Tom got $50 and Jane got $60 dollars because If you add 50 to 190, it gives you 240 and 60 + 60 = 120 which is half of 240

Determine the number of handshakes, i, that will occur for each number of people, n, in a particular room. (people)

Answer:

$S_n = \frac{n}{2}(n - 1)$

Step-by-step explanation:

Given

For 5 people

$\begin{array}{cc}{People} & {Handshakes} & {5} & {4} & {4} & {3} & {3} & {2} & {2} & {1} & {1} & {0} &{Total} & {10} \ \end{array}$

Using the given instance of 5 people, the number of handshakes can be represented as:

$(n - 1) + (n - 2) + (n - 3) + ........ + 3 + 2 + 1 + 0$

The above sequence is an arithmetic sequence and the total number of handshakes is the sum of n terms of the sequence.

$S_n = \frac{n}{2}{(T_1 + T_n})$

Where

$T_1 = n - 1$ --- The first term

$T_n = 0$ --- The last term

So:

$S_n = \frac{n}{2}(n - 1 + 0)$

$S_n = \frac{n}{2}(n - 1)$

The solution set of the inequality 2x − y > 2 consists of all the points __ ? the line __ ?

GalinKa [24]

Answer:

b - below; y = 2x − 2

Step-by-step explanation:

2x − y > 2
2x - y + y - 2 > 2 + y - 2
2x - 2 > y
y < 2x - 2

Solution is the points below the line y = 2x - 2

<u>Correct option is:</u>

b - below; y = 2x − 2
