Answer:
B) 0.45
Step-by-step explanation:
The total number of students is:
4 + 5 + 4 + 6 + 10 + 8 + 2 + 1 = 40
The number of students with brown hair is 10 + 8 = 18.
So the probability is:
P = 18/40 = 0.45
Answer:
22 8/11
Step-by-step explanation:
= 250/11
= 22 8/11
First we have to assume that each quarter touched each other. Hence the area of the table not covered by the coins (A) is equal to the total area of the table (At) minus the total area of the coins (Ac). Coins are circle, so

and r =24.26mm. The area of one coin is then 1848.98mm^2. Hence the equation is A = At - xAc where x is the number of coins.
Hello there!
"Compare the fraction 3/5 to 1/2 and then compare 2/6 to 1/2. Use symbols in your answer"
To make this easier, we will make it so that both fractions in each pair has like bases.
To make 3/5 and 1/2 have a like base, we must make the denominators 10. To do this, we will do the following:
(3*2)/(5*2) = 6/10
(1*5)/(2*5) = 5/10
Now we can easily compare and not worry about the denominator
So, let's just look at the numerators.
Which is greater, 5 or 6? We know 6 is greater, so:
6/10 > 5/10
That means:
3/5 > 1/2
Now, we must do the same for 2/6 and 1/2
We will make them both 6. So, we can leave 2/6 alone
2/6
(1*3)/(2*3) = 3/6
Now we have 2/6 and 3/6
Which is greater, 3 or 2. The answer to that is 2. So:
3/6 > 2/6
This means that 1/2 > 2/6
Our answers are:
1. 3/6 > 2/6
2. 1/2 > 2/6
I hope I was able to help you!
