Basically, we are trying to find the third number in the pattern. The pattern is - -4, -2, -12, -14 and so on. We can see that the third number is -12, which is a₃. Therefore, the answer is C) -12. Hope this helped!
A suitable probability calculator will show that probability to be .135905122.
_____
Your class extends from 1 standard deviation above the mean to 2 standard deviations above the mean. The empirical rule puts that probability at ...
... (1/2)(95% - 68%) ≈ 13.5%
The empirical rule tells you 68% of observations lie within 1 standard deviation of the mean, and 95% lie within 2 standard deviations. Then the number that lie between 1 and 2 standard deviations from the mean will be the difference of these values. You want the values in the region above the mean only, so you only want half the difference just described.
Answer:
The farmer should expect to LOSE 10 pounds of soybeans per acre per year
Step-by-step explanation:
f(x)=-x^2 + 20x + 100
just find how many soybeans his land will yield (per acre) after 10 and 20 years:
After 10: 200 pounds of soybeans/acre
After 20: 100 pounds of soybeans/acre
Because 10 years have passed and they lost 100 pounds of soybean production per acre, the farmer should expect to lose 10 pounds of soybeans per acre per year (-10 pounds of soybeans per acre/year)

Answer:
6.30$
Step-by-step explanation:
If you add 7.80$ and 7.80$ that come to 4 hot dogs,
The rest of the money is how much one soda cost ( 2.40$ ),
Dividing that 7.80$ by 2, To only have one hot dog, would put you at
3.90$ fro one hot dog, then all you have to do is add them together, to get the total of 6.30
7.80 | 17.00 | 7.80/2 | 2.40
+ 7.80 | - 15.60 | 3.90 | + 3.90
15.60 | 2.40 | | 6.30
