The two problems would be approached differently.

What is the greatest 4 digit number that rounds up to 1000?

Rounding up implies the number is smaller than 1000. However, a number smaller than 1000 cannot be a 4-digit number. So there cannot be such a number.

What was said is wrong. The greatest 4 digit number that rounds up is 999.9

When it is most appropriate to report the mean median and the mode?

meadian- you take the biggest and smallest number and subract both of them

mode- the number that is constantly repeating itself over and over again

mean-you take the biggest and smallest number and add them both together

How is an ordered pair related to the coordinates on a graph?

The ordered pair IS the coordinates on the graph. If you have the ordered pair (1,2) that means the value of x is 1 and the value of y is 2, so to get to that point on a graph from the origin (center) you would move right 1 unit and up 2 units.

How do you make a problem with mean median and mode?

mean is just if you sum up all samples and divide it by the number of samples

median is the one in the middle. so you could sort your samples and then "delete the highest and lowest" until you only have one

mode is the thing i can't remember

How many kids get injured per year?

Each year, millions of children experience injuries, with estimates suggesting that around 9 million children visit emergency rooms for unintentional injuries in the United States alone. These injuries can range from minor incidents like cuts and bruises to more severe cases involving fractures or concussions. Globally, the World Health Organization reports that injuries are a leading cause of death and disability among children, particularly in low- and middle-income countries. Efforts to enhance safety measures and education are crucial in reducing these statistics.

Is the 50th percentile of a distribution the same as the distribution mean?

How many pounds is 752 cc?

How DFD difffer from flow chart?

Flow Chart is a generic term, and DFD is a specific one. Data Flow Diagram (DFD) is a data flow chart to illustrate the data flow/store/change in a component/system/product from the input to the output.

A set of five numbers has a mode of 12 a median of 11 and a mean of 10 what could the numbers be?

These are your 5 numbers:

X X X X X

the median (the middle number of a row) is 11, that means:

X X 11 X X

the mode (the most frequent number in a row) is 12, that means:

X X 11 12 12

the mean (the average) is 10, that means:

(X+X+11+12+12)/5=10

or: X+X+11+12+12=50

or: X+X=50-12-12-11

or: X+X=15

so the remaining numbers must be 15 combined, and lower then 11, that means they can be:

5 and 10

6 and 9

7 and 8

so you have 3 possible solutions:

5 10 11 12 12

6 9 11 12 12

7 8 11 12 12

What are the solutions to 2y-2x equals 10?

y - x = 5 so:

x = 1, y = 6 and all increments (and decrements) of 1 in each term, so there are an infinite number of solutions.
