5. The manufacturer of a spot remover claims that his product removes 90 percent of all spots. In a random sample, the spot remover removes 11 of 16 stains. Write the null and alternative hypotheses.

A bar graph would be the best type of graph to show the number of books each sixth-grade student read last year. Each student's reading data can be represented by a separate bar, making it easy to compare the number of books read by different students. The x-axis would list the students' names or assigned numbers, while the y-axis would represent the number of books read. Bar graphs are effective for displaying and comparing discrete data sets, making them ideal for this scenario.

A correlation coefficient represents the strength and direction of a linear relationship between two variables. A correlation coefficient close to zero indicates a weak relationship between the variables, where changes in one variable do not consistently predict changes in the other. However, it is important to note that a correlation coefficient of zero does not necessarily mean there is no relationship between the variables, as non-linear relationships may exist.

If you have an odd amount of numbers than there is no problem but say if you had 8 numbers you take the 4th and 5th numbers and find the average of the two. here is an example 1,3,4,5,7,9,11,14 you average 5 and 7,the 4th and 5th numbers, so the average is 6.hope this helped :) <3 :)

Oh, dude, a mystery line plot is like when you have this super mysterious line in a graph that just keeps everyone guessing. It's like a plot twist in a math problem, you know? It's all secretive and sneaky, just like that one friend who never tells you where they're going for lunch. So yeah, mystery line plot, it's the Sherlock Holmes of graphs.

Ah, the Pearson Coefficient of Skewness, fancy term for measuring the asymmetry of a probability distribution. It tells you if your data is skewed to the left, right, or if it's all hunky-dory symmetrical. Just plug in your numbers, crunch some math, and voila, you'll know how wonky your data is. Just remember, skewness doesn't lie, so embrace those skewed curves!

"Scratch a lie, find a thief" is an idiom that suggests that if you investigate or question someone's dishonesty or deceit, you are likely to uncover further wrongdoing or dishonest behavior. The act of scratching at the surface of a lie reveals the truth hidden beneath, just as uncovering a thief's actions can lead to discovering additional criminal behavior. Essentially, this phrase implies that deceit often leads to further deception or misconduct being exposed.

If you count 0000 to 9999 you have 10,000. For whole numbers you have 9999.

Not sure about "whole" numbers. There are 10,000 in all, of which 9000 (from 1000 to 9999) do not have leading 0s.

Oh, dude, it's like this: research is when you dig deep into a topic, like a detective trying to solve a mystery, while a survey is basically just asking a bunch of people what they think. So, research is like Sherlock Holmes, and surveys are more like a quick chat with your buddies to see where everyone wants to grab dinner. Both can give you info, but they're definitely not the same vibe.

To calculate the number of 4-digit combinations you can get from the numbers 1, 2, 2, and 6, we need to consider that the number 2 is repeated. Therefore, the total number of combinations is calculated using the formula for permutations of a multiset, which is 4! / (2!1!1!) = 12. So, there are 12 unique 4-digit combinations that can be formed from the numbers 1, 2, 2, and 6.

1 followed by 30 zeroes would be a nonillion in US usage and a quintillion in Continental European and traditional British usage.

Traditional British usage if by that you mean something that was abandoned around 50 year ago!

To round off 790 to the nearest thousand, we need to look at the hundreds place, which is 9 in this case. Since 9 is greater than or equal to 5, we will add 1 to the thousands place, making it 1. Therefore, when rounded to the nearest thousand, 790 becomes 1000.

in multi-stage sampling the population is divided into a nonumber of units & in multi-phase sapling when certain items of information are collected from all the units in a sample and other itemsof usually more detailed information are collected from the subsample of the units composing the original sample.

The four numbers that can be used in combinations or differences to make all numbers from 1 to 30 are 1, 2, 4, and 8. These numbers are powers of 2, which allows for the creation of all numbers from 1 to 30 through various combinations and differences. By using these four numbers strategically, one can generate any integer between 1 and 30.

A sample of matter that has more than one set of properties is called a mixture. A mixture is a combination of two or more substances that are physically combined but not chemically bonded. Each component of a mixture retains its individual properties, allowing for the observation of multiple sets of properties within the same sample.

1/6 of all outcomes should be a 5.

300*1/6=50

This is the answer regardless of what you are rolling for. You would find whatever number you want and average about 50 times if you were to roll the dice 300 times. You might not get exactly 50, but it won't be far from that. There are faces on a die, and the odds of any one of those 6 numbers showing up is 1 out of 6 times.

The above is only true if the dice are not rigged in any way ("loaded dice"). Now, if only one number likes to keep coming up, you might be dealing with loaded dice. In that case, the dice are made for cheating and the mathematical laws of average no longer apply.

When you are considering a course of action, it is often useful to try to figure out not only what the results will be, but what are the range of possible results, because we seldom are completely certain about the results of any given action. For example, I am considering going to see a particular movie. This would have a number of possible outcomes. I might enjoy the movie, I might not enjoy the movie, the theater could catch fire (or suffer some other disaster) which could prevent me from being able to see the entire movie, I might fall asleep during the movie, I might suffer a heart attack while watching the movie, and so forth. I can then try to decide how likely each of these possibilities are, and on that basis, I can try to evaluate whether it is a good idea for me to go to see the movie. That is called weighing possible outcomes. Metaphorically speaking, a more likely outcome is heavier, when you are weighing outcomes.

To determine the number of combinations of 3 words, we need to know the total number of words available. Let's say we have a pool of n words. The formula to calculate the number of combinations of 3 words without repetition is n! / (3!(n-3)!), where "!" denotes factorial. This formula accounts for the number of ways we can select 3 words from a pool of n without repetition.

"Metza metza" is a Greek phrase that translates to "half and half" in English. It is commonly used to describe something that is divided equally or in half portions. This phrase can be used in various contexts, such as sharing food, splitting costs, or describing a mixture of two different things in equal parts.

Value of 1 is 1

Value of 6 is 6/10

Value of 3 is 3/100

Value of 9 is 9/1000

Oh, dude, you're really testing my math skills here. Okay, so one mile is equal to 5,280 feet, and a typical city block is around 330 feet, so if we do the math, that's like 16 city blocks in a mile. But hey, who's counting, right?

Largest 4 digit number = 9999 Smallest 3 digit number = 111 9999 - 111 = 9888 Largest 4 digit number = 9999 Smallest 3 digit number = 111 9999 - 111 = 9888
