs when the numbers are close to the mean, while a high variation occurs when they are far from the mean.

The standard deviation describes the degree to which the results deviate from the mean. The average deviation, which depends on all values, is the most often used metric for measuring dispersion. Consequently, the standard deviation's value can be altered even by a slight change in one value.

Answer: A=78

Step-by-step explanation: 936/12=78

936 eggs were produced last year by the sizable dairy farm. 78 dozen eggs are produced by this farm. The answer is option (A).

The study of symbols for math and the procedures for using them to solve equations and comprehend the relationships between variables is the subject of the branch of mathematics known as algebra. When representing quantities and their relationships using letters and symbols, algebra uses graphs, functions, and expression manipulation in addition to equation and inequalities solving.

Numerous branches of science, technology, economics, and other disciplines make considerable use of algebraic concepts and methods. It is a fundamental area of mathematics that is frequently studied as a pre-requisite for more difficult maths and science courses.

Algebraic concepts that are important to know include:

Addition, subtraction, multiplication, and division are operations using numbers and variables.

Using variables to solve equations and inequalities

Algebraic expressions manipulation and simplification

Knowing how to graph both linear and nonlinear functions

Utilising matrices and vectors

studying trigonometric, rational, and polynomial functions

We must divide the total number of eggs by 12 to determine the number of dozen eggs produced.

The total mass of 2 apples, 2 pears and 2 oranges is 820.0133 g.

Let p be the mass of one pear in grams,

let a be the mass of one apple in grams,

let o be the mass of one orange in grams.

From the first sentence, we know that:

7p + 5a + 3o = 2030 (equation 1)

From the second sentence, we know that:

1p + 2a = 300 (equation 2)

From the third sentence, we know that:

1a + 2o = 420 (equation 3)

We want to find the total mass of 2 apples, 2 pears, and 2 oranges, which is:

2p + 2a + 2o  

multiply equation 2 with 7

=7p + 14a = 2100

subtract this from equation 1, and we get

9a -3o = 70 (equation 4)

multiply equation 3 with 9 to get

9a + 18o = 3780

subtract this with equation 4 to get

21o = 3710

o =176.67

substitute in equation 4 to get a

a= 66.67

substitute in equation 2 to get p

p=166.67

thus required:

Total mass of 2 apples, 2 pears and 2 oranges is 2p + 2a +2o =  820.0133 g

Step-by-step explanation:

The fixed overhead production volume variance is $11,520. The fixed overhead production volume variance measures the difference between the actual fixed overhead incurred and the standard fixed overhead based on the standard production volume. It indicates the impact of producing a different volume of units than the standard volume on fixed overhead costs.

Standard production volume: 25,900 direct labor hours

Actual production volume: 23,900 direct labor hours

Actual fixed overhead: $139,520

Standard fixed overhead per unit: $10.00

To calculate the fixed overhead production volume variance, we need to determine the difference between the standard fixed overhead based on the standard production volume and the actual fixed overhead incurred for the actual production volume.

First, we calculate the standard fixed overhead based on the standard production volume:

Standard fixed overhead = Standard fixed overhead per unit * Standard production volume

                      = $10.00 * 12,800 units

                      = $128,000

Next, we calculate the fixed overhead production volume variance:

Fixed overhead production volume variance = Actual fixed overhead - Standard fixed overhead

                                        = $139,520 - $128,000

                                        = $11,520

The fixed overhead production volume variance is $11,520.

This variance indicates that producing 12,800 units with an actual production volume of 23,900 direct labor hours resulted in a higher fixed overhead cost than expected based on the standard production volume. It suggests that the deviation from the standard production volume had an impact on fixed overhead expenses.

The mean of the given data set is 98.70

To find the mean of the given data set, we need to sum up all the values and then divide the sum by the total number of values.

Sum of the values = 23.4 + 35.6 + 73.1 + 58.0 + 18 + 723.4 + 35.6 + 73.1 + 58.0 + 18.7 + 33.8 + 33.8 = 1184.5

Total number of values = 12

Mean = Sum of values / Total number of values = 1184.5 / 12 =98.708

To round the answer to the nearest hundredth, we look at the digit in the third decimal place, which is 3. Since this digit is less than 5, we round down the second decimal place, giving us the final answer of:

Rounding to the nearest hundredth, we get the mean as 98.708

Therefore, the mean of the given data set is 98.70
