The Venn diagram is given below. Then the number of students who have brother and sister will be 6.
<h3>What are sets?</h3>
A set is a group of clearly specified components. The number of items in a finite set is denoted by a curly bracket.
In a class of 20 students:
11 have a brother, 9 have a sister, and 6 have neither.
Then the Venn diagram will be
11 – a + a + 9 – a = 20 – 6
20 – a = 14
a = 6
The Venn diagram is given below.

Answer:
17
Step-by-step explanation:
3 + 7 * 6 / 3
PEMDAS says we multiply and add before adding and subtracting so we multiply first (going from left to right)
3 + 42 / 3
Then we divide
3 + 14 = 17
The y intercept (when x=0) is 40
the slope is 15 ( slope= rise/run= 15/1=15)
therefore, the equation of the line is y=15x+40
Answer:
GCF of 32 and 80 is 16
Step-by-step explanation:
factors of 32 = 1, 2, 4, 8, 16, 32
factors of 80 = 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
