Answer:
geometric
Step-by-step explanation:
The signs of the terms alternate, so it cannot be an arithmetic sequence.
The ratios of terms are ...
6/-3 = -12/6 = 24/-12 = -2
The terms have a constant ratio of -2, so the sequence is geometric.
The moment generating function (mgf) of y is given by

Since the momoent generating function of x is given by

When p tends to 0, we have

Applying L'Hopital's rule we have:

This shows that y converges to <span>a chi squared random variable with 2r degrees of freedom</span>.
For the answer to the question above, Since Rachel makes 3 bracelets an hour, her linear equation should be y=3h. 3 represents the rate of change and h represents the number of hours as a variable.
Oliver's linear equation is y=2h+5 because 2 is the rate of change and 5 is the b value or the y-intercept in a linear equation y=mx+b. To find when both have the same number of bracelets, we find the point of intersection...
2h+5=3h
5=3h-2h
5=h
Therefore in 5 hours, both will have the same amount of bracelets.
