Answer:
One inference that can be made is that the age group of 12-19 consume more sodas than the age group of 20-39.
Step-by-step explanation: ok sooooo
The required individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19.
What is mathematical reasoning?Mathematical reasoning is the process of using logical thinking and mathematical concepts to solve problems, prove theorems, and develop mathematical models. It involves identifying patterns, making conjectures, and using deductive reasoning to arrive at logical conclusions based on given assumptions.
Based on the information given in the table, it can be inferred that individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19. This inference can be made because the mean and median values of the second sample (aged 20-39) are higher than those of the first sample (aged 12-19). Specifically, the mean for the second sample is 8.6 cans of soda per week, while the mean for the first sample is 6.96 cans of soda per week. Similarly, the median for the second sample is 8 cans of soda per week, while the median for the first sample is 5 cans of soda per week.

Use polynomial identities to factor 64 + 27a^3
Answer:
(3a+4)(9a^2-12a+16)
Step-by-step explanation:
It's a perfect square :)
The factors of the given polynomial are (4+3a)(9a²-12a+16)
What is polynomial?A polynomial is defined as an expression which is composed of variables, constants and exponents, that are combined using mathematical operations.
Given that, a polynomial, 64+27a³
Using identity : a³+b³ = (a+b)(a²-ab+b²)
We get,
= (4+3b)(4²-4x3a+(3a)²)
= (4+3a)(16-12a+9a²)
Hence, the factors of the given polynomial are (4+3a)(9a²-12a+16)

A charity organization had to sell a few tickets to their fundraiser just to cover necessary production costs after selling 10 tickets, they were still a net loss of $800 (due to the product cost). They sold each ticket for $70 let y represent the net profit (in dollars) when they have sold x tickets
Answer:
y = 70x - 1500
Step-by-step explanation:
Price per ticket = 70
Using the relation :
y = mx + c
x = number of tickets sold
When x = 10 ; y = - 800
Hence,
-800 = 70(10) + c
-800 = 700 + c
-800 - 700 = c
Hence, c = - 1500
The equation for the net profit in dollars is :
y = 70x - 1500

Represent the blanks with x
Option A:
[tex]x : 4 = 12 : 16[/tex]
Convert to fractions
[tex]\frac{x}{4} = \frac{12}{16}[/tex]
Multiply through by 4
[tex]4 * \frac{x}{4} = 4 * \frac{12}{16}[/tex]
[tex]x = \frac{48}{16}[/tex]
[tex]x = 3[/tex]
Option B:
[tex]1 : 5= x : 15[/tex]
Convert to fraction;
[tex]\frac{1}{5} = \frac{x}{15}[/tex]
Multiply through by 15
[tex]15 * \frac{1}{5} = \frac{x}{15} * 15[/tex]
[tex]15 * \frac{1}{5} = x[/tex]
[tex]3 = x[/tex]
[tex]x = 3[/tex]
Option C:
[tex]x : 1 = 12 : 3[/tex]
Convert to fraction
[tex]\frac{x}{1} = \frac{12}{3}[/tex]
[tex]x = 4[/tex]
Option D
[tex]15:x = 3:1[/tex]
Convert to fraction
[tex]\frac{15}{x} = \frac{3}{1}[/tex]
Cross Multiply
[tex]3 * x = 15 * 1[/tex]
[tex]3 * x = 15[/tex]
Divide through by 3

Answer:
x = 20
Step-by-step explanation:
For the lines to be parallel, then (3x + 20) and (3x) are alternate angles and congruent, thus
3x = 2x + 20 ( subtract 2x from both sides )
x = 20
