Answer:

an =6n

Step-by-step explanation:

6, 12, 18, 24

Take the 2nd number minus the first number, 3rd minus the second, etc

12-6 =6

18-12 = 6

24-18 =6

The common difference is 6

The formula for an arithmetic sequence is

an =a1+d(n-1)

where a1 is the first term

d is the common difference

n is the term number

an = 6+6(n-1)

Distributing

= 6+6n-6

= 6n

Answer: 0.3413

Step-by-step explanation:

Given: an American household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard deviation is 2 pounds.

Let $\mu=\text{ 28 pounds and }\sigma=\text{ 2 pounds}$ .

Let x be the random variable that denotes the amount of newspaper for garbage generated by each household each month.

If the data conforms to a normal distribution and a household is selected at random, the probability of its generating between 28 and 30 pounds per month is about

$P(28$

Hence, the required probability is 0.3413.

Two numbers are shown on the number line. 79 3 270 Which value is NOT located between these two numbers on the number line? A B)

erik [133]

the number not located between √9/3 and 2π on the number line is π/9 (option C)

Explanation:

We need to find the numbers between √9/3 and 2π

(√9)/3 = 3/3 = 1

using π as 3.14

2π = 2(3.14) = 6.28

Now we need to check the options for numbers that do not fall between 1 and 6.28:

a) π = 3.14

This number falls between 1 and 6.28

b) √9 = 3

This number falls between 1 and 6.28

c) π/9 = 3.14/9 = 0.35 (approximately)

This number doesnot fall between 1 and 6.28

d) π²/9 = (3.14)²/9 = 1.10 (approximately)

This number falls between 1 and 6.28

Hence, the number not located between √9/3 and 2π on the number line is π/9 (option C)
