Randomly selected students participated in an experiment to test their ability to determine when one minute (or sixty seconds) has passed. forty students yielded a sample mean of 58.8 seconds. assuming that sigmaequals11.3 seconds, construct and interpret a 99% confidence interval estimate of the population mean of all students.

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.

Solve the equation below: (x+4)/6x=1/x a. x=2 b. x=0,2 c. x=-2 d. x=0,-2

Someone me! if you’re smart you can solve this!
