Answer:
444 adult ticket
763 student ticket
Step-by-step explanation:
let a = number of adult ticket
let s = number of student ticket
s+a=1207
5a+s=2983
get s by itself in the 1st equation so you can plug it into the 2nd
s+a=1207
-a -a
s=1207-a
5a+(1207-a)=2983
solve for a
4a+1207=2983
-1207 -1207
4a= 1776
444
this is adult ticket amount
subtract this from 1207 to get student amount
1207-444=763
False, because there is not enough information to prove that it is true
hope this helps

Step-by-step explanation:
P( at least 8 correct ) =
<span>........P( 8 ) + P( 9 ) + P( 10 ) = </span>
<span>........(10 C 8).5^10 + (10 C 9).5^10 + (10 C 10).5^10 = ........56*.5^10 = 0.0546875 </span>
<span>Note: Let C denote correct and I denote incorrect. Suppose that guessing results in 8 correct and 2 incorrect answers. One possible outcome is CCCCCCCCII, for example. We can think of the number of ways of getting exactly 8 correct to be the same as the number of ways of selecting 8 spots for the correct answers times the number of ways of selecting two spots for the remaining two answers. There are (10 C 8) ways to select the positions for the correct answers and precisely one way to select the remaining two positions for the incorrect answers. Therefore, there are there are 10 C 8 = 45 ways to get 8 correct. Similarly, there are 10 C 9 = 10 ways to get 9 correct, and 10 C 10 = 1 way to get all 10 correct.</span>
Answer:
three small smoothies require one and one-third bananas.
Step-by-step explanation:
Assuming that the three small smoothies are equal, and their sum equals the one large smoothie;
Number of bananas required for one large smoothie = three and three-third
three-thirds mean that out of three parts, three parts were selected. Therefore, three-thirds is the same thing as a whole or 1
∴ three and three-third 
Therefore, the one large smoothie required 4 bananas.
Large smoothie = 4 bananas
three small smoothies 
Hence, three small smoothies require one and one-third bananas.
