Answer:
0.025 is the standard error of mean.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 100
Sample mean = 13 psi
Population standard deviation = 0.25 psi
We have to find the standard error of the mean.
Formula:
Standard error =
0.025 is the standard error of mean.

Answer:
645320
Step-by-step explanation:
Given: 6_5_2_
If a multiplication sign is placed between the second and third digit, and an equal sign is placed between the third and fourth digit, then
6_ × 5 = _2_
The passcode contains 6 DIFFERENT digits, so we know the missing numbers cannot be 6, 5, or 2.
So, do a trial and error session of multiplying 5 by numbers it could possibly be (60, 61, 63, 64, 67, 68, 69).
64 × 5 = 320. It is the only equation that is both correct and matches the digits given, so the missing digits are 4, 3, and 0. Barry's passcode is 645320.
