Using y = mx + b
m = 3 and b = 4
so
equation
y = 3x + b
Acute is a smaller angle
Obtuse is a big angle then rught and acute
Right: an angle thats 90° :)
Answer:
The correct answer is C.
Step-by-step explanation:
percentile is represented as the value of probability in the norma distribution.
We look for a z-value with a left-tail of 0.67.
z=0.44
where,

M: mean
SD: standar deviation
x=z×SD+M=0.44×0.3+M=M+0.132
The diameter of an orange at the 67^th percentile is 0.132 inch above the mean.
