The Washington Monument in Washington, D.C. is surrounded by a circle of 50 American flags that are each 100 feet from the base of the monument. The distance from the base of a flag pole to the top of the monument is 564 feet. What is the angle of elevation from the base of a flag pole to the top of the monument?
Answers
Answer:
Step-by-step explanation:
cosx=100/564
x=arccos(100/564)
x=79.79 degrees (to the nearest hundredth of a degree)
The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.
Calculation of the angle of elevation;Since there is 100 feet from the base of the monument.
And, The distance from the base of a flag pole to the top of the monument is 564 feet
Now the angle should be like
cosx = 100/564
x = arc cos(100/564)
x=79.79 degrees
hence, The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.

those are currency exchange rates 1 us dollar = 7.76 hk dollars 1 us dollar =1.47 nk dollars work out the value of 1000 hk dollars in nz dollars
Answers
Answer: 1000 HK dollars has the same value as 188.15 NZ dollars.
Step-by-step explanation:
We know that:
1 US dollar = 7.76 HK dollars
1 US dollar = 1.46 NZ dollars.
We have 1000 HK dollars, and we want to know the value in NZ dollars.
First, let's rewrite the 1000 HK dollars in US dollars.
Here we use the relation:
1 US dollar = 7.76 HK dollars
Then:
1 = (1 US dollar/7.76 HK dollars)
Then we can write:
1000 HK = (1000 HK)*1 = (1000 HK)*( (1 US /7.76 HK ))
1000 HK = (1000 HK/7.76 HK)* 1 US = 128.87 US
1000 HK = 128.87 US
Now we can use the relationship:
1 US = 1.46 NZ
Then:
1 = (1.46 NZ)/(1 US)
So we can rewrite:
128.87 US = (128.87 US)*1 = (128.87 US)*( (1.46 NZ)/(1 US))
128.87 US = (128.87 US/1 US)*1.46 NZ = 188.15 NZ
Then:
1000 HK = 128.87 US = 188.15 NZ
So we can conclude that 1000 HK dollars has the same value as 188.15 NZ dollars.

---the system of simoultanious equation
X+2y+z=6
2x+y+2z=6
X+y+z=5
Answers
Answer:
The system of equations has no solution.
Step-by-step explanation:
Let the following system of linear equations:
[tex]x +2\cdot y + z = 6[/tex] (1)
[tex]2\cdot x + y + 2\cdot z = 6[/tex] (2)
[tex]x + y + z = 5[/tex] (3)
Since the quantity of equations and variables are the same, there is only one solution to this system. First, we clear [tex]x[/tex] in (3):
[tex]x = 5 - y - z[/tex]
And make substitution both in (1) and (2):
[tex](5-y-z) +2\cdot y + z = 6[/tex]
[tex]2\cdot (5-y-z)+y+2\cdot z = 6[/tex]
[tex]y = 1[/tex] (4)
[tex]y = 4[/tex] (5)
Which lead to a contradiction, since [tex]4\ne 5[/tex]. Therefore, the system of linear equations has no solution.

A group of veterinary researchers plan a study to estimate the average number of enteroliths in horses suffering from them. Previously research has shown the variability in the number to be σ = 2. The researchers wish the margin of error to be no larger than 0.5 for a 99% confidence interval. To obtain such a margin of error the researchers need at least:
A. 53 observations.
B. 107 observations.
C. 106 observations.
D. 54 observations.
2.
A group of veterinary researchers plan a study to estimate the average number of enteroliths in horses suffering from them. The number of enteroliths is determined by surgery or ultrasound. This requires the participation of a radiologist and a surgeon in the study. The researchers decide that they should only enroll horses seen at the best veterinary hospital in the country to ensure correct counts. Such a hospital will typically see the most severe cases. The researchers will enroll the first 100 horses seen beginning on the day the study is funded. The resulting interval is likely biased because:
A. the first 100 horses seen is not an SRS of all horses with enteroliths and therefore never representative.
B. a sample of 100 horses is too small to obtain an unbiased estimate.
C. the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths.
D. All of the above

This requires the participation of a radiologist and a surgeon in the study. The researchers decide that they should only enroll horses seen at the best veterinary hospital in the country to ensure correct counts. Such a hospital will typically see the most severe cases. The researchers will enroll the first 20 horses seen beginning on the day the study is funded. The researchers will calculate a 95% confidence interval. The procedure is not valid because the:
A. sample size is too small for the central limit theorem to apply.
B. average number is not an integer and does not reflect any actual observation.
C. None of the above. The procedure is valid.
D. data are counts and, therefore, not Normally distributed.
4.
In a test of hypothesis for a mean, which statement is CORRECT?
A. The test requires that the sample mean is normally distributed; this requires that either the population distribution is Normal or the sample size exceeds 30.
B. As long as the population distribution consists only of positive values, sample size does not matter.
C. The population distribution can be any distribution because the sample mean is always Normally distributed.

A. a Type I error.
B. the power of the test.
C. a Type II error.
D. None of the above
Answers
Answer:
1.) 107 observations
2.) the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths
3.) A. sample size is too small for the central limit theorem to apply.
4.) The test requires that the sample mean is normally distributed; this requires that either the population distribution is Normal or the sample size exceeds 30.
5.) a Type I error
Step-by-step explanation:
n = [(Zcritical * σ) ÷ E]²
n = sample size
Zcritical at 99% = 2.58
E = error margin = 0.5
Standard deviation, σ = 2
n = [(2.58 * 2) ÷ 0.5]²
n = [5.16 ÷ 0.5]²
n = (10.32)²
n = 106.5024
n = 107 observations
B.) The thought or decision that the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths will introduce a bias in the study.
C.) For central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30
D.) Distribution must be normal it approximately normal, obeying the central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30
For f (x) = 2x+1 and g(x) = x2 - 7, find (fºg)(2).
Answers
Answer:
Step-by-step explanation:
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8
