Answer:
An = 5n-18
Step-by-step explanation:
hello :
note : the n th term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d and A1 the first term
in this exercice : d = 2-(-3)=-3-(-8) =5 A1 = -13
the n th term of an arithmetic sequence is :An =-13+(n-1)(5)
An = 5n -5 -13
An = 5n-18
The relative frequency with which the coin will land on tails 12 of those times willl be 48%. None of the given options are correct.
<h3>What is the formula for calculating the joint relative frequency?</h3>
Assume you need to compute the joint relative frequency of a certain category inside a larger category. Then there's the proportion of that specific category's frequency to the total frequency of that large category.
If the experiment is run 25 times and we receive tails 12 times, the relative frequency of receiving tails is as follows:
Hence, the relative frequency for the given condition will be 48%.

2x+6 is the base
Then the equation is logarithm of 144 on basis 2x + 6 = 2
Then [2x + 6]^2 = 144
Now expand the square binomial
4x^2 + 24x + 36 = 144
4x^2 + 24x + 36 - 144 = 0
4x^2 + 24x - 108 = 0
Divide by 4
x^2 + 6x - 27 = 0
Factor: (x + 9 ) (x - 3) = 0
x = -9 and x = 3
The only valid is x = 3, because x = -9 yields 2x + 6 = - 12 and the logarithm function cannot have negative basis.
Then the answer is x = 3.
