Answer:
9.5
Step-by-step explanation:
To find the median, you have to sort the numbers in order by value:
1, 5, 6, 8, 11, 17, 18, 22
Next, you have to find the middle number:
Since there is an even amount of numbers, there are TWO middle numbers. In this case, the middle numbers are 8 and 11.
Now you have the find the value BETWEEN 8 and 11:
11-8 = 3.
3/2 = 1.5
So, the median is 9.5
X² - 169 = 0
x = ?
<span> Add 169 to both sides.
</span>
x² <span>− 169 + 169 </span>= <span>0 + 169</span>x² = 169
Square root
x = <span>± <span>√<span>169
</span></span></span>
<span><span>x = <span><span>13<span> or </span></span>x </span></span>= <span>−13
x can be 13 or -13.</span></span>
