Find the middle number if there is an even amount of numbers take the two middle numbers add them together in divide them by two
In this case it would be 2+2=4 ÷2= 2
Two is the median
Answer:
x = 8
Step-by-step explanation:
By first drawing a photo, pasted below, you can plot your points. Then use the formula:
a/c = b/d to plan out your equation
3x - 8/x = 16/x
Cross multiply so you then have:
16x = 3x^2 - 8x
24x = 3x^2
8 = x
To check:
3(8) - 8 = 16
24 - 8 = 16
16 = 16
<span>Center City West = x
</span><span>Center City East = (x + 257)
Solve for x to find the capacity for Center City West and then we can find the capacity for Center City East.
(x + 257) + x = 1221
x + x + 257 = 1221
2x + 257 - 257 = 1221 - 257
2x = 964
2x / 2 = 964 / 2
x = 482
</span><span>Center City West capacity = 482
</span>
Now to find Center City East capacity we substitute 482 for x in (x + 257)
(x + 257)
(482 + 257)
482 + 257 = 739
Center City East capacity = 739
Center City West capacity = 482
Two answers are possible.
One is with the repetition of digits.
The other is without repetition of digits.
ANSWER 1: With Repetition
Numbers: 1,2,4,5,7,8
There are 4 digits __ __ __ __
1st digit can be filled by any of the 6 numbers.
Similarly 2nd, 3rd and 4th digits.
Hence each digit will have 6 possibilities.
Therefore no.of 4 digit numbers that can be formed are 6 x 6 x 6 x 6 = 1296
ANSWER 2: Without Repetition
4 digits __ __ __ __
Now the first digit can be filled by any of the six numbers. Therefore there are 6 possibilities
The second digit will have only 5 possibilities as one of the numbers gets used up by the 1st digit.
Similarly the 3rd and 4th digits will have 4 and 3 possibilities respectively.
Therefore no.of 4 digit numbers that can be formed are 6 x 5 x 4 x 3 = 360
