Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of adult tickets
y ----> number of children tickets
we know that
Jane sold 100 tickets for her school auction
so
----> equation A
Jane collected a total of $944
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (36,64)
see the attached figure
therefore
The number of adult tickets sold was 36 and the number of children tickets sold was 64
Answer:
1/3
Step-by-step explanation:
The attachment shows a table with the given information filled in. Since we know 53 chose football and 23 chose tennis, the remaining 38 must have chosen running.
Then 38 out of 114 students chose running. The probability that one of those is picked at random is ...
p(running) = 38/114 = 1/3
Answer:
