Kayl wants to find the radio wave length of his favorite radio station. The formula to use is A=c/f. A=wave length
C=speed of light
F=frequency

If c=3×10^8m/sec (the speed of light) and f=1.007×10^8 Hz (his radio station is 100.7 KISS), what is the wave length of his radio station?

A=2.979m
B=2.993m
C=2.979 × 10^8m
D=2.993 × 10^8m

Asimple random sample of size nequals14 is drawn from a population that is normally distributed. the sample mean is found to be x overbar equals 70 and the sample standard deviation is found to be sequals13. construct a 90% confidence interval about the population mean

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.

Use circumcenter theorem to solve for the given values
