Answer:
No
Explanation:
51 / 100 = 510 / 1000
Chance of getting a head is 1 / 2 of total throws
= 1 / 2 × 1000
= 500 is the probability
and the number of heads was just 10 more the the probability...if the was a greater gap, there would be evidence to say the coin is unfair

Detailed solution is attached in the images below showing step wise solution and answer for each part individually.
It can provide measurements of stars with a higher angular resolution than is possible with conventional telescopes.
Answer:
Time of submersion in years = 7.71 years
Explanation:
Area of plate (A)= 16in²
Mass corroded away = Weight Loss (W) = 3.2 kg = 3.2 x 106
Corrosion Penetration Rate (CPR) = 200mpy
Density of steel (D) = 7.9g/cm³
Constant = 534
The expression for the corrosion penetration rate is
Corrosion Penetration Rate = Constant x Total Weight Loss/Time taken for Weight Loss x Exposed Surface Area x Density of the Metal
Re- arrange the equation for time taken
T = k x W/ A x CPR x D
T = (534 x 3.2 x 106)/(16 x 7.9 x 200)
T = 67594.93 hours
Convert hours into years by
T = 67594.93 x (1year/365 days x 24 hours x 1 day)
T = 7.71 years
