I did the work and solved it
Step-by-step explanation:
Arthur got because a pizza is shared by 4 people. however only
2/3 of the pizza is there so it is divided by the four people.
So, if the jar has 20 yellow marbles, 55 green marbles, and 25 purple marbles in total it has 100 marbles. (check:20+55+25=100m). Sense there are 55 green marbles out of 100, your theoretical probability will be 550/100(fraction:55 over 100). Simplified its 11/20.
Answer:
Actual mean: 223 pages
Predicted mean / estimate: 225 pages
Explanation below
Step-by-step explanation:
Mean = total amount ÷ # of numbers
155 + 214 + 312 + 198 + 200 + 170 + 250 + 260 + 215 + 256
Add
2,230
# of numbers = 10
2,230 ÷ 10 = 223
The exact mean is 223
If I were to predict the mean, I would say that a good estimation would be around 225, because I see that the highest number in the data set is 312, and the lowest is 155. If 312 is rounded down to 300, and 155 is rounded down to 150, the number exactly in the middle of 300 and 150 is 225.
Actual mean: 223 pages
Predicted mean: 225 pages
Hope this helps :)
In a nutshell, the Riemann's sum that represents the <em>linear</em> equation is A ≈ [[4 - (- 6)] / 5] · ∑ 2 [- 6 + i · [[4 - (- 6)] / 5]] - [[4 - (- 6)] / 5], for i ∈ {1, 2, 3, 4, 5}, whose picture is located in the lower left corner of the image.
<h3>How to determine the approximate area of a definite integral by Riemann's sum with right endpoints</h3>
Riemann's sums represent the sum of a <em>finite</em> number of rectangles of <em>same</em> width and with <em>excess</em> area for y > 0 and <em>truncated</em> area for y < 0, both generated with respect to the <em>"horizontal"</em> axis (x-axis). This form of Riemann's sum is described by the following expression:
A ≈ [(b - a) / n] · ∑ f[a + i · [(b - a) / n]], for i ∈ {1, 2, 3, ..., n}
Where:
- a - Lower limit
- b - Upper limit
- n - Number of rectangle of equal width.
- i - Index of the i-th rectangle.
Then, the equation that represents the <em>approximate</em> area of the curve is: (f(x) = 2 · x - 1, a = - 6, b = 4, n = 5)
A ≈ [[4 - (- 6)] / 5] · ∑ 2 [- 6 + i · [[4 - (- 6)] / 5]] - [[4 - (- 6)] / 5], for i ∈ {1, 2, 3, 4, 5}
