Answer:
Before we graph
we know that the slope, mx, could be read as
. To graph the the equation of the line, we begin at the point (0,0). From that point, because our rise is negative (-1), instead of moving upwards or vertically, we will move downards. Therefore, from point 0, we will vertically move downwards one time. Now, our point is on point -1 on the y-axis. Now, we have 2 as our run. From point -1, we move to the right two times. We land on point (2,-1). Because we need various points to graph this equation, we must continue on. In the end, the graph will look like the first graph given.
For the equation y = 2, the line will be plainly horizontal. Why? Because x has no value in the equation. The variable
does not exist in this linear equation. Therefore, it will look like the second graph below. We graph this by plotting the point, (0,2), on the y-axis.
Answer:
5.78% probability that exactly 2 of them use their smartphones in meetings or classes.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they use their smarthphone in meetings or classes, or they do not. The probability of an adult using their smartphone on meetings or classes is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
63% use them in meetings or classes.
This means that 
7 adult smartphone users are randomly selected
This means that 
Find the probability that exactly 2 of them use their smartphones in meetings or classes.
This is P(X = 2).


5.78% probability that exactly 2 of them use their smartphones in meetings or classes.
Answer:
Ex). 4/5; 6/10; 7/8
Step-by-step explanation:
What you need to do is count how many parts there are in total and then count how many are shaded. The amount that is shaded becomes your numerator and the all the parts are your denominator.

They could have the same measurements in base and height but they don't have to be the same. Lets take an example. Let's say the area was 80 units squared. The base could be 20 and the height could be 4 units. However, it could also have a base of 40 and a height of 2 unites. The base and height could be different, but the area can stay the same in certain situations
Answer: yes
Step-by-step explanation: I have this same problem, and you missed out the 2 in the top right of the g. That means g is squared. So basically a number multiplied by itself twice equals 36. 6×6 is multiplied by itself twice, so yes his reasoning is complete
