Suppose four cellphones are tested. Let D represent the defective cellphone and N for non defective cellphone. How many possible outcomes will occur from the experiment
Evaluate limits involving the expressions (sin t/t), (1 - cos t)/t) and ((e ^ t- 1)/t) and indeterminate forms type "0/0"
Directions: Create example of limits of functions and evaluate their limits.
1.(sint)/t
2.(1 - cos t)/t
3.(e ^ t - 1)/t
1.(sint)/t
2.(1 - cos t)/t
3.(e ^ t - 1)/t
Evalute limits involving the by constructjng their respective table of values
1.lim t -> 0 t/(sin t)
2.lim t -> 0 (sin t)/(2t)•(1 - cot t)/t
3.lim t -> 0 (e ^ t - 1/t)

The score of entrance examination takers who took a 600 item exam resemble a normal distribution with a mean of 220 and a standard deviations of 10. The coordinator would like to get the lowest 15% of thr scores and invite them for a retake examination. What range of scores indicates the inclusion in the retake of the exam?
A molding machine prepares a certain kind of car spare part with a target
diameter p = 42.23 mm. The machine has some variability, so the standard
deviation of the diameter is o = 0.003 mm. A sample of 10 spare parts is
inspected each hour for the process control purposes and record are kept of
the sample mean diameter. What will be the mean and standard deviation of
the number recorded?
