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:
range means finding the slope value of the graph. :)
Answer:
7.5
Step-by-step explanation:
3 divided by 2/5
3*5/2=15/2=7.5
The negative 4 in the parenthesis caused the graph to move four units to the right.
The equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.
Step-by-step explanation:
Step 1; We need to determine the equation relating the x to the f(x) values from the given coordinates. y is the dependent value whereas x is the independent value i.e. y's value depends on x's value.
Step 2; If we multiply the x value with 2 and add the resulting answer with 1 we get the y value.
y = 2x + 1 is the equation that relates the values in the table.
Step 3; Now we substitute the values in the equation to see if it's correct.
For x = 0, y = 2(0) + 1 = 0 + 1 = 1,
For x = 2, y = 2(2) + 1 = 4 + 1 = 5,
For x = 3, y = 2(3) + 1 = 6 + 1 = 7.
So the equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.
