3384 . What is of an hour is a second?

A. 0.0025
B. 0.0256
C. 0.000126
D. 0.00027

View Answer	Favorite Question

Answer: Option D

Explanation:

To find out what fraction of an hour a second is, you can set up the following calculation:

Number of seconds in an hour / Number of seconds in a second

There are 60 seconds in a minute, and 60 minutes in an hour, so:

Number of seconds in an hour = 60 seconds/minute * 60 minutes/hour = 3600 seconds

Now, calculate the fraction:

Number of seconds in a second = 1 second

Fraction = 1 second / 3600 seconds = 1/3600

So, a second is 1/3600th of an hour.

To express it as a decimal, divide 1 by 3600:

1 / 3600 ≈ 0.00027777777 (rounded to six decimal places)

So, a second is approximately 0.00027777 of an hour.

Answer: Option C

Explanation:

To find the probability that an integer selected at random from those between 20 and 100 inclusive is a multiple of 15, we first need to count the number of multiples of 15 in that range and then divide it by the total number of integers in that range.

Step 1: Find the number of multiples of 15 between 20 and 100.

The first multiple of 15 in that range is 15 itself. The last multiple of 15 in that range is 90.

So, we need to count how many multiples of 15 are there between 15 and 90.

Using the formula for counting multiples in a range:

Number of multiples = (Last multiple - First multiple) / Common multiple

Number of multiples = (90 - 15) / 15 = 75 / 15 = 5

There are 5 multiples of 15 between 20 and 100.

Step 2: Find the total number of integers between 20 and 100.

To find the total number of integers in that range, we subtract the lower bound (20) from the upper bound (100) and add 1.

Total number of integers = 100 - 20 + 1 = 81

Now, we can calculate the probability:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

Probability = (Number of multiples of 15) / (Total number of integers) = 5 / 81

So, the probability that an integer selected at random from those between 20 and 100 inclusive is a multiple of 15 is 5/81.
