Answer:
The answer is below
Step-by-step explanation:
We have the following information:
Number of songs you like = 2
Total number of songs = 12
a) P(you like both of them) = 2/12 x 1/11 = 0.015
This is unusual because the probability of the event is less than 0.05
b) P(you like neither of them) = 10/12 x 9/11 = 0.68
c) P(you like exactly one of them) = 2 x 2/12 x 10/11 = 0.30
d) If a song can be replayed before all 12,
P(you like both of them) = 2/12 x 2/12 =0.027
This is unusual because the probability of the event is less than 0.05
P(you like neither of them) = 9/12 x 9/12 = 0.5625
P(you like exactly one of them) = 2 x 2/12 x 9/12 = 0.25
9 4/21
Hope this helps, i apologize if i’m incorrect
Answer:
10 miles
Step-by-step explanation:
Given: Boat goes 
hours with 8 mph (i)
Boat goes 
hours with 12 mph (ii)
Now, lets find out distance separately to get total distance.
Formula for finding distance is
D= 
D= 
(i)
D= 
∴ D1= 6 miles (i)
D= 
(ii)
∴D2= 4 miles (ii)
To find total distance, we will add d1 and d2
Total distance = 
∴ Total distance = 
= 10 miles is the total distance covered by boat in all this time.
Answer:
y = 2x + 3
Step-by-step explanation:
the same slope would be 2x still
the 3rd and 4th choice are the only ones that have the correct slope
and 1 unit lower than 4 is 3
