Median is the middle value, if you have an even number of values in the data set, add the two middle numbers and divide that by two. If you have an odd number in the data set, it would be the middle number.
Upper quartile is the middle value of the upper half of numbers in the data set, The upper half of numbers are the numbers below the Median. Use same way as the median to find the value.
Minimum is the lowest number in the set.
Maximum is the highest number in the set.
Lower quartile is the middle value of the lower half of numbers in the data set, The lower half of numbers are the numbers above the Median. Use same way as the median to find the value.

Answer:
ΔLNO ≅ ΔLMN iff ∠LNO = ∠LNM
Step-by-step explanation:
Lets get started using the statement that...
<em> In ΔLON and ΔLMN</em>
<u><em> Side ON ≅ Side MN </em></u>
<u><em> Side LN ≅ Side NM </em></u>
<u><em> ∠LON ≅ ∠LMN</em></u>
To Prove: ∠LON ≅ ∠LMN by ASA congruence theorem.
Solution: In order to prove ASA congruence between the triangles we need two angles to be congruent to each other. When we look at the figure, we see that <u><em>∠LNO ≅ ∠LNM is a common angle </em></u>in both the triangles.
Hence, using this we will prove that the triangles are congruent by ASA congruence rule.
<u><em>In ΔLON and ΔLMN</em></u>
Side ON ≅ Side MN
∠LNO ≅ ∠LNM ( ∵ common )
∠LON ≅ ∠LMN (∵ Given )
<u>⇒ ΔLON ≅ ΔLMN ( By ASA congruence theorem).</u>
Use the Pythagorean theorem:
x^2 + 6^2 = √117 ^2
x^2 + 36 = √117 ^2
Simplify"
x^2 + 36 = 117
Subtract 36 from both sides:
x^2 = 81
Square both sides:
X = 9
Answer:
x²
Step-by-step explanation:
x³ - 1 ÷ x + 2
the first term of the quotient is x³ ÷ x = x²
500 * 25%
= 500*1/4
=125 1st time marked down.
Then, 500-125 = 375
375 * 25%
=375*1/4
=93.75 2nd time marked down.
Then, 375-93.75 = 281.25
281.25 * 25%
=281.25*1/4
=70.31 3rd time marked down.
Then, 281.25 - 70.31 = $210.94
The final price is $21.94
