r =
multiply both sides of the equation by r - 3
t(r - 3 ) = r ( distribute and collect terms in r together )
tr - 3t = r
tr - r = 3t ( factor out r )
r(t - 1 ) = 3t ( divide both sides by r - 1 )
r =
Answer:
4 minutes because when the line hits Y=8 X=4
Also the answer to a) is 8,000
Answer:
The solution is x=4.
BRAINLIEST :)
It is not an extraneous solution.
Answer:
99.8% probability of at least one failure.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Probability of success is 30%.
This means that
Five trials:
This means that
Find the probability of at least one failure in five trials of a binomial experiment in which the probability of success is 30%.
Less than five sucesses, which is:
In which
0.998*100% = 99.8%
99.8% probability of at least one failure.

7000 has 7 in place 1
1700 has 7 in place 2
1170 has 7 in place 3
1117 has 7 in place 4
