Answer:
165 ways
Step-by-step explanation:
Selection deals with combination
There are a total of 11 from which 3 are to be selected
11C3 = 11!/3!(11-3)!
= 11!/(3!x8!)
=(11x10x9x8!)/(3x2x8!)
=11x10x9/6
=11x5x3 = 165 ways
2 1/2 pounds = $18
for 1 pound = How many dollars
1 pound = $18 ÷ 2 1 /2
= 18 ÷ 2.5
= $ 7.2
1 pound = 453.6 grams
so 453.6 grams = $7.2
price of 1 gram = 7.2 / 453.6 = $ 0.0158
Answer:
z = -2.85
Step-by-step explanation:
Since the number of nuts per can is normally distributed:
Mean number of nuts (μ)= 500 nuts
Standard Deviation (σ)= 20 nuts
X = 443 nuts
For any given number of nuts X, the z-score is given by:
The z-score for this can of nuts with 443 nuts is -2.85.
1 liter= 1000 ml
3 liter= 3000 ml
