Answer:
0.075 inches per year
Step-by-step explanation:
The average rate of change is measured as
( difference in diameter ) ÷ ( difference in years )
= ( 251 - 248 ) ÷ ( 2005 - 1965 )
= 3 inches ÷ 40 years
= 0.075 inches per year
The estimated answer is 11. First you round 16.8 to 17 because the decimal is above 5. Then you round 5.94 to 6 because the first decimal place is greater than 5. Lastly you subtract 17 minus 5 to get 11.
Answer: D. History
Step-by-step explanation:
To answer this question, we need to use the z-score formula written below:
![\frac{x-pop. mean}{stan. devi.}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-pop.%20mean%7D%7Bstan.%20devi.%7D)
Now we'll just plug in the numbers and solve.
History:
![\frac{85-65}{5} = 4](https://tex.z-dn.net/?f=%5Cfrac%7B85-65%7D%7B5%7D%20%20%3D%204)
Biology:
![\frac{90-85}{10} =0.5](https://tex.z-dn.net/?f=%5Cfrac%7B90-85%7D%7B10%7D%20%3D0.5)
As we can see, history wields a higher z-score than biology, thus leaving us with option D. History
