Answer:

Geometric

Step-by-step explanation:

Given terms are {3, -1, 1/3, -1/9............}

If we have common difference between the terms then it is arithmetic

If we have common ratio between the terms then it is Geometric

Difference of 3  and -1  is 4

Difference of 1/3  and -1 is -4/3

Common difference it not same so it is not Arithmetic

Now we check common ratio

we divide second term by first term

first term is 3  and second term is -1

\frac{-1}{3}

now we check with next two terms

\frac{\frac{1}{3}}{-1}=\frac{-1}{3}

common ratio is -1/3

So this is Geometric

An iceberg weights 450,000 pounds. If it loses 0.2% of its weight in a day, what is its new weight at the end of the day?
Papessa [141]

Answer:

449,100 pounds

Step-by-step explanation:

.2% as a decimal is 0.002. To find .2% of 450,000, you multiply it. The answer is 900 pounds. Because it is losing that amount, you subtract it. 450,000-900= 449,100 pounds

How do you simply 2x+8=-6
photoshop1234 [79]
To simplify <span>2x + 8 = -6, the easiest way is to manipulate the equation one step at a time:

</span>2x + 8 = <span>-6
</span>2x = <span>-14             (subtract 8 from both sides)
</span>x = -7                 (divide both sides by 2)

Gill Rolls a number Cube 78 times how many times can he expect to roll a number greater than one
saul85 [17]
Argument
The only number he can't roll is the number one. There are 5 numbers that he can roll.

The probability of success therefore is 5/6.

Formula
Number of successful rolls = probability of success * total number of rolls.
Total number of rolls = 78
Probability = 5/6

Number of successful Rolls = 5/6 * 78 
Number of successful Rolls = 390/6
Number of successful Rolls = 65

Answer
He should roll a number greater than one 65 times <<<<< answer
