Answer:
(x1 + x4)/2 = 4
Step-by-step explanation:
(x1 + x2+ x3 + x4)/4 = 5 mean
x1 , x2 , x3 , x4
median (x2+x3)/2 = 6
(x2+x3) = 12
The smallest integer is x1, the largest integer x2.
The mean of the largest and smallest of the integers is (x1 + x2)/2.
(x1 + x2+ x3 + x4)/4 = 5
x1 + x2+ x3 + x4 = 20
x1 + 12 + x4 = 20
x1 + x4 = 20 - 12
x1 + x4 = 8
(x1 + x4)/2 = 8/2
(x1 + x4)/2 = 4
Answer: C- 12.73 Z- 2
Step-by-step explanation:
Step-by-step explanation:
= (x - 7)(x² + 3x - 3)
= x³ - 7x² + 3x² - 21x - 3x + 21
= x³ - 4x² - 24x + 21
