Answer: the answer is 45.5, which the second bubble down.
Step-by-step explanation:
The 4 7/8 = 39/8 = 13 pieces of string, he needs 20 so he will need to cut 7 more pieces
Answer:
No. They are slightly pointed. Even if it has the slightest angle that is not 180 degrees, then it is not parallel.
Step-by-step explanation:
Answer:
The recursive formula is aₙ=aₙ₋₁ -12
Step-by-step explanation:
Recursion is a process in which each step of a pattern depends on the step or the previous steps. So a recursive sequence is a sequence where terms are defined using one or more previous terms that are given.
So a recursive formula allows you to find any term in an arithmetic sequence using a function of the previous term, where each term is the sum of the previous term and the common difference.
So, in this case you can see the common difference of all the terms by doing the following calculations between a term and its previous value:
-13-(-1)=-13+1=-12
-25-(-13)=-25+13=-12
-37-(-25)=-37+25=-12
The common difference is -12
So, <u><em>the recursive formula is aₙ=aₙ₋₁ -12 where each term is the same
to the previous term minus 12.</em></u>
Answer:
99.05% probabilitiy that at most six cars are black.
Step-by-step explanation:
For each luxury car, there are only two possible outcomes. Either it is black, or it is not black. The probability of a luxury car being black is independent from other luxury cars. So we use the binomial probability distribution to solve this question.
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.
In this problem we have that:
If 25 cars of that year and type are randomly selected, find the probabilitiy that at most six cars are black.
In which
99.05% probabilitiy that at most six cars are black.
