Answer:
x² + 4x - 12, remainder - 60
Step-by-step explanation:
Using synthetic division to divide
Since dividing by x - 1, evaluate for x = 1
1 | 1 3 - 16 - 48
↓ 1 4 - 12
---------------------------
1 4 - 12 - 60 ← degree 2 polynomial
quotient = x² + 4x - 12, remainder = - 60
Hence
= x² + 4x - 12 - 
Since the function and choices are already given, the simplest method would be to try out the given values of x and see if the value of y obtained and given int he choices would coincide. Using this trial and error method, it has been shown that the correct answer among the choices is choice C, with the solution shown below:
y = -0.296x^2 + 2.7x
Using (4.6, 6.2):
y = -0.296(4.6)^2 + 2.7(4.6)
y = 6.2
In one sample t-test, you compare it to some value that you already know to represent the population mean. In the t-test for correlated groups, the statistic is the difference between your two samples, which you test against the population mean difference.
