Answer:
Approximate weight of cell phone is between 100 gm to 200 gm.
1 Pound = 0.45359237 Kilograms
= 0.4545 kg
2.8 pound = 2.8 × 0.4545
= 1.2727 Kg
It is given that weight of cell phone is 
pounds, means 
Kilograms.
Which is equal to, 
grams.
Because, 1 Kilogram = 1,000 gram
If, n=0
Weight of cell phone = 1272.7 grams=1.2727 Kg
when, n=1
Weight of cell phone = 12727 grams=12.727 Kg
n= -2,
Weight of cell phone = 12.727 grams
n=- 3
Weight of cell phone = 1.2727 grams
None, of the weights are appropriate weight of cell phone.Neither of four options provided here is true.
8
= 2^3
= 2* 2* 2
The prime factorization of 8 is 2* 2* 2.

Answer:
45
Step-by-step explanation:
Given that :
Voucher awarded (x) :
Repair = $50
Lose or destroy = $200
P(x):
Replacement voucher = 5%
Repair voucher = 10%
X ______ 50 ______ 200
P(x) ____ 0.1 _______ 0.05
Expected variance Var(X) :
ΣX²p(x) - E(x) ;
E(x) = Σx*p(x) = (50*0.1) + (200*0.05) = 15
ΣX²p(x) = Σ[(50^2 * 0. 1) + (200^2 * 0.05)] = 250 + 2000 = 2250
Var(X) = 2250 - 15^2 = 2025
Standard deviation = √Var(x)
Standard deviation = √2025
Standard deviation = $45
