For every two non-school days a week, there are five school days; 2:5.

<h3>What is ratio?</h3>

Ratio can be defined as a mathematical expression that is typically used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

<h3>What is a proportion?</h3>

A proportion can be defined as an expression which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.

In this exercise, you're required to write a ratio that directly matches the given situation. For every two non-school days a week translates to 2, while there are five school days translates to 5.

For every two non-school days a week, there are five school days; 2:5.

You survey your class to find out the types of pets they have at home. Below are the results: Dog, Dog, Cat, Cat, Cat, Dog, Hams
Fynjy0 [20]

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:

<u>a. Make a frequency table for the results.</u>

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

A <em>frequency table </em>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

<u>b. Relative frequencies of each animal type.</u>

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.

<u>c. Using the relative frequencies explain which animals are most and least popular.</u>

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.

Complete this statement 36x^3a +45xa^2=9a( )
Snezhnost [94]
If 36x^3a+45xa^2=9a()  then 9a is a factor the other factor, (), is the left side divided by 9a

(36x^3a+45xa^2)/(9a)

4x^3+5xa

So the () term is (4x^3+5xa)

When a​ car's tire pressure is 30 pounds per square inch​ (psi), it averages 20.5 mpg of gasoline. If the tire pressure is incre
bearhunter [10]

For A, divide total miles by the miles per gallon for each tire pressure to find the number of gallons of gas used:

At 30 psi: 23000 / 20.5 = 1121.95 gallons , round to 1121 gallons.

At 35 psi: 23000 / 21.1 = 1090 gallons.

Number of gallons saved: 1121 - 1090 = 31 gallons.

B) multiply the cost per gallon by the number of gallons saved:

31 gallons x $2.00 = $62.00 saved.

C) Multiply the gallons saved by 1 car by total number of cars:

31 gallons x 140 million cars = 4,340 million gallons ( 4 billion 340 million gallons)
