Chayton read a report that said the probability that a randomly selected American is left-handed is 14%.
He was curious how many left-handed students to expect in a class of 20 students.
He simulated 25 classes of 20 students where each student selected had a 0.14 probability of being left-
handed.
Chayton counted how many left-handed students were in each simulated class. Here are his results:

P(2 or fewer left-handed) = 9/25 = 0.36

Step-by-step explanation:

From Chayton simulations, we can see that in 9 simulations there are 2 or fewer left-handed students in a class of 20 students. He simulated 25 classes of 20 students, then the probability to find 2 or fewer left-handed is: 9/25 = 0.36

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
