It says that mean of six nos is 4.7
So, that means ( no pun intended), the average of six numbers give a value of 4.7
the same goes for the average of the other four numbers=6.5
If we're talking about the mean ( average) of all the ten numbers , we usually would need the ten numbers ( their values and their frequency) , but since its already given as mean itself , we could just add up the values.
4.7+6.5=11.2
A lunette is a semi-circle, which means that it is one half of a circle. To find its area, we can find the area of the whole circle and divide it by two.
Area of a circle: A = pi x r^2
r = 40 / 2 = 20
A = pi x 20^2
A = 400pi / 2 = 200pi
200pi = 628.32
The area of the lunette is approximately 628 in^2.
Hope this helps!! :)

Step-by-step explanation:
if I'm right plz give me brainliest
First off, add 3 to both sides of the equation.
6n - 3 + 3 > -18 + 3
Then, your equation should look like this: 6n > -15
Next, divide both sides by 6.
6n/6 > -15/6
Your answer is n > -5/2
