What is the mean of 13,6,8,6,15
Luden [163]

Hey there!

To start, the mean of the answer is also known as the average value of a set of numbers. This is calculated by dividing the sum of the set by the total amount of numbers.

In this case the sum of all the numbers is 13 + 6 + 8 + 6 + 15 which is equal to 48.

Now, divide 48 by the total number of numbers in the set: 48/5 = 9.6

Your final answer should be 9.6, or you can leave it in fraction form as 48/5.

Hope this helps!

vlada-n [284]

Answer:

21.5 km

Step-by-step explanation:

We have to find the distance  between two boat

We are given that

AC=2.1 km

BC=3.5 km

We have to find BC

The angle between two boat =110 degrees

Using cosine law

BC=\sqrt{(2.1)^2+(3.5)^2-2\cdot(2.1)\cdot(3.5)cos 110}

BC=\sqrt{4.41+12.25+ 2\cdot2.1\times3.5cos 70

BC=\sqrt{4.41+12.25+9.3051}

BC=21.507 km

Hence, the distance between two boat is 21.5 km
