Answer: D. Simple Random Sampling
Step-by-step explanation: When selection is made or based on chance which is equal or the same for all members within a population. In the scenario described above, there is no prior shuffling, arrangement or segregation of members within the population into groups or subgroups, rather the interviewed voters were chosen at random directly from within the larger population based on equal chance. Therefore voters already have their numbers, then using a random number generator, voters whose number corresponds were interviewed is a clear scenario of simple Random Sampling.
Step-by-step explanation:
The derivative of log is
You can easily derive this using the Change of base rule, and natural log rules
Next, we differentiate with respect to x.
So back to the topic at hand,.
a=7, so we get
We plug in 0, we would get undefined
A. 19. You have to set them up equal to each other. So, 6x-2=4x+36. You then subtract the 4x from the 6x, and add 2 to 36. Which leaves you with 2x=38. Divide and you get 19! Hope this helps
