For a normal distribution <em>only, </em>for a population, not for particular sample.
proportion between 1 standard deviation, independent of μ and σ , is given by:
P(Z<1)-P(Z<-1)
=0.841345-0.158655=0.682689
=0.68 (to two places of decimal)
proportion between 2 standard deviations, independent of μ and σ , is given by:
P(Z<2)-P(Z<-2)
=0.977250-0.022750=0.954500=0.95 (to two places of decimal)

Answer: -5x+-10 using the distributive property
Answer:
=14
Step-by-step explanation:
In a rhombus, opposite angles are equal.
In the one provided in the question, 5x° is opposite the angle 70°
Let us equate the two.
5x=70
x=70/5
=14°
The value of x in the figure is 14°
