It means the same used in a question like this, is 25 as much as 25.
The total amount of peaches is 20.
Answer: 2, 9, 14, 17, 19
Step-by-step explanation:
A box plot uses the values: minimum, maximum, median, first quartile and third quartile.
First sort the data from lowest to highest.
2,8,9,11,14,15,17,19,20
Thus, the minimum, or Data Point 1 is 2.
Then find the median.
8,9,11,14,15,17,19
9,11,14,15,17
11,14,15
14
Thus, the median, or Data Point 3 is 14.
For the 1st and 3rd quartile, simply, ignoring the median, find the median of the first and second half of the data.
8,9,11
9
Thus, the first quartile, or Data Point 2 is 9.
15,17,19
17.
Thus, the third quartile, or Data Point 4 is 17.
The maximum of the data, or Data Point 5 is 19.

The Riemann sum with n = 6, taking the sample points to be midpoints is - 12.0625
<h3>What is Riemann sum?</h3>
Formula for midpoints is given as;
M = ∑0^n-1f((xk + xk + 1)/2) × Δx;
From the information given, we have the following parameters
Let' s find the parameters
Δx = (3 - 0)/6 = 0.5
xk = x0 + kΔx = 0.5k
xk+1 = x0 + (k +1)Δx
Substitute the values
= 0 + 0.5(k +1) = 0.5k - 0.5;(xk + xk+1)/2
We then have;
= (0.5k + 0.5k + 05.)/2
= 0.5k + 0.25.
Now f(x) = 2x^2 - 7
Let's find f((xk + xk+1)/2)
Substitute the value of (xk + xk+1)/2)
= f(0.5k+ 0.25)
= 2(0.5k + 0.25)2 - 7
Put values into formula for midpoint
M = ∑05[(0.5k + 0.25)2 - 7] × 0.5.
To evaluate this sum, use command SUM(SEQ) from List menu.
M = - 12.0625
A Riemann sum represents an approximation of a region's area from addition of the areas of multiple simplified slices of the region.
Thus, the Riemann sum with n = 6, taking the sample points to be midpoints is - 12.0625
