- 10:24 “So therefore, summation f x equals 84, y summation f equals 30. So we have mean x bar to be 84, all over 30. And that will give us 2.8. When we are going to the nearest one number, we have 3. So therefore, what mean x ba...”
- 04:46 “We first of all, and you know the formula for that. That is summation x all over n. So we had all this, and that is 18 plus 20 plus 25 plus 30 plus 22 plus 25 plus 28 plus 15. We all over the number of data, that is the...”
- 07:15 “when arranging it in ascending order. You are going to have the two number and divide it by two. That is, 22, all of us 25, I mean 22 plus 25, all of us two. And that would give us 47, all of us two. And that is 23.5. Ap...”
Cost of Production
This lesson covers the concept of cost in economics, focusing on the cost of production. It explains different types of costs, such as fixed and variable costs, and discusses the factors of production that contribute to overall costs.
- 23:32 “variable cost, is that a so, now if you look at this table, is there fixed cost, no, is there variable cost, no, this missing formula cannot work, so you need to think of another approach that you can use, please this is...”
- 17:46 “okay, is your worth, is your total cost, the combination of fixed cost and variable cost, is not worth that, so without wasting time, let's move to the next one, and this is average cost, average cost, when we say averag...”
- 24:19 “multiply by words, the quantity, the quantity is the same thing as the output, so it trades it to your A, okay, trades it to your A, what do you have, three, so six times three, give us what, 18, and that's how you have...”
