Answer:
True
Step-by-step explanation:
Confidence interval for banking service in a given confidence level can be calculated as M±ME where
- M is the mean banking service in the sample and
- ME is the Margin of Error
margin of error (ME) is calculated using the formula
ME=
where
- t is the corresponding statistic in the given confidence level
- s is the standard deviation of the sample(or of the population if it is known)
t-statistic for 99% confidence level is always bigger than 95% confidence level which makes Margin of Error bigger and thus confidence interval wider.
Answer:
Its D, 5 4/9
Step-by-step explanation:
So you can turn them into improper feactipons if it’s hard at first (I can already do it without turning them into improper so it’s asker for me)
so 19/9-2/9+32/9
Now add them like you normally would since all the denominators are the same.
you’ll get 49/9
now just simplify that into a mixed mnumber
5 4/9
Answer:
Step-by-step explanation:
put x-√2=0
x=√2
put x=√2 in x^4-6x^2+8
we get (√2)^4-6(√2)²+8
=4-12+8
=0
Remainder=0
and x-√2 is a factor of the given polynomial.
