Students at a high school were asked about their favorite outdoor activity.
The results are shown in the two-way frequency table above.

Select ALL STATEMENTS that are true based on the given table.

1. More students chose camping as a favorite outdoor activity in the combined number of students who chose canoeing or skiing.

2. There were more boys surveyed than girls.

3. More girls chose camping as their favorite outdoor activity than boys.

4. More boys chose skiing as their favorite outdoor acivity than girls.

5. Twice as many students chose canoeing as their favorite outdoor activity than those who chose fishing.

6. More girls chose canoeing as their favorite outdoor activity than those who chose skiing.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

i think the amount would be $140.62

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
