Answer:
Hence, the equation is proportional.
Step-by-step explanation:
To test for proportionality ;
y = 12x
For a proportional relationship ;
y α x
y = kx ; where, k is the constant of proportionality.
From. The equation given
y = 12x ; 12 is thw proportionality constant.
Answer:
I think A or D but i'm stuck on D
Step-by-step explanation:
The slope of the line is 3/2
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:
4
Step-by-step explanation:
Given:
A, B, C, D have distinct positive values for mod 6
A (mod 6) = 1
B (mod 6) = 2
C (mod 6) = 4
D (mod 6) = 5
Each mod 6 value cannot be a zero since the product ABCD is not a multiple of 6.
Furthermore, in order that ABCD mod 6 > 0, we cannot have a residue equal to 3, else the product with a residue 2 or 4 will make the product a multiple of 6.
Thus the only positive residues can only be 1,2,4,5
A*B*C*D (mod 6) > 0 = 1*2*4*5 (mod 6) = 4
