A plant grows 3 centimeters in 10 days. How much does it grow per day? Write your answer as a fraction in simplest form
2 answers:
Answer:
The plant grows 3/10 centimeters per day
Step-by-step explanation:
This question can be solved using a simple rule of three.
In 10 days, it grows 3 centimeters. In 1 day, it grows x centimeters. We have to find x. So
10 days - 3 centimeters
1 day - x centimeters.
The plant grows 3/10 centimeters per day

Answer:
C. If the probability of an event occurring is 1.5, then it is certain that the event will occur.
Step-by-step explanation:
Probability is a value between <em>0 and 1</em> (including both values). Thus, to say that there is a probability of 1.5 is not correct, and, therefore, this statement is not true.
We can rewrite the statement as "If the probability of an event occurring is 1, then it is completely certain that the event will occur."
Statement A.
Suppose the event is A. Then, if P(A) = 0, it is completely certain that the event will not occur. It is true.
Statement B.
. Then, the statement is true.
Statement C.
We already explained the <em>statement C is not true</em> because the values for probabilities are between 0 and 1 (including both values). A probability of 1.5 is meaningless as a result.
Statement D.
For the same reason explained in C, the probability can never be a negative value. So, this statement is also true.
