We solve this by using the z statistic, the formula for z
score is:
z = (x – u) / s
where x is the sample value = 11.25, u is the mean = 12,
and s is the standard deviation = 0.5
z = (11.25 – 12) / 0.5
z = -1.5
From the standard probability tables, the p value is:
P = 0.06680
I think the answer is r < -1/2

Answer:
$6 each
Step-by-step explanation:
the first 10 multiples of 3 are 3,6,9,12,15,18,21,24,27,30
3×2=6
6+6=12
The graph of 4|x| is shaped like a V where the vertex is at the origin ( because when x = 0 y=0) All y values are positive ( because of the absolute value |x| )
Refection in the x-axis will make all the y values change from positive to negative so the answer is y = -4|x|
g(x) = -4|x|
