Given the set of numbers (3, 5, 7, 11, 23), what number must be added to the set so that the median of the 6 numbers is 9? what
Gennadij [26K]
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

Find the possible value or values of n in the quadratic equation 2n2 – 7n + 6 = 0.
nika2105 [10]
2n^2 - 7n + 6 = 0\\
2n^2-4n-3n+6=0\\
2n(n-2)-3(n-2)=0\\
(2n-3)(n-2)=0\\
n=\dfrac{3}{2} \vee n=2

Hey so I'm a 15 year old in Geometry HN and I have my SOL tomorrow, (baisaclly state testing) I've been stuffy for weeks now yet
Digiron [165]

Answer:

2: 86

3:64

4: 77

6: 3

7:12

8: O=110 X:110

Step-by-step explanation:

Number 2 shows what is called a central angle. Central Angles are equivalent to the ark length

Number 3 shows an Inscribed angle. These angles are half of the ark but in your question, it is twice the angle measurement

Number 4 you want to divide the ark length by two when the angle is not given. And when the angle is given you want to mutilate by two

Number 6 is Overlapping Ark which means they are both congruent to each other because the ark is equivalent to each other.

Number 7 is x=12 because 5x+12 is twice the measure of 3x

Number 8 o=110 because a circle has 360 degrees so you want to add them up and then subtract that from 360. x is also 110 degrees because it is a central angle, which is the same amount of degrees as the ark length.
