Answer: Y= -2/3x -3
Explanation: The formula is y-y1=m(x+b).
Fill in what we know, which is,
y-(-5)=-2/3 (x-3) Then you distribute and get y+5=-2/3x+2. Then you subtract 5 from each side and get your final answer of y=-2/3x -3

Step-by-step explanation:
When adults with smartphones are randomly selected, 61% use them in meetings or classes, then
- the probability of using the smartphone is
- the probability of not using the smartphone is
If 8 adult smartphone users are randomly selected, the probability that exactly 3 of them use their smartphones in meetings or classes can be calculated using binomial distribution as
Note that
then the probabilty is
