The solution is the interval (-∞,6)

Step-by-step explanation:

we have

-----> inequality A

solve for x

The solution of the inequality A is the interval (-∞,-10)

----> inequality B

solve for x

The solution of the inequality B is the interval (-∞,6)

so

The solution of the inequality A or inequality B is

(-∞,-10) U (-∞,6)=(-∞,6)

The solution is the interval (-∞,6)

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
