Answer:

Option: a is correct.

a .mean or median because there is no outlier

Step-by-step explanation:

Mean and median both try to measure the "central tendency" in a data set.

Clearly from the set of the values or data points:

{29 , 29, 29 , 28, 28, 27}

We could see that the data values are close too each other i.e. there is not outlier ( An outlier is a point that stand out of the rest points i.e. that value is either too high or low as compared to the other data points).

Here we have Mean=28.3333

and Median=28.5

Hence, the correct option is: option: a

a .mean or median because there is no outlier.

Triangle J K L is shown. Angle J K L is a right angle. An altitude is drawn from point K to point M on side L J to form a right

KiRa [710]

Answer:

$3\sqrt{5}\ units$

Step-by-step explanation:

<u>Theorem 1:</u> The height of right triangle drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of the altitude is the geometric mean of these two segments. Hence,

$KM^2=ML\cdot MJ\\ \\6^2=ML\cdot 3\\ \\3ML=36\\ \\ML=12\ units$

<u>Theorem 2:</u> In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of each leg of the right triangle is the geometric mean of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.

Thus,

$KJ^2=MJ\cdot ML\\ \\KJ^2=3\cdot (3+12)\\ \\KJ^2=3\cdot 15\\ \\KJ^2=45\\ \\KJ=\sqrt{45}=3\sqrt{5}\ units$
