Answer:9x^4
Step-by-step explanation:
6x^4*3x^3 can be simplified to 18x^7 by separating out cand combining like terms [6*3 = 18] and [x^4*x^3 = x^7]
This results in 18x^7 fr the top term
Do the same for the bottom term: 2x^2*x = 2x^3
We can now write: (18x^7)/(2x^3)
The reduces to 9x^4
Answer:
a)
b)Yes
Step-by-step explanation:
n = 593
x = 28
Confidence level = 95%
So, at 95% = 1.96
Formula of confidence interval of one sample proportion:
=
=
=
Hence a 95 percent confidence interval for the proportion of all new websites that were anonymous is
b) May normality of p be assumed?
Condition for normality : np>10 and np(1-p)>10.
and
27.871 and 26.561063
Hence p is assumed to be normal since the condition is satisfied
2/3 = 0.6666666...... (I dont know how to put a bar above the 6)
