When comparing the data, a measure of variability which should be used for both sets of data to determine the location with the most consistent temperature is: C. Range, because Sunny Town is skewed.
What is skewness?In Mathematics, skewness can be defined as a measure of the asymmetry of a box plot (box-and-whisker plot) or histogram and as such, a box plot (box-and-whisker plot) or histogram has a normal distribution when it is symmetrical.
By critically observing the box plot (box-and-whisker plot) which represent Sunny Town, we can logically deduce that it is skewed.
On the other hand (conversely), the box plot (box-and-whisker plot) for Desert Landing is symmetrical (vertical line dividing the box into two equal halves), which simply means that both whiskers on either sides of the box plot (box-and-whisker plot) are relatively equal and symmetric.

Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.
L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)
To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).

The pattern associated with the scatter plot is given as follows:
There is a positive linear association.
What is scatter plot?A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.
Here, we have,
The scatter plot shows a series of points in (input, output) format, in which the input is the time studying in minutes and the output is the grade.
As the increasing graph shows, the more a person studies, the better the grade, hence there is a positive relationship among the variables.
The increase is slow initially while it has a higher rate for a higher number of minutes, hence the association is also nonlinear.
As the X value increases, so does the Y value which means the positive association.
Also, it is in a straight line, which means it is a linear association.
Which would make it a positive linear association.

The table below shows the change in price of a particular share on the stock market.
Daily share price changes
Day Daily change (In dollars)
1 +2.75
2 -4.375
3 +0.875
4 -2.5
Part A: By how did the price of the share change from the start of day 1 to the end of day 4?
Part B: At the end of day 4 the price of the share is $102.85. What was the price of the share at the start of day 1?
Answer:
Part-a: The price of the share decreased by $3.25 from the start of day 1 to the end of day 4.
Part-b: The price of the share at the start of day 1 was $106.10.
Step-by-step explanation:
Part A: To calculate the change in price from the start of day 1 to the end of day 4, we need to add up all the daily changes. The daily changes given are:
Day 1: +2.75
Day 2: -4.375
Day 3: +0.875
Day 4: -2.5
Adding these values together:
Change = 2.75 - 4.375 + 0.875 - 2.5 = -3.25
The price of the share decreased by $3.25 from the start of day 1 to the end of day 4.
Part B: To find the price of the share at the start of day 1, we need to subtract the total change from the given price at the end of day 4.
Price at the end of day 4 = $102.85
Total change = -3.25
Price at the start of day 1 = Price at the end of day 4 - Total change
= $102.85 - (-3.25)
= $102.85 + 3.25
= $106.10
Therefore, the price of the share at the start of day 1 was $106.10.

What is 0.65 expressed as a fraction in simplest form?
What is 2.¯5 expressed as a fraction in simplest form?
What is 1.0¯24 expressed as a fraction in simplest form?
Answer:
Part A)
Part B)
Part C)
Answer:
Step 1: Write down the decimal as a fraction with the decimal number as the numerator and 1 as the denominator.
Step 2: Multiply both the numerator and denominator by 10^n, where n is the number of digits after the decimal point.
Step 3: Simplify the resulting fraction.
Using these steps, we can convert the given decimal numbers to fractions:
0.65
Step 1: 0.65 = 65/100
Step 2: Multiply numerator and denominator by 10 to get rid of the decimal point: 65/100 = 650/1000
Step 3: Simplify by dividing numerator and denominator by their greatest common factor of 50: 650/1000 = 13/20
Therefore, 0.65 expressed as a fraction in simplest form is 13/20.
2.¯5
To handle repeating decimal numbers, we can use the following method:
Step 1: Let x be the repeating decimal number.
Step 2: Multiply both sides of x by 10^n, where n is the number of digits in the repeating part of the decimal number.
Step 3: Subtract the original number from the number obtained in step 2 to eliminate the repeating part.
Step 4: Solve for x by dividing both sides of the equation obtained in step 3 by an appropriate factor.
Step 1: Let x = 2.¯5
Step 2: Multiply both sides by 10: 10x = 25.¯5
Step 3: Subtract the original equation from step 1: 10x - x = 25.¯5 - 2.¯5
Simplifying: 9x = 23
Step 4: Solve for x by dividing both sides by 9: x = 23/9
Therefore, 2.¯5 expressed as a fraction in simplest form is 23/9.
1.0¯24
Step 1: Let x = 1.0¯24
Step 2: Multiply both sides by 10^2 to eliminate the repeating part: 100x = 124.¯24
Step 3: Subtract the original equation from step 1: 100x - x = 124.¯24 - 1.0¯24
Simplifying: 99x = 123
Step 4: Solve for x by dividing both sides by 99: x = 123/99
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor of 3: 123/99 = 41/33.
Therefore, 1.0¯24 expressed as a fraction in simplest form is 41/33.
Step-by-step explanation:
0.65 expressed as a fraction in simplest form is 13/20.
2.5 expressed as a fraction in simplest form is 5/2.
1.024 expressed as a fraction in simplest form is 256/250.
What is the simplified form of the expressions in fraction?0.65 expressed as a fraction in simplest form:
Write the decimal as a fraction by placing it over 1. In this case, 0.65 becomes 0.65/1.
Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.
In this case, multiplying by 100 will do the trick, so we get (0.65 × 100)/(1 × 100) = 65/100.
Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 65 and 100 is 5, so dividing both by 5 yields 13/20.
2.5 expressed as a fraction in simplest form:
Write the decimal as a fraction by placing it over 1. In this case, 2.5 becomes 2.5/1.
Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.
In this case, multiplying by 10 will do the trick, so we get (2.5 × 10)/(1 × 10) = 25/10.
Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 25 and 10 is 5, so dividing both by 5 yields 5/2.
1.024 expressed as a fraction in simplest form:
Write the decimal as a fraction by placing it over 1. In this case, 1.024 becomes 1.024/1.
Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.
In this case, multiplying by 1000 will do the trick, so we get (1.024 × 1000)/(1 × 1000) = 1024/1000.
Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 1024 and 1000 is 8, so dividing both by 8 yields 128/125.
