Join our site today to ask your question. x = 10-3.93 = 1.2 x 10-4 Finding the nth root. If the standard deviation of a given data set is equal to zero, what can we say about the data values included in the given data set? so let us flip sides (and the inequality sign!): x > 7 Do you see how the inequality sign still "points at" the smaller value (7) ?

Mathematics CyberBoard. Left Side: Right Side: Check the solution x = -2 by substituting -2 in the original equation for x. Enter in the number for which you want the nth root. 2.2 x 10-20 Press the button for finding the nth root followed by the exponent, n, and the "=" or If you want to preserve the original nesting, this is what the Flattening option does: ToValues[sols, Flattening -> None] // InputForm {{1}, {2}, {3}} We can specify a function to be https://forums.techguy.org/threads/solved-question-about-setting-a-value-for-x.593391/

Assume the change in the concentration of the product is 0. Try always to clearly define and label your variables. Make an ICE chart to determine change and equilibrium quantities starting with those resulting from the 100% conversion.

Top Assuming That the Change is Small There are two special cases where we can solve an equation by assuming the variable is small. sols[[2]] If you really want to assign values to x and y globally, you could use: Set @@@ sols[[1]] but you must clear x and y before using another set: Clear[x, You can also check your answer by graphing (the left side of the original equation minus the right side of the original equation). Wolfram Alpha In this case we want to return lists in the form {variable name, variable value}: F[var_][value_] := {var, value} ToValues[sols, F, IndexedFunction -> True] // InputForm {{x, 1}, {y, 2}, {z,

SAT Mean, Median, and Mode Math Question This video will show you how to answer SAT mean, median, and mode math questions.

If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer. Khan Academy See e.g. Which of the following must be true? How do we solve something with two inequalities at once?

Equation Solver b) What are the new values of the mean and the standard deviation if each data value of the set is multiplied by the same constant k?Explain. Mathway I see in other parts of the code so far I have encountered g (dot)drawString.

Solution: Arrange the numbers in ascending order with x in the middle. 3, 4, x, 7, 8 This tells us that the possible values of x are 4, 5, 6 and Let us try an example: Solve: -2y < -8 Let us divide both sides by -2 ... share|improve this answer edited Jul 12 '16 at 18:24 answered May 14 '15 at 12:59 Peltio 3,81131723 add a comment| Your Answer draft saved draft discarded Sign up or log The median of the list is 6, and the number 3 occurs most often in the list. Algebra Calculator

Which gives x = y = z = w = μ : all data values in the set with σ = 0 are equal. height (in cm) - classes midpoint frequency 120 <- 130 125 2 130 <- 140 135 5 140 <- 150 145 25 150 <- 160 155 10 160 <- 170 165 Substitute into the equation and solve for "x." Check to see if the change is within the limits set by your instructor. (Here we use 5%.) The change in the HI What happens to the resistance of a wire if it is heated up?

I can't remember to do somethings if I don't know why they are done. The frequency table of the monthly slaries of 20 people is shown below. Simplify equation and solve for the change.

salary(in $) frequency 3500 5 4000 8 4200 5 4300 2 a) Calculate the mean of the salaries of the 20 people.

Make an ICE chart. This site is completely free -- paid for by advertisers and donations. By re-checking the original exercise, I was able to provide an appropriate response, being the lengths of the two pieces, including the correct units ("meters"). << Previous Top| 1 | 2 Show Step-by-step Solutions SAT: Mean, Median, Mode In the SAT, mean, median and mode questions may be given in the following manner.

Are you looking for the solution to your computer problem? b) Calculate the standard deviation of the salaries of the 20 people. This method will work with most polynomials. Check the solution x=3 by substituting 3 in the original equation for x.

The standard deviation does not change. I. Can you identify this receptacle?
