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!

Answer:
The actual area of the dog house floor is 1,440 in²
Step-by-step explanation:
step 1
Find the actual dimensions of the house floor
The scale is equal to
4 in/ft
Divide the dimensions of the plan by the scale
16 in=16/4=4 ft
10 in=10/4=2.5 ft
step 2
Convert ft to in
Remember that
1 ft=12 in
so
4 ft=4*12=48 in
2.5 ft=2.5*12=30 in
step 3
Find the actual area of the dog house floor to the nearest tenth inch
A=48*30=1,440 in²
Anyways the ratio of the independence is the five points he was the ratio amount of
To find the number you should start by writing out an equation using x as the number you don't know. That would be 16-3x=7. You would start solving that equation by subtracting 16 from both sides, making the new equation -3x=-9. Finally, you would divide both sides by -3, giving you the answer of x=3.
