Answer:
Step-by-step explanation:
1. sinФ = cos 25
25 ° is in the between 0 and 90°
therefore it can simply represent
cosФ= sin (90-Ф) = sin (90 - 25) = sin 65
2. sin(Ф/3 + 10) = cos Ф
cos Ф = sin (90 -Ф)
sin(Ф/3 + 10) = cos Ф
sin(Ф/3 + 10) = cos Ф = sin(90-Ф)
Ф/3+10=90-Ф
10Ф+3/30 = 90-Ф
10Ф+3 = 30(90-Ф)
10Ф+3 = 2700-30Ф
10Ф+30Ф=2700-3
40Ф = 2697
Ф = 2697 / 40 = 67.425 ≅ 67.4°
180°=triangle
360°=quadrangle
180°*34+180=6300°
Answer:
C with 3000 successes of 5000 cases
Step-by-step explanation:
In test statistics the number of samples goes a long way in determining the result of a test.
Using the z score formula
Test statistic z score can be calculated with the formula below;
z = (p^−po)/√{po(1−po)/n}
Where,
z= Test statistics
n = Sample size
po = Null hypothesized value
p^ = Observed proportion
Therefore the z score is directly proportional to the square root of the sample size.
z ∝ √n
The higher the sample size, the higher the z score, the higher the evidence of confirming the alternative hypothesis.
Since the all have the same proportion (0.6), and options c has the highest sample size (5000 cases), it will give the strongest evidence for the alternative hypothesis
Answer: 
Step-by-step explanation:
For this exercise you must use the followinG Trigonometric Identity:
In this case, given the right triangle PQR, you can identify that:
Then, the next step is to substitute those values into :
And the final step is to solve for "QR" in order to find its value.
So you get that this is:
