Hey there, standard deviation it's like a measure of numbers that's on a chart, as the numbers increase the higher the line increases. Here is an example.
Answer:
11 cars =21/2 hours
Convert 21/2 hours to minutes
60minutes =1hour
2.5 hours =150mins
11cars=150 mins
1 car =1/11×150mins=
150/11=13 7/11mins
7/11to seconds =60 seconds =1minutes
7/11×60secs =38secs
Answer =1car =13mins 38 secs

-21, -23, -27, -28, -28, -29 order them least to greatest and then find the middle if there is not a middle then put -27.5 as your answer for the median. For the mean add up all the number then you should get -156 then divide it by 6 which should give you -26 for the mean. and for the mode you should get -28 as the one that occurs the most often.
mean: -26
median: -27.5
mode: -28
The length of the line segment BC is 31.2 units.
<h2>Given that</h2>
Triangle ABC is shown.
Angle ABC is a right angle.
An altitude is drawn from point B to point D on side AC to form a right angle.
The length of AD is 5 and the length of BD is 12.
<h3>We have to determine</h3>
What is the length of Line segment BC?
<h3>According to the question</h3>
The altitude of the triangle is given by;

Where x is DC and y is 5 units.
Then,
The length DC is.

Squaring on both sides

Considering right triangle BDC, use the Pythagorean theorem to find BC:

Hence, the length of the line segment BC is 31.2 units.
