The hourly wages earned by 20 employees are shown in the first box-and-whisker plot below. The person earning $15 per hour quits
agasfer [191]

Answer:

<h2>The mean decreases, and the median remains the same.</h2>

Step-by-step explanation:

Remember that a box plot is made by the quartiles of the distribution, the maximum value and the minimum value. So, from a box plot we can deduct the range, the median and the interquartile range.

In this case, the median remains the same at $9.5 per hour. The median is indicated by the middle line of the box, and you can observe that it doesn't change.

Now, the range of the data set decreases from 7 to 3.

On the other hand, the mean must decrease, because data greater than $11 doesn't exist in the box plot number 2, and the mean is a central measure sensible to those changes.

Therefore, the right answer is <em>The mean decreases, and the median remains the same.</em>

PLEASE HEP ME QUICK!!!!: Tom travels between the two mile markers shown and then finds his average speed in miles per hour. Sele
slega [8]

Answer:

speed=\frac{195\ miles}{3\ hours}

3\ hours=\frac{195\ miles}{speed}

3\ hours*(speed)=195\ miles

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the distance in miles

y ----> the time in hours

speed=\frac{x}{y}

we have

The distance is equal to subtract 35 miles from 230 miles

x=230-35=195\ miles

The time is equal to subtract 1:30 pm from 4:30 pm

y=4:30\ pm-1:30\ pm=3\ hours

substitute in the formula of speed

speed=\frac{195\ miles}{3\ hours}

<em>Isolate 3 hours</em>

3\ hours=\frac{195\ miles}{speed}

<em>Isolate 195 miles</em>

195\ miles=3\ hours*(speed)
