numbers, decimal point markers (period or comma), sign indicators (-),spaces (e.g., as thousands separator, 5 000), “E” or“e” (used in scientific notation). NOTE: For scientificnotation, a period MUST be used as the decimal point marker.Complex numbers should be in the form (a + bi) where “a” and“b” need to have explicitly stated values.For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas{9i} is not. Suppose that the average weekly earnings for employees in general automotiverepair shops is $450, and that the standard deviation for the weeklyearnings for such employees is $50. A sample of 100 such employees isselected at random. Find the mean of the samplingdistribution of the means of average weekly earnings for samples ofsize 100. Place your answer in the blank. Do not include a dollar sign. Forexample, 123 would be a legitimate entry.
Trigonometric Identities
Trigonometry in mathematics deals with the right-angled triangle’s angles and sides. By trigonometric identities, we mean the identities we use whenever we need to express the various trigonometric functions in terms of an equation.
Inverse Trigonometric Functions
Inverse trigonometric functions are the inverse of normal trigonometric functions. Alternatively denoted as cyclometric or arcus functions, these inverse trigonometric functions exist to counter the basic trigonometric functions, such as sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (cosec). When trigonometric ratios are calculated, the angular values can be calculated with the help of the inverse trigonometric functions.

For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas
{9i} is not.
