Linda received the following scores on her essay tests.
64, 65, 63, 66, 60, 65, 66, 68, 69, 66, 63
What is the median of her scores?

65

Step-by-step explanation:

Median is the middle number when arranged in ascending order.

To find median , we must arrange the given scores in ascending order , that is

60 , 63 , 63 , 64 , 65 , 65 , 66 , 66 , 66 , 68 , 69

After arranging in ascending order , the number in the middle is 65,'

Therefore , the median score is 65

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
