Let x represent first number in pair and y represent second number. We can see that x numbers are increasing by 1 on each next pair. y numbers are square of 0,2,4,6 and 8

Knowing all of that let "n" represent the position of the pair starting from 0!

than we can write that the rule is:
(n,(2n)^2)

approximately 9 out of 10 smokers began smoking before the age of 21. In a group of 400 smokers, about how many of them started
Slav-nsk [51]
Greetings!

You can create an equation to solve for x:
9/10=x/400
Cross Multiply.
9*400=10*x
3600=10x
Divide both sides by 10.
(3600)/10=(10x)/10
The Answer Is:
360=x


Out the 400 smokers, approximately 360 of them started smoking before age 21.

Hope this helps.

kobusy [5.1K]

Answer:721

Step-by-step explanation:It is 721 because when you have a sale tax you add it and that 100%+6%=106%=1.06 then 350x1.06 which equals to 371. Since it’s sales tax then 371+350=721. So it is $721.

If s is true and j is false, is the following true or false (~s v j) ^ (s v~ j)
nexus9112 [7]
S = true
~s = false
-------------
j = false
~j = true
-------------
~s = false and j = false, so,
~s v j = (false) v (false)
~s v j = false
-------------
Similarly,
s v ~j = (true) v (true)
s v ~j = true
-------------
We have 
~s v j = false
and 
s v ~j = true
which lead to this when we conjunct the two logical expressions
(~s v j) ^ (s v ~j) = (false) ^ (true)
(~s v j) ^ (s v ~j) = false
-------------
-------------
The final answer is false
