<span>6 km × 1 hour/(b-4 km) = 12 km × (1 hour/(b+4 km)
6/(b-4) hours = 12/(b+4) hours
6(b+4) = 12(b-4)
6b + 24 = 12b - 48
72 = 6b
b = 12
The boat's speed in still water is 12 km/hour.</span>

Answer:
<em>The probability that a randomly selected government worker witnessed a violation of ethical standards, policies or laws in the past year but did not report it is </em><em>0.3</em>
Step-by-step explanation:
The outcome of the Washington- based nonprofit research group are that -
- P (60) -60% of government workers acknowledge witnessing violations of ethical standards, policies, or laws in the past year;
- P (40%) - of which went unreported.
- P (10) - An additional 10% of government workers acknowledged making false reports of violations of ethical standards, policies or laws when they did not actually occur.
∴ P(60%) + P(10%) = P(70) which is Probability of those that are involved in one form of violations or the other.
Therefore, P(100%) - P(70%) = 30%
P( Not committed and withnessed any violations of ethical standards, policie or law) = 30%/100%
<em>= 0.3</em>
Answer:
Length = 502 ft
Width = 212 ft
Step-by-step explanation:
Recall the formula for the perimeter of a rectangle of length "L" and width "W":
Perimeter = 2 L + 2 W = 1428 ft
Now, since the length is 78 ft more than twice the width, then we can write this in mathematical form as:
L = 2 W +78
so, 2 W = L -7 8
and now replace "2 W" with it equivalent "L - 78" in the first perimeter equation and solve for "L":
2 L + L - 78 = 1428
3 L = 1428 + 78
3 L = 1506
L = 1506/3
L = 502 ft
Then the width W can be obtained via:
2 W = L - 78
2 w = 502 -78
2 W = 424
w = 212 ft
