Jack did an experiment where he pulled a marble from a bag
and flipped a coin. He did the experiment 50 times. Here are
his results:
MARBLE
Red: 12
Blue: 22
Green: 16
COIN
Heads: 20
Tails: 30
What is the COMPOUND probability that Jack will
pull a red marble AND the coin landing on tails?

Find the length of the normal and the angle it makes with the positive x-axis. (see pictured below)

The graph shows the decibel measure for sounds depending on how many times as intense they are as the threshold of sound. noise in a quiet room is 500 times as intense as the threshold of sound. what is the decibel measurement for the quiet room? 20 decibels28 decibels200 decibels280 decibels

Aboat has a speed of 9 mph in calm water. it takes the boat 4 hours to travel upstream but only 2 hours to travel the same distance downstream. which equation can be used to find c, the speed of the current? 2(9 – c) = 4(9 + c) 9 + c = 4(9 – c) 9 – c = 2(9 + c) 4(9 – c) = 2(9 + c)
