Answer: $\bold{(B)\ a_n=a_{n-1}+4.3\ \text{where}\ a_1=-22.7}$

Step-by-step explanation:

$\text{Given the sequence -22.7, -18.4, -14.1, -9.8, -5.5, the difference (d) is +4.3}\\\text{The general form of the recursive rule for an arithmetic sequence is:}\\a_n=a_{n-1}+d\\\text{With the information provided, the recursive rule is:}\ a_n=a_{n-1}+4.3.\\\text{The first term of the sequence}\ (a_1)\ \text{is 22.7}$

In 2009, the American Time Use Survey found that the average American spends 2.8 hours a day watching TV. Suppose the standard d

Anit [1.1K]

Answer:

4.72 hours/day

Step-by-step explanation:

Mean time spent watching TV (μ) = 2.8 hours a day

Standard deviation (σ) = 1.5 hours a day

The 90th percentile (upper 10%) of a normal distribution has an equivalent z-score of roughly z = 1.282. The minimum time spent watching TV, X, at the 90th percentile is:

$z=\frac{X-\mu}{\sigma} \\1.282=\frac{X-2.8}{1.5}\\ X=4.72\ hours/day$
