1. There is no "h" in f(x) = log(x). The question is nonsense.

2. The log function is defined for arguments greater than zero. You're probably expected to select D, though A and B could also be correct.

3. Same deal. The log function is defined for x > -2, but the domain could be restricted to x > 2. You're expected to select FALSE.

4. Same deal. Choose B, though D is also correct.

5. C is the proper choice. (See discussion of the log function, above.)

Part one: Sequence and Series
ASHA 777 [7]

Answer:

- 57

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a + (n - 1)d

where a is the first term and d the common difference

a_{29} = 13 + (28 × - 2.5) = 13 - 70 = - 57

The box plots below show the average daily temperatures in July and August for a U.S. city: two box plots shown. The top one is
sergey [27]

The <em>correct answer</em> is:


The mean for July is smaller than the median; and

the mean for August is larger than the median.


Explanation:


A distribution with a positive skew would have a longer whisker in the positive direction than in the negative direction. A larger mean than median would also indicate a positive skew.


Alternatively, a distribution with a negative skew would have a longer whisker in the negative direction than in the positive direction. A smaller mean than median would also indicate a negative skew.


The whisker in the negative direction for July is longer than the whisker in the positive direction. This indicates a negative skew.


The whisker in the positive direction for August is longer than the whisker in the negative direction. This indicates a positive skew.
