After selecting 25 students randomly, they find that 9th graders watch the most television per dayPart A: What is the population?
Part B: What is the sample of the population?
Part C: Discuss collaboratively: Explain the difference between population and sample
Answers
Sample is the small number that represents the population. It is represented by 25 students.
Population is the whole number, sample is part of the whole number.

Darryl currently owes $1,431.72. Let's solve his minimum payment.
=> 1,431.72 * 0.0251 = 35.94 dollars
=> 1,431.72 + 35.94 dollars = 1467.656172 or 1467.7 dollars.
Answer:
$35.94.
Step-by-step explanation:
We have been given that Darryl’s credit card has a minimum monthly payment of 2.51% of the card’s balance. Darryl currently owes $1,431.72.
To find the minimum payment we will have to calculate 2.51% of $1431.72.
Upon rounding our answer to nearest cent we will get,
Therefore, the minimum monthly payment to the nearest cent will be approximately $35.94.

The solution to the system of equations is x = 2 and y = 4.
To solve the system of equations:
y = 6x - 8 ...(Equation 1)
y = -3x + 10 ...(Equation 2)
We can set the two equations equal to each other:
6x - 8 = -3x + 10
To solve for x,
6x + 3x = 10 + 8
9x = 18
Dividing both sides by 9:
x = 18/9
x = 2
So, y = 6(2) - 8
y = 12 - 8
y = 4
Therefore, the solution to the system of equations is x = 2 and y = 4.

Answer:
x = 2
Step-by-step explanation:
hey there,
< If these two are together, then the problem would look like this:
From the first equation, we can see that y = 6x-8. I am assuming in your problem you need to find what "x" is equal to, so plug in the first "y" value into the second one.
6x - 8 = -3x + 10
Bring all "x"s to one side and regular numbers to the other side.
6x + 3x = 10 + 8
9x = 18
x = 2
x = 2 is your final answer. >

Answer: x^2 + 23x + 49
Step-by-step explanation:
The area of the shaded region is the area of the big rectangle minus the square
area of rectangle
area = bh
b = 2x + 5
h = x + 10
area = (2x+5)(x+10) FOIL
= 2x^2 + 20x + 5x + 50
= 2x^2 + 25x + 50
area of square
area = s * s
s = x + 1
area = (x+1)(x+1) FOIL
= x^2 + x + x + 1
= x^2 + 2x + 1
area of shaded region
now subtract rectangle - square
(2x^2 + 25x + 50) - (x^2 + 2x + 1)
= 2x^2 + 25x + 50 - x^2 - 2x - 1 combine like terms
= x^2 + 23x + 49
Answer:
(x² + 23x + 49) units²
Step-by-step explanation:
(x + 10)(2x + 5) - (x + 1)²
(2x² + 20x + 5x + 50) - (x² + 2x + 1)
2x² + 25x + 50 - x² - 2x - 1
x² + 23x + 49
True
