Real numbers are numbers that are all on the number line. They can be negative and positive. Also, the number 0 can be a real number.
Hope this helps
sum the parts of the ratio, 5 + 6 = 11 parts
Divide the sum by 11 to find the value of one part of the ratio.
77 ÷ 11 = 7 ← value of 1 part of the ratio , thus
6 parts = 6 × 7 = 42 ← larger number
n and (n - 1) are consecutive integers.
We are given 'n', a positive integer.
This 'n' can either be odd or even.
When 'n' is odd
The n - 1 is even.
Note that the product of odd and even is always even. That is the product of n and (n - 1) is even.
when 'n' is even
Then n - 1 is odd.
Again, using the similar logic we can say that the product of n and n - 1 should be even because here, 'n - 1' is even and 'n' is odd.
The number . . . M
The square of the number . . . M²
Two more than the square of the number . . . M² + 2
You said that this is equal to 123, so we can write M² + 2 = 123
That's the equation we have to take and solve for ' M '.
Subtract 2 from each side of the equation, and you have M² = 121 .
Take the square root of each side: M = √121 .
The Mystery number is the square root of 121.
If you don't happen to know what that is, then you can use your pocket
calculator, or the calculator that comes with your computer (if you know
how to find it). They will all tell you that the square root of 121 is 11 .
That's a fine and wonderful answer, but technically, it's only half of the
answer. Any equation that has something squared in it almost always
has two solutions, and this one does.
The square root of 121 is a number that gives you 121 when you
multiply it by itself. ' 11 ' does that: (11 x 11) = 121 . Is there another
number that does the same thing ?
How about ' -11 ' ? Look at this: ( -11 x -11 ) = 121 . (Remember that
if both numbers being multiplied have the same sign, then their product
The bottom line is: The mystery number is +11 and also -11 .
Either one does what you want . . . When you square it and then
add 2 more, you get 123 either way.
To multiply fractions you need to cross multiply
Example: Cross Product 4(x) = 5(12),
Multiply 4 = 12,
Divide x = 12/5,
Simply x = 2.4
seems like d
median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.
say you have 3,8,7,3,1,9,8 order them from lowest to highest
if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.
so you would remove the 1 and 9 leaving you with 5 digits remaining
when you've reached the middle that would be your answer so in this case the answer is 7
if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6
good luck on that project hoped i you at all
