Answer:
0.02
Step-by-step explanation:
Given a normal distribution :
Mean income (m) = 25000
Standard deviation of income (s) = 6000
X ≥ 12000
Using the relation to fund the standardized score :
Zscore =(x - m) / s
Zscore = ( 12000 - 25000) / 6000
Zscore = -13000 / 6000
Zscore = - 2.167
Using a z probability calculator :
P(Z ≤ - 2.167) = 0.015117
= 0.02
When you solve an equation, it has an equal sign (=) and inequalities do not. When you solve an inequality the answer isn't exact (depending on the sign ie: <, >, etc...) equations usually are exact answers. other than that, I don't think there is a big difference in solving them.
Answer:
Step-by-step explanation:
(1) A typical form of equation of a line is:
with, 
is slope and 
is y-intercept.
(2) Another straight line has equation in form of:
with 
is slope and 
is y-intercept
(3) If these two lines are perpendicular, according to the property of two perpendicular lines on the two-dimensional plane, we have:
x = -1
(4) Transform the given equation of original line into typical form:
<=> 
<=> 
<=> 
=> 
=> 
=> Option D: 
is correct (Slope = 
)

Each hour has 60 minutes, so we need to compute 5/12 of 60 min which is
let's recall that there are 16oz in 1 lbs, so then 12lbs is 12*16 = 192oz, plus 5, that makes it 197oz, so then 12lb 5oz is really 197oz.
likewise, 7lb is 7*16 = 112oz, plus 10 that makes it 122oz.
197 - 122 = 75 oz
and 75 oz is just 16+16+16+16+11, 4lbs and 11 oz.
