Answer: 64% of garbage was plastic over there when he was collected garbage.

Step-by-step explanation:

Since we have given that

Total amount of garbage collected by them = 25 pounds

Total amount of garbage which consisted of plastic = 16 pounds

Percent of the garbage was garbage is given by

\frac{ plastic}{total}\times 100

=\frac{16}{25}\times 100\\\\=16\times 4\\\\=64

Hence, 64% of garbage was plastic over there when he was collected garbage.

Answer:

64%.

Step-by-step explanation:

We are told that in an ocean cleanup we collected a total of 25 pounds of garbage and 16 pounds of the garbage consisted of plastic. We are asked to find out what percent of the garbage was plastic .

We can set an equation to find out our percentage as:

\frac{16}{25} *100

0.64*100

64%

Therefore, 64% of the garbage was plastic.

Is the data set approximately periodic?
wolverine [178]

Answer:

Option: C is the correct answer.

       C. Periodic with period 4 and amplitude of about 15.

Step-by-step explanation:

We are given the table of values as:

Hour             1 -- 2 -- 3 --  4 --  5 -- 6 -- 7 -- 8 -- 9 -- 10 -- 11

Number       24-41-10-32-26-38-9-31-25-39-12

of boats

As we could see that after every 4 value the values are approximately repeating.

Hence,the data set is approximately periodic.

Also, the amplitude is calculated as:

Average of the maximum and minimum value of each set

We divide the set into 3 sets as follows:

 Hour                       1           2           3            4

Number of boat      24        41          10           32

Here we have amplitude as:

         (41-10)/2=15.5

 Hour                       5           6           7            8

Number of boat      26        38           9           31

  Amplitude is:

          (38-9)/2=14.5

Hour                       9           10          11            12

Number of boat      25        39          12      

            Amplitude is:

            (39-12)/2=13.5

Hence, we see that the amplitude is about 15.

Makovka662 [10]

Answer:

Month 1 : 0.002988

Month 2: 0.00299692814

Month 3: 0.00300588297

Step-by-step explanation:

Since we're only finding the interest for the first three months, it's easy to do it by performing the simple interest formula. But first, we need divide 3 by 12, since we calculate interest using years. 3/12 = 1/4 = 0.25

The standard simple interest calculation is done by multiplying the starting amount, by the interest, by the time, then dividing by 100 to put it into a percentage.

1 month = 1/12 or approximately 0.083 of the year.

Let's say P = 1. For the first month, it will be 1 x 3.6 x 0.083 = 0.2988 / 100

The second month, (1 + 0.002988) * 3.6 * 0.083 = 0.299692814 / 100

The third month, (1.002988 + 0.00299692814) x 3.6 x 0.083 = 0.300588297/100

Given the initial amount be 1, those would be the periodic interest rate during the first three months.
