What are the hearing numbers in swertres pcso lotto for tomorrow?
I'm sorry, but as an AI language model, I don't have real-time information on specific lottery numbers or results. The hearing numbers for the Swertres PCSO lotto are typically based on various methods and strategies used by players to predict potential winning combinations. It's important to remember that lottery games are based on chance, and there is no guaranteed way to predict the winning numbers. I recommend checking the official PCSO website or contacting authorized lottery outlets for the most up-to-date information.
How many Friday's are in a year?
The number of Fridays in a year is the same as the number of weeks in a year = 52 not so fast my friend, occasionally you'll have 53. It depends on 365 or 366 divided by 7 = 52.14285714.. or 52.285714.. Which is 52 weeks and either 1 or 2 days. So, if the year STARTS on a Friday, then you'll have 53 in a 365 day type year, and if one of the first two days is a Friday on a leap year, then you'll also have 53 Fridays. So look at January 1st (or also 2nd in a leap year) and you'll know the answer. No Friday's, 52. If a Friday is there, then you'll have 53. Fun and Easy.

How many three digit numbers are multiples of 20?
To find how many three-digit numbers are multiples of 20, we need to determine the range of three-digit numbers divisible by 20. The smallest three-digit number divisible by 20 is 100, and the largest is 980. To find the count of numbers in this range, we can divide the largest number by 20 and subtract the result of dividing the smallest number by 20, then add 1 to account for the inclusive range. Therefore, the number of three-digit multiples of 20 is (980/20) - (100/20) + 1 = 49 - 5 + 1 = 45.
Black Friday (happens in America) is when everything goes on sale or in other words clearance which makes people wake op early to buy things on clearance.
It's about stores claiming to have really good sales. However, it is criticized for not having large quantities of the sale items. This event happens in most major stores the day right after thanksgiving.
Another view
Black Friday usually refers to the day after Thanksgiving, the official start of the holiday shopping season. Stores offer deep discounts and sell a few products at a loss in order to entice shoppers to spend.
"Black" derives from old accounting slang, "in the black," first used in 1926 (the term was first applied to holiday shopping in the late 60s or early 70s). When a business is operating at a loss, it is said to be "in the red," referring to the way negative numbers were recorded in accounting ledgers; when a business is making a profit, it is said to be "in the black," and the ledger shows positive numbers recorded in black ink. Black Friday is often the day retailers finally begin making a profit for the year, shifting their status from being "in the red" to being "in the black." In the retail industry, most of the profit is made during the five-week period between Black Friday and the end of the year.
The sales figures from Black Friday are compared to previous years and used as a barometer to predict how much shoppers will spend during the holiday season.
What are disadvantages of median?
One disadvantage of using the median is that it may not accurately represent the entire dataset if there are extreme outliers present, as the median is not influenced by the magnitude of these outliers. Additionally, the median may not be as intuitive to interpret as the mean for some individuals, as it does not provide a direct measure of the total value of the dataset. Finally, calculating the median can be more computationally intensive compared to other measures of central tendency, especially with large datasets.
Mode is 100 and mean is less than the median?
Oh, dude, it's like when you have a group of numbers and the mode, which is the most common one, is 100, but the mean, which is the average, is lower than the median, which is like the middle number when they're all lined up. So basically, it's just a funky little math situation where the numbers are playing musical chairs and the mean ends up being the odd one out below the median.
If there are 2 modes how do you find the right one?
Oh, dude, finding the right mode is like finding the right flavor of ice cream - you just gotta taste test them both! To find the mode in a set of data with 2 modes, you simply identify the values that appear most frequently. It's not rocket science, but hey, it's statistics - close enough, right?
What are the chances of rolling doubles 7 times in a row?
The probability of rolling doubles on a fair six-sided die is 1/6. To roll doubles 7 times in a row, you would need to multiply this probability by itself 7 times, resulting in (1/6)^7. This equals approximately 1 in 78,364,164,096, which means the chances of rolling doubles 7 times in a row are extremely low.
What do you call a person who studies plants?
Botany is the scientific study of plant life, so a person who undertakes this type of study is called a 'botanist'.

For a 24-hour clock, the only valid numbers are 0:00 to 5:55 - that's 6 times.
A 12-hour clock won't show 0:00 (it will show 12:00 instead), but it will show all the other combinations twice each - for a total of 10 per day.

How many three digits are positive integers there whose digits are 2 or 5?
8.
A way to work this out is figure out how many possible digits can go in each place value position (units, tens, hundreds) and multiply these together. Since there are 2 possible digits that can go in each position and there are three positions, you would go: 2 x 2 x 2 = 8

Shaking the sample before transferring it into a sterile McCartney bottle helps to ensure homogeneity of the sample, allowing for a representative portion to be transferred. This helps to minimize sampling errors and ensures accurate analysis of the sample. Additionally, shaking the sample helps to resuspend any settled particles or components, leading to a more uniform distribution in the McCartney bottle.
Well, darling, "Ixx" is just a placeholder used in engineering to represent a moment of inertia about the x-axis. It's basically a fancy way of saying how resistant an object is to changes in rotation around that particular axis. So, next time you hear "Ixx," just remember it's all about that rotational resistance, honey.
What weight is 600 gallons of water?
The weight of 600 gallons of water can be calculated by multiplying the volume (600 gallons) by the density of water. The density of water is approximately 8.34 pounds per gallon. Therefore, the weight of 600 gallons of water would be 600 gallons x 8.34 pounds/gallon = 5,004 pounds.
What is the largest whole numbers that round off to 5000 to the nearest thousand?
5499.
To round to the nearest thousand, the hundreds digit would be the decider: if 5 or more it would round up, 4 or less would round down. Need to round down, so the hundreds digit must be 4.
The tens and units make no difference, so have them as large are possible, namely 9 each, to give: 5499 as the largest whole number that rounds to 5000 to the nearest 1000.
A quick way is to observe 1000/2 = 500, so need to add 1 less than this (499) to the number and it will round down, that is 5000 + 1000/2 - 1 = 5000 + 500 - 1 = 5499.
What is the role of the stochastic error term in regression analysis?
Regression analysis is based on the assumption that the dependent variable is distributed according some function of the independent variables together with independent identically distributed random errors. If the error terms were not stochastic then some of the properties of the regression analysis are not valid.
What is the difference between a graph and a grid?
A graph is like a bar chart and a grid is like a table they are different ways of presenting information like you where recording a what a lesson was called you would put it in a grid because its a word and you cant record words in a graph because you would usually use numbers for a graph.
In a statistical model, variations in the dependent variable can be attributed to independent variables. However, there is a random element that is not accounted for and this is the stochastic error.
What is the difference between the stochastic error term and the residual?
the residual is the difference between the observed Y and the estimated regression line(Y), while the error term is the difference between the observed Y and the true regression equation (the expected value of Y). Error term is theoretical concept that can never be observed, but the residual is a real-world value that is calculated for each observation every time a regression is run. The reidual can be thought of as an estimate of the error term, and e could have been denoted as ^e.
What 5 numbers have a mode of 3 and a median of 4?
Well, honey, if you want a mode of 3 and a median of 4, you can have the numbers 3, 3, 4, 4, and 5. That way, 3 is the mode because it appears most frequently, and 4 is the median because it's smack dab in the middle. It's as simple as that, darling.
"IKYM" stands for "I Know You Missed." It is commonly used in text messaging and social media to indicate that the sender knows the recipient missed their message or call. It is a casual way to acknowledge the missed communication and often prompts the recipient to respond.
