At day 7, the four-day moving average for the price of the stock would be $58.25.
<h3>What is the four-day moving average at day 7?</h3>
This can be found as:
= (Day 7 price + Day 6 + Day 5 + Day 4) / Number of days
Solving gives:
= (59 + 55 + 59 + 60) / 4
= 233 / 4
= $58.25

Im not sure what you are asking, but for a probability tree, you have the total # of something at the very top of the tree, next it branches out into groups, and those groups represent something like colored marbles or something... and to find percent you divide the total number like the number of marbles bye 100 and multiply that number bye the thing that you're trying to get job percent like a color of marbles, I hope this helped...

Answer:
yes
Step-by-step explanation:
You can go at this a couple of ways:
1. The total length David needs is (1.75 m) × 4 = 7.00 m. His 7.28 m piece is long enough to provide the pieces he needs.
__
2. The length of each piece when the wood is cut into quarters is ...
(7.28 m)/4 = 1.82 m
This is longer than the 1.75 m needed, so each piece is long enough.
In triangle, ABD,
AD²= AB²+BD²
AB² = AD²-BD²
AB² = 18²-9² = 324-81 = 243
AB = √243
In triangle, ABC,
AC² = AB²+BC²
AC² = (√243)²+(13)²
AC² = 243+169
AC = √412
AC = 20.29
