Step 1: 8g+24^3=8
Step 2: 8g=8-24^3
Step 3: g=(8-24^3)/8
Answer: -1727
Answers:
0.45 is a moderate association
0.95 and -0.8 are both strong association
0.10 is weak association
Explanation:
This is the interpreation of the correltaion coefficient:
1) The correlaion coefficient assesses the relationship between two variables in a scatter plot.
2) If the sign of the correlation coefficient is positive means that the two variables trend to grow or decrease in the same sense. This is an uphill line or curve: if variable X grows, variable Y grows, and if variable X decreases variable Y grows.
If the sign of the correlation coefficient is negative means that the two variables go in opposite direction. This is a downhill line or curve.
3) A correlation coefficient of +1 or -1 is a perfect association. The two variables are totally associated.
4) A correlation coefficient less that +1 but greater than 0.7 is a strong association. The same with a coefficite between - 0.7 and -1.
5) A correlation coefficient arroun +0.5 or -0.5 is a moderate association.
6) A correlation coefficient of 0 is a nill association.
7) A correlation coeffiicient between 0 and 0.3 is a weak association. The same when the correlation coefficient is between -3 and 0.

Answer:
14 children went to the movies and 18 went to the pool.
14 niños en el grupo del cine y 18 en el grupo de la piscina.
Step-by-step explanation:
We can solve this question using a system of equations.
I am going to say that:
x is the number of children that went to the movies.
y is the number of children that went to the pool.
Class of 32:
This means that 
To go to the pool, it costs 2.5 euros. To go the movies, it costs 3.5 euros. 94 euros were spent.
This means that 
From the first equation:
Replacing in the second
14 children went to the movies and 18 went to the pool.
14 niños en el grupo del cine y 18 en el grupo de la piscina.
