Step-by-step explanation:
Answer: 6.5
Step-by-step explanation:
The number of apples is x, and the number of oranges is y.
"Mia needs to bring at least 25 pieces of fruit to the school picnic."
means that x+y≥25
"She was told to be sure to bring more than 10 apples."
means that x≥10
thus, the inequalities are:
i) x+y≥25
ii) x≥10
Answer:
6 trials
Step-by-step explanation:
The number of rats that run the maze incorrectly after t trials ;
N(t) = 100e^-0.14t
Initial number of rats = 100
45% of rats to run the maze incorrectly ; 45% * 100 = 45 rats
N(t) = 45
N(t) = 100e^-0.14t
45 = 100e^-0.14t
45/100 = e^-0.14t
0.45 = e^-0.14t
Take the In of both sides :
In(0.45) = In(e^-0.14t)
- 0.798507 = - 0.14t
Divide both sides by -0.14
- 0.798507 / - 0.14 = - 0.14t / - 0.14
5.7036 = t
To the nearest whole number :
Number of trials, t = 6 trials
