Answer:
A ∩ B = {1, 3, 5}
A - B = {2, 4}
Step-by-step explanation:
The given problem regards sets and set notation, a set can simply be defined as a collection of values. One is given the following information:
A = {1, 2, 3, 4, 5}
B = {1, 3, 5, 6, 9}
One is asked to find the following:
A ∩ B,
A - B
1. Solving problem 1
A ∩ B,
The symbol (∩) in set notation refers to the intersection between the two sets. It essentially asks one to find all of the terms that two sets have in common. The given sets (A) and (B) have the values ({1, 3, 5}) in common thus, the following statement can be made,
A ∩ B = {1, 3, 5}
2. Solving problem 2
A - B
Subtracting two sets is essentially taking one set, and removing the values that are shared in common with the other set. Sets (A) and (B) have the following values in common ({1, 3, 5}). Thus, when doing (A - B), one will omit the values ({1, 3, 5}) from set (A).
A - B = {2, 4}
Answer:
subtraction= Mike is selling 50 apples. Kenny is selling 30 apples,"how many more" apples does mike have than ken?
50- 30 = 20
mike has 20 "more" apples than ken.
there are 15 kindergarteners, "but only" 10 chairs, "how many" chairs would the teachers have to "take away" from the room next door?
15- 10=5
Answer:
Step-by-step explanation:
The area of the circle is 
The area of the triangle is 
Hence, the probability of a randomly selected point within the circle falls in the red shaded area is 
Answer:
<h2>1525.7 square meters, approximately.</h2>
Step-by-step explanation:
Notice that the radius is 28 meters, and the angle of the orange sector is 137°. However, the angle of the blue sector is:
360° - 137° = 223°
The area of a circular sector is
Replacing given values, we have
Therefore, the right answer is the second choice.
<u>Dana : she works 4 days and gets paid $ 12.75 per dog...and she grooms 15 dogs per day.....so Dana makes : 4(12.75 * 15) = 4(191.25) = $ 765</u>
<u>Monique : she works 5 days and gets paid $ 12.75 per dog...and she grooms 10 dogs per day....so she makes : 5(12.75 * 10) = 5(127.50) =</u>
<u>$ 637.50</u>
<u>so the difference between their weekly earnings is : (765 - 637.50) =</u>
<u>$ 127.50 </u>
