Answer:
You can find the answer by using the formula t=-b/2a
Step-by-step explanation:
Remember the maximum height will be at the vertex. The x value of the vertex is your time, so use x=-b/2a except that t is your x. Then if it had also asked what the height was, you would plug that answer into your equation to find the y value of the vertex. Pretty sure your teacher is just asking you to find the x though:)
Answer:
Option a) 1.6 .
Step-by-step explanation:
We are given that 142 subjects were treated with acupuncture. The numbers of migraine attacks for the treatment group had a mean of 1.8 and a standard deviation of 1.4 which means;
Sample Mean, = 1.8 , Sample standard deviation, s = 1.4 and Sample size = 142.
Now, 95% confidence interval estimate of the mean number of migraine attacks for all people treated with acupuncture is given by;
⇒
So, the lower bound = = 1.56 ≈ 1.6
Therefore, option A is correct.
