Answer:
0.0433
Step-by-step explanation:
Since we have a fixed number of trials (N = 25) and the probability of getting heads is always p = 0.05, we are going to treat this as a binomial distribution.
Using a binomial probability calculator, we find that the probability of obtaining heads from 8 to 17 times is 0.9567 given that the con is fair. The probability of obtaining any other value given that the coin is fair is going to be:
1 - 0.9567 = 0.0433
Since we are going to conclude that the coin is baised if either x<8 or x>17, the probability of judging the coin to be baised when it is actually fair is 4.33%
Answer:
x = -8
Step-by-step explanation:
Set the function f(x)=9-2x equal to 25, and then solve the resulting equation for x:
9 - 2x = 25.
Isolate the -2x term by subracting 9 from both sides:
-2x = 16
Finally, solve for x by dividing both sides by -2:
x = -16/2, or x = -8

Answer:
Step-by-step explanation:
Width = x
Length = 2x
Area of the ground = 0.125 square mile
length * width = 0.125
2x * x = 0.125
2x² = 0.125
x² = 
= 0.0625
Width = 0.25 miles
Length = 2* 0.25 = 0.50 miles
