Arithmetic series help!!!!

Answers

Answer 1

Answer:

The initial term of the sequence is 15. The common difference is 3, so the n-th term (an) is

... an = 15 + 3(n-1)

For n=14, the 14th term of the sequence is

... a14 = 15 + 3(14 -1) = 54

The sum of terms is the average of the first and last, multiplied by the number of terms:

... sum = (15 + 54)/2·14 = 7·69 = 483

The appropriate answer choice is

... 54; 483

Hello!

First you have to find the probability of a pulling a penny

To find this you put the amount of pennies over the amount of coins

There are 12 coins and 5 pennies

This is a 5/12 probability

Next you have to find the probability of then pulling out a quarter

Since you already took out a coin the total amount is now 11

The probability is 4/11

You multiply the two probabilities together to get the probability of them happening one after antoher

5/12 * 4/11 = 5/33

The answer is D)5/33

Hope this helps!

There are 1,000 fish in a lake. Each year the population declines by 15%, but afterward, the lake is restocked with 500 aditional fish. Write a recursive rule to find the number of fish in the lake for any year

Answers

We begin with 1,000 fish in a lake.
Each year the population declines to 15%
Then they put back 500 fish in the lake.

The equation: (1000 * .85) +500

Find the product. y^5·y^3

Answers

The product of the exponential expressions are $A = y^(8)$ .

Given data:

The first expression is represented as p.

The second expression is represented as q.

The value of $p=y^(5)$

The value of $q=y^(3)$

So, the product is A = p * q

Substituting the values in the expression:

$A=y^(5) *y^(3)$

From the laws of exponents:

$m^(a)*m^(b) = m^(a+b)$

So, $A = y^(5+3)$

$A = y^(8)$

Hence, the product is $y^(8)$ .

What is the percent increase of 10 to 24?

Answers

The percent of increase is 140%

Work is provided in the image attached.

Have a great day!

Let me explain it like this. add an extra 0 after 10 and you have 100 so every time you add 10 to the original number you are adding 100% so your answer would be 140%
