Answer:
The correct answer is option b. Sin or csc
Step-by-step explanation:
<u>Trigonometric ratios</u>
Sinθ = Opposite side/Hypotenuse, Cosec = 1/Sinθ
Cosθ = Opposite side/Hypotenuse , Secθ = 1/cosθ
Tan θ = Opposite side/Adjacent side, cotθ = 1/Tan θ
From the figure we can see a right angled triangle RST,
Right angled at R
<u> To find the value of TS</u>
We have m< S=27º and TR=7
Sin S = TR/TS
TS = Sin S * TR
Cosec = 1/Sinθ
Therefore the correct answer is option b

Answer:
Variance = 24900
Standard Deviation = 157.7973
Step-by-step explanation:
We are given the following in the question:
Number of admissions: 1000 1200 1500
Admissions Probability: 0.6 0.3 0.1
Formula:
Variance =
Thus, the variance is 24900.
Standard Deviation =
Thus, the standard deviation is 157.7973
Answer:
h = 2
Step-by-step explanation:
Assuming that the line in the middle of the triangle is divided in half. You would need to use the Pythagorean theorem to get the height.
If the bottom is 5m and the hypotenuse is 7m, plug these numbers in to get this equation h^2 + 5^2 = 7^2. 5^2 is 25 and 7^2 is 49. Subtract 25 on both sides to get h^2 = 24. Radicals are there so you would need to think of 4 and 6 to get 2 since there are 2 of to make 2 and that left us with root 6 which is your final answer for the height.
