To solve this problem, work out the problem normally as if the "≥" is "=".
3.1v - 1.4 ≥ 1.3v + 6.7
-1.3v -1.3v
________________
1.8v - 1.4 ≥ 6.7
+1.4 +1.4
________________
1.8v ≥ 8.1
___ ___
1.8 1.8
v ≥ 4.5, is the answer.
The d=rt formula is used in this situation where d=distance, r= speed, and t= time.
So plug in your variables and numbers to get;
distance=400*h
Hope this helps.
Answer:
The probability that you will get 3 pictures right is 0,015625
Step-by-step explanation:
To get the probability, equally likely, of guessing the picture we use the following formula
P=# of possibilities that meet the condition / #of equally likely possibilities.
# of possibilities that meet the condition= 2
#of equally likely possibilities= 8
So every time you guees you have 2 possibilities from 8 , that give us a probability of 2/8 or 1/4
We suppose once you guess 1 card , the tester put back the card with the others.
Now, we must guess 3 pictures, that will be the multiplication of each probability.
P= 1/4 *1/4*1/4
P= 0,015625
