Step-by-step explanation:
Answer:
0.95 = 95% probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS
Step-by-step explanation:
We solve this question treating these probabilities as Venn sets.
I am going to say that:
Event A: Requesting automatic transmission
Event B: Requesting built-in GPS
90% of all buyers request automatic transmission
This means that
82% of all buyers request built-in GPS
This means that
77% of all buyers request both automatic transmission and built-in GPS.
This means that
What is the probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS
This is , which is given by:
So
0.95 = 95% probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS
Answer:
it's true! it's easier to solve for y because there's no coefficient in front of it unlike the second one that has "9y."
Step-by-step explanation:
30=-5(6n+6)
30=-5×6n-5×6
30=-30n-30
30+30=-30n
60=-30n
60/-30=-30n/30
-2=n
