Answer: a) N(t) = 950e^0.0475t b) 1020
Step-by-step explanation:
a)
N(t) = 950e^0.0475t.
N/B — Base is e (exponential) because growth is continuous.
b)
N = {36/24} =(approximately) 1020
Acute with angles at 89 or smaller, Right with angles at 90 exact, and obtuse with angles with 91 and above
Answer:
Thus, option “c” 10% is correct.
Step-by-step explanation:
The percentage of students that like dubstep = 30%
The percentage of students that like trance music = 25%
The percentage of student that wants only house music = 20%
The percentage of students that like bot dubstep and trance = 15%
Now we have to find the percentage of students that like trance music but nor dubstep.
The percentage of students that like the trance music but nor dubstep = 100% - 30% – 25 % - 20% - 15%
The percentage of students that like trance music but nor dubstep = 10%
Thus, option “c” 10% is correct.
Answer:

Step-by-step explanation:
-For a known standard deviation, the sample size for a desired margin of error is calculated using the formula:

Where:
is the standard deviation
is the desired margin of error.
We substitute our given values to calculate the sample size:

Hence, the smallest desired sample size is 23
Answer:
27
Step-by-step explanation:
Given the expression

According to law of indices, this can be written as;

Hence the required answer is 27
