I will assume that the gap between the X and the 4 is due to this website's inability to include +'s so I will use a +.
geometric mean of (x-3) and (x+4) is x
x^2=(x-3)(x+4)
x^2=x^2+x-12
0=x-12
x=12

One cubic yard.
Congruent ones. A cube of side x has a volume of x3. Any other cube, of volume x3 must have sides of length x and so the two cubes must be congruent.
21 square feet (7'x3') = 1.95 square meters.
Suppose the cube has edges of length x. Then the area of each face (side) is x2. There are six faces so the total surface area is 6x2. The volume of the cube is x3. So 6x2 = x3 DIviding both sides by x2 gives x = 6.
The math problem X3 times 64/334 equals 4/7. Getting this answer you will first have to find the value of X.
x3 can mean a lot of things, for example:In math is can mean: the variable x equals 3.In BMW sportcars: X3 is a model of car with a meaning often known only to the car company.On mechanical drawings: x3 can mean times 3
If a random variable X has mean value m, and standard deviation s, then Skewness = E{[(x - m)/s]3} which can be simplified to skewness = [E(X3) - 3ms2 - m3]/s3 and for discrete X, E(X3) = sum of x3*Prob(X = x) where the summation is over all possible values of x. While for continuous X, E(X3) = integral of x3*f(x) where the integral is over the domain of X.
If x2 and x3 are meant to represent x2 and x3, then x2 times x3 = x5 You find the product of exponent variables by adding the exponents.
It is a cubic polynomial in x and its value depends on the value of x.
X3-1x-1 is known as a math problem. All you have to do is work to find what the value of X is.
The value of the BMW X3 depends on your location, year, milage, and peripherals. But for a 2009 BMW X3 with 50,000 miles that is in good, not excellent, shape, and all the basic options is worth $26,360.
x3
If you have n observations for a variable X: x1, x2, x3, ... xn thenMean = (x1 + x2 + x3 + ... + xn)/nTo find the median, put the Xs in order and find the middle one. If n is odd then it is the value of the X in the (n+1)/2 position. If n is even, then it is half the sum of the Xs in the n+2 and n/2+1 positions.There is no formula for the mode. It is simply the value that is observed most often.
Choose the lowest of the exponents. The GCF of x3 and x5 is x3
A mathematical mean is the average of a group of numbers. To find it, you add all of the numbers you're being asked to find the mean for and then divide by the number of numbers you added. In other words, the average.* * * * *There are other means which are useful in other circumstances. The two common ones are the geometric mean and the harmonic mean.The geometric mean, for a group of n positive numbers is the nth root of the product of the numbers.So, G(4,6,9) = cuberoot(4*6*9) =cuberoot(216) = 6The geometric mean is useful with numbers that are used as multipliers, such as growth rates.The harmonic mean of n numbers x1, x2, x3 ,... xn is the number H such thatn/H = 1/x1 + 1/x2 + 1/x3 + ... + 1/xnThe harmonic mean is useful when the average of rates is desired. For example, if you travel k miles at x mph and another k miles at y mph, your average speed would be H(x,y).Mean is another name for 'average'. Here you add up the scores and divide this new number by how many scores there are.in notation this is (Sigma (xf-xi)) / x
x=4.
