Answer:
The population reaches 42,336 fish in 2258
Step-by-step explanation:
<u>Given</u><u>:</u>
<u>To Find:</u>
Time taken to reach 42,336 = ?
<u>Solution:</u>
According to the question x is the number of years after which the population .
Then
= 0
Solving using quadratic formula
x=261.337 x=−261.268
Neglecting the negative value we get
x = 261.337
x = 261 approx
261 years after 1997 = 2258
First u add ten to both sides to cancel out. Now you have 14=-7s. Since you are trying to do the opposite operation, you divide by -7 on each Sides. Now you have -2=s. Hope this helped
To find the mean, add all the numbers, then divide by the amount of numbers there are. I'll do the first one as example.
6+5+6+9+9+11=46.
46 divided by 6 = 7.66
To find the median, put all the numbers in order from biggest to smallest.
5, 6, 6, 9, 9, 11.
Since there is an even amount of numbers, you have to add the two middle numbers (6,9) and divide by two.
6+9= 15
15 divided by 2 = 7.5
To find the mode, you just have to find the most common number. In this case, there are two most common numbers (6,9) so the answer would be both.
5,6,6,9,9,11
Answer:
Mean: 7.66
Median: 7.5
Mode: 6,9
Answer:
- 66
Step-by-step explanation:
Evaluate g(- 4) then substitute the value obtained into f(x) , that is
g(- 4) = - 2(- 4)² = - 2 × 16 = - 32, then
f(- 32) = 2(- 32 - 1) = 2 × - 33 = - 66
