Find the sign of the largest absolute value. -5 has a negative sign.

A 1 in a z-score means 1 standard deviation, not 1 unit. So if the standard deviation of the data set is 1.69, a z-score of 1 would mean that the data point is 1.69 units above the mean. In Sal's example, the z-score of the data point is -0.59, meaning the point is approximately 0.59 standard deviations, or 1 unit, below the mean, which we can ...Dilation. Dilation is a process of changing the size of an object or shape by decreasing or increasing its dimensions by some scaling factors. For example, a circle with radius 10 unit is reduced to a circle of radius 5 unit. The application of this method is used in photography, arts and crafts, to create logos, etc.A set is a collection of things, usually numbers. We can list each element (or "member") of a set inside curly brackets like this: Common Symbols Used in Set Theory Symbols save time and space when writing.

Writing means that the elements of the set A are the numbers 1, 2, 3 and 4. Sets of elements of A, for example , are subsets of A . Sets can themselves be elements. For example, consider the set . The elements of B are not 1, 2, 3, and 4. Rather, there are only three elements of B, namely the numbers 1 and 2, and the set .

z= x+iy: The modulus of zis jzj= r= p x2 +y2: The argument of zis argz= = arctan y x :-Re 6 Im y uz= x+iy x 3 r Note: When calculating you must take account of the quadrant in which zlies - if in doubt draw an Argand diagram. The principle value of the argument is denoted by Argz, and is the unique value of argzsuch thatIn a wide sense, as argued below, the answer is no. Indeed, R(z) ℜ ( z) is not a holomorphic function since its image is the real line. In this sense, there is no formula for R(z) ℜ ( z) that does not involve z¯ z ¯, because the Cauchy–Riemann equations fail for R(z) ℜ ( z) : This was said already in the comments.

Meaning of Mode in Maths. The mode or modal is the value that appears most frequently in a set.

A ring is a set R equipped with two binary operations + (addition) and ⋅ (multiplication) satisfying the following three sets of axioms, called the ring axioms.

(ii). If we specify the branch as − π < arg(z) ≤ π then we have the following arguments: arg(1) = 0; arg(i) = π / 2; arg( − 1) = π; arg( − i) = − π / 2.Matrix dimensions. The dimensions of a matrix tells its size: the number of rows and columns of the matrix, in that order. Since matrix A has two rows and three columns , we write its dimensions as 2 × 3 , pronounced "two by three". In contrast, matrix B has three rows and two columns , so it is a 3 × 2 matrix. B = [ − 8 − 4 23 12 18 10]In mathematics, a variable (from Latin variabilis, "changeable") is a symbol that represents a mathematical object.A variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set..

We can use the following steps to calculate the z-score: The mean is μ = 80. The standard deviation is σ = 4. The individual value we're interested in is X = 75. Thus, z = (X - μ) / σ = (75 - 80) /4 = -1.25. This tells us that an exam score of 75 lies 1.25 standard deviations below the mean.

The z test can be performed on one sample, two samples, or on proportions for hypothesis testing. It checks if the means of two large samples are different or not when the population variance is known. A z test can further be classified into left-tailed, right-tailed, and two-tailed hypothesis tests depending upon the parameters of the data.
