Answer: A
Step-by-step explanation: 256 times 2.5% is 256 times 0.025 which equals 6.4. Add 6.4 to 256
4^3*4^-5= 4^-2 (add the exponents since the base is the same)
5^-4*5^1= 5^-3 (add the exponents since the base is the same)
Square both terms (double the exponents)
(4^-2)^2= 4^-4
(5^-3)2= 5^-6
Then take out negative exponents (x^-a= 1/x^a)
4^-4 /5^-6 = 5^6/4^4
Final answer: 5^6/4^4
If you want it in number form
5^6= 15625
4^4=256
15625/256= 61.035...
Answer:
There is a 3/95 probability that a granola bar is chosen one choice after the other without replacement.
Step-by-step explanation:
The probability of choosing a granola bar without replacing the first bar is 4/20, or 1/5. 4 represents the number of granola bars, and 20 represents the total snacks. Then there are 19 snacks and 3 granola bars which represents the 3/19 chance of getting a granola bar the second time without replacing it.
To find the probability of both of those events happening, multiply them.
(1/5) * (3/19) = 3/95.
