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.
Answer:
0.973
Step-by-step explanation:
Given the following :
Population mean (μ) = 185
Standard deviation (σ) = 26.7
Sample mean (m) = 177.6
Sample size (n) = 48
P(m > 177.6)
Z = (m - μ) / σ/√n
Z = (177.6 - 185) / (26.7/√48)
Z = −1.920176
P( z > - 1.920) = 1 - p(z < - 1.92)
Using the z table :
1 - p(z < - 1.920) = 1 - 0.0274 = 0.9726
= 0.973

Answer:
Step-by-step explanation:
Every 24 additional page of the book adds an additional millimeter to its thickness. This means that additional 48 pages of the book would add millimeter to its thickness and 72 pages would add additional 3 millimeter to its thickness. Therefore, if the book contains 600 pages, the additional millimeters added to the thickness of the book would be
600/24 = 25mm
Since the front and back covers are 5mm thick each, the total thickness of the book would be
25 + 5 + 5 = 35 mm
The answer is 50 Sq In.You are right.Hope it helps and have a good day!
