Answer:
B
Step-by-step explanation:
Given:
Initial mass, m₀ = 23 g
Decay constant, k = 0.13
Exponential decay obeys the equation
where t = time, days
For half life, the mass is m = m₀/2.
Therefore
Answer: The half life is 5.33 days
Answer:
H₀: μs = μf
H₁: μs ≠ μf
Step-by-step explanation:
Hello!
If the company wants to compare the sales of both departments "snacks" and "frozen foods" to see if there is any difference, the best is to compare the average number of sales of them.
Then the parameters of interest will be:
μs= average number of sales of the "snacks" department.
μf= average number of sales of the "frozen food" department.
The objective is to test if there is any difference between both departments, then the hypothesis should be two-tailed:
H₀: μs = μf
H₁: μs ≠ μf
I hope it helps!
Answer: -7=0 --> Impossible
Step-by-step explanation:
2x-7+x-11= 3x-11
2x+x-7-11=3x-11
3x-18=3x-11
3x-18+11=3x
3x-7-3x=0
-7=0
Impossible
Answer: -70
Step-by-step explanation:
1. You subtract 5-7 because of PEMDAS and you get -2
2. multiply 5x7=35
3. Multiply 35x-2=-70
