What is a Venn Diagram ?

Diagrams which represent pictorial relationship of information are called Venn Diagrams. It is used to study sets. It was first used by John Venn

The complete question is

A group of campers were polled about whether they like swimming and whether they like playing baseball. The data from the survey is shown in the Venn diagram. Use the Venn diagram to find the missing values in the frequency table. A circle labeled swimming 24 overlaps a circle labeled baseball 18. Overlap is labeled 15. 4-column table with 3 rows. First column has no label with entries likes baseball, does not like baseball, total. Second column is likes swimming with entries a, c, 39. Third column is does not like swimming with entries b, 13, e. Fourth column is labeled total with entries 33, d, 70.

Which values are correct? Select three options. a = 15 b = 18 c = 23 d = 35 e = 31

The image of the Venn Diagram is attached

From the Venn Diagram we can calculate the value of a, b , c , d and e

People who like swimming and baseball = a = 15

People who do not like swimming likes baseball = b =18

People who like swimming and do not like baseball = c = 24

total =  d = c + 13 = 24+13 = 47

e =70-39 = 31

Therefore the values of a, b and e are correct.

The area of a rectangle is 14 m2 , and the length of the rectangle is 3 m less than double the width. find the dimensions of the
muminat
Width =3.5, length = 4

Let's make a few equations to summarize what we know.:
a = 14
l = 2w -3
a = wl

Now let's substitute the expression for l into the expression for area and solve.
a = w(2w - 3)
a = 2w^2 - 3w
14 = 2w^2 - 3w

0 = 2w^2 - 3w - 14

which factors into
(2w - 7) (w + 2)

Solving for w
2w - 7 = 0
2w = 7
w = 3.5

w+2 = 0
w = -2

So w can be either 3.5 or -2. Since a negative width doesn't make sense, w = 3.5

Let's verify
w = 3.5
l = 2w - 3
l = 2*3.5 - 3
l = 7 - 3
l = 4
a = wl
a = 3.5 * 4
a = 14

So the width is 3.5 and the length is 4.

Answer:

x = 1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x−

=3

4x+−1=3

4x−1=3

Step 2: Add 1 to both sides.

4x−1+1=3+1

4x=4

Step 3: Divide both sides by 4.

4x

How do I solve this problem using the substitution method <br> x-3y=4<br> 4x-2y=26
Nastasia [14]
Top 1. Substitute 3y on both sides of the equation.
Bottom 2. Substitute 2y on both sides of the equation

3y and 2y cancel

Divide x by 4 and 26 by 4.
