Which is the slowest rotating planet?

A. A. Mars

B. B. Venus

C. C. Jupiter

D. D. None of these

Correct answer is: B. B. Venus

Venus is the slowest rotating planet in our solar system, taking 243 Earth days to rotate once on its axis. This means that Earth rotates 243 times for every one rotation of Venus. Venus also rotates in the opposite direction to Earth, so the sun rises in the west and sets in the east on Venus

A sequence is called Arithmetic if it has:

A. A. Addition

B. B. Common difference

C. C. Common ratio

D. D. None of these

Correct answer is: B. B. Common difference

A sequence is arithmetic if the common difference of all terms of a sequence is the same.

A sequence is geometric if the common ratio of all terms of sequence is the same.

A common difference is the difference between consecutive numbers in an arithmetic sequence

Arithmetic mean between x -3 and x + 3 is:

A. A. -6

B. B. 6

C. C. x

D. D. None of these

Correct answer is: C. C. x

The arithmetic mean between any two numbers is simply the average of those two numbers.

In this case, the two numbers are x - 3 and x + 3.

Therefore, the arithmetic mean between x - 3 and x + 3 is:

(x - 3 + x + 3) / 2

Simplifying the equation:

2x / 2

This cancels out the 2s, leaving us with:

x

So, the arithmetic mean between x - 3 and x + 3 is simply x.

A single A.M between a and b is:

A. A. (a+b)/2

B. B. =_/ab

C. C. 2ab/(a+b)

D. D. None of these

Correct answer is: A. A. (a+b)/2

The arithmetic mean (A.M) between any two numbers a and b is (a+b)/2.

If we want to find a single arithmetic mean between a and b, we can set up an equation such that:

A.M = (a+b)/2

But since we are looking for a single A.M between a and b, we don’t know the exact value of the A.M. Therefore, we cannot solve for it using this equation.

However, we can make an observation that any value between a and b will be an arithmetic mean between a and b. Therefore, we can say that there are infinitely many single arithmetic means between any two numbers a and b

Sum of 4 A.M between 18 and 3 is:

A. A. 15

B. B. 12

C. C. 42

D. D. None of these

Correct answer is: C. C. 42

<h3 class="wp-block-heading"><a href="https://mcqsplanet.com/2023/03/21/sum-of-4-a-m-between-18-and-3-is/#panel-1"> +</a></h3>

The arithmetic mean (A.M) between any two numbers a and b is (a+b)/2.

So, the arithmetic mean between 18 and 3 is:

(18 + 3)/2 = 21/2 = 10.5

To find the sum of 4 arithmetic means between 18 and 3, we can use the formula:

Sum of n A.M = n x A.M

Substituting the values, we get:

Sum of 4 A.M = 4 x 10.5 = 42

Therefore, the sum of 4 arithmetic means between 18 and 3 is 42.
