Answer:
C.
Step-by-step explanation:
Given,
Initial distance Marika covered = 100 yards,
Also, She gradually increases her distance by 4 yards,
Thus, the difference between the distance of consecutive days is 4 yards,
So, there is an AP that shows the given situation,
Having first term, a = 100,
Common difference, d = 4,
Since, the explicit formula of an AP is,
Which is the required formula.
Option 'C' is correct.

Answer:
In order to establishing the success of the method we need to obtain a p value very low in order to reject the null hypothesis because we need enough evidence in favor of the alternative hypothesis, so then the best option would be:
f. 0.001
Step-by-step explanation:
We need to conduct a hypothesis in order to test the claim that one of several methods claimed to increase the likelihood of a baby girl so then the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statisitc, and the is given by:
(1)
The p value for this case is given by:
In order to establishing the success of the method we need to obtain a p value very low in order to reject the null hypothesis because we need enough evidence in favor of the alternative hypothesis, so then the best option would be:
f. 0.001
