Answer:
there are varous answer to this problem but the equation is 30+n
just plug in any number for n and add 30.
Ex:
n=30
30+30=60
Ex:
n = 40
30+40=70

Answer:
y ≥ 1/4x + 2
Step-by-step explanation:
The line is solid, and the shading is above it, so the inequality will have a form similar to ...
y ≥ [the boundary line]
The y-intercept is y = 2, and the slope is 1 unit up for 4 units right, so 1/4. In slope-intercept form, the equation of the boundary line is ...
y = mx + b . . . . . . for slope m and y-intercept b
This boundary line has equation ...
y = 1/4x + 2
So, the inequality is ...
y ≥ 1/4x + 2
Answer:
0.0786
Step-by-step explanation:
Given :
Mean, u = 15
Standard deviation = 0.5
Sample size = 50
Critical region, x' < 14.9
Acceptance region will be, x' ≥ 14.9
H0 : u = 15
H1 : u < 15
P(type I error)
= P(x' < 14.9 when u = 15)
P(z < -1.414)
From the standard distribution table
NORMSDIST(-1.414) = 0.0786
