Answer:
19.5 miles
Step-by-step explanation:
The question is represented in the image attached.
∠A = 45°, ∠B = 45° + (216° - 180°) = 81°
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
45° + 81° + ∠C = 180°
126 + ∠C = 180
∠C = 180 - 126
∠C = 54°
The sine rule states that for a triangle with sides a, b, c and their corresponding opposite angles A, B and C. The following rule holds:

b = length of beginning of submarine to end point. Using sine rule:

Answer:
Everything except 21/40. That is your ratio. The denominator always
Answer:The correct option is a)
The upper limit of successes that would be deemed to be usual is 5, so more than 5 successes would be unusual.
Step-by-step explanation:
The mean of a binomial distribution
μ= np where n=10 and p= 0.2 q= 1-p, q= 1-0.2=0.8
μ= 10×0.2=2
σ=√npq
σ=√10×0.2×0.8=1.26
Is unusual for the number of success to be greater than μ + 2.5σ.
= 2+2.5(1.26)
=5 approximately.
So it is unusual for it to be greater than 0.5. The right option Is a)
