Hello!
First of all, we need to order the numbers least to greatest.
73,79,82,85,85,85,85,86,87,88,90,91,91,92,92,94,97
As there is an odd number, one of the numbers in our data set is the median. If we subtract this number, we would have 16. If we split that we have 8 on each side. So, to find the number in the middle, we find the 9th number.
If you count, you see that the middle number is 87.
Therefore, the median is B) 87.
I hope this helps!
Answer:
(6,3,0)
Step-by-step explanation:
Given,
x - y + 0z = 3
6x - 0y - 2z = 36
0x + 6y + 2z = 18
You have the following augmented matrix:
(1) 1 -1 0 3
(2) 6 0 -2 36
(3) 0 6 2 18
Let's (3) add to (2) and divide by 6
(1) 1 -1 0 3
(2) 1 1 0 9
(3) 0 6 2 18
Now, let's (2) add to (1) and divide by 2
(1) 1 0 0 6
(2) 1 1 0 9
(3) 0 6 2 18
Let's (3) ÷ 2
(1) 1 0 0 6
(2) 1 1 0 9
(3) 0 3 1 9
Let's (1) subtract from (2)
(1) 1 0 0 6
(2) 0 1 0 3
(3) 0 3 1 9
Finally, let's (2) multiply by 3 and subtract from (3)
(1) 1 0 0 6
(2) 0 1 0 3
(3) 0 0 1 0
Thus,
x = 6, y = 3 and z = 0
The answer is (6, 3, 0)
We have to verify the answer
6 - 3 = 3 ⇒⇒ 3 = 3
6*6 - 5*0 = 36 ⇒⇒ 36 = 36
6*3 + 2*0 = 18 ⇒⇒ 18 = 18
Answer:
I'm sorry did you ever get the answer to this question
X=15
you do 2(5x-5)=(6x+50) and simplify, then you get x=15.
y=7
Once again, you do (5y+5)=(7y-9) and simplify. you get y=7.
please leave a thanks and mark brainliest if you can
