The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. Ding A single lap should be completed each time you hear this sound. Ding Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, ding

Editors preparing a report on the economy are trying to estimate the percentage of businesses that plan to hire

The number of randomly selected employers that would have to be contacted is 9604

<h3>How to solve for the value of n</h3>

The confidence level is 95%

1 - 0.95 = 0.05

We have to get the z value at 0.05

0.05/2 = 0.025

Using the standard normal table, the critical value at 0.025 = 1.96

We have to define the probability as P = 50% = 0.5

we have to define q = 1 - 50% = 0.5

The formula that would be used to find the value of n is given as

$n = pq\frac{Zc}{E} ^2$

These variables used are:

pq = variance of population

E = margin of error = 0.01

critical value = Zc = 1.96

$n = 0.5*0.5 (\frac{1.96}{0.01})^2$

= 0.25 * 38416

= 9604

Hence the sample space is given as 9604

Phoebe plans to eat out for lunch every day for two weeks, choosing from a row of 9 waterfront restaurants. She promises her bro

sineoko [7]

Phoebe's motion is a "random walk" with a "reflecting barrier." It works out that the expected number of days for Pheobe to end up N positions from her start at one end of the row is N^2. Even if Will adopts the strategy of always eating at the middle restaurant, it may take Phoebe 16 or more days to finally get there if she starts at the end. 16 days is beyond the 2-week time period.

If will goes hunting for Phoebe, there always exists the possibility that she next eats at the restaurant he just left. Will cannot know, for example, that Phoebe will always eat at even numbered restaurants on even days. (She may eat at odd restaurants on those days.) Consequently, he has no basis for narrowing his search.

While I believe eating at the middle restaurant, thus narrowing the possible range of motion of Phoebe, is Will's best strategy, it is certainly not guaranteed to find Phoebe.

Vitek1552 [10]

34 + 5a = 64
5a = 64 - 34
5a = 30
a = 30 ÷ 5
a = 6
