Using the Algebraic tile method we get x=2 solution for equation model
What is Algebraic Tile method?The algebra tile method is a method of solving equations by using visual models, such as tiles with different values on them, to represent the unknowns and constants in the equation. It is often used to help students understand the process of solving equations and to see how the operations of addition and subtraction correspond to the process of combining or separating algebraic expressions.
In the question, we have 3 kinds of tile
X tilesunit positive tilesunit negative tilesEquation will be :

The sample proportion of Americans who are dissatisfied with education in kindergarten through grade 12 is 0.55 with sample of size 1000. We are interested in testing at the 5% significance level, if this sample provides evidence that the proportion of Americans who are dissatisfied with education in kindergarten through grade 12 differs significantly from 50%.
Required:
What is the p-value?
Answer:
p-value = 0,000755
We reject H₀. We can support that Americans who are dissatisfied with education in kindergarten throug grade 12 differs significantly from 50%
Step-by-step explanation:
Sample proportion : p₁ = 0,55
Sample size n = 1000
q₁ = 1 - p₁ q₁ = 1 - 0,55 q₁ = 0,45
Hypothesis Test:
Null Hypothesis H₀ p₁ = 0,5 ( 50 % )
Alternative Hypothesis Hₐ p₁ ≠ 0,5
Alternative hypothesis indicates that we have to develop a two-tail test
as n = 1000
p₁*n = 0,55 * 1000 = 550 q₁*n = 0,45*1000 = 450
Both products are bigger than 5. We can use the approximation of binomial distribution to normal distribution.
Significance level α = 5% α = 0,05 and α/2 = 0,025
z(s) = ( p₁ - 0,5 ) / √p₁*q₁/1000
z(s) = 0,05 * 31,62 / 0,4974
z(s) = 3,1785
From z-table we find p-value = 0,000755
Therefore p-value < 0,025
We are in the rejection region, we reject H₀
Pls help Whats the equation?
Answer: y = -5x + 6
Step-by-step explanation:
First, we need to find the slope, which would be m in the equation. To find m, we can use the formula called "rise over run". Here's the formula: [tex]m=\frac{y2-y1}{x2-x1}[/tex]
So, to use this formula, you pick two points from the line that you're given and solve for m.
Let's use the points (1,1) and (0,6). x1 would be 1, x2 would be 0, y1 would be 1, y2 would be 6
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{6-1}{0-1}[/tex]
[tex]m=\frac{5}{-1}[/tex]
[tex]m=-5[/tex] So, the slope is -5
Then, we need to find the y intercept, which would be b in the formula.
We can see that the point where the line meets the y axis is at (0.6), so the y intercept would be 6.
Now let's put everything together:
y = mx+b
y = -5x + 6

A student is graduating from college in 12 months but will need a loan in the amount of $10,958 for the last two semester. The student may receive either an unsubsidized Stafford Loan or a PLUS Loan. The terms of each loan are:
Unsubsidized Stafford Loan: annual interest rate of 3.85%, compounded monthly, and a grace period of six months from time of graduation
PLUS loan: annual interest rate of 4.15%, compounded monthly, with a balance of $11,421.51 at the time of repayment
Which loan will have a higher balance, and by how much at the time of repayment?
Answer:
To determine which loan will have a higher balance at the time of repayment, we need to calculate the balance of each loan after the interest has been compounded over the repayment period.
The unsubsidized Stafford Loan has an annual interest rate of 3.85% and a grace period of six months from the time of graduation. This means that the loan will accrue interest for a total of 12 months - 6 months = 6 months.
The balance of the unsubsidized Stafford Loan at the time of repayment can be calculated using the following formula:
Balance = Principal * (1 + Interest rate / Number of compounding periods per year)^(Number of compounding periods)
Plugging in the given values, we have:
Balance = $10,958 * (1 + 0.0385 / 12)^(6) = $10,958 * (1.003125)^(6) = $11,283.16
The PLUS loan has an annual interest rate of 4.15% and a balance of $11,421.51 at the time of repayment.
The balance of the PLUS loan at the time of repayment can be calculated using the same formula:
Balance = $11,421.51 * (1 + 0.0415 / 12)^(6) = $11,421.51 * (1.003479)^(6) = $11,973.54
Therefore, the PLUS loan will have a higher balance at the time of repayment, by $11,973.54 - $11,283.16 = $690.38.

The data reflects the amount of time spent on homework (x), paired with a corresponding test grade (y).
How can the y-intercept of the line be interpreted?
The minimum time spent on homework is approximately 72 hours.
The average time spent on homework is approximately 7.9 hours.
If no time is spent on homework, the test grade is approximately 72.
If no time is spent on homework, the test grade is approximately 7.9.
Answer:
If no time is spent on homework, the test grade is approximately 72.
Step-by-step explanation:
The y-intercept of the line can be interpreted if no time is spent on homework, the test grade is approximately 72.
What is the y intercept?
A graph can be described as a pictorial representation of data. A graph is made up of a x-axis and a y-axis. The y-intercept is the point where the line crosses the y-axis. The y-intercept is the value of the data set when x is zero.
If x is zero, y = 0 + 72

Step-by-step explanation:
31 - 27 = 4 31 + 27 = 58 therefore x = 27 and y = 31 Hope that helps!
Age of Sarah is 31 and age of Deborah is 27.
What is proportionality?If every pair of data values is related in the same way, by multiplying by a factor, then the relationship is proportional. A proportionate relationship can be identified by looking at data, an equation, or a graph.
Given, Deborah is x years old and Sarah is y years old. The sum of their ages is 58. If Deborah is 4 years young then Sarah is. Hence,
Deborah's age + Sarah's age = 48
x + y = 48
Also given, Sarah's age = Debora's age + 4
y = x +4
comparing both equations.
x = 27 and y = 31
Therefore, the age of Deborah is 27, and age of Sarah is 31.

Estimate a 15% tip on a dinner bill of $49.35 by first rounding the bill amount to the nearest ten dollars.
9514 1404 393
Answer:
$7.50
Step-by-step explanation:
Rounded to the nearest $10, the $49.35 bill becomes $50.
We can find 10% of that amount by moving the decimal point to the left. 10% of $50 is $5.00.
Then 5% of $50 is half of 10%, so is $5/2 = $2.50.
The estimated tip of 15% is the sum of 10% and 5% of the bill, so is ...
15%($50) = 10%($50) +5%($50) = $5.00 +2.50 = $7.50
The estimated 15% tip is $7.50.

What is percentage?
A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.
