Shaun's savings can be modeled by the regression equation y = 6x^2 + 75x+200. Which of the following is the best prediction for
1 answer:
Answer:
D
Step-by-step explanation:
The equation given gives y in terms of x, where y is Shaun's savings and x is the number of months.
<em>We want to know the amount he will save in 25 months, so we can plug in x = 25 into the equation and get a value of y, that is the amount he will save. So:</em>
D is the correct answer.

What this question implies is to determine the total number of factors of 86400
To start with, we determine the prime factorization of 86400
To do this, we continually divide 86400 by 2; when it can not be further divided, we divide by 3, then 7, then 11...
This implies that:
The number of factors d is the solved by:
Where
By comparison:
So:
<em>Hence, there are 96 total ways</em>
