if an ordered pair is a solution, it should satisfy the equation.
see the first option
, if you put $x=4$ and $y=12$
you'll get $12=12$ which is true.
now the last option, $y=8-x$ put $x=4$ and $y=12$
$12=8-4\implies 12\ne4$ thus it is not a solution.
So option 4 is correct
Answer:
<h2>Question:</h2>
- The amount of vitamin C found in one cup of six varieties of orange juice is shown below. What is the median amount of vitamin C in the different varieties?
- 104 mg, 85 mg, 83 mg, 100 mg, 89 mg
<h2>Solution:</h2>
- First thing first, we've to arrange the data in an ascending order
<em>=></em> 83mg ,85mg ,89mg ,100 mg ,104 mg
- Now ,Since the no. of observation is odd(<em>here,</em><em>5</em><em>)</em>, we'd apply this formula
- Where ,n= <em><u>No.</u></em><em><u> </u></em><em><u>of </u></em><em><u>observations,</u></em><em><u> </u></em>
- Hence, the median of the above data
- is the third observation ↦89mg
Hope it helps

The measurements that show equal length is 15 yd and 540 in, 195 ft and 2340 in, 5280 yd and 15840 ft
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
1 ft = 12 in; 1 yd = 3 ft and 1 yd = 36 in.
Hence:
15 yd = 15 yd * 36 in per yd = 540 in
195 ft = 195 ft * 12 in per ft = 2340 in
5280 yd = 5280 yd * 3 ft per yd = 15840 ft
The measurements that show equal length is 15 yd and 540 in, 195 ft and 2340 in, 5280 yd and 15840 ft
