What is the value of 10C3?

Zigmanuir [339]

The answer is B. 120

nCr = n! / ((r! * (n - r)!)

n = 10
r = 3

10C3 = 10! / ((3! * (10 - 3)!)
= 10! / ((3! * 7!)
= (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1 * 7 * 6 * 5 * 4 * 3 * 2 * 1)
= 3628800 / 30240
= 120

Find all the real cube roots of -0.000125

Ira Lisetskai [31]

We have the value -0.000125

Since this is negative value the cube number cannot be positive since it will not give an negative answer

hence the answer should be a negative number

this already eliminates the option A, B and D

now we have

$\sqrt[3]{-0.000125}$

$\sqrt[3]{(-0.05).(-0.05).(-0.05)}$

=-0.05 (option C)

21 22 23 24 25 TIME REMAINING 01:40:27 A hat contains slips of paper with the names of the 26 other students in Eduardo’s class

Pani-rosa [81]

There are 26 - 10 = 16 girls. The number of ways to choose 2 girls from a set of 16 is C(16, 2) = 120. (Your class might be using a different notation for combinations, like $_{16}C_2$ .)

The number of ways to choose 2 people (boys or girls) from a set of 26 is C(26, 2) = 325.

The probability of choosing 2 girls is $\frac{120}{325} = \frac{24}{65}$

Example: how to compute C(16,2):

$C(n, r) = \frac{n!}{r!(n-r)!} \\ C(16, 2) = \frac{16!}{2!(16-2)!} \\ =\frac{16!}{2! \times 14!} \\ =\frac{16\times 15}{2\times 1} \\ =120$
