Answer:
Per child admission costs $8.5
Per Adult admission costs $13.5
Step-by-step explanation:
Let x be the amount of admission per child and y be the amount of admission per adult
For Tom's party:
13x+2y=137.50 (Equation 1)
For Lisa's Party:
9x+2y=105.50 (Equation 2)
Using Elimination Method:
Add Equation 1 & 2
13x+2y=137.50
9x+2y=105.50
- - = - (Change of Signs)
---------------------------------
4x+0y=34.00
x=34/4
x=8.5
Putting the value of x in Equation 2
13(8.5)+2y=137.50
110.5+2y=137.50
2y=137.50-110.50
2y=27
y=27/2
y=13.5
Answer: I believe it is A
Step-by-step explanation:
In this table, you have to look at multiple things in the table. So you have to look at where it says Under 40 <em>and</em> that don't read the paper. So according to what I learned with this, you would have to do 36/40 and then get 0.9 which would be in percent form: 90 %.
I would recommend looking at another person's response also, before you submit this question. But hope this helps!
36%=36/100=9/25
36% of 125=9/25*125=45 :)
Answer:
the top left is a function
Answer:
False
Step-by-step explanation:
Residuals are the measure of the error in the fit. The square of their sum gives no weight to the sign of the error, but gives greater weight to larger errors. The fit will be better when the error is <em>smaller</em>. In this scenario, Line B is a better fit.
The statement that Line A better fits the data is FALSE.
