Answer:
Step-by-step explanation:
We want to find the Riemann sum for with n = 6, using left endpoints.
The Left Riemann Sum uses the left endpoints of a sub-interval:
where .
Step 1: Find
We have that
Therefore,
Step 2: Divide the interval into n = 6 sub-intervals of length
Step 3: Evaluate the function at the left endpoints
Step 4: Apply the Left Riemann Sum formula
Answer:
a) All the phones produced during the day in question.
Step-by-step explanation:
In statistics, the Population is all the objects with the same characteristics in which we have an interest in doing an experiment or statistical analysis. Sometimes to make it more simple, we take just a sample of the population and we do the experiments with them, and then the answers are used to all of the objects.
In this case, they want to analyze all the cellphones but they only take a few to do it. So the answer is a) All the phones produced during the day in question.
You can use Soh Cah Toa to get your answer, in other words, sin cos tan. If you already have x, that means you probably used tan, which is adjacent and opposite. Now for y, you are trying to find the hypotenuse so you could use, sin or cos, for sin you would use the adjacent (x) and the hypotenuse (y) and for cos, you would use opposite (4) and the hypotenuse (y). This is all based on the angle 45.
The first one, 4x is the slope and the +3 is the y-intercept
