Answer:
1/3
Step-by-step explanation:
.0026 in scientific notation is 2.6 x 10^-3 so just add 2.6 x 10^-3 + 3.9 x 10 ^-3
Answer:
- f(x) = 5x + 10 and g(x) = 0.2x -2
- f(x) = 1/4x -1 and g(x) = 4x + 4
Step-by-step explanation:
f and g will be inverses if f(g(x)) = x.
A — f(g(x)) = 5(0.2x -2) +10 = x -10 +10 = x . . . . . inverses
B — f(g(x)) = (±√x+3)^2 +3 = x ±6√x +9 +3 ≠ x . . . . . not inverses
(even if it is g(x) = ±√(x+3), the functions are still not inverses)
C — 1/2(2x -7) +7 = x -7/2 +7 = x +7/2 ≠ x . . . . . not inverses
D — 1/4(4x +4) -1 = x +1 -1 = x . . . . . inverses
Answer:
This verified guy is wrong, and all I can say is I resubmitted twice and it's not "He should use the median because it's the center of data" or "He should use the mean because there are no outliers that affect the mean."
Step-by-step explanation:
Actually, it's MEDIAN because there ARE outliers that affect the MEAN. If you take the mean, average, then the $2.5 M house will raise the mean.
