Answer:
A function that gives the of tickets is given by
where u is number of consecutive wins
Step-by-step explanation:
Given that,
Initial amount of fans is =200.
For each wins, the number ticket sells is also increased by a factor of 1.1.
After 
win, the number of tickets fans will be 200×1.1
After 
win, the number of tickets fans will be 200×1.1×1.1
=200(1.1)²
After 
win, the number of tickets fans will be 200×1.1×1.1×1.1
=200(1.1)³
and so on.
After 
win, the number of tickets fans will be 
.
A function that gives the of tickets is given by
where u is number of consecutive wins
<u>Answer:</u> The value of x will be 2.
<u>Step-by-step explanation:</u>
To calculate the value of 'x' or solve for x, we need to isolate x from 8.
In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.
Reverse operation of addition is subtraction.
We need to subtract 8 from both sides of the equation, we get:
By doing this, we get the value of 'x' as 2.
Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.
The mean is just the arithmetic average:
(103+99+90+86+105+96+x)/7=95
(579+x)/7=95
579+x=665
x=86

If (2, -1, 2, 1) is a linear combination of the three given vectors, then there should exist 
such that
or equivalently, there should exist a solution to the system
Right away we get 
, so the system reduces to
Notice that the first equation is the sum of the latter two. The third equation gives us
so that in the second equation,
which in turn gives
and hence the (2, -1, 2, 1) is a linear combination of the given vectors, with
