The value of a₄ is -9
What is recursively defined sequence?Recursively defined sequence is the sequence where every term is calculated by the use of the one or more previous term given.
In this given problem
a₁ = 5
given relation between term is [tex]a_{n+1}[/tex] = 2aₙ -7
using this relation
take n=1
a₂ = 2a₁-7 =(2*5)-7=3
then by taking n=2
a₃ = 2a₂-7 =(2*3)-7=-1
then taking n=3
a₄= 2a₃-7 =(2*(-1))-7= -9
so the final answer will be a₄ = -9

Answer:
The proof that √2 is indeed irrational is usually found in college level math texts, but it isn't that difficult to follow. It does not rely on computers at all, but instead is a "proof by contradiction": if √2 WERE a rational number, we'd get a contradiction.

The manager of a football team says the probability that the team will win the next match is 0.6 and the probability it will lose is is 0.1 Find the probability that the team will: a) not win b) not lose c) not draw
Answer:
A. 0.4
B.0.9
C.0.7
Step-by-step explanation:
Answers:
a) 0.4b) 0.9c) 0.7===========================================
Explanation:
Part (a)
P(winning) = 0.6 is given
The probability of not winning is 1 - P(winning) = 1 - 0.6 = 0.4
----------------
Part (b)
P(losing) = 0.1 is given
The probability of not losing is 1 - P(losing) = 1 - 0.1 = 0.9
-----------------
Part (c)
The probability of winning is 0.6 and the probability of losing is 0.1
This adds to 0.6+0.1 = 0.7, which must mean 0.3 is the probability of drawing (since 0.7+0.3 = 1)
So the probability of not drawing is 1 - P(draw) = 1 - 0.3 = 0.7, which is exactly the sum of the probabilities of winning and losing.

Answer:
a. 70 gallons of water were leaked each month.
Step-by-step explanation:
Set up an equation:
Variable x = gallons leaked each month
210/3 = x/1
Cross multiply:
210 × 1 = 3 × x
210 = 3x
Divide by 3 to isolate the variable:
70 = x
The division part is only 210 ÷ 3 = x. I wrote it down this way so you can see how I came to this equation.
Check your work:
210/3 = 70/1
210 × 1 = 3 × 70
210 = 210
Correct!

What is PEDMAS rule?PEDMAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on division & multiplication and at last addition and subtraction.
According to the question
Monique goes out for coffee once per week.
She has already spent $40.86 this year on her coffees and each one is $4.54.
There are 27 weeks left in this school year for Monique.
If she continues getting coffee at this rate, money will she have spent on coffee by the end of the year:
Based on the given conditions
[tex]40.86 + 27 \times 4.54[/tex]
By using PEDMAS rule, first we have to multiply 27 and 4.54
= [tex]40.86 + 122.58[/tex]
By using PEDMAS rule, first we have to add 40.86 and 122.58
= [tex]163.44[/tex]
Thus, $163.44 money will she have spent on coffee by the end of the year.
