Sin(x)= 4/5 dilated by 2

1 answer:

6 0

It would remain the same (4/5). Sin of the angle is unchanged regardless of the size; it is a ratio related only to the angle, not the size of the triangles.

Answer:

a) Frequency table:

Category Frequency

Dog 4

Cat 3

Fish 2

Hamster 1

b) Relative frequencies of each animal type

Dog: 4/10 = 0.4
Cat: 3/10 = 0.3
Fish: 2/10 = 0.2
Hamster: 1/10 = 0.1

c) Popularity

Dog is the most popular because it has the highest relative frequency.

Hamster is the least popular because it has the lowest relative frequency.

Explanation:

a. Make a frequency table for the results.

There are four kind of pets: dog, cat, hamster, and fish.

A frequency table shows the number of items for each category (kind of pets).

Count the number of each kind of pet:

Dog: 4
Cat: 3
Hamster: 1
Fish: 2
Total: 10

With that you build your frequency table.

Frequency table:

Category Frequency

Dog 4

Cat 3

Fish 2

Hamster 1

b. Relative frequencies of each animal type.

The relative frequency is how often an outcome appears divided by the total number of outmcomes.

Here the total number of outcomes is 10 (the ten pets).

So, calculate each relative frequency:

Dog: 4/10 = 0.4
Cat: 3/10 = 0.3
Fish: 2/10 = 0.2
Hamster: 1/10 = 0.1

An important feature of the relative frequency is that they must add up 1. Check:

0.4 + 0.3 + 0.2 + 0.1 = 1.

c. Using the relative frequencies explain which animals are most and least popular.

Popularity is determined by the frequency with each outcome is repeated. The most popular is the most repeated. The least popular is the least repeated.

Dog is the most popular because it has the highest relative frequency.

Hamster is the least popular because it has the lowest relative frequency.

Answer:

Volume = ( About ) 2406.165 cm^3

Step-by-step explanation:

If you consider a cube or a rectangular prism, you could identify it's volume through the multiplication of it's Base by height. A pyramid has 1 / 3rd that volume, so in order to take a volume of the figure to the left, we would multiply Base * height and take 1 / 3rd of that;

$Square Pyramid,\\Base ( Square ) = a^2, a = length = 17.2 cm\\Height = 24.4 cm\\\\Volume = 1 / 3 ( Base ) ( Height ),\\Volume = 1 / 3 ( ( 17.2 )^2 )( 24.4 ),\\Volume = 1 / 3( 295.84 )( 24.4 ),\\\\Volume = 98.6133333333( 24.4 ),\\Volume = 2406.16533333,\\\\Volume = ( About ) 2406.165$

Solution ⇒ ( About ) 2406.165 cm^3

Hope that helps!

3/5 ton elmanın 1/4'ü satılmıştır. Buna gore geriye kaç kilogram elma kalmiştır?

Troyanec [42]

Cevap:

450 kilo

Adım adım açıklama:

Verilen:

Toplam elma tonu = 3/5 ton

Satılan kısım = 1/4 ton

Tonlarca elma kaldı;

(Toplam ton - satılan ton)

Satılan ton:

Satılan kısım * toplam ton

(1/4 * 3/5) ton

3/20 ton

Ton kaldı:

Toplam ton - satılan ton

(3/5 - 3/20)

L.C.M 5 ve 20 = 20

(12 - 3) / 20

9/20 ton

Tonları kg'a çevirmek:

1 ton = 1000 kg

Bu nedenle

9/20 ton = (9/20) * 1000

= 9000/20

= 450 kg
