Answer:

85%

Step-by-step explanation:

Let’s identify all the outcomes less than 10, that would be 2-9

The number of times the die was rolled is obtainable by adding all the frequencies ;

That would be ;

3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 + 9 + 5 + 1 = 100

Now let’s add the frequencies of results which are less than 10;

That would be the frequencies of the numbers 2-9;

Thus, we have;

3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 = 85

The required probability of rolling a number less than 10 = 85/100 = 0.85 which to the nearest percent is 85%

The question was incomplete. Below you will find the missing content.

In the figure below, BL, AM, and CK are medians of △ABC. If KC = 108 and OC = 2n + 10, then n=

The picture is attached below.

The value of n is 31.

The median is the line connecting the vertex and its midpoint on the opposite side of the triangle.

The intersection of all 3 medians of the triangle is called the centroid.

As we know centroid divides the median in the ratio of 2:1.

In the given picture,

Medians of triangle △ABC are AM, BL, and CK.

So the centroid of the triangle is O.

Given that KC= 108

As the centroid O divides the line KC in 2:1.

Let OC=2x

KO= X

As KC= KO+OC

⇒ 108= x+2x

⇒ 3x=108

⇒ x=108/3

⇒ x=36

Then OC= 2x= 2*36= 72

As given in the question OC= 2n+10

putting the value of OC in above equation

⇒ 72= 2n+10

⇒ 2n= 72-10

⇒ 2n=62

⇒ n=62/2

⇒n=31

Therefore the value of n is 31.
