Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean j = 155 days and standard deviation o = 13 days.
Complete parts (a) through ( below.
(a) What is the probability that a randomly selected pregnancy lasts less than 151 days?
The probability that a randomly selected pregnancy lasts less than 151 days is approximately
(Round to four decimal places as needed.)

Consider the functions below. function 1 function 2 function 3 select the statement which is true about the functions over the interval [1, 2] a b function 3 has the highest average rate of change function 2 and function 3 have the same average rate of change. function and function 3 have the same average rate of change function 2 has the lowest average rate of change d.

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.

Icould really use some with this question.
