The answer of this expression is - 4 1/6
Answer:
0.298
Step-by-step explanation:
in this case we have an exponential distribution:
1 - e ^ (- x / y)
where x and y corresponds to the times we find in the exercise.
Now follows memoryless property.
P (More than 23 additional minutes | 20 minutes passed)
P = P (More than 23 minutes)
P = 1 - P (Less than or equal to 23 minutes)
P = 1 - (1 - e ^ (- 23/19))
P = 0.298
Therefore the probability is 29.8%
A SCATTER PLOT IS JUST A DOT PLOT
Answer:
15 per hour
Step-by-step explanation:
120 people / 8 hours = 15 peeps per hour!
Y = x +2
You would find this by finding the slope first. Slope is (y2 - y1) / (x2-x1) = (6-2) / (4-0) or 4/4 = 1. the slope is 1. From the point (0, 2) you can tell that the y intercept is 2. Therefore you get the equation y = x+2
