Answer:

288 miles

Explanation:

Time taken with traffic = 9 hours

Time taken without traffic = 4 hours

Speed with traffic = x mph

Speed without traffic = x+40 mph

Distance = Speed × time

Distance travelled in 9 hours

9x

Distance travelled in 4 hours

4(x+40)

Since both the distances are same

9x-4(x+40)=0\\\Rightarrow 9x-4x-160=0\\\Rightarrow 5x-160=0\\\Rightarrow x=\frac{160}{5}\\\Rightarrow x=32\ mph

Speed with traffic = 32 mph

Distance travelled = 9×32 = 288 miles

∴ Shen lives 288 miles from the mountains

If the sample size is , what conditions must be satisfied to compute the confidence interval?
Gnesinka [82]

In the confidence interval method the sample data must come from a population that is normally distributed with no outliers.

A confidence interval is a range of values derived from observable data at a desired level of confidence that may include the parameter's true value. The confidence level, such as a 95% confidence level, refers to the accuracy of the estimating process rather than the degree of assurance that the computed confidence interval accurately represents the true value of the parameter under investigation. Confidence intervals are typically written as (some value) ± (a range). The range can be expressed as a percentage or as a real amount. The equation used to determine the confidence interval varies depending on which standard deviation is known.

lapo4ka [179]

Answer:

Extended, with at most two conclusions.

Explanation:

In short, an extended argument represents an argument that consists of two or more different sub-arguments. This indicates that you will find conclusions that represent premises for the most important conclusion of the argument. In this case, the main argument is that brokers who specialize in stocks will have a more difficult case to make in weeks to come, and the second argument is that certificates of deposit are an increasingly popular form of investment.
