Answer:
0,4,24,60,112
Step-by-step explanation:
an = 8n² − 4n
first 5 terms is a0, a1, a2, a3 and a4
for a0, n = 0,
a0 = 8(0)² − 4(0) = 0
for a1, n = 1,
a1 = 8(1)² − 4(1) = 8-4 = 4
for a2, n = 2,
a2 = 8(2)² − 4(2) = 8(4)- 4(2) = 32-8 = 24
for a3, n = 3,
a3 = 8(3)² − 4(3) = 8(9) − 4(3) = 72 - 12 = 60
for a4, n = 4,
a4 = 8(4)² − 4(4) = 8(16) − 4(4) = 128 - 16 = 112
hence the first 5 terms are
0,4,24,60,112

Answer:
The margin of error for the 90% confidence interval is of 0.038.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is of:
To this end we have obtained a random sample of 400 fruit flies. We find that 280 of the flies in the sample possess the gene.
This means that 
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Margin of error:
The margin of error for the 90% confidence interval is of 0.038.
Well, we can use some simple addition, okay? So if Ally has 7 cubes, and Greg has four, we can use the equation: x+y = ?, so 7 + 4 = 11. x and y don't mean anything in this scenario, but I just used them as variables. I hope this helps! :)
