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:
sorrryyyy i didn't mean to answer!!!
Step-by-step explanation:
<h3>Inequality</h3>
75d + 30c ≥ 255
<h3>Examples</h3>
(1) If someone bought five DVD players and ten cordless telephones, the equation ((75)(5)+(30)(10)≥255) would be true.
(2) If the electronic store had a parcticularly bad day and they sold two DVD players and one cordless telephone, the equation ((75)(2)+(30)(1)≥255) would be false.
Answer:
a^11
Step-by-step explanation:
a to the power of 2 to the power of 3 equals to a to the power of 6
then, multiplied to a to the fifth, you add 5 by 6, which is 11
Equation:
(4/(x-2))+(1/((x^2)-4))=(1/(x+2)
Answer:
A: She found one valid solution and no extraneous solutions.
Step-by-step explanation:
When solving you get x= -(11/3)
