What is the class interval if the range is 60 and the class number is 6?

If the values range from 0 to 60 and there are 6 classes, then the interval is 60/6 = 10.

What is 3 numbers with the median of 8 and the range of 5?

8,6,11

The median is 8 of course, 6, 8, 11

The range is 5, 11 - 6 = 5

There are many more options, this is just an example.

How may ordered pairs are in a linear graph?

Each ordered pair is made up of two numbers. A linear graph has an infinite number of pairs. An easy way to see this is look at the line y=x. This is a linear graph and any two of the same numbers will work! So there are an infinite number of ordered pairs.

What is the 3 quadrant on coordinate plane?

its ( - 2, - 5 )

Two number lines are perpendicularly bisected at their middle point in bi-dimensional Cartesian coordinate system for splitting the coordinate plane into four equal regions. The left-bottom side region is called the third quadrant. In this case, the region in the angle X ′ O Y ′ is the third quadrant and represented by a Roman numeral I I I.

How many tons go in to a pound?

A US ton is 2,000 pounds. Therefore, 1/2,000 of a ton = a pound.

But 2,000 pounds = a ton.

A UK ton = 2240 lb

What is the difference between quantitative and qualitative characteristic?

quantitative characteristics and observations made relating to numbers (like how many? or how much?), or those that can be measured (like in inches or pounds or liters, etc...).

qualitative characteristics are those that do not involve numbers. such as the color of an object or the feel or taste.

Is the mean and median similar?

The Mean is the average of a given set of values. The Median is the value that has

the same number of smaller values than the number of higher values, it is in the

middle of them. In a symmetrical distribution the Mean is equal to the Median. In an

asymmetrical distribution they have different value.

When does a set of numbers have no mode?

When data is grouped and each of the intervals or categories has the same relative frequency, then no mode can be calculated. This can happen when the dataset is very limited. If all numbers in a dataset are the same, then it is impossible to calculate a mode, no matter how the data is grouped. Sometimes the level of variation is so much less than our measurement capability that we can not detect variations in variables.

In the addition problem shown each letter represents a different digit from 1 to 9 If T is the only odd digit what number does TWO stand for ONE plus ONE equals TWO?

ONE + ONE = TWO can be written as 2 x ONE = TWO

As T is the only odd number then E is an even number such that 2 x E produces a units digit that is the final digit of TWO and also the first digit of ONE

If E = 2 then 2 x 2 = 4 : 2 x 4N2 = TW4. As T is odd then it must be > 8 and is thus 9.

N (which is an even number) must be >5 and is thus 6 or 8. If N = 6 then 2 x 462 = 924. As E = 2 then W cannot = 2. When N = 8 then 2 x 482 = 964 which is a valid answer.

If E = 4 then 2 x 4 = 8 : 2 x 8N4 produces a 4 digit product and is thus invalid.

If E = 6 then 2 x 6 = 12 : 2 x 2N6 = TW2. T must be 5 and thus N can only be 8 (as E = 6) then 2 x 286 = 572. W is therefore an odd number and is thus invalid.

If E = 8 then 2 x 8 = 16 : 2 x 6N8 produces a 4 digit product and is thus invalid.

The only solution is when TWO represents 964.

How many four digit number are there using the numbers 0 1 2 3 4 5 6 7 8 9?

Um, that's all the digits, unless they've recently added some and I didn't get the memo. So you're basically asking "how many four digit numbers are there"?

I'll assume you're excluding those with leading zeros.

So the four digit numbers are 1000-9999, inclusive, which is exactly 9000 of them.

Why do charts and graphs need titles?

So people looking at the chart or graph will know what it depicts.

What does vigorus means?
