When you add up the sum of the digits, it should be a multiple of three. 21 is 2 plus 1 equals 3, so since 3 is a multiple of three, 21 is divisible by 3
Answer: 0.500
Step-by-step explanation:
Given : A normal distribution has a mean
of 10 and a standard deviation
of 1.
Let x be a random variable that represents numbers .
The probability of selecting a number that is at most 10 will be
As the area occupied by standard normal curve less than equal to 0 = 0.500
So, required probability = 0.500
The least common multiple is the smallest term that can be divided to both terms without any remainder. For the two terms 8c^4 and 6c^2, you can determine it into two part. First, you find the LCM for 8 and 6. You find the prime number that is common between the two. That would be 2. For the variables c^4 and c^2, the 'prime variable' is c. Therefore, the least common multiple for 8c^4 and 6c^2 is 2c.
Express each ratio as a fraction in simplest form.2 yards to 45 feet
First, let's convert feet to yard to get the answer
=> 2 yard = x yard
=> 1 foot = 0.333333 yard.
=> 0.333333 yard * 45 = 15 yards, thus the answer is
