Answer:
38 times
Step-by-step explanation:
A coin has two sides, so there is a 50% chance it will land on either side (assuming perfect conditions and that the coin cannot land vertically). With that in mind, if you flip a coin 76 times, 50% or 1/2 of the times the coin should land on tails. That is 36 times. (Once again, this is under perfect testing conditions. In real life, you probably wouldn't get an even split after only 76 flips.)
Hope this helps :)
Its not linear because growth rates vary with age, gender also plays a role in the change
Answer: $817.50
Step-by-step explanation: i did maths
From secant theorem, 16^2 = 8(12 + y); where y is the missing length of the secant.
256 = 8(12 + y)
12 + y = 32
y = 32 - 12 = 20
From chord theorem, 4x = 4(20)
x = 20
