A true proportion is an equation that states that two ratios are equal. If you know one ratio in a proportion, you can use that information to find values in the other equivalent ratio.
An employee of an auction house has a list of 25 recently sold paintings. Eight artists were represented in these sales. The sale price of each painting is on the list. Would the correlation coefficient be an appropriate way to summarize the relationship between artist (x) and sale price (y)? Why or why not?
Answer:
Step-by-step explanation:
Given that:
A list of 25 recently sold paintings in an auction house is available, and eight artists were represented in the sales.
The objective is to determine if the correlation coefficient would be an appropriate way to summarize the relationship between the artist (x) and sale price (y).
From the information given;
NO, The correlation coefficient would not be an appropriate way to summarize the relationship between artist (x) and sale price (y).
The reason is being that since variable (x) is the artist and which is regarded as the categorical variable even though it is attributed to numerical values, it cannot and will not be used in quantitative studies like correlation.
On a photograph an ant is enlarged at a scale 25:1. In the photo, the ant's leg is 15 cm. What is the actual length of the ant's leg?
Answer:
3/5cm
Step-by-step explanation:
Let's solve your equation step-by-step.
x(25)=15
Step 1: Simplify both sides of the equation.
25x=15
Step 2: Divide both sides by 25.
25x /25 = 15/25
x = 3/5
Actual length of ant's leg is 0.6cm
Let the actual length of ant's leg = a
Scale = 25 : 1
Length in photo = 15 cm
Express as a an equation :
25 × actual length = 1 × length in photo
25a = 15
a = 15 / 25
a = 0.6
Hence, actual length of ant's leg is 0.6cm

Answer:
Option 4: [tex]3\frac{3}{18}[/tex] is the correct answer.
Step-by-step explanation:
The given fractions are mixed fractions. the mixed fractions have to be converted into proper fractions before performing any operation like addition, subtraction etc.
Given fractions are:
[tex]5\frac{3}{6}-2\frac{1}{3}[/tex]
Converting into proper fractions
[tex]=\frac{33}{6} - \frac{7}{3}[/tex]
Making the denominator same
We have to multiply first fraction by 3 and second by 6
[tex]=\frac{33*3}{6*3} - \frac{7*6}{3*6}\\=\frac{99}{18}-\frac{42}{18}\\=\frac{99-42}{18}\\= \frac{57}{18}[/tex]
Converting into mixed fraction: [tex]=3\frac{3}{18}[/tex]
Hence,
Option 4: [tex]3\frac{3}{18}[/tex] is the correct answer.

The total number of students enrolled at Twin Rivers Middle School is 2,000
students. If the ratio of boys to girls is also 3 to 2 for the school, how many students
are boys and how many students are girls at Twin Rivers Middle school?
Answer:
1200 boys and 800 girls
Step-by-step explanation:
since the ratio is 3:2 i just added the ratio to get 5 then divided that by how many total students there were giving me 400, then multiplied it by 3 for the boys and by 2 for the girls. giving me 1200 and 800
(sorry if this is confusing)
Add the ratios together: 3 + 2 = 5
Divide total students by 5:
2000 / 5 = 400
Multiply each ratio by 400:
Boys = 400 x 3 = 1200
Girls = 400 x 2 = 800

The situation can be represented as an algebraic expression as:
y = x + 6
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
Given that,
Bernadette bought six more fish for her tank,
Suppose, Bernadette has x number of fish already
the expression for the total number of fees can be written as,
Total number of fees = Number of fees he has already + 6
= x + 6
⇒ y = x + 6
Hence, the given condition can be expressed as y = x + 6

The length of one side of a square pond is 15 feet. The pond is surrounded by a 3 foot wide walkway. What is the total area of the pond and the walkway, in square feet
Answer:
Area = 324 ft²
Step-by-step explanation:
Given
Length = 15ft
Walkway = 3ft
Required
Determine the area of the pond + the walkway
To calculate the required area, we need to get the total length of a side .
This is calculated by adding the length of a side of the pond and the side of the walkway
Total Length = Pond Length + Walkway
Total Length = 15ft + 3ft
Total Length = 18ft
Now, the required area can be calculated as thus:
Area = Total Length * Total Length
Area = 18ft * 18ft
Area = 324 ft²
