The probability is 0.1253.
This is binomial because 1) there are two outcomes (either do or do not use in class); 2) the events are independent of each other (the probability of one person using a phone in class does not affect the probability of another person doing this); and 3) there is a fixed number of trials (9).

Answer:
Step-by-step explanation:
Three eights
Answer:
50 degrees
Step-by-step explanation:
all inside angles in every triangle can be added up to equal 180 degrees.
this is a right angle, so one has to be 90 degrees
on the bottom right it's marked 140 degrees on the outside, in order to find the inside angle, you need to subtract 140 from 180, which gives you 40 degrees
180-90=90
90-40=50
so the answer is 50

3/7 . just take the square root of the top and bottom
The given equation is in point-slope form. The line that represents this equation passes through the point (4,1) and has a slope of (3/2).
One way to graph this quickly would be to plot the point (4,1). Move 2 units to the right from this point, and then (without picking up your pen) 3 units up. Plot a dot there. Connect the 2 points with a straight line.
