Answer:
59
Step-by-step explanation:
5: 30 pm is 2.5 hours after 3 : 00 pm
Substitute x = 2.5 into the equation
y = - 6.2(2.5)² + 41.5(2.5) - 5.6
= - 38.75 + 103.75 - 5.6
= 59.4
The average number of cars is 59
X+y=30
2x-3y=5
y=30-x
2x-3(30-x)=30
2x-90+3x=30
5x=120
x=24
y=30-x
y=30-24
y=6
The positive difference between the two numbers is 18.
F(-4)=11...because x is less than 3, you use the top one.
There is no illustration attached to this question, so it is impossible to answer it. I apologize.
Just add them all up and divide by how many numbers there are
6+12+22+16=56
56 divided by 4 = 14
14 is the mean
