Each day at lunchtime, at leat 53 people buy food from a food truck. Uing the variable p
, an inequality that repreent that ituation i
An inequality that repreent is inequality is p≥ 53
Given that, at least 53 people buy food from the food truck. It means minimum 53 people buy the food, and number greater than 53 is quite possible; however, the possibility of people buying food less than 53 is not possible.
Since the number of people is alway 53 or greater than 53 therefore we may represent this condition using the greater and equal sign.
Lets use the variable p for people who buy the food.
Now the inequality can be written as
p≥ 53
About ProbabilityProbability is the part of mathematics that discusses the size of the likelihood of something happening in life. Indeed, there are many events that cannot be ascertained to occur or not occur at a later time. but by knowing the measure of the success or failure of the expected event to occur, people can make better and wiser decisions about what should be done. Probability theory provides methods related to uncertainty and is an integral part of the decision-making process.
The concepts of probability are the basis of samples and the inferences about the population that can be made from a sample. After understanding the concept of probability which is the basis of statistics, we will then be given the theory of random variables and their properties, formation of probability distributions, socialization of various discrete and constant random variable probability distributions, and statistical sampling distributions.

What is the simplified form of this expression? 16yx÷4+6yx(−2)
Answer:
The correct answer is -8yx.
Step-by-step explanation:
To simplify the expression 16yx÷4 + 6yx(-2), we can use the following steps:
Start by computing the expression within the parentheses:
6yx(-2) = -12yx.
Next, divide 16yx by 4 to get 4yx.
Finally, add the two simplified expressions from steps 1 and 2:
4yx + (-12yx) = -8yx.
Hence, the simplified form of the expression 16yx÷4 + 6yx(-2) is -8yx.

how many ways are there to split a dozen people into 3 teams, where each team has 4 people?
By using permutations and combinations, We can arrange 12 people into 3 teams of 4 in 5775 different ways.
Here, we will use the concept of permutations and combinations to solve the question.
We have to arrange 12 people into 3 teams of 4.
We know that ⁿCr = n! / [(n - r)! × r!]
No. of ways to select the first 4 people in the first group = ¹²C₄
= 12! / [(12 - 4)! × 4!]
= 12! / [(8! × 4!)]
= 495
No. of ways to select 4 people from the remaining 8 for the second group = ⁸C₄ = 8! / [(8 - 4)! × 4!] = 8! / [(4! × 4!)] = 70
No. of ways to select 4 people from 4 for the third group = ⁴C₄ = 4! / [(4 - 4)!] × 4!] = 4! / [(0! ×4!)] = 1
Total no. of ways to select people for group = (495 x 70 x 1) / 3! = 34650 /6 = 5775
Hence, we can split 12 people into 3 teams of 4 in 5775 different ways.

Mark has a certain amount budgeted for dining out each month. Last month, the difference between the amount he budgeted and the amount he actually spent on dining out was less than -20 dollars.
Answer: This means that Mark spent more on dining out last month than what he had budgeted, and the difference was greater than 20 dollars.
Mark had set aside a specific amount of money each month for dining out expenses. However, last month he exceeded that amount and spent more than what he had budgeted. The difference between the amount he planned to spend and what he actually spent was negative and greater than 20 dollars, indicating that he overspent by more than 20 dollars. This implies that the cost of dining out was higher than expected, and Mark spent more money on it than he had originally intended to.

If Wendell were to slice the doghouse with a plane parallel to the two sides through any section of the doghouse, what shape would the slice be?
The slice would be in the form of a pentagon.
What is meant by parallel lines?Parallel lines in geometry are coplanar infinite straight lines that don't intersect anywhere. When two planes in the same three-dimensional space are parallel, they never cross. Curves that maintain a set minimum distance from one another and do not touch or intersect are said to be parallel curves.
Parallel lines are those in a plane that are regularly spaced apart from one another. There is no crossing of parallel lines.
Wendell would need to make a parallel cut to the bases of the pentagons in order to split the doghouse in two.
Consequently, the section will be pentagonal in shape.
Consequently, the slice is pentagonal.

The tertiary alkene (c) is the most stable, followed by the secondary alkene (a), and finally the primary alkene (b).
The stability of alkenes depends on the number of alkyl substituents attached to the double bond, as well as their positions. Alkenes with the most stable arrangement have the greatest number of alkyl substituents attached to the double bond and are known as tertiary alkenes. Secondary alkenes have two alkyl substituents attached to the double bond and primary alkenes have only one alkyl substituent attached to the double bond.
Based on this information, the order of decreasing stability of alkenes is:

C. Nonsampling error is the error that results from factors outside of the sampling process, such as undercoverage, nonresponse bias, response bias, or data entry errors. Sampling error is the error that results because a sample is being used to estimate information about a population.
Nonsampling error describes problems in data collecting and processing that take place unrelated to the sampling procedure itself. It is brought on by things like inaccurate data collection or measurement, interviewer bias, response bias, undercoverage, or data entry mistakes. Whether a sample or a whole census is employed, nonsampling mistakes can still happen.
On the other hand, sampling error is the error that happens when a sample is used to estimate the characteristics of a population. There will always be some degree of uncertainty when drawing conclusions about the population from sample data because the sample is only a part of the whole population. Sampling error develops as a result of the random variation present during the selection of a sample.

To find out how much candy Vanessa should eat each day, we first need to find the total amount of candy in the box. If the box weighs 1/8 of a pound, we can convert this weight to ounces to get a clearer idea of the quantity of candy. There are 16 ounces in a pound, so 1/8 of a pound is equal to 1/8 * 16 = 2 ounces.
Now that we know the total amount of candy, we can divide this by the number of days that Vanessa wants the candy to last to find out how much she should eat each day. If the candy is meant to last 2 days, she should eat 2 ounces / 2 days = 1 ounce of candy per day.

The equation for the total cost, y, in terms of the number of kites purchased, x, is y = 4x + 8.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that, there is a charge of $4 per kite plus a flat rate of $8 to ship these items to Alaska.
Let x be the number of kites purchased.
Cost for the kites purchased = 4x
Total cost including the shipping charge = 4x + 8
When x = 0, y = $8
When x = 1, y = 4 + 8 = 12
When x = 4, y = 16 + 8 = 24
When x = 7, y = 28 + 8 = 36
When x = 10, y = 40 + 8 = 48

Using the formula f (n) = 35 - 5n, starting with n = 1. Find the 5th term in the sequence.
For the given the formula f (n) = 35 - 5n, the 5th term of the sequence is f(5) = 10.
A sequences is an ordered sets of integers (usually called ad "terms"), such as 1, 5, 9. Some sequences follow a specific pattern that can be exploited to indefinitely expand them. For example, 4, 9, 14 follows the pattern "add 5," and we can now proceed with the sequence. Formulas that tell us how to discover any term in a series can be found in sequences.
The formula of the sequence in this case is:
f(n) = 35 - 5n.
Then
n = 1 --> f(1) = 35 - 5(1) = 30
The 5th term means we substitute n = 5 into the formula.

2.9 ^ (x + 10) = 89
Next, we'll take the logarithm base 2.9 of both sides:
log2.9 (2.9 ^ (x + 10)) = log2.9 89
x + 10 = log2.9 89
Finally, we'll solve for x:
