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

Shoshanna is not correct
to find if a right triangle is actually a right triangle you have to do the two smaller values squared equals the larger value squared
(a²+b²=c²)
correct way to solve this problem:
a²+b²=c²
8²+15²+17²
64+225=289
289=289
so, this triangle is a right triangle
Answer: y = -1/2
Step-by-step explanation:
Subtract both sides by 7/8
y = 3/8 - 7/8
Then combine like terms
y = -4/8
Then simplify
y = -1/2
Answer: x equals 9
Step-by-step explanation: The figure in the question is a Rhombus and one of the properties of a rhombus states that “the diagonals bisect each other.”
This means line SU bisects line TV into two equal parts at point W. This also means that line WV is half of line TV. If line TV equals 74 and line WV equals 4x + 1, then we have the following;
(4x + 1) x 2 = 74
4x + 1 = 74/2
4x + 1 = 37
Subtract 1 from both sides of the equation
4x = 36
Divide both sides of the equation by 4
x = 9.

Answer:
t = 
Step-by-step explanation:
First, you need to complete the -3 + 1 and then expand the brackets
-3 + 1 = -2
7t -2 - (-2) = -3(1 - 3t)
Now expant the -3(1 - 3t) bracket
-3 * 1 = -3
-3 * -3t = 9t
7t - 2 - -2 = 9t - 3
The two negatives turn positive:
7t - 2 + 2 = 9t - 3
7t = 9t - 3
Move the -3 over to the oposite side, and also move the +7t over to the +9t, making it a negative:
3 = 9t - 7t
3 = 2t
Divide both sides by 2:
t =
So the value of t is
