Answer:
65.426
Step-by-step explanation:
Given that:
Mean height (m) = 68 inches
Standard deviation (s) = 2 inches
Height required to be taller than 90% of the class :
P(Z > x) = 0.9
The corresponding Zscore is - 1.282 (Z probability calculator)
Using the Zscore relation :
Zscore = (x - m) / s
-1.282 = (x - 68) / 2
-1.282 * 2 = x - 68
-2.564 = x - 68
-2.564 + 68 = x
x = 65.436
Answer:
2/3 , -1/4
Step-by-step explanation:
(3x - 2)(4x + 1) = 0
Either 3x - 2 = 0 or 4x + 1 = 0
or, x = 2/3 or x = -1/4
