Answer:
24 Years
Step-by-step explanation:
Rule of 72 is an approximation that you can use to estimate the time it will take for something to double in value at a compound rate of interest
use the following equation
72/(i*100)
we have
72/(.03*100)
72/3=24
Using pythagoras theorem,
a^2 + b^2 =c^2
11^2 + 11^2 = c^2
c^2=242
c=
c= 15.556
c=15.6
Answer:
And if we find the individual probability we got:
And replacing we got:
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:
And we can use the complement rule and we got:
And if we find the individual probability we got:
And replacing we got:
Answer:
x=50°
Step-by-step explanation:
52°+78°+x°=180°(by angle sum property)
130°+x°=180°
x°=180°-130°
x°=50°
