This is a combination in which you choose 4 from 10.
The formula is
combinations = 10! / 4! * (10-4)!
combinations = 10! / 4! * 6!
combinations = 10 * 9 * 8 * 7 * 6! / 4! * 6!
combinations = 10 * 9 * 8 * 7 / 4 * 3 * 2
combinations = 10 * 3 * 7
combinations = 210

N is a negative integer, and p is a positive integer.
mart [117]

Answer:

Option C) The two quantities are equal.

Step-by-step explanation:

We are given the following in the question:

n is a negative integer and p is a positive integer.

Quantity A: The product of the integers from n to p

Quantity B: 0

Quantity A is the product of integers from n to p. Since all the integers from n to p will include zero between them, thus the product of all the integers from n to p will be zero.

The product takes place in the following manner:

-n_x\times -n_{x-1}\times....\times -n_1\times 0\times p_1\times...\times p_{y-1}\times p_y = 0

Thus, both the quantities are equal.

Option C) The two quantities are equal.

7th term in geometric sequence an=2 5(n-1)
Soloha48 [4]
To find the 7th term, all you have to do is plug it in the equation.

First n would equal 7 because we are looking for the 7th term.

Now, let's plug everything we know into the equation.

a7 = 2+5 * (7-1)

= 2 + 5 * 6

= 2 + 30

= 32

In conclusion, the 7th term would equal 32.
