Of all sixth graders, 70% sent a text
message yesterday. ten trials of a
simulation are conducted and the
data are recorded below.
62072, 34570, 80983, 04292, 83150,
36330, 96268, 14077, 77985, 13511
the numbers 0 through 6 represent
students who sent a text yesterday,
and the numbers 7 through 9
represent students who did not send
a text yesterday.
based on the simulated data, what
is the probability that 3 or more
of a group of 5 students randomly
selected will send a text today?
explain.

16 more than the product of 5 and p

What is the slope of the equation y =

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
