Patrick wants to estimate the number of rabbits on his university campus. One day he catches 25 rabbits. He puts a tag on each rabbit. He then releases the rabbits back onto the university campus. The next day he catches 16 rabbits. 5 of the rabbits he catches on the second day have a tag on them. Assuming that there is a fixed population size for the rabbits and that he catches the rabbits in a random way, work out an estimate for the total number of rabbits on the university campus.

To increase an amount by 22%, multiply by?

Answers

Multiply by .22 then add that answer to what you multiplied. For example, you need to increase 100 by 22%. 100 × .22 = 22. 100 + 22 = 122

Final answer:

To increase a given amount by 22%, you should multiply the original amount by 1.22. This conversion results from adding the 22% increase to the 100% of the original amount, thus totaling 122%, or 1.22 when expressed in decimal form.

Explanation:

To increase an amount by 22%, you should multiply the original amount by 1.22. This is because the original amount is considered 100%, or 1 when we talk in decimal terms. To find a 22% increase, you add this percentage to the 100% of the original, making a total of 122%, which translates to multiplying by 1.22 in decimal.

For instance, if you have a value of 50 and you want to increase it by 22%, you multiply 50 by 1.22 (50*1.22 = 61). Therefore, a 22% increase of 50 is 61.

Brad sold candy bars and cookies for a fundraiser at school. Candy bars sold for $3 and cookies sold for $5. He sold a total of 20 items and made $76. How many candy bars did Brad sell?

Answers

The answer for the question in this problem would be $12 is the price of candy bars.This is computed by establishing the equation based on the statement, x +y = 20 and 3x + 5y = 76. Follows:

3 (20 - y) +5y = 76
60 - 3y + 5y = 76
2y = 16
y = 8

x = 20 -y
x = 20 - 8
x = 12

Answer:

A: 12

Step-by-step explanation:

The answer for the question in this problem would be $12 is the price of candy bars.This is computed by establishing the equation based on the statement, x +y = 20 and 3x + 5y = 76. Follows:

3 (20 - y) +5y = 76

60 - 3y + 5y = 76

2y = 16

y = 8

x = 20 -y

x = 20 - 8

x = 12

640, 160, 40, 10, ...Which correctly describe the graph of the geometric sequence? Check all that apply.

The graph will show exponential growth.


The graph will appear linear.


The domain will be the set of natural numbers.

The range will be the set of natural numbers.

The graph will show exponential decay.

Answers

Answer:

Option 3 and 5 are correct

Step-by-step explanation:

We have given a geometric series 640,160,40,10....

Common ratio of geometric series is r=(a_2)/(a_1)

r=(160)/(640)=(1)/(4)<0

Here our common ratio is less than zero

It will show the graph of exponential decay

Hence, option 5 is correct.

The general term of geometric series is a_n=a\cdotr^(n-1)

Domain will be all natural numbers since, geometric series take only natural numbers.

Here, values of "n" is domain

Hence, option 3 is correct.

Range can be any positive real numbers  not only natural number

Range is the value of a_n

Hence, option 4 is discarded.

Graph can not be linear of a geometric series being exponential

Hence, option 2 is discarded.

Option 1 is discarded because it is exponential decay function so it can not be exponential growth.

Therefore, Option 3 and 5 are correct.

Answer:

The options that hold true are:

  • The domain will be the set of natural numbers.  
  • The graph will show exponential decay.

Step-by-step explanation:

We are given a geometric sequence as:

                        640, 160, 40, 10, ...  

Clearly we see that each term is decreasing at a constant rate as compared to it's preceding term.

Hence, the graph formed by this sequence will be a  exponential graph with decay .

( since, the terms of the sequence are decreasing)

The sequence could be modeled as:

Let a_n represents the nth term of the sequence.

Hence,

a_n=640\cdot (1)/(4^(n-1))

As, the sequence is geometric hence the domain will be a set of natural numbers.

but the range will be positive real numbers.

Hence, the correct option is:

The domain will be the set of natural numbers.

The graph will show exponential decay
