2x10-1 as the decimal place is 0.2
The exponential function is used. Use x as your variable common ratio.
This is pretty obviously
If it wasn't obvious we can find the common ratio r by dividing successive values:
5/1=5
25/5=5
125/25=5
625/125=5
<h3>What is the common ratio?</h3>
The common ratio is the number you multiply or divide by at each stage of the sequence. You can find it by dividing two consecutive pairs of terms.
That's the common ratio. We multiply by the first term, but the first term is one, so that has no effect.

X is an odd number
x+2 is also odd (consider the example x = 3 so x+2 = 3+2 = 5). Adding 2 to any odd number is always odd
Similarly, so is x+6 (since we have x+2+2+2).
And so is x+10 (x+2+2+2+2+2).
So every value in this list is an odd number. The middle most values are x+2 and x+6 which are both odd.
Adding any two odd numbers together yields an even number. For example 3+5 = 8. Divide this even number in half and we may or may not get an odd number (eg: 8/2 = 4 and 6/2 = 3)
So this statement is sometimes true
Answer: There is probability that he will be asked a question in class during Week 7 is 64%.
Step-by-step explanation:
Since we have given that
Probability that question in class being asked during Week 1 = 1%
Probability that question in class being asked during Week 2 = 2%
Probability that question in class being asked during Week 3 = 4%
and so on.
So, we need to find the probability that question being asked in class during week 7.
Since it forms geometric series:
1%, 2%, 4%, ........
So, we need to find the 7 th term:
Hence, there is probability that he will be asked a question in class during Week 7 is 64%.
Answer:
y = 12
Step-by-step explanation:
set up equation for 'y varies inversely with x': y = k/x
where 'k' is the constant of variation
8 = k/6
therefore, k = 48
value of y when x = 4: y = 48/4; therefore, y = 12
