The tail of a 1-mile long train exits a tunnel exactly 3 minutes after the front of the train entered the tunnel. If the train i

igomit [66]

The tail of the train starts one mile from the mouth of the tunnel and it must travel that distance plus the length of the tunnel in 3 minutes.

Let t = tunnel length

t + 1 = distance the tail must travel in 3 minutes.

3 minutes = 1/20 hr

(t+1) miles / 60 m/hr = 1/20 hr

t + 1 = 60/20

t+1 = 3

Subtract 1 from each side:

t = 2

The tunnel is 2 miles long.

No, because if the angles are the same the length is the same too. It is a scalene, obtuse triangle if you need that as well.

Which statements are true about the median of a data set?

Leto [7]

Answer: Third and fifth option

3) The median is the number in the middle on an ordered set of data.

5) To find the middle of an even data set, find the average of the two middle numbers.

Step-by-step explanation:

Given a set of data ordered from lowest to highest, the median of the data is the number that is in the middle. In other words, it is a number x for which it is true that 50% of the data is greater than x and the other 50% of the data is less than x.

For example, for the following set of 7 data:

2, 3, [5], 8, 13

the median is 5.

If the data number is even, for example 10 data:

3, 5, 9, 12, [19, 21], 33, 35, 40, 69

The median is the average between the two data that are in the middle

$\frac{19 +21}{2} = \frac{40}{2} = 20$

Note that the median only represents a partition of the ordered data set. Therefore, it is not affected by outlier. For example

2, 4, 4.5, 4.8, 5 Median = 4.5

2, 4, 4.5, 67, 1506 Median = 4.5

The median does not represent the difference between the highest and the lowest data.

Therefore the correct affirmations are:

3) The median is the number in the middle on an ordered set of data.

5) To find the middle of an even data set, find the average of the two middle numbers.

Below are two parallel lines with a third line intersecting them. Help me on this Geometry transversal angle!!

Neporo4naja [7]

Answer:

56 degrees

Step-by-step explanation:

So those angles are called alternate exterior angles because they happened at the difference intersections along the transversal on opposite sides of that transveral while on the outside of the lines that the transversal goes through.

If these lines that the transversal goes through are parallel then the alternating angles are congruent.

So they are because of the little >> things on those lines.

So x=56 degrees
