Answer:
- B: The pesticide DDT has a half-life of 15 years.
- C: March Madness has 64 teams in the bracket. Each round, half the teams are eliminated.
- D: After an antibiotic is added to a culture of bacteria, the number of bacteria is reduced by half every three hours.
Step-by-step explanation:
Exponential decay describes a situation in which the dependent variable is reduced by the same factor when the independent variable is increased by the same amount.
A — the population is increasing, not being reduced
B — the amount is cut in half when time increases by 15 years (exp. decay)
C — the number of teams is cut in half when the number of rounds increases by 1 (exp. decay)
D — the amount is cut in half when time increases by 3 hours (exp. decay)
E — the population is increasing, not being reduced
D.
The equation would look like this
62,000(1+.04)^6
Domain: [1 ; 6]
Range: [1 ; 7]
Answer:
50 employees
Step-by-step explanation:
We can set up a proportion which would be
4/x = 8/100
This shows 4 out of x people is the same as 8% of 100.
We divide 100 by 8, and then multiply by 4 to get 50.
We can check this by plugging 50 into the proportion.
4/50 = 0.08
8/100= 0.08
There are 50 total employees at the shop.
Answer:
E) 9/12
Step-by-step explanation:
well first you need to know the number of non-red objects. There are 12 total so 12-3=9 non-red objects
9 out of 12 are non-red which is the exact same as the number of chances you have. 9/12
