Let denote the missing number with x. So we have:
(76 + 78 + 81 + x)/4 = 85
(235 + x)/4 = 85
(4)(235 + x)/4 = (4)(85)
235 + x = 340
235 - 235 + x = 340 - 235
x = 105
the mode is how muck times the number come up example:5,6,7,8,5,5,6 the answer would Be 5 caues it comes up the most a good way it to tally off the numbers you have already counted so you don't get confused.
A dice has six sides, so it has a chance of one-in-six of landing on one particular side. Therefore, one with two 2's would have a chance of one in three of coming up.
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
There are infinitely many rational numbers, but there are infinitely more irrational numbers than rational numbers. There are more irrational numbers between 0 and 1 than there are rational numbers period.I was kind of guessing what you were trying to ask, so let me explain some background in case that wasn't quite it. Rational numbers are those that are representable as the ratio of two integers: 2/3, 355/113, 5 (=5/1). Irrational numbers are those that cannot be represented exactly by the ratio of two integers; some familiar irrational numbers are pi and the square root of 2. There are an infinite number of integers, and therefore an infinite number of rational numbers, but the two infinities are of the same order of magnitude (called a countable or listable infinity). The mathematical designation for the kind of infinity that the integers have is called aleph-null. There are also an infinite number of irrational numbers, but it's a "bigger" kind of infinity called C or the "power of the continuum." There's a relationship between aleph-null and a larger infinity called aleph-one. It's not known whether C and aleph-one are the same or not, and if they're not, we don't know which is bigger.
Oh, what a lovely math problem we have here! Let's paint a happy little picture with numbers. If the larger number is 4 times the smaller number, and their difference is 36, we can see that the smaller number is 9 and the larger number is 36. Just like painting a beautiful landscape, sometimes all we need is a little patience and perspective to see the whole picture come together!
If three of the four numbers are 79, 80, and 65, and the average is 85, then the final number will equal (85 x 4) - 79 - 80 - 65 = 116.
If you have to find a median in a set of numbers in which there are an even number of entries, you must find the average of the two numbers the come in the middle.
You are calculating the average of TWO numbers: 766+878 = 1,644 now divide 1,644 by 2 = 822.
There are an infinite number of different numbers in that range.But there's only one single number that's exactly in the middle, dead-center, halfwaybetween them. It's called the "average" of 7.05 and 7.195 . That number is 7.1225 .

Yes, any positive or negative number is a real number, including 0. Non real (or imaginary) numbers are the ones that have an "i" or "j" such as j1.5 or 1.5i The imaginary numbers come from expressions like sqrt(-1), its impossible to come up with a real answer so the imaginary one would be 1i or i
On the number line they do.
Yes. Its rational because you know what number is going to come next. If the numbers were in a random order it would be irrational.

It is defined as the average of a group of numbers. See the related link for more information.The mean in math is the average of a group of certain numbers.
There are infinitely many decimals between any two given (different) numbers. If you want the number exactly in the middle, take the average of the two numbers.
