Answer:
1. y=5/2x+4
2. y=-7x-3
Y=mx+b is slope intercept form
Step-by-step explanation:
You have to add it in the slope intercept formula
2. M=-7 and B=-3
so y=-7x-3
M = 5/2 B = 4
So y = 5/2x+4
Answer:
P(A) = 44.44%
P(B) = 50%
P(B|A) = 37.5%
P(B|A) different from P(B).
A and B are independent.
Step-by-step explanation:
If we have a total of 180 students, and 80 of them have a Playstation, we have that P(A) = 80/180 = 0.4444 = 44.44%
If we have 90 students that have a Xbox, we have that P(B) = 90/180 = 0.5 = 50%
If we have 30 students that have both consoles, we have that P(A and B) = 30/180 = 0.1667 = 16.67%
To find P(B|A), we will find for a student that has an Xbox inside the group of students that has a Playstation, that is, we have 30 students in a total of 80 students, so P(B|A) = 30/80 = 0.375 = 37.5%
P(B|A) is different from P(B), the first is 37.5% and the second is 50%, so events A and B are independent events.
Answer:
- 
Step-by-step explanation:
Evaluate cosπ then inverse tan, that is
cosπ = - 1
(- 1) = -
