f(-2)=-6^2+(-2)+1 g(-2)=4-1

f(-2)=36+(-2)+1 g(-2)=3

f(-2)=34+1

f(-2)=35

f+g ------- 35+3 ------- 38

Tpy6a [65]

Answer:

65.54% (nearest hundredth)

Step-by-step explanation:

Given:

$\sf \mu=9000$

$\sf \sigma=1000$

$\sf X \sim N(\mu, \sigma^2)\implies X \sim N(9000,1000^2)$

P(X > 8600) = 1 - P(X ≤ 8600)

= 1 - 0.3445782584

= 0.6554217416

= 65.54%

The sum of two consecutive odd integers is -46

Answer: -31 l guess

explanation:The sum of two consecutive odd numbers is divisible by 4. An even number is divisible by 2, so it can be represented by 2n, where n is an integer. If we add 1 to an even number, then it will be odd. Therefore, an odd number can be represented as 2n + 1.
