factors of 45

Let us learn about factors of 45

45 numbers is a composite number; 45 has factors other than one & itself. 45 is not a prime number.

The 6 factors of 45 are 1, 3, 5, 9, 15, & 45.

The factor pairs of 45 are 1 x 45, 3 x 15, & 5 x 9.

The proper factors of 45 are 1, 3, 5, 9, & 15 or if the definition you are using excludes 1, they are 3, 5, 9, & 15.

The prime factors of 45 are 3, 3, & 5.

There is repetition of these factors, therefore if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.

The 2 distinct prime factors of 45 are 3 & 5.

The prime factorizations of 45 are 3 x 3 x 5 or, in index form 3² x 5.

There cannot be common factors, a least common multiple of a single number or a greatest common factor because "common" refers to factors or multiples that 2 or more numbers have in common.

log identities

Let us learn about log identities

An integer base or number base is the power or exponent to which the base must be raised in order to provide that number is said to be as natural log identities. Real-valued function of a real variable also applied the natural log identities. Inverse function of the exponential function is applying natural logarithm function.
The log identities are written as:
log_ex or ln x
Where e = 2.71828182846.
The Best Example of log identities
In that case we need to apply the addition law of natural logarithms,
Such as, log_eA + log_eB = log_e (A x B).
1. Solve the log identities problem using natural log identities, given ln(4 x 4) =?
Given problem is here to, ln (4x4)
Log identities for the given problem is, ln (x * y) = (ln x) + (ln y).
ln (4 x 4) = ln4 + ln4
Plug the ln2 and ln4 values in the log identities, = 1.386 + 1.386
Then add the values,
= 1.386 + 1.386 = 2.772 = (2 x 4) = 2.772.

substitution method calculator

Let us learn about substitution method calculator

-->
Substitution method calculator used to solve an algebraic expression where we replace 1 variable by an equivalent in terms of another variable. Substitution method calculator works to get the equation & solve for the variable & substitutes the values.
Solve by using substitution method calculator.
8x + 9y = 4, - 9x + y = 20.
Solution:
8x + 9y = 4 ---- (1)
- 9x + y = 20 ---- (2)
From equation (2), we get
- 9x + y = 20
y = 20 + 9x so plug this y = 20 + 9x in equation 1 & solve for x

8x + 9 (20+ 9x) = 4
8x + 180 + 81x = 4

89x + 180 = 4

89x = - 176

x = - 1.97 Plug this x value in equation 2 to find out y value.

- 9 (- 1.97) + y = 20

17.79 + y = 20

y = 2.21
Answer is x = - 1.97, y = 2.21.

line plot example

Let us learn about a line plot,& line plot example

A line plot helps us to find data on a number line with x or other marks to show frequency

1 type of graph is a line plot. A line plot provides an easy method to organize data. They are usually applied when there is 1 group of data, & fewer than 50 values.

A line plot includes of a horizontal number line, on which each value of a set is denoted by an x over the corresponding value on the number line. The number of x's above each score indicates that how many times each score occurred.

5 grade math

Let us learn about 5 grade math & fifth grade students
5th graders receive their 1st basic geometry problems & by the end of the school year they should be able to identify & categorize triangles by their properties & measure & construct triangles & angles with a protractor. They will also learn about tessellations, planes, & grid coordinate systems.
Before advancing to the 6th grade, students will design surveys & try to collect data & adequately record it using graphs & diagrams. The 5th grade also prepares learners to make appropriate predictions when presented with sufficient background information on a given situation.
Many 5th grade math students are able to earn a passing grade in their math classes without fully understanding the concepts which they have been taught. It's critical for parents to monitor their kid's progress. Some math learners can slip by without showing major signs of confusion. This means that even if your kid does not ask for help with their 5th grade math they could still have skill gaps. These skill gaps will interfere with success in 6th grade math.
Math assessment tests are 1 method for parents to learn how much their kid truly gained from grade 5. These assessments test are available online through Internet tutoring centers. Additional information on this math subject can be found in the math section of online math tutoring website.

average deviation

Let us learn about average deviation

The average deviation is an estimation of how far off the actual values are from the average value, assuming that your measuring tool is accurate. You can apply this as the estimated error. Sometimes it is given as a number or as a percentage.

The average absolute deviation or the average deviation is a measure of dispersion. It is the average of absolute deviations of the exclusive values (individual values) from the mean or from the median. The average deviation is 1 of several indices of variability which statisticians apply to characterize the dispersion in-between the measures in a given population. Average deviation= divided by number of deviations involved & deviation values added together Then, place a -+ along with that number to the right of the average value.

Average Deviation is the accurate method of finding the error margin from Standard deviation we will use the average deviation. It is easy to multiply 0r to Calculate. The Average deviation is known as average absolute deviation.
The individual values from the median or from the mean’s averages are known as the Average absolute deviation. Average Deviation is a measure of dispersion. Average deviation is known as the Mean deviation. Average Deviation is applied to characterize the dispersion among the measures from given data & Average Deviation is the one of the several indices of the variability.

equivalent fractions worksheets

Let us learn about equivalent fractions worksheets

Printable math equivalent fractions worksheets, a valuable tutor or parent lesson plan resource of printable, copyable, worksheets featuring fraction activities for learners consolidation.

An ideal tutor resource for lesson plans, home educators or parents looking to give there kids more practice at fraction calculations by using equivalent fractions calculator. Each question sheet has a matching solutions sheet, & there is a help page to show us how to work out the problems.

A fraction is a number which is the portion or part of a whole. Key to learn fractions understand how to represent part of the whole. Sometimes the whole will be a pizza, a measuring cup & it is important to understand what the part is each time the whole is different.

When starting with fractions we begin by focusing on 1/2 and the 1/4 before entering into equivalent fractions worksheets & using the 4 operations with fractions (adding, subtracting, multiplying and dividing).
