Let there be a advanced tickets and s same day tickets, Then:-
a + s = 40
20a + 30s = 950............................(1)
Multiply first equation by -30
-30a - 30x = -1200 .....................(2)
Adding equations (1) and (2):-
-10a = - 250
a = -250/-10 = 25
So s = 40 - 25 = 15
Answer:- advanced tickets cost $25 and same day cost $15.
You probably just need to simplify the expression. To do this you just combine like terms. So you would subtract 38 from the 10 to get -28x and then subtract 47 from 36 which gives you -11. Your expression should be -28x-11.<span />
Answer:
If A=10, then 2a+3=23
Step-by-step explanation:
2x10=20
20+3=23
The <u>correct answer</u> is:
<span>c) Each point in the data set is near the regression line.
Explanation:
A best fit regression line is the line that most closely approximates the data. This means that the line must be near most of, if not all, of the points of the data set.
If this truly is the line of best fit, the points of the data will be near the line.</span>
Answer:
2
Step-by-step explanation:
The distances have the ratio:
(C -A) = (2/3)(B -A)
C = (2/3)B +(1/3)A . . . . . add A
C = (2B +A)/3 . . . . . . . . combine terms
C = (2(4) +(-2))/3 = 6/3 = 2
The coordinate of C is 2.
