Step-by-step explanation:

Fill in the given number and solve for x. The answer is 1000x, rounded.

  C=\sqrt{0.2x+1}\\\\1.5=\sqrt{0.2x+1} \quad\text{use given value for C}\\\\2.25=0.2x+1 \quad\text{square both sides}\\\\1.25=0.2x \quad\text{subtract 1}\\\\6.25=x \quad\text{multiply by 5}

x is in thousands, so 6.25×1000 = 6,250 passengers flew in June.

Veseljchak [2.6K]

Answer:

12

Step-by-step explanation:

Put numbers in order from least to greatest.

8,8,9,9,10,11,13,14,14,14,15,16.

Find the number in the middle.

Because 12 is an even number we have to take the two middle numbers, in this case 11 and 13, add them and then divide that number by 2.

11+13= 24

24 ÷ 2 =12

So the median weight is 12.
