Answer:
1/2
Step-by-step explanation:
So we know that there is a total of 10 people.
5 of these have grey hair.
To find the chances of a somone having grey hair, we need to divide people with grey hair over total people:

This is the same division we use to find things such as percentage and ratio as well.
Now lets plug in our numbers and solve:

So half of the people have grey hair.
Or(in percentage):
The probability is 50% that someone will have grey hair.
Hope this hepls!
Can you post original picture of question please
I believe number one is 1400
Answer:
x= 9.04°
7x = 63.28°
8x = 72.32
44.4° + 63.28° + 72.32° = 180°
Step-by-step explanation:
The sum of supplementary angles is 180°
Set up an equation with the given information, then solve for x.
44.4 + 7x + 8x = 180
7x +8x = 180-44.4
15x = 135.6 Divide both sides by 15
x = 9.04
Substitute for x and multiply by 7, then 8 to find the measures of the unknown angles.
