Multiply the 3 by 16 and the 16 by 3 to even the numbers to 48.
then multiply the 2 above by 16 and the 3 above by 3 so it becomes like this
I hope this helps you
3y-2=y+4
2y=6
y=3
Perimeter=4+6+7
Perimeter=17
You find how y and x change and then divide y/x to get your rate of change
Answer:
A. positive slope.
Step-by-step explanation:
In the least square linear regression of Y on X, the straight line of best fit is given by,
------------------(1)
[where is the estimated value of Y]
Clearly, here,
Slope pf the line = ---------------------------------(2)
Y- intercept = -----------------(3)
and,
X - intercept = ----------------(4) [putting in (1) and taking the value of X]
So,
since
[since or will result in a degenerate distribution, hence these cases are discarded]
so, correlation coefficient = > 0 implies
A. positive slope. [as evident from (1)]
clearly from (3) and (4) all the other options are false.
The sequence is given by the formula
, where n is the value of the n'th term in the sequence.
Thus,
T(1) calculates the value of the 1st term
T(2) calculates the value of the 2nd term
T(3) calculates the value of the 3rd term
.
.
an so on
the value of the third term is T(3)=3*3-1=9-1=8
