Answer:
Let X1,X2,...,Xn be i.i.d. random variables with expected value EXi=μ<∞ and variance 0<Var(Xi)=σ2<∞. Then, the random variable
Zn=X¯¯¯¯−μσ/n−−√=X1+X2+...+Xn−nμn−−√σ
converges in distribution to the standard normal random variable as n goes to infinity, that is
limn→∞P(Zn≤x)=Φ(x), for all x∈R,
where Φ(x) is the standard normal CDF.
Step-by-step explanation:
Yes bc both 3/6 and 2/4 equal 1/2
3/4 x 7 = 5.25 lbs
The total weight of the 7 pillows is 5.25 lbs.
Answer:
m<Y = 68°
Step-by-step explanation:
A tangent drawn to a circle makes a 90° angle with the radius that intersects it at the point of tangency. That means that m<X = 90°.
The sum of the measures of the angles of a triangle is 180°.
m<X + m<Y + m<Z = 180
90 + m<Y + 22 = 180
m<Y + 112 = 180
m<Y = 180 - 112
m<Y = 68
Answer:
6.1-10.3
Step-by-step explanation:
Multiply standard deviation times 3 = 2.1
Subtract and add to mean.
