Answer:
u <= 80
u > 80
Step-by-step explanation:
The happiest would be
Null hypothesis: u <= 80
Alternative hypothesis: u > 80
First of all, find the first number more than 100 that can divided by 9, and it's 108 (we'll call it as 'a') then, find the number less than 2000 that can divided by 9, it's 1.998 (we'll call it as 'Un')
Un = a + (n-1).b
1998 = 108 + (n-1).9
1998 = 108 + 9n -9
1899 = 9n
211 = n
and the total is
Sn = n/2 (a+un)
s211 = 211/2 (108+1998)
= 222.183
Your answer is c or 3 however you want to say it
3/6 = 1/2
3/6 divided by 3
Answer:
2nd option
Step-by-step explanation:
8
- 4x³ - x + 2 - (2 - 8x² - x + 10) ← distribute by - 1
= 8 - 4x³ - x + 2 - 2 + 8x² + x - 10 ← collect like terms
= 6 - 4x³ + 8x² - 8
