We get tne n-th term with: tn=1/3tn-1
We know that the first term is t1=81, so 81=1/3t*1-1
81=1/3t-1
82=1/3t
82*3t=1
3t=1/82
t=1/82*3=1/246
The second term is: 1/
2*(1/246)*2)-1
We get the third term by replacing n with 3 and so on...
Answer:
$268.80
Step-by-step explanation:
You multiply 336 by 0.2 as it give what the 20% is, which is 67.2. You then subtract 336 by 67.2 and get the value from last year.

Answer is 10(2k+5)
-----------------------------------
Work Shown:
20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)
Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer
Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
Answer:
0.20148
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 230
μ is the population mean = 184
σ is the population standard deviation = 55
z = 230 - 184/55
z = 0.83636
P-value from Z-Table:
P(x<230) = 0.79852
P(x>230) = 1 - P(x<230) = 0.20148
Therefore, the probability that the eye contact time is greater than 230 seconds is 0.20148
