Bias

Let's learn about bias statistics in today's post.

There are four different types of bias in statistics:

• Spectrum bias
• Omitted variable bias
• Systematic bias
• Cognitive bias

Next time i will help you with the concept of statistics formulas.

Also you can avail help from expert online tutors. Not just in statistics but from an algebra tutor as well.

definition of mathematics

Let us learn about definition of mathematics

Mathematics is a study of relationships using different numbers & the study of the relationships between numbers, shapes, & quantities. Mathematics uses signs, symbols, & proofs & includes arithmetic, calculus, algebra, geometry, & trigonometry.

Mathematics is referred as Mathematical operations & processes involved in the solution of a problem or study of some scientific field

Mathematics is a group of related sciences, including geometry, algebra, & calculus, concerned with the study of number, quantity, shape, & space & their interrelationships by using a specialized notation

Mathematics is a science or group of related sciences that deals with the logic of quantity & shape & arrangement

The mathematics is deductive study of shape, quantity, & dependence.

inequalities calculator

Let us learn how to use inequalities calculator

Add all numbers in left side from the in equality.

Then add all numbers in right side from the inequality.

Add the entire variable with coefficients on the left side from inequality.

Add the entire variable with coefficients on the right side from the inequality.

Subtract all number on left side from both sides of the inequality.

Add all number on the left side from both sides of the inequality

Subtract all variable with a coefficient on the right hand side of the inequality from both sides of the inequality

Add all variable with a coefficient on the right hand side of the inequality from both sides of the inequality.

Simplify by dividing on both sides or by multiplying on both side with reciprocal of inequality.

sin 30 degrees

Let us learn about sin 30 degrees

Value of 30 Degree

• The value of sin 30 degrees = ½
• The value of cos 30 degrees =√3/2
• The value of tan 30 degree = 1/√3

zero degree angle is known as an acute angle, because the angle of 2 rays Is less than 90 degree & greater than 0 degree.

sin(135) = sqrt(2)/2
cos(135) = -sqrt(2)/2
sin(30) = 1/2
cos(30) = sqrt(3)/2

Note 135 deg is just the 45 deg angle in the upper left quadrant of the unit circle, where sines are postiive & cosines are negative

sin(135-30) = sin135cos30 - cos135sin30
................... = [sqrt(2)/2][sqrt(3)/2] - [-sqrt(2)/2][1/2]
.................. = sqrt(6)/4 + sqrt(2)/4
.................. = [sqrt(6) + sqrt(2)]/4
................... = 0.9659

sin(135) - cos(30) = sqrt(2)/2 - sqrt(3)/2
................................= [sqrt(2) - sqrt(3)]/2
................................= -0.1589

factoring calculator online

Let us solve problem using factoring calculator online

Factor the given expression, 2x² + 4x
Solution:
= 2x² + 4x
Taking the common terms outside,
= 2x(x + 2)
The solution is 2x (x+2).
Solve 6x² + 18x - 24 = 0 for x.
Solution
Given equation is 6x²+18x-24=0 for x.
Solve the given equation we get
. (6x - 24)(x + 1)=0
Here by equating the values to zero
6x-24=0, x+1=0
Here keep constant terms on 1 side & move the variables to other side.
6x=24, x=-1
The final solution is X=3/2, x = -1.

college level books

Let us learn about college level books

college level books are very important, helps Student to build our spirit, give information, help to pass time, make us more deep an cultural, helps us to write & think better, help us to chose people, because with college level books student will able to chose the persons that like the same books that student like... Since millions of centuries mankind write it's the way to preserve history, facts that without them all mankind was lost without identity... finally, open our mind to the world & makes us better persons.

College level books are real, true friend. Books provide lot of experience to us. They improve our knowledge. It helps us to collect countless information. It is true that books are our best friend the only thing they cannot talk them but we can read them. Student should always carry college level books while traveling. College level books help a lot to maintain a good vocabulary. Above all these college level books help solve the mystery of life sometimes, so they act as a true companion. Whenever student feels disturbed they should read college level books. College level books are the identity of college level students, a college student is known by the books he/she reads. No books are boring depends on interest of the college grade students declare them as boring or interesting.

College level books give peace to Student mind, increase attention & concentration, increases vocabulary, presence of mind, creativity & above all, college level books gives us knowledge which is considered to be the world's greatest treasure.

college level books make us feel heavenly.

midpoint formula calculator

Let us learn about midpoint formula calculator

The midpoint formula calculator is very handy while calculating the midpoint between any 2 points & is very commonly used in geometry both practically & during learning. In math, midpoint formula questions are very common & Learner should be well aware of how to use the midpoint formula calculator. The formula to find midpoint using calculator is actually quite logical, if you try to look at it closely, you will find that it is derived from the average of the x coordinates & y coordinates

The midpoint formula calculator is used when you need the point that is exactly between 2 other points. The midpoint formula is used when you need to find a line which bisects a specific line segment. Essentially, the 'middle point' known as the "midpoint"
