X is between 80 and 90, if the square root of a number (x) is 9, you would do 9x9 to solve for x, x=81
Based on the given stem and leaf plot of the scores of the ninth and tenth graders, the difference between the tenth and ninth-grader modes <u>is 7.</u>
<h3>What is the tenth grade mode?</h3>
The mode is the score that appears the most times.
From the stem and lead plot, this number is 42 as it appears 3 times. This is shown by the 4th stem having 2 leafs three times.
<h3>What is the ninth grader mode?</h3>
The third stem has five leafs four times so the mode would therefore be 35.
The difference is then:
= 42 - 35
= 7

Answer:
x=13+√-13 or x=13-√-13
Step-by-step explanation:
Using the method of completing the square roots:
x²-26x=-13-169
x²-26x=-182
x²-26x+(-13)²=-182+(-13)²
(x-13)²=-182+169
(x-13)²=-13
Take square roots of both sides
(x-13)=√-13
x=13±√-13
That can also be written as
X=13+√13i,13-√13i
