In math what does secondary data mean?
Secondary data means the information was gathered somewhere else.ex. Newspaper,news..ect
How many 3 number combination art there in the numbers 1 to 9?
If no digit is repeated, then there are (9 x 8 x 7)/(3 x 2) = 84 combinations.
What is 25 over 88 as a percentage?
Expressed as a percentage, 25/88 x 100 = 28.409 recurring (that is, 28.4090909...) percent.
If a probability distribution curve is bell-shaped then this is a normal distribution?
True
* * * * *
No. The Student's t-distribution, for example, is also bell shaped.
(1,1) = 1 (1,2) = 2 (1,3) = 3 (1,4) = 4 (1,5) = 5 (1,6) = 6
(2,1) = 2 (2,2) = 4 (2,3) = 6 (2,4) = 8 (2,5) = 10 (2,6) = 12
(3,1) = 3 (3,2) = 6 (3,3) = 9 (3,4) = 12 (3,5) = 15 (3,6) = 18
(4,1) = 4 (4,2) = 8 (4,3) = 12 (4,4) = 16 (4,5) = 20 (4,6) = 24
(5,1) = 5 (5,2) = 10 (5,3) = 15 (5,4) = 20 (5,5) = 25 (5,6) = 30
(6,1) = 6 (6,2) = 12 (6,3) = 18 (6,4) = 24 (6,5) = 30 (6,6) = 36
Out of 36 possibilities, 6 + 5 + 3 + 2 + 2 + 1 = 19 fit the requirements.

What do you notice about the distribution of volcaneos?
They tend to occur over pockets of magma and along the edges of tectonic plates
What is an important difference between the uniform and normal probability distributions?
The uniform distribution is limited to a finite domain, the normal is not.
What is the mean median mode and range of 15 96 82 79 97 97 47 56 70?
Please do not be lazy and ask for other people to do the work for you. That doesn't not help you or improve your skill in mathematics. But, I will help you anyways.
Mean (add all of the numbers and divide by the quantity of numbers to get the average) - 71
Mode (the most frequent number in the number group) - 97
Median (the middle of the group of numbers in order) - 79
I hoped this helped you out. Please, next time try to work on this yourself.
How many spades appear on the ace of spades in a standard deck of cads?
There is one large spade in the middle. And one spade below each A on the card. So there are three spades.
What is the difference between a form of energy and sound energy?
Truly there can be no diffence in either for they still are a pure form of energy.
What do you learn about bar chart?
Bar chart consists of "x" axis 7 "y" axis which are been represented at the left vertical side & the bottom side respectively. To study the bar graph we have to first see what information is that chart telling u about 7 then see the units [if any]. And then to read the graph we first have to draw a parallel line from the top of the graph & joining to the x-axis. On the x-axis there r some measurements. Form that find the one {measurement} on which the line which u have drawn from the bar. Do the same with the y-axis too. And then u get the answer.
There is no such number, although I am struggling to prove it.
