<span>Solve for "x":
a/x = x/4a
---
x^2 = 4a^2
x = 2a</span>
Depends is the positive integer is larger than the negative interger for example -10+5=-5.
10+-4=6
x = number of hours
want to find probability (P) x >= 13
x is N(14,1) transform to N(0,1) using z = (x - mean) / standard deviation so can look up probability using standard normal probability table.
P(x >= 13) = P( z > (13 - 14)/1) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413
To convert that to percentage, multiply 100, to get 84.13%
Answer:
19
Step-by-step explanation:
51-(16)x2
16x2=32
51-32=19
Solution: We are given:
μ=180,σ=25,n=100
Therefore the standard error of the mean is
