Statistics
Statistics deals with collecting, organizing, and interpreting numerical data. An important aspect of statistics is the analysis of population characteristics inferred from sampling.

Lucy and her friends each have seven cards, as one third of 21 is 7.
42.
What do the intervals in a frequency chart have to be?
Usually the intervals in a frequency chart should be equal.
What are some examples of everyday use of integers?
If you brush your teeth 3x a day and you floss once a day, how long do you take?
How many 8 number combinations can you get with15 numbers?
15C8 = 15!/7!8! = 15*14*13*12*11*10*9*8!/7*6*5*4*3*2*1*8! = 2*13*11*5*9/2 = 6,435
What are all the possible combinations of 4 using only 3 variables?
I'm sorry what i was meaning what r all the 4 number combinations that can be made with 3 numbers.
Ie. 1111,1112,1113,1121,1122,1123,1131,1132,1133, etc.
In that case, we can think of it this way
For the first one, there is 3 possibilities, 1, 2, 3. For each one of them, the second one also have three possibilities, 1, 2, 3. Since there is three for every different first number, there is 9 possibilities for just the first two.
Hope you see the pattern, for all 4, it would be 3 x 3 x 3 x 3 which is 81 different possibilities.
Which type of graph is best suited for graphing the length of a person's hair over a year?
line graph
What does continuous and discrete?
"Continuous" means there's no smallest piece. If you pick two amounts, then
no matter how close together they are, there's always an amount between
them. Amounts of time, water, and temperature are continuous.
"Discrete" means there is a smallest piece. If you pick two amounts and they're
close enough together, there's no amount between them. Amounts of beans, cars,
and chickens are discrete.
What is the smallest 3 digits number that can rounded to the 200?
100 (rounded up to the nearest 200).
What is probability that she will pick a tennis of 4 that she has?

What are the dependent and independent variables of graham's liquid transmitter?
You might mean a device also known as the (Alexander Graham) Bell water microphone.
Sound waves impinging on a diaphragm connected to a needle cause the needle to move up and down in a weak acid solution. The variation in the resistance of the device as measured from the needle to the outside of the container of acid solution gives the microphone effect.
What matters is the amount of variation in resistance given the level of sound variation.
Therefore, the dependent variable would be some measure of the amount of variation in level of resistance of the device.
There are many possible independent variables, including:
- sound frequency
- dilution of the acid solution
- diameter of the needle
- diameter and circumference of the diaphragm
- strength of the sound
- circumference of the container for the needle
- viscosity of the solution
How many faces edgesand corners does a pyramid has?
A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n ≥ 3.
Assuming the term "largest" applies to both, 9999 - 987 = 9013
