The z-score formula is;

(a)

(b)

(c)
The length of the altitude is 
Explanation:
Let ABC be an equilateral triangle.
It has sides of length 16 cm
Let AD be the altitude of the triangle.
We need to determine the length of an altitude.
Let AC = 16 cm and CD = 8 cm
Let us consider the right angled triangle ADC
Using the Pythagorean theorem, we have,

Substituting the values, we get,




The length of the altitude is 
The graph that does not show Y or X
Answer:
length is 3 and width is 8
(You could also switch it. )
Answer:
104%
Step-by-step explanation:
(275 × p) / 100 = 286
((275 × p) / 100) × 100 = 286 × 100
275p = 28600
275p / 275 = 28600 / 275
p = 104
Percent Increase = 104
