Answer:
3:15 pm
Step-by-step explanation:
You can imagine that they go in a circle (we can do whatever we want in theoretical math and physics). By doing so we know we can obtain a cosinusoidal wave by projecting the motion on a plane. Each one of the buses has a period (minimum time after what they're in the same point again). For the first one it's 15 minutes, for the second one it's 20 minutes. We have to take the least common multiple of the periods, that is 75 minutes. So They'll meet every 75 minutes. Add 75 minutes (1h and 15 minutes) to 2pm and there you go.
The pressure at a certain height is the pressure at sea level plus the hydrostatic pressure.
P = 80 psi + ΔP
where
ΔP = ρgh
ρ is the density of water equal to 62.4 lbm/ft³
ΔP = (62.4 lbm/ft³)(1 lbf/lbm)(4*10 + 2 ft)(1 ft/12 in)² = 18.2 psi
Thus,
P = 80 + 18.2
<em>P = 98.2 psi</em>
The height of the deck if it is parallelogram H ≈ 6.13
|-7| - 7 = 0
2|-7| = 14
(-7)^2 = 49
-7^2 = 49
-7 -|-7| =-14
Answer:
Step-by-step explanation:
Problem 6-01 (Algorithmic) Consider the following time series data. Week 1 2 3 4 5 6 Value 20 13 15 11 17 14 Using the naïve method (most recent value) as the forecast for the next week, compute the following measures of forecast accuracy. Mean absolute error. If required, round your answer to one decimal place. Mean squared error. If required, round your answer to one decimal place. Mean absolute percentage error. If required, round your intermediate calculations and final answer to two decimal places. % What is the forecast for week 7? If required, round your answer to two decimal place.
