Answer:

20÷10=2. 10,000÷10=1,000

Therefore, the probability of two randomly selected chips being defective is 2 in 1,000 or 2/1,000

Emily says she can prove the Pythagorean Theorem using the following diagram. She explains that she can divide the squares on th
irinina [24]

Answer: Yes, It is

Step-by-step explanation:

Demonstrating the Pythagorean Theorem

When you think of each side of a right triangle as also being a side of a square that's attached to the triangle. The area of a square is any given side multiplied by itself. (For example, b x b = b^2).

In order to show that a^2 + b^2 = c^2,

follow these steps:

Get a right triangle on grid paper that you can print. You'll also need scissors, and a ruler.

Cut out the triangle.

Make three squares with sides that are equal to each side of the triangle. Begin with side

a. Measure the length of side a. On the blank piece of grid paper,

- draw a square with sides that are the same length as side a.

- Label this square a2.

- Repeat these steps to create squares for sides b and c. (If you don't have a ruler, just use the triangle as a guide; trace the length of one side, and then draw three more sides of the same length to make a square.)

Cut out the squares. Place each square next to the corresponding sides of the triangle.

Now show that a2 + b2 = c2. Place the squares made from sides a and b on top of square c. You will have to cut one of the squares to get a perfect fit.

Area of Whole Square

The total area of a big square, where each side having a length of a+b, is:

A = (a+b)(a+b)

Area of The Pieces

By adding up the areas of all the smaller pieces:

First, the smaller (tilted) square has an area of:c^2

Each of the four triangles has an area of: ab^2

So all four of them together is: 4ab^2 = 2ab

Adding up the tilted square and the 4 triangles gives: A = c^2 + 2ab

Both Areas Must Be Equal

The area of the large square is equal to the area of the tilted square and the 4 triangles. This can be written as:

(a+b)(a+b) = c^2 + 2ab

By rearrange this, we shall see if we can get the pythagoras theorem:

Start with:(a+b)(a+b) = c^2 + 2ab

Expand (a+b)(a+b): ag2 + 2ab + b^2 = c^2 + 2ab

Subtract "2ab" from both sides: a^2 + b^2 = c^2

Therefore, it's been proven that, a^2 + b^2 = C^2

A salesperson records the number of miles she travels each week. The table below shows the number of miles the salesperson trave
drek231 [11]

Answer:

The mean

Step-by-step explanation:

Given :

Miles traveled : 216 210 250 225 209

Ordered data : 209, 210, 216, 225, 250

Mean = Σx / n

Sample size, n = 5

Mean = (216 + 210 + 250 + 225 + 209) / 5

Mean = 222 (mean for the 5 weeka.

The median :

1/2(n+1) th term = 6/2 = 3rd term

.Median = 216

Adding week 6 data:

209, 210, 216, 225, 250, 406

Mean = ( 705/ 6) = 192

Median :

1/2(n+1) th term = 7/2 = 3.5 th term

.Median = (216 +. 225) /2 = 220.5

The mean changes more :

220 - 192 = 28

Median :

220.5 - 216 = 4.5:
