3. Assume you have a button which is subject to bounces which last 10-20ms. An actual button press lasts between 100 and 150 ms and two button presses are separated by at least 300 ms. The system should turn on an LED while the button is pressed and turn it off when the button is released. It should not react to bounces. Assume a sampling rate of 30 ms. Draw a state machine which represents this system (button presses with values of 0 or 1 are your input, and the LED being 1 (on) or 0 (off is our output). (20 points)

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
