The perimeter of given square is 4(s + 3)
Given that:
One side of square has length = (s+3)
A square is a geometric figure having 4 equal straight sides and all internal angles are of 90 degrees.
Perimeter of a closed figure is a measure of length of all the lines needed to construct that figure.
Perimeter of square of side a is thus a + a + a + a = 4a.
Here given is a = (s+3)
Thus perimeter of given square with side (s+3) is 4(s+3).

In the diagram ,M//N . Identify all of the angles that are congruent to 2
Answer:
Angles 4, 6 and 8.
Step-by-step explanation:
Let α and β be two angles, these will be congruent angles if they have exactly the same measure, that is, α = β.
A line that cuts two parallels forms congruent angles.
When two intercept lines form 4 angles. Those that are opposite to each other are vertical angles, these are always congruent.
In the diagram you can see that the angles congruent to 2 are: 4, 6 and 8.
Angle 4 is opposite to the angle 2, therefore it is congruent.
Angle 6 has the same measure of angle 2 because the lines m and n are parallel.
Angle 8 is opposite angle 6, so it is congruent to angle 2 which is equal to angle.

the local Swim Center is making a special offer they regular charge is $7 per day to swim at the pool the special offer would have swimmers pee in their room and fee of $30 and then a daily pass will only be $4 a day
The regular and fixed charges are shown by forming the equation and shown in the table.
What is a linear equation?A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.
It can be represented as a straight line on a graph.
Suppose the number of days be x.
Then, as per the question the cost as per the regular charge is $7x.
And, for the offer it is given as $30 + 4x.
Now, the cost for both charges can be calculated for 10 consecutive days as below,
Regular Charge :
For x = 1, 7 × 1 = $7
The table for the given case can be shown as below,
Number of Days Regular Charge Offer Charge
1 $7 30 + 4 × 1 = $34
2 7 × 2 = $14 30 + 4 × 2 = $38
3 7 × 3 = $21 30 + 4 × 3 = $42
4 7 × 4 = $28 30 + 4 × 4 = $46
5 7 × 5 = $35 30 + 4 × 5 = $50
6 7 × 6 = $42 30 + 4 × 5 = $54
7 7 × 7 = $49 30 + 4 × 5 = $58
8 7 × 8 = $56 30 + 4 × 5 = $62
9 7 × 9 = $63 30 + 4 × 5 = $66
10 7 × 10 =$70 30 + 4 × 5 = $70
Hence, the table for both the charges is formed.

Katrin’s monthly payment for electricity went down from £38.60 to £34.20 she thinks this means that her monthly payment has gone by 1/6. Is katrin correct? Show how you think this?
Katrin's claim about her monthly payment going down by 1/6 is incorrect.
Explanation:To determine if Katrin's monthly payment has gone down by 1/6, we need to compare the difference between her old monthly payment (£38.60) and new monthly payment (£34.20) with 1/6 of her old monthly payment. Taking 1/6 of £38.60, we get £6.43.
The actual difference between her old and new monthly payment is £38.60 - £34.20 = £4.40. This difference is not equal to £6.43, so Katrin's claim is incorrect.
Therefore, Katrin's monthly payment has not gone down by 1/6.

Which point would be considered an outlier?
(1, 5)
(3, 9)
(5, 4)
(9, 1)
Answer:
Step-by-step explanation:
Definition of an outlier:
A value that "lies outside" (is much smaller or larger than) most of the other values in a set of data.
Here in the scatter plot we can see that
(3,9) deviates from other values very much.
Outlier An extreme value in a set of data which is much higher or lower than the other numbers. Outliers are to be removed to get accurate results since they have the power to affect the mean value of the data but have little effect on the median or mode of a given set of data.
That is why when outliers are present mean or mode is the better mode to measure central tendency.
Which point is a reflection of point R (-2, 9) first across the y-axis and then across the x-axis?
A : (-9, -2)
B: (-2,-9,)
C: (2, -9)
D: (9, -2)
Final answer:
Explaining how to find the reflection of a point across the y-axis and then the x-axis that is option C is correct.
Explanation:
To find the reflection of point R(-2, 9) first across the y-axis and then across the x-axis, we apply the transformations for each axis separately. When reflecting across the y-axis, the x-coordinate changes sign, making it (-2, -9). Then, reflecting across the x-axis changes the sign of the y-coordinate, resulting in the final reflection at point (2, -9).

1 weekday $110
2 weekend $180
2 weekday $130
3 weekend $230
3 weekday $180
4 weekend $300
4 weekday $250
answers:
A) It is a function because there is a price given for every package.
B) It is a function because weekend packages are always $50 more than weekday packages.
C) It is not a function because each package number has two different prices.
D) It is not a function because there are two different packages available for $180.
Option: C is the correct answer.
C) It is not a function because each package number has two different prices.
Step-by-step explanation:Function--
Function is a mapping from a set A to set B such that each element of set A is mapped to a unique number.
i.e. every element has a single image.
Here a package number has two different rates or prices.
(Since let set A is package number and set B is a price of the package. )
As element of set A has more than one image.
Hence, it is not a function.

Catherine finds that in a randomly selected sample of 500 families in her home town, 45% own at least one computer. Her research shows that there are a total of 35,000 families in her town.
Which statements are true? Select EACH correct answer.
A If she collected data for a random sample of 1000 families in her home town, then that percentage would be a better estimate for the percentage of all 35,000 families that own a computer.
B Since her sample was randomly selected, she can reasonably infer that about 45% of the 35,000 families in her town own at least one computer.
C To estimate the percentage well, she would need to collect data for all 35,000 families.
D Since her sample was only 500 families, it is not possible that the percentage is a good estimate for the percentage of all 35,000 families that own a computer.
Statements A and B are true
Let's analyze each statement based on statistical principles:
A: This statement is true. Increasing the sample size to 1,000 families would yield a better estimate of the true proportion of families owning at least one computer. A larger sample size reduces the margin of error, making the estimate more precise.B: This statement is true. Since her sample was randomly selected, she can reasonably infer that about 45% of the 35,000 families in her town own at least one computer. Random sampling helps in representing the population accurately.C: This statement is false. Collecting data from all 35,000 families, though more accurate, is impractical and unnecessary. A well-conducted survey with a good sample size can provide a reliable estimate.D: This statement is false. Even though the sample size is 500 families, it can still provide a reasonable estimate for the percentage of families owning a computer if randomly selected.Conclusion
Statements A and B are correct, as they follow good statistical sampling practices. Statements C and D are not accurate in the context of the given scenario.

A car’s original price was $26,500. Mr. Thomas paid $21,730. What percent discount did Mr. Thomas receive on the car?
Final answer:
Mr. Thomas received an 18% discount on the car purchased for $21,730 from an original price of $26,500.
Explanation:
Mr. Thomas received a discount on the car he purchased, and we can calculate the percent discount using the original price and the sale price. The formula for percent discount is: Percent Discount = ((Original Price - Sale Price) / Original Price) × 100%. Applying this to the given numbers:
Original Price = $26,500
Sale Price = $21,730
The difference between the original price and the sale price is the discount amount:
Discount Amount = Original Price - Sale Price
Discount Amount = $26,500 - $21,730
Discount Amount = $4,770
Now we use the formula to calculate the percent discount:
Percent Discount = ($4,770 / $26,500) × 100%
Percent Discount = 18%
Therefore, Mr. Thomas received an 18% discount on the car.
