Answer:
Step-by-step explanation:
Given that a grocery supplier believes that the mean number of broken eggs per dozen is 0.8 with a standard deviation of 0.6.
Here we assume the cartons of eggs are independent
a) Mean value of eggs in 8 dozens = 8 Expected value in 1 dozen
b) Var (8x) (Here 8 dozens)
(assuming independent)
Otherwise we have Var(x1+x2+x3+...)=sum of var of xis + cov (xi,xj)
Thus we have to assume independent to avoid covariance
So Var(8x)=64 Var(x)
STd dev for 8 dozens = 8(0,6) = 4.8
c) To avoid covariance i.e. variance among pairs of dozens we assume independence.
Answer:
x^2 - 3
Step-by-step explanation:
they both contain the variable of x^2 and -3 when factored out it would be
3 and x + 2
Answer:
Option d.
Step-by-step explanation:
we know that
The graph of a continuous probability distribution is a curve. Probability is represented by area under the curve.
The curve is called the probability density function (abbreviated as pdf).
We use the symbol f(x) to represent the curve
therefore
The probability density function f(x) represents . the height of the function at x.
Answer:
39
Step-by-step explanation:
if you drop the radius to less than that, then the Area will also drop to less than 1 unit, in this case it happens to be a decimeter
