1.) Research done by Gizmodo Electronics found that 82% of shoppers in their store consult their phone while shopping. If 12 shoppers in their store are surveyed, what is the probability exactly 5 of them say they consult their phone while shopping in Gizmodo Electronics?

2.) Suppose you are taking a 17 question True/False quiz which you are not prepared for. You find yourself simply guessing at every answer. What is the probability that you get less than 4 answers correct?

3.)Suppose you are taking a True/False quiz that has 20 questions on it. You are not prepared for this quiz and so you just guess at every answer. What is the probability that you get more than 13 questions correct?

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
