Answer: 36 miles per hour (mph)
We have 12 miles traveled in 1/3 of an hour
Multiply both values by 3 so that the "1/3 hr" becomes "1 hr"
12*3 = 36
(1/3)*3 = 1
So you travel 36 miles in one hour, ie your speed is 36 miles per hour.
You can use this ratio to help
12 miles : 1/3 hr
3*(12 miles) : 3*(1/3) hr
36 miles : 1 hr
Answer:
0.24
Step-by-step explanation:
These events are not mutually exclusive; this means they can happen at the same time.
For two events A and B that are not mutually exclusive,
P(A and B) = P(A) * P(B|A)
Let A be the event "over 21 years old" and B be the event "drinks alcohol".
The probability that a student is over 21 years old is 0.3; this is because 30% of the students are over 21 years old.
The probability that a student drinks alcohol given they are over 21 is 0.8.
This gives us
P(A and B) = 0.3(0.8) = 0.24
-15/-21 -14/x
-15x = -21 * -14
x = -19.6
answer -14c = -19.6 or about -20
answer 3c = .6 or about 1
formula would be
y= 1.2x -3
partial variation means the line doesn't go through (0,0)
