5x^-6y^-2/y

Answers

Answer 1
Answer: (5x^(-6)y^(-2))/(y) = (5(-1)^(-6)3^(-2))/(3) = (5(1)(1)/(9))/(3) =((5)/(9))/( 3)\n\n= (5)/(9) / 3 = (5)/(9) * (1)/(3) = \boxed{\bf{(5)/(27)}}

Your answer is 5/27.

A store manager did a study to determine the amount of money the first 50 customers spent in her store. The data are approximately normally distributedwith a mean of $29.60 and a standard deviation of $10.50. The formula for normalizing data is: Z= (X−μ / σ) Z is the normal score X is a discrete data value μ is the mean σ is the standard deviation Determine the probability that a customer spent over $35. Enter your answer as a decimal to the hundredths place.

Answers

Simply input the data given, using the mentioned formula.
X=$35.00
μ=$29.60
σ=$10.50

Z= (X−μ / σ)
^^ This formula is actually wrong though... the correct way to write it is:

Z= (X−μ) / σ
Z=(35.00-29.60)/10.50
Z=5.4/10.50
Z=0.51
