The value of the variable x in the isosceles trapezoid is 14.
What is an isosceles trapezoid?An isosceles trapezium is a trapezium with equally sized non-parallel sides. In other words, the legs are equal in length and the bases are parallel.
Calculation of the value of the variable:
Since the measure of one angle should be 38 degrees
And, there is the equation 2x + 10 degrees
So for determining the value of x here we have to equate the equation
Since Angles are equal in an isosceles trapezoid
So,
2x + 10 = 38
2x = 38 - 10
2x = 28
x = 14
Therefore, The value of the variable in the isosceles trapezoid is 14.

 twice the difference of a number and seven is at most -29
This statement can be represented mathematically as: 2(x - 7) ≤ -29. The solution to the inequality is x ≤ -8 means x is less than or equal to -8.
Here, x is the number we are trying to find and "2(x - 7)" represents "twice the difference of a number and seven."
To solve for x, we can start by expanding the expression inside the parentheses:
2(x - 7) = 2x - 14
Now, we can substitute the expression for 2(x - 7) into the inequality:
2x - 14 ≤ -29
Next, we can isolate x by adding 14 to both sides of the inequality:
2x ≤ -15
Finally, we can divide both sides by 2 to obtain:
x ≤ -8
So, the solution to the inequality is "x is less than or equal to -8". This means that any number that is less than or equal to -8 satisfies the inequality.

As per unitary method the recipe makes 20.5 servings of lemonade.
The unitary method is a method used to find the number of servings in a recipe by dividing the total amount of ingredients by the serving size.
Let's say a serving size of lemonade is 1 cup. To find the number of servings, we need to divide the total amount of lemonade by the serving size.
In this case, the total amount of lemonade is
=> 2 cups of lemon juice + 16 cups of water + 2.5 cups of agave nectar
=> 20.5 cups.
So, the number of servings can be found by dividing 20.5 cups by 1 cup per serving, which equals 20.5.

For the three random tosses, there are only 4 potential values out of 8 possible combinations.
The sample space for W is thus:

There are 14,400 ways to select 5 working days in January without working on more than one Sunday.
Let the 5 working days be denoted by x1, x2, x3, x4, x5
Since there are 5 Sundays in the month of January, we need to select 5 days out of 26 days, such that none of them are Sundays. Therefore, the total number of ways to select 5 days out of 26 days without selecting any Sunday is 26C5.
This can be represented mathematically as:
26C5 = 26! / (5! x (26-5)!)
= 26! / (5! x 21!)

How is probability used in inferential statistics?
Inferential statistics employs probability to produce population forecasts based on a sample of data. Inferential statistics is a branch of statistics that makes conclusions or predictions about a population using sample data.
What is probability?In inferential statistics, probability is used to calculate the likelihood of a specific event or result based on sample data. For example, the sample data may be used to compute the likelihood that a given mean value is larger than a given value or that a certain fraction of the population has a given viewpoint. Furthermore, probability is utilized to calculate the amount of confidence associated with the inferences drawn from the sample data. Confidence levels are presented as percentages and show how certain the sample estimate is of the underlying population parameter. Thus, probability is important in inferential statistics because it allows us to generate population predictions based on sample data and determines confidence levels.

The approximately 99.38% of the data falls between the values 120 and 280.
To find the percentage of data that falls between the values 120 and 280, we need to find the standard scores (z-scores) that correspond to these values and use a standard normal table to find the proportion of data within this range.
First, we'll find the z-score for 120:
z = (120 - 200) / 40 = -2.5
Similarly, the z-score for 280 is:
z = (280 - 200) / 40 = 2.5
