Tossing a coin is a binomial experiment.
Now lets say there are 'n' repeated trials to get heads. Each of the trials can result in either a head or a tail.
All of these trials are independent since the result of one trial does not affect the result of the next trial.
Now, for 'n' repeated trials the total number of successes is given by
where 'r' denotes the number of successful results.
In our case 
and 
,
Substituting the values we get,
Therefore, there are 1352078 ways to get heads if a person tosses a coin 23 times.

Step-by-step explanation:
Answer:
Step-by-step explanation:
To calculate the weighted moving average for period 13 with weights 0.4 and 0.3.
P13 = (30.7x 0.4) + (42.0x 0.3)
P13 = 12.28 + 12.60
P13 = 24.88
Answer:
d-5=2s
Step-by-step explanation:
Diego's age d is 5 more than 2 times his sister's age s.
The equation used to represent it is :
d = 2s +5
We need to find the equivalent equation for the above equation.
If we take 5 to LHS of the equation, it will become -5 such that,
d-5=2s
Hence, option (b) is the equivalent equation.
The value of the 2 in the thousands place is 10 times the value of 2 in the hundreds place.
200 x 10 = 2000
