A home business has an average income of $900.00 per month with a standard deviation of $15.00. If the income in a given month i s $930.00, what z-score corresponds to this value?
1 answer:
Answer = 2.00 Z score is a statistical that corresponds to the standardization of the regular score to a normal distribution The formula for Z score is Z = [X - mean ]./ (standard deviation) Here X = 930.00; mean = 900.00; and standard deviation = 15.00 Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00 Therefore, your answer is 2.00 Hope I helped :)

(7^x)^4 is equal to 7^(4x). 7^2 * 7^3 is equal to 7^(2+3) which is equal to 7^5. 7^5 / 7^(3x) is equal to 7^(5 - 3x). you wind up with 7^(4x) is equal to 7^(5 - 3x) this is true if and only if 4x = 5 - 3x.

A factor is a number that leaves no remainder behind after it divides the specific number. On the contrary, multiple is a number reached by multiplying a given number by another.
