Mode means the number that apperss the most
median is the number in the middle when you arrange them in numerical order
ok so
you take the unbers fom the left most collumn and pair it with each number in the right side of the line, the left collumn is the tens place and the right hand side is the ones
so the th enumbers are
32,41,41,50,56,57,62,70,70,72,72,72,73,74,91,92,94,94,94,94
mode=most common number
94 appears 4 times which is most
mode=94
median is number in very middle number
20 terms
72 is in middle
mode=94
72=median
D is answer
The answer is: 83 + 12√35
(a + b)² = a² + 2ab + b²
In (2√5 + 3√7)², a = 2√5, b = 3√7
Just substitute a and b:
(a + b)² = a² + 2ab + b² = (2√5)² + 2 * 2√5 * 3√7 + (3√7)² =
= 2²√5² + 2 * 2 * 3 * √5 * √7 + 3²√7² =
= 4 * 5 + 12 * √(5*7) + 9 * 7 =
= 20 + 12 *√35 + 63 =
= 83 + 12√35
16 because 3 divided by 8 is 0.375 and 6 divided by 0.375 is 16.
Y= 3(3)–2(3)2+5(3)3
y= 9–2*3*2+5*9
y=9–12+5*9
y=9–12+45
y=42
