5 times because with common denominaters(remeber:what you do the top you always do to the bottom or what you do the bottom you do to the top)7/8=21/24 1/6=4/24.21 divided by 4 equals 5.5 but you want a whole loaf of cheese bread not a half so you would round it to 5.

Answer: $3^1^1\\$

Step-by-step explanation:

$\frac{81^4}{3^5}$

$\frac{3^1^6}{3^5}$

The base is same power can be add or subtract

$3^1^6^-^5$

What is the area of the polygon? Show your work.

koban [17]

Answer:

33 square units

Step-by-step explanation:

Assuming that each line on this grid increases by a value of one, the area of the polygon can be determined by breaking it down into a large rectangle and two smaller triangles.

<h3>Area of the rectangle</h3>

The area of a rectangle is simply $A = bh$ , where b represents the base and h represents the height.

Counting the size of each side, we can determine that they are 6 units for the base and 4 units for the height.

Substituting in the values, we get:

$A = (6)(4)\\A = 24$

The area of the rectangle is 24 square units

<h3>Area of the triangles</h3>

The area of a triangle is simply $A = \frac{1}{2} bh$ .

The base of each triangle is 3, and the height of each triangle is also 3.

Substituting in the values, we get:

$A = \frac{1}{2} (3)(3)\\A = \frac{1}{2} (9)\\A = 9 / 2\\A = 4.5$

The area of each triangle is 4.5 square units

<h3>Area of the polygon</h3>

To get the area of the polygon, we simply add up the area of the rectangle and both triangles

$A = 24 + 4.5 + 4.5\\A = 24 + 9\\A = 33$

The total area of the polygon is 33 square units.

Answer:

a) (1,2), (1,3), (1,4), (1,5), (2,3), (2,4),(2,5),(3,4), (3,5) and (4,5)

PX(0) = 0.3

PX(1) = 0.6

PX(2) = 0.1

F(x) = 0 if x<0
F(x) = 0.3 if 0 ≤ x < 1
F(x) = 0.9 if 1 ≤ x < 2
F(x) = 1 if x ≥2

Step-by-step explanation:

Lets call the boards 1,2,3,4 and 5

a) There are ${5 \choose 2} = 10$ possible outcomes: (1,2), (1,3), (1,4), (1,5), (2,3), (2,4),(2,5),(3,4), (3,5) and (4,5).

b) X is 0 if the selected boards doesnt contain 1 or 2. There are ${3 \choose 2} = 3$ possibilities for this, in concrete, (3,4), (3,5) and (4,5).

PX(0) = 3/10 = 0.3

There is only 1 possibility so that X = 2, which is (1,2), therefore

PX(2) = 1/10 = 0.1

In any other case (there are 6 remaining), X will be equal to 1, so

PX(1) = 6/10 = 0.6

Therefore, X has the following distribution

PX(0) = 0.3

PX(1) = 0.6

PX(2) = 0.1

c) F(0) = 0.3

F(1) = 0.3+0.6 = 0.9

F(2) = 1

We have, as a consequence

F(x) = 0 if x<0
F(x) = 0.3 if 0 ≤ x < 1
F(x) = 0.9 if 1 ≤ x < 2
F(x) = 1 if x ≥2
