A rational number is any number that can be express as a ratio integers whose decimal value is finite or at some point repeats with out end. (Any whole number <span> positive or negative- can be expressed as an improper fraction.</span>
Easy
median is the number in the middle when they are arranged in increasing numerical order
example
1,2,3
median is 2 becaus it is in middle
1,4,6,7,8
6 is median
if you have an even amount then average the middle two
1,3,5,7
median is the mean of 3 and 5 which is 4
so
3,5,7,11,23
median is 7 right now
there are an odd amout of numbers
adding 1 will result in even
to find the median of even set of numbers, average the 2 middle ones
right now 7 is center
the mean of 5 and 7 is 6
the mean of 7 and 11 is 9
we want a mean of 9
so add any number greater than or equal to 11
3,5,7,11,12,23 is one option
3,5,7,11,23,50 is another
mean is 9
mean is the average of them
x is the number to be added
6 numbers will be the set since there are 5 now and adding 1 will get 6
(3+5+7+11+23+x)/6=9
(49+x)/6=9
times both sides by 6
49+x=54
minus 49 both sides
x=5
the number added must be 5
to make the median of the 6 numbers 9, add any number greater than or equal to 11, such as 12 or 234
to make the mean 9, add 5 to the set
Answer:
x = 50
Step-by-step explanation:
I guess, this diagram tells us that the lines are parallel.
that means that they cut the third line at the exact same angles.
and that means
3x - 26 = 2x + 24
x - 26 = 24
x = 50
Given :
▪︎Length of height of this triangle = 16 cm
▪︎Length of base of this triangle = 4 cm
We know that :
Which means :
The area of this triangle :
▪︎Therefore, <u>the area of this triangle = 32 sq.cm</u>
