Answer:
A
Step-by-step explanation:
Eccentricity = 6/5
Hyperbola
Directrix: x = 3/2
Answer:
471.24
Step-by-step explanation:
Looking at the given points on the right side from (0,2) to (1,6) for 1 increase in X ( 1-0=1) the Y value increases by 3 ( 6/2 = 3)
This same increase happens for th other two points: 18/6 = 3
54 / 18 = 3
The rate of increase is 3.
• Donny's bagels is the better deal.
1. It have Lower ratio.
2. Bob's bagels are 10 for $11
Unit price for Bob's bagels = $11 / 10 bagels = $1.10 per bagel
Donny's bagels are 4 for $3
Unit price for Donny's bagels = $3 / 4 bagels = $0.75 per bagel
3. Donny has the better deal, because Donny's unit price is less than that of Bob's ( each of Donny's bagels cost less than each of Bob's bagels).
Answer:
The method of moment (MOM) estimator as:
Step-by-step explanation:
From the question, the correct format for the probability density function is:
where θ > 0 is an unknown parameter.
(a) The MOM estimator can be calculated as follows:
suppose E(X) =
Then;
making the subject of the formula, we have:
squaring both sides, we have:
The method of moment (MOM) estimator as:
b) If the observations are
Then,
Finally, the point estimate of the estimator is
