Walking directly North to South would be a straight line so a straight angle
Answer:
Since both and , you can use a normal distribution to approximate the binomial distribution.
The mean is of 11.1 and the standard deviation is of 2.64.
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
Using the normal distribution to approximate the binomial distribution.
This is possible if:
A survey of U.S. adults found that 37% have been to court. You randomly select 30 U.S.
This means that
Test if it is possible:
Since both and , you can use a normal distribution to approximate the binomial distribution.
Mean and standard deviation:
The mean is of 11.1 and the standard deviation is of 2.64.
1 year has 365.25 days in it (that's why we add a leap day every 4 years)
1day=24hours
1hour=60mins
1min=60secs
365.25*24*60*60=31557600 seconds in a year
2.05*10^5=205000 seconds
205000/31557600=0.0064905800187593479859051385403 years
Answer: B
Explanation: 4 times 3 is equivalent to 12 and the question was asking for exponents. A has 3 multiplied by itself 3 times so that is correct. C has 6 multiplying itself 4 times so that would be correct. D has 5 Multiplying itself 2 times so that would be correct. The only one that does not represent equivalency would be B.
Amount Tyler has: y
Amount Stephanie has: ($50) 38 + y
38+y = 50
y= 50-38
y= 12
Tyler has $12 in his wallet
