y=15
5y-20=2y+25 move terms
5y-2y = 25+20 calculate like terms
3y=45 divide both sides by 3
Answer:
102
Step-by-step explanation:
Since 2 + 8 = 10, then the cube root of 5x+2 = 8
Since 8×8×8=512, then 5x+2=512
5x=510, so x=102
Answer:
In 2050 fish population is 27000
Step-by-step explanation:
Exponential change can be modeled by,
Where 
is the initial value of 750, 
is the rate of change. It is greater then 1 when there is growth and less then 1 when there is decay. and 
is the number of time periods.
The rate of change in percentage is 8.3%
That means, after 1 year fish will become 108.3 for 100 fish.
Then 
Difference of years is, 
Then, 
So, the fish population in 2050 is 27000

Answer: i think method of least squares (d.)
Step-by-step explanation: i’m pretty sure this is correct because mean is good for unimodal, unskewed histograms, median is good for unimodal asymmetrical histograms, and mode is good for bimodal histograms. i’m not sure tho bcs i learned this in statistics.
