Answer:
198 students walk to the local high school
Step-by-step explanation:
Total number students = 825
1/5 of the students travel by car
48% of the students travel by bus
0.08 of the students travel by bicycle
To find the number of students who wal to school we have to find the exact number of students who travel to school by car, bus and bicycle and subtract the result from the total number of students
Students who travel by car = 1/5×825
= 165 students
Students who travel by bus = 48% × 825
= 48/100 × 825
= 12/25 × 825
= 396 students
Students who travel by bicycle = 0.08 × 825
= 66
So now we add the results fo the equations above and subtract it from the total number of students to get the number of students that walk to school
Students that walk to school = 825 - (165 + 396 + 66)
= 825 - 627
= 198 students
Therefore 198 students walk to the local high-school

Still don't know what the given line is, so I'm just going to attach images of the graphs of each equation.
Graph 1: y = -2x
Graph 2: x = 4
Graph 3: y = x
Graph 4: y = 3
Hope this helps!
In the problem. N+1=4(n-8)... the main goal is to isolate the variable(n) so, I would first distribute 4.. thus meaning 4•n + 4•-8=4n + - 32.... this works because of the distributive property. This would leave u with 4n + -32=n +1.... seeing that there was like terms in both side of the equation... I can cancel the n out of the other side; 1= (4n-n) -32, which is the same as 1=3n-32.... you can do the same with the whole numbers.... cancel the -32 out of one side by adding 32 to both sides; 33=3n and then easily u can find that 3•11= 33 so n=11
Answer:
0.7448
Step-by-step explanation:
P(A1) =0.95
P(A2) =0.98
P(A3) =0.8
We have to find P( all three components function properly)=P(A1∩A2∩A3).
We know that the these three events are independent so,
P( all three components function properly)=P(A1∩A2∩A3)=P(A1)*P(A2)*P(A3)
P( all three components function properly)=P(A1∩A2∩A3)=0.95*0.98*0.80
P( all three components function properly)=P(A1∩A2∩A3)=0.7448
