Answer:
x = 2π3
Step-by-step explanation:
csc(x)csc(x) , x=πx=π
3x+2y+zx+y+z3x+2y+zx+y+z , x=2x=2 , y=3y=3 , z=1z=1
cot(3x)cot(3x) , x=2π3
Hope this helps :)
Answer:
a. 19.68 miles per gallon.
b. 26.32 miles per gallon.
Step-by-step explanation:
Mean gas mileage (μ) = 23.0 mpg
Standard deviation (σ) = 4.9 mpg
In a normal distribution, for any length X, the z-score is determined by the following expression:
In a normal distribution, the 25th percentile (first quartile) of a normal distribution has a corresponding z-score of z = -0.677 and the 75th percentile has a corresponding z-score of z = 0.677
a. The first quartile of the distribution of gas mileage is
19.68 miles per gallon.
b. The third quartile of the distribution of gas mileage is
26.32 miles per gallon.

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>
