A researcher tagged 40 giant turtles in 2008. In 2009 , she returned and captured 50 turtles , 16 of which were tagged. In 2010 , she returned again and captured 30 turtles , 8 of which were tagged.
a) Use a proportion to estimate the turtle population for 2009.
b) Use a proportion to estimate the turtle population for 2010.
We know that there are 40 turtles tagged.
In 2009, 16/50 = 32% of the population was tagged, making the population 40/.32 = 125 (P/40 = 50/16)
In 2010, 8/30 = 26.7% of the population was tagged. So, the population is about 150 (P/40 = 30/8)
Guys don't use answers because all math test are different
the tests do change don't listen to him
anything? ( ͡° ͜ʖ ͡°)
please do not like this comment.
please and thank you.
Anyways,
The answers changes on test.
anything else it dosen't change.
Like on quick checks, it dosen't
change
They change the test dummys
actually yes they changed all the unit tests two years ago so 2018 and lower are all false
what are the answers bruh we didn’t come here to play around some of us actually want a future.
thanks

help me plz i will do anything if u help me plz
A: 2009, 16/50 = 32% of the poplation was tagged, making the poplation 40/.30 = 125.
B: 2010, 8/30 = 26.7% of the poplation was tagged. Poplation is about 150.
(T-T)
yall act like kids we need the answers not "The capital I, is thicker" i mean like come on really
For 2009:
Number of tagged turtles in 2009 = 16
Total number of turtles captured in 2009 = 50
The proportion of tagged turtles to the total turtle population is:
16/50 = 0.32
So, the population of turtles in 2009 is:
40/0.32 = 125 turtles
For 2010:
Number of tagged turtles in 2010 = 8
Total number of turtles captured in 2010 = 30
The proportion of tagged turtles to the total turtle population is:
8/30 = 0.2667
So, the population of turtles in 2010 is:
40/0.2667 = 150 turtles
is steve right?
Just saying, you can see the difference between
Heiio and Hello right? with two capital I's it'd look like this HeIIo.

To find the mean:
Add up all the scores and divide by the total number of scores.
Mean = (86 + 75 + 97 + 58 + 94 + 58) / 6
Mean = 78
To find the median:
Put the scores in order from least to greatest and find the middle score. If there are two middle scores, find the average of the two.
Ordering the scores gives: 58, 58, 75, 86, 94, 97
Median = (75 + 86) / 2
Median = 80.5
To find the mode:
The mode is the most frequent score in the set.
Mode = 58
Based on the scores, the teacher should use the mean to convince Maria that she needs to study more regularly for her exams, as the mean score is significantly lower than the other scores and suggests a need for improvement.
a) To estimate the turtle population for 2009 using proportion, we can set up the proportion of tagged turtles in 2009 to the total turtle population as follows:
tagged turtles/total population = tagged turtles in sample/total turtles in sample
Solving for the total population gives:
total population = (tagged turtles/total turtles in sample) x (total turtles in sample)
In 2009, 16 out of 50 turtles were tagged. Therefore,
total population in 2009 = (40/16) x 50 = 125
Hence, we can estimate that the turtle population was 125 in 2009.
b) Similarly, to estimate the turtle population for 2010 using proportion, we can set up the proportion of tagged turtles in 2010 to the total turtle population as follows:
tagged turtles/total population = tagged turtles in sample/total turtles in sample
Solving for the total population gives:
total population = (tagged turtles/total turtles in sample) x (total turtles in sample)
In 2010, 8 out of 30 turtles were tagged. Therefore,
total population in 2010 = (40/8) x 30 = 150
Hence, we can estimate that the turtle population was 150 in 2010.
oh yeah he is

HeIIo
HAHA YOU FOOLS I DID Heiio with 2 capital i's
Mean and MAD of soil A:
Mean:
We need to convert the stem-and-leaf plot to raw data in order to find the mean. The raw data for soil A is: 120, 121, 125, 130, 137, 138, 139, 150, 151, 152, 160, 160, 160, 160, 160, 160, 161, 162, 165, 169, 170, 175, 180
To find the mean, we add up all the values and divide by the number of values:
Mean = (120 + 121 + 125 + 130 + 137 + 138 + 139 + 150 + 151 + 152 + 160 + 160 + 160 + 160 + 160 + 160 + 161 + 162 + 165 + 169 + 170 + 175 + 180) / 23
Mean ≈ 153.87
MAD:
To find the MAD, we first need to find the deviation of each value from the mean. We can calculate the deviation by subtracting the mean from each value in the data set:
Deviation = |Value - Mean|
Using the mean we calculated above:
Deviation = |120 - 153.87| = 33.87
Deviation = |121 - 153.87| = 32.87
Deviation = |125 - 153.87| = 28.87
Deviation = |130 - 153.87| = 23.87
Deviation = |137 - 153.87| = 16.87
Deviation = |138 - 153.87| = 15.87
Deviation = |139 - 153.87| = 14.87
Deviation = |150 - 153.87| = 3.87
Deviation = |151 - 153.87| = 2.87
Deviation = |152 - 153.87| = 1.87
Deviation = |160 - 153.87| = 6.13
Deviation = |160 - 153.87| = 6.13
Deviation = |160 - 153.87| = 6.13
Deviation = |160 - 153.87| = 6.13
Deviation = |160 - 153.87| = 6.13
Deviation = |160 - 153.87| = 6.13
Deviation = |161 - 153.87| = 7.13
Deviation = |162 - 153.87| = 8.13
Deviation = |165 - 153.87| = 11.13
Deviation = |169 - 153.87| = 15.13
Deviation = |170 - 153.87| = 16.13
Deviation = |175 - 153.87| = 21.13
Deviation = |180 - 153.87| = 26.13
To find the MAD, we take the mean of the absolute deviations:
MAD = (33.87 + 32.87 + 28.87 + 23.87 + 16.87 + 15.87 + 14.87 + 3.87 + 2.87 + 1.87 + 6.13 + 6.13 + 6.13 + 6.13 + 6.13 + 6.13 + 7.13 + 8.13 + 11.13 + 15.13 + 16.13 + 21.13 + 26.13) / 23
MAD ≈ 12.61
Mean and MAD of soil B:
Mean:
The raw data for soil B is: 58, 59, 63, 67, 80, 83, 89
Mean = (58 + 59 + 63 + 67 + 80 + 83 + 89) / 7
Mean = 70
MAD:
Deviation = |Value - Mean|
Deviation = |58 - 70| = 12
Deviation = |59 - 70| = 11
Deviation = |63 - 70| = 7
Deviation = |67 - 70| = 3
Deviation = |80 - 70| = 10
Deviation = |83 - 70| = 13
Deviation = |89 - 70| = 19
MAD = (12 + 11 + 7 + 3 + 10 + 13 + 19) / 7
MAD ≈ 10.14
Which set is more variable? How do you know?
Soil A has a higher MAD (12.61) compared to soil B (10.14), so it is more variable. This suggests that the data points in soil A are more spread out from the mean compared to soil B, which has a smaller range of values.
