Answer:
{(0, −5), (2, 9), (−3, −26)}
Step-by-step explanation:
You only need to try the first point in each set to eliminate the wrong answers.
a: 7(-5)-5 = -40 ≠ 0
b: 7(2)-5 = 9 ≠ 7
c: 7(0)-5 = -5 . . . matches given point
d: 7(1)-5 = 2 ≠ 3
The third choice is the correct one: {(0, −5), (2, 9), (−3, −26)}.
Answer:
No
Step-by-step explanation:
The total number of trains is 287 + 54 + 17 + 5 = 363.
Of these, the number of trains that arrived no more than 10 minutes late is 287 + 54 = 341.
The proportion is p = 341/363 = 0.94.
94% of the trains arrived no more than 10 minutes late, so the company did not meet its target.
X = nr. hrs working for a farmer;
y = nr. hrs. babysitting;
x + y <= 25;
10x + 5y >= 150
a) Solve the system => one of the solution is x =5; y = 20(babysitting)
b) 10 + 12 =22 <= 25; 10*10 + 5*12 = 160 >=150.
