Round 297.85 square kilometer to the nearest tenth of a square kilometer?
297.8 square kilometres.
Now here is a minor digression that you may (or may not) find is of interest:
There are different views on how the digit 5 should be rounded - up or down. 1,2,3 and 4 are always rounded down; 6,7,8 and 9 are always rounded up and 0 does not need rounding. So if you always round 5 down, you will round down 5 numbers and up 4 and so introduce a downward bias in your work. Conversely, if you always round up you will introduce an upward bias. You could randomly decide to round up or down but this makes it more difficult for others to follow what you have done. The recommended answer is to round 5 so that the previous digit is EVEN.
Thus 0.15 is rounded up to 0.2
and 0.45 is rounded down to 0.4
For a continuous distribution - which is what we are considering here - the probability of something being EXACTLY a specific value is zero. This is basically because there are infinite many possible values. You will only ever consider ranges of numbers, such as the probability of something being 1 and 2.
What type of line is straight and shows the general trend of the data on a graph?
Of course, this question assumes that the data is linear. It could also be quadratic, exponential, logarithmic -- all of these are quite common with data. Then it becomes a curve of best best.
How many permutations can you get from the digits 0489?
Twenty-four. You have four choices for the first digit. Once selected, you have three choices for the second digit. Then two for the third and then the last digit.
Multiply 4 X 3 X 2 X 1 and you get 24, which is 4! or "4 factorial".
How do you multiply 2 digit numbers times 2 digit numbers?
You line them up and down and then multiply the first ones up and down on the right. then you do the diagonally ones and then you put a zero on the bottom right. then you go to the second number on the right and do the one diagonally and then the on up and down. then you add the two together and you have your answer.
example:
A negative correlation
How many three digit combination can be made out of 4-1-8-7-2-9-0-3-6?
If you don't use any digit more than once, there are 83 combinations: 418 417 412 419 410 413 416 487 482 489 480 483 486 472 479 470 473 476 429 420 423 426 490 493 496 403 406 436 187 182 189 180 183 186 172 179 170 173 176 129 120 123 126 190 193 196 103 106 136 872 879 870 873 876 829 820 823 826 890 893 896 803 806 836 729 720 723 726 790 793 796 703 706 736 290 293 296 203 206 236 903 906 and 936
What is the independent and dependent event for pulling two marbles out of a bag?
The first marble is the independent event because its probability is only based on the sample space of the bag. The second marble is the dependent event because its probability is based on the sample space of the bag which has now been changed by the first marble.
What is an easier way to produce a three-digit number that has 3 as a factor?
Easier than what? The easiest way to produce a three-digit number that is a multiple of 3 (has 3 as a factor) is to make sure the digits total to a multiple of 3. 123, 555, 498 are all multiples of 3.
What graph can the measures of central tendency not be found?
A categoric chart - pie or bar.
For example, answers to what is your favourite fruit?
