Given that the bag contains 5 apples and 3 oranges, if you select 4 pieces of fruit without looking, the number of ways you can get 3 apples is given by:
we can select 3 apples in 5C3 ways but we are selecting 4 pices, this means that one orange can be selected in 3c1 ways. Using product rule, the total ways to select four pices is
5C3*3C1
=5!/[3!*(5-1)!]×3!/[1!(3-1)!]
=120/(6×2!)*6/(2!)
=12×3
=36
Answer:
39
Step-by-step explanation:
Let the number be x.
The quotient of x and 3 is 13.
x/3 = 13
Multiply both sides by 3.
x = 13 × 3
x = 39
You need to list all of the possible outcomes. For example, Ham and Turkey, Ham and Lettuce, and so on. Make sure you list all of them. You will probably find that there is 42 in total. But, this is not an answer choice so what do you do? There will be doubles like when you say Ham and Turkey, you'll eventually say Turkey and Ham. But since you already listed the two, do not count Turkey and Ham. I hope this helps you!
Answer:
10026 m²
Step-by-step explanation:
Since there are two semicircles attached to the rectangle, we can just say that that is one circle.
1. The area of the rectangle:<em> length * width = 60 * 120 = 7200 m²</em>.
2. The area of the circle: πr²
a. The radius of the circle: Since the circle is attached to the end of the rectangle, that means that the diameter would be the same length as the width. So, it would be 60 m, therefore, <em>the radius is 30 m</em>.
b. πr² = 3.14*30² = 3.14*900 = <em>2826 m²</em>.
3. Total: 2826 + 7200 = 10026 m².
