I´m pretty sure that the terms would just be 3, 4, and 5. It depends what kind of problem it is.
Answer:
The following would be best modeled by an exponential decay function
A.) An island is being eroded away and loses 10% of its beachfront every year.
D.) A machine depreciates (loses value) by $1000 in its first year, by $2000 in its second, $3000 in its third, etc.

Answer:
C.I. at 95% is as C.I.[0.7504 to 0.8162]
Step-by-step explanation:
Given:
Total number n=600
and Required No of students=x=470
To Find:
Determine a 95% confidence interval .
Solution:
Using normal distribution table for Z,
when 95 % C.I. Z=1.96
Now calculate ,
Population proportion,p=x/n
p=470/600
p=0.7833
Now calculate margin of error
MOE=Z*Sqrt[p(1-p)/n]
MOE=1.96*Sqrt[(0.7833*0.21667)/600]
=1.96*Sqrt(0.00028286)
=1.96*0.01681
=0.0329
So
The Boundaries will be as follows:
1)p-MOE
=0.7833-0.0329
=0.7504
2)p+MOE
=0.7833+0.0329
=0.8162
Answer:
Step-by-step explanation:
Total no. of children = 366
let the number of boys be x
and the no. of girls be x + 28
According to the question,
x + x + 28 = 366
2x + 28 = 366
2x = 366 - 28
2x = 338
x = 338 / 2
x = 169
So the no. of boys = x = 169
and the no. of girls = x + 28 = 169 + 28 = 197
( you can also recheck it by adding the no. of boys and the no. of girls
that is, 169 + 197 = 366 which equal to the total no. of children )
