Answer:
k = - 2
Step-by-step explanation:
( 2x - y )²
Formula : -
( a - b )² = a² + b² - 2ab
Here,
a = 2x
b = y
( 2x - y )²
= ( 2x )² + y² - 2 ( 2x ) ( y )
= 4x² + y² - 4xy
So,
( 2x - y )² = 4x² + y² - 4xy
( 2x + y )²
Formula : -
( a + b )² = a² + b² + 2ab
Here,
a = 2x
b = y
( 2x + y )²
= ( 2x )² + y² + 2 ( 2x ) ( y )
= 4x² + y² + 4xy
So,
( 2x + y )² = 4x² + y² + 4xy
( 2x - y )² - ( 2x + y )²
= 4x² + y² - 4xy - ( 4x² + y² + 4xy )
= 4x² + y² - 4xy - 4x² - y² - 4xy
= 4x² - 4x² + y² - y² - 4xy - 4xy
= 0 + 0 - 8xy
= - 8xy
( 2x - y )² - ( 2x + y )² = 4xyk
- 8xy = 4xyk
Divide 4xy on both sides,
- 8xy / 4xy = 4xyk / 4xy
- 2 = k
k = - 2
Therefore, the value of k is - 2.
Answer:
mode = the most
mean =average of the numbers: a calculated "central" value of a set of numbers. ... add up all the numbers, • then divide by how many numbers there are.
median=The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).
<h3>
Mark</h3>
Now we arrange all Mark's test scores first (arrange in a sequence), so it will become :
71, 74, 76, 82, 83, 94, 94
mode = 94
mean = (71 +74+76+82+83+94+94) over 7
= 574 over 7
= 82
median = 82
<h3>
Irina</h3>
Now we arrange all Irina's test scores first (arrange in a sequence too) , so it will become :
79, 79, 82, 83, 89, 95, 95
mode (there are 2 modes in Irina test) which is 79 and 95 because both of them appears twice.
mean = (79+79+82+83+89+95+95) over 7
= 602 over 7
= 86
median = 83
