2300*.065 = 149.5
149.5*10 = 1495
2300 + 1495 = $3795
Answer:
The online survey has large biases concerning representativeness. Regarding the behavioural characteristics of consumers, the face-to-face data delivers the best results, followed by the telephone interviews and finally the online survey.
Face-to-face surveys still deliver the most representative results. Telephone surveys may provide a good alternative, but we would advise use of a larger sample. The online survey needs to be corrected, one should relinquish representativeness.
Answer:
1/10,737,573
Step-by-step explanation:
The number of possible outcome is
47 combination 6
nCr=n!/(n-r)!r!
Then,
47C6 = 47!/(47-6)!6!
47C6=47!/41!6!
47C6=47×46×45×44×43×42×41!/41!6×5×4×3×2×1
47C6=47×46×45×44×43×42×/720
47C6=10737573
This the sample space of groups 6 numbers.
So to win a jackpot, you need to pick one of the possible outcome
P(winning jackpot)= 1/10,737,573
Wow, this result shows that it is not easy to win a jackpot from lottery games, it is on rare occasions to have the combine 6 numbers.
Answer:
1.39
Step-by-step explanation:
Creating a table:
X :___0 __ 1 __ 2 ___ 3 ____ 4 ___ 5 ___ 6
P(x):0.02_0.03_0.07, 0.12, 0.30_ 0.28_0.18.
The standard deviation = sqrt(Var(x))
Var(x) = Σx²*p(x) - E(x)²
E(x) = ΣX*p(x)
E(x) = (0*0.02) + (1*0.03) + (2*0.07) + (3*0.12) + (4*0.30) + (5*0.28) + (6*0.18) = 4.21
Var(X) :
((0^2*0.02) + (1^2*0.03) + (2^2*0.07) + (3^2*0.12) + (4^2*0.30) + (5^2*0.28) + (6^2*0.18)) - 4.21^2
19.67 - 17.7241
= 1.9459
Standard deviation = sqrt(Var(X))
Standard deviation = sqrt(1.9459)
Standard deviation = 1.3949551
= 1.39
Answer:
56 is the other number
Step-by-step explanation:
let the first number be a
the other number is 5/14 from the question
a x 5/14 = 20
5a/14 = 20
5a = 14 x 20 = 280
a = 280/5 = 56
