Therefore,

The table that represents the survey conducted by Isabel is:
Like Dolls Don't like Dolls Total
Like Trains 40 15 55
Don't like Trains 17 8 25
Total 57 23 80
<h3>How can the table be filled? </h3>
The total number of kids that like dolls = total number kids - total number of kids that don't like dolls
80 - 23 = 57
Number of kids that don't like Trains but like dolls = total number kids that like dolls - Number of kids that like Trains and dolls
57 - 40 = 17
Number of kids that don't like dolls and but like trains :
30% x 23 = 7
(23 - 7) /2 + 7 = 15
Number of kids that don't like dolls and trains = (23 - 7) / 2 = 8

4x = 0
x = 0
So the solution to the system of inequalities is (0,5)
Answer:
19.019
Step-by-step explanation:
Let's solve this problem using the order of operations, or PEMDAS.
0.019 + (2.3 × 10 - 4) = 0.019 + (23 - 4) = 0.019 + 19 = 19.019
Hope this helps!
