Answer:
The blank exponent is 3
Step-by-step explanation:
It is given that n^x=1/64 where n=1/4
1/4^x=1/64
1/4*1/4*1/4=1/64, so x=3 works as a solution. You could use logarithms, but it makes things more difficult, especially in this case.
Answer:
Step-by-step explanation:
The given data table is
x : 4 7 10 12 13
y : 5 7 12 14 18
We need to find the equation of the best fit line.
The general form of a best fit line is
.... (1)
where, m is slope and b is y-intercept.
Using the graphing calculator we get
Substitute m=1.383 and b=-1.526 in equation (1).
Therefore, the equation of best fit line is .
