The error bars are used to indicate the variability of the data presented in a graph.
There are several quantities that can be used to generate error bars in the graph. These are:
standard deviation
standard error
confidence interval
Usually, one standard deviation above and below the mean is used although it is advised to indicate which variability data is used to generate the error bars in the graph since the 3 quantity given are not equal.
Answer:
Step-by-step explanation:
<u>Key skills: Exponents + Fractions</u>
Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y
3^-4 is the same as 
3^4 is 81, so your answer would be 1/81.
Hope you have a nice day and understood this!
Answer:
Hence the 3.28 %or 2/61 of total work will be done .
Step-by-step explanation:
Given:
The pecan crops are harvested for friday and saturday (2days)
To find :
What fraction these 2 days corresponds to the harvesting days?
Solution;
The pecan crops are growing in America in state of Georgia
and consider that in months of October and November pecan crop becomes mature .
Hence the harvesting period is of 2 months considerably .
The month of October and November days are 31 and 30 .
Hence the Total days of harvesting are 61 days.
In these days total Pecan crops will be harvested.(100% work in 61 days)
Now the farmer harvest for 2 days only .
Required fraction=2/61
=0.0327869
=3.28%
Depending upon the crop field and planting answer will vary
But 3.28 % of total work will be done in 2 days on harvesting
3x * 3x = 9x
9x + 6 - 2x + 5x - 4x^2 + 9
9x + 6 - 7x - 4x * 4x + 9
9x + 6 - 7x - 16x + 9
9x + -7x = 2x + 6 - 16x + 9
2x + 6 - 16x + 9
2x + (-3) - 16x
-14x + (-3) is the expression?
