Answer:

Displacement is a straight line from the starting point to the finish point 6\sqrt{2} blocks in<u> North-West</u> direction.

Step-by-step explanation:

The figure below shows the movement of person and standard direction taken.

AB represents the movement of person 6 blocks towards north and BC represents the movement of person 6 blocks towards west. A to C defines the distance traveled by the person.

Displacement is defined as the shortest distance covered between two points.

Here, displacement is the distance between point A and C.

Since, angle at B is right angle So, ΔABC is a right angled triangle.

Pythagoras theorem states that in a right angled triangle sum of square of base and perpendicular is equal to the square of hypotenuse.  

Applying Pythagoras theorem in ΔABC, we get

(AC)^2=(AB)^2+(BC)^2

(AC)^2=(6)^2+(6)^2

(AC)^2=36+36

AC=\sqrt{72}

AC=6\sqrt{2}

Thus, displacement is a straight line from the starting point to the finish point 6\sqrt{2} blocks in <u>North-West</u> direction.

For the answer to the question above, A person drives north 6 blocks, then drives west 6 blocks. the displacement is a straight line from the starting point to the finish in <span>8.49 blocks</span> in a Northwest <span>direction.
The Solution:
</span>A^2+B^2=C^2

6*6+6*6 = sqrt(72)

Missing part of the question

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)

A sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 10 cars needs to
Archy [21]

Answer:

0.2916, 0.1488, 0.0319

Step-by-step explanation:

Given that a sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 10 cars needs to have oil added.

Since each trial is independent there is a constant probability for any random car to need oil is 0.10

Let X be the number of cars that need oil

A) Here X is BIN(4,0.1)

P(X=1) = 4C1(0.1)(0.9)^3 \\= 0.2916

B) Here X is Bin (8, 0.1)

P(x=2) = 8C2 (0.1)^2 (0.9)^6\\\\=0.1488

C) Here X is Bin (20,5)

P(x=5) = 20C5 (0.1)^5 (0.9)^{15} \\=0.0319
