29. Family income in the middle class: Bauer et al. (2011) identified the median income of a middle-class family in their sample

GREYUIT [131]

Answer:

No it is not

Step-by-step explanation:

The median is 84200

The mean is 85300

Low income is 65100

High income is 103400

From this information, we can see a skewed data. The mean would not be a good estimate value. Rather the center (median) would be more appropriate.

When we calculate the middle value for this data

65100+103400 = 168500/2 = 84250

84250 is closer to the median score of 84200. The median is best in the presence of outliers.

In t hours the train has traveled s miles. Find the formula for v, the speed of the train (in mph) in terms of t and s. Find the

Digiron [165]

Answer:

Part 1 .

As per the given statement: In t hours the train has traveled s miles.

Distance of the train = s mile

Time = t hours

Formula for :

Speed of the train(v) = $\frac{\text{Distance of the train}}{\text{Time}}$

$v = \frac{s}{t}$ mph .....[1]

Substitute the value of t = 3 hours and s = 180 miles in [1], to solve for v;

$v = \frac{180}{3} = 60 mph$

Therefore, the speed of the train(v) is, 60 mph

Part 2.

Similarly,

The formula for speed of the train (v) is given by;

$v =\frac{s}{t}$

Substitute the value of t = 2.5 hours and s = 225 miles to solve for v;

$v = \frac{225}{2.5} = 90 mph$

Therefore, the speed of the train(v) is, 90 mph
