Suppose that a random variable Z has a standard normal distribution. Use a standard normal table such as this one to determine the probability that Z is between –1.67 and 1.33. Give your answer in decimal form, precise to at least three decimal places. P(-1.67 < Z < 1.33) = w​

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.

Two times a number plus three times another number equals 4. three times the first number plus four times the other number is 7. find the numbers
