Answer:
c(n) = 4n +20
let m = c(n)
m= 4n +20
make n the subject
<u>m</u><u> </u><u>-</u><u>2</u><u>0</u><u> </u><u> </u> =n
4.
inverse function of c(n)= <u>n-20</u><u> </u>
4
It is a must that one replaces the m with the n in order to get the final answer
A number has fixed number of factors but infinite number of multiples
Ex:-
Take a number 12
It has factors 1,2,3,4,6,12
It is fixed.
But
It has multiples 12,24,36,48,60...
It is infinite
Answer:
Option C
Step-by-step explanation:
18/36 = 72/144
Multiply each identity on the left hand side by 4
(18×4)/(36×4) = 72/144
which is equal to the right hand side..
They are equivalencies
Answer:
the residual is 0.2032
Step-by-step explanation:
The regression line has been given as:
Y^ = 0.00753X-0.06759
The paired observation for X is (31, 0.369)
The value of X is the empathy score under subject 15 = 31
The value of the brain activity under subject 15 is 0.369
So we have y^ = 0.00753(31) - 0.06759
= 0.1658
Then the residual = y - y^
= 0.369 - 0.1658
= 0.2032
Therefore the residual is 0.2032
