Answer: 6.73 ft
Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621

Note find probabilities from z-tables
:
Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102
Answer:
y ≤ -4x + 4
Step-by-step explanation:
slope-intercept form is y = mx + b
the inequality you're given is 4x + y ≤ 4
minus 4x from both sides
you get y ≤ -4x + 4
2(3x + 11) = 34
3x + 11 = 34/2
3x + 11 = 17
3x = 17 - 11
3x = 6
x = 6/3
x = 2
