Answer:
4.results should be reported with some measure that represent how convinced we are that our conclusion reflect reality
Step-by-step explanation:
Certainly statistics deals with organization, evaluation and data conclusions. But the data is always obtained from representative samples of certain universes for that reason those results must be associated with the degree of confidence
The easiest way to do this is to add or subtract the value of the variable.
For example in the equation 5+a=7, subtract a from both sides to get 5=7-a.
If the initial equation was 5-a=7, add from both sides (5=a+7).
Basically, if the initial value is negative, add its value to cancel to zero.
Do the opposite if the initial value is positive.
Method 1:
Look at the picture.
is greater than ![\dfrac{1}{9}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B9%7D)
![\boxed{\dfrac{1}{7}>\dfrac{1}{9}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cdfrac%7B1%7D%7B7%7D%3E%5Cdfrac%7B1%7D%7B9%7D%7D)
Method 2:
Find the common denominator:
multiples of 7: 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ...
multiples of 9: 0, 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...
63 = 7 · 9
![\dfrac{1}{7}=\dfrac{1\cdot9}{7\cdot9}=\dfrac{9}{63}\\\\\dfrac{1}{9}=\dfrac{1\cdot7}{9\cdot7}=\dfrac{7}{63}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B7%7D%3D%5Cdfrac%7B1%5Ccdot9%7D%7B7%5Ccdot9%7D%3D%5Cdfrac%7B9%7D%7B63%7D%5C%5C%5C%5C%5Cdfrac%7B1%7D%7B9%7D%3D%5Cdfrac%7B1%5Ccdot7%7D%7B9%5Ccdot7%7D%3D%5Cdfrac%7B7%7D%7B63%7D)
![\dfrac{9}{63} > \dfrac{7}{63}](https://tex.z-dn.net/?f=%5Cdfrac%7B9%7D%7B63%7D%20%3E%20%5Cdfrac%7B7%7D%7B63%7D)
therefore
![\dfrac{1}{7} > \dfrac{1}{9}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B7%7D%20%3E%20%5Cdfrac%7B1%7D%7B9%7D)
You have to test dp/dt between these intervals
(-inf,2)
(2,10)
(10,inf)
if dp/dt is positive then the population is increasing with respect to time in that interval
Answer:
Sorry. Don't have a way to plot it then show you .The Y intercept is 4. The slope is -3x which means its decreasing. Hope this helps
