In a group of eighteen people, each person shakes hands once with each other person in the group. How many handshakes will occur

miv72 [106K]

The number of handshakes that will occur in a group of eighteen people if each person shakes hands once with each other person in the group is 153 handshakes

In order to determine the number of handshakes that will occur among 18 people, that is, the number of ways we can choose 2 persons from 18 people.

∴ The number of handshakes = $^{18}C_{2}$

$^{18}C_{2} = \frac{18!}{(18-2)!2!}$

$^{18}C_{2} = \frac{18!}{16!2!}$

$^{18}C_{2} = \frac{18\times17\times16!}{16!\times2!}$

$^{18}C_{2} = \frac{18\times17}{2\times1}$

$^{18}C_{2} = \frac{306}{2}$

$^{18}C_{2} = 153$

∴ The number of handshakes = 153 handshakes

Hence. 153 handshakes will occur in a group of eighteen people if each person shakes hands once with each other person in the group.

How do you solve y=10x-18?

Snowcat [4.5K]

Answer:

y=10x−18

Step 1: Flip the equation.

10x−18=y

Step 2: Add 18 to both sides.

10x−18+18=y+18

10x=y+18

Step 3: Divide both sides by 10.

10x /10 = y +18/10

x= 1/10 y + 9/5

Answer:

x= 1/10 y + 9/5

Suppose you have a random variable that is uniformly distributed between 7 and 26. what is the expected value for this random va

Daniel [21]

$\mathbb E(X)=\int_7^{26}\dfracx{26-7}\,\mathrm dx=\dfrac{33}2=16.5$

which follows from the definition for expected value,

$\mathbb E(X)=\int_{-\infty}^\infty xf_X(x)\,\mathrm dx$

where $f_X(x)$ is the probability density function for $X$ .
