1/ 816
Step-by-step explanation:
Step 1 :
Given
Total number of students in the school = 18
Number of students randomly selected = 3
Step 2 :
Number of ways in which 3 students can be selected out of 18 students is
C(18,3) = 18! /(3!(*18-3)!) = 18*17*16/3*2*1 = 816
Number of ways in which 3 students are selected and they are the youngest = 1
Hence the probability of selecting 3 youngest students from the available students is 1/ C(18,3) = 1/ 816
The opening of the jar is a circle.
The area of any circle is (pi) x (radius)²
What's the radius of the jar ?
Well, the diameter is 5 inches.
Radius = 1/2 of the diameter = 2.5 inches.
So Area = (pi) x (2.5 inches)² =
(3.14) x (6.25 square inches) = <em>19.625 square inches</em>.
Answer:
When using a fraction, write the number over the whole number.
So:
4/13
2/8 = 1/4
10/12 = 5/6
When making a ratio with a :, include the two different parts that would add up to make the total, starting with the one mentioned first.
So:
4:9
2:6
10:2
Writing a ratio with the word "to" is the same as using a colon, except you usually want to include what each is.
So:
4 tulips to 9 daffodils
2 days to 6 days(?Dont have context, so write what you know?)
10 yellow eggs to 2 colored eggs
Answer:
A
Step-by-step explanation:
6 + 13 = 19, this is TRUE.
So x = 6 In x + 13 = 18 would be FALSE.
The answer is A. No, because 6 + 13 = 18 is not true.
