Answer: 2, 9, 14, 17, 19

Step-by-step explanation:

A box plot uses the values: minimum, maximum, median, first quartile and third quartile.

First sort the data from lowest to highest.

2,8,9,11,14,15,17,19,20

Thus, the minimum, or Data Point 1 is 2.

Then find the median.

8,9,11,14,15,17,19

9,11,14,15,17

11,14,15

Thus, the median, or Data Point 3 is 14.

For the 1st and 3rd quartile, simply, ignoring the median, find the median of the first and second half of the data.

8,9,11

Thus, the first quartile, or Data Point 2 is 9.

15,17,19

17.

Thus, the third quartile, or Data Point 4 is 17.

The maximum of the data, or Data Point 5 is 19.

After driving 152 km, 4/5 of a trip is completed. How long is the total trip? How many more kilometers must be driven to compl

nikitadnepr [17]

Answer:

1. Total Trip Distance = 190 kilometers

2. To complete the trip, 38 more kilometers left

Step-by-step explanation:

Let total trip be x kilometers.

So we can say

"152 is $\frac{4}{5}$ of total" --- this into equation is:

$152=\frac{4}{5}x\\x=\frac{152}{\frac{4}{5}}\\x=190$

Total trip is 190 km.

Since already driven 152, to complete 190, you have to drive $190-152=38$ kilometers more.

So, 38 more kilometers to complete the trip.

Genius question: A long level railway bridge passes over a railroad track, which is 100 feet below it and at right angles to it.

nataly862011 [7]

Answer: 110 feet per second

Step-by-step explanation:

In this problem we will assume that the car at 45 miles per hour is moving into the x direction with a high of 100 feet, and the train is going in the y direction, so they trajectories will made an angle of 90º.

Now we can calculate the speed of the trains in feet per second so:

$S1=\frac{45*5280}{3600}=66$

$S2=\frac{60*5280}{3600}=88$

So we can make a right triangle with sides 66 and 88 and the hypotenuse will be the rate that the trains will separate per second so:

$h=\sqrt{66^{2} +88^{2} } =\sqrt{4356+7744}$

$h=\sqrt{12100}=110$

Is important to have in mind that the initial high is not going to change how fast the trains will separate, however, if we are going to calculate the distance we should have it in the calculations.
