Answer:
it's answer is B
Step-by-step explanation:
f (x)=x (x-2)+3 (x-2)
=x2+x-6
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
This can be represented by the expression 4d.
Answer: m=-4.75
Step-by-step explanation:
-18v^2 + 23v^2 =
In order to find the solution to this problem we are gonna add like terms.
-18v^2 + 23v^2
= 5v^2
A negative plus a positive results to a positive
