Since 1 inch is equal to 2.54 cm and the root grows 3.5 inches each month, we will do multiplication.
2.54 * 3.5 = 8.89
The plant root grows 8.89 centimeters each month.
Answer: 0.9961
Step-by-step explanation:
Given: Total choices to each question = 4
So, the probability that an answer is correct = 
Total questions = 20
i.e. n= 20
Let x be the binomial variable that represents the number of correct answers.
So, the probability that the student has at least 10 correct answers.

[By using cumulative binomial table]
Hence, the probability that the student has at least 10 correct answers = 0.9961
Answer:
The answer is 2:1 because ratio is just like simple division
Answer:

Step-by-step explanation:
Odd functions follow the relation of

Lets check for the most trivial value, does

Well these values both equal 0, so this is correct!
What about another value?

In-fact this is strictly defined for all values of sin. Meaning that this is an odd function.
