Answer:
y = (-1/80)x^2 +2x
Step-by-step explanation:
The graph of the equation for the arch will go through the points ...
(0, 0), (160, 0), (80, 80)
We can start by making use of the zeros to write the function ...
y = a(x -0)(x -160)
To make the graph go through the point (80, 80), we must have ...
80 = a(80 -0)(80 -160) = (-80^2)a
-1/80 = a . . . . . . divide by the coefficient of "a"
So, our equation is ...
y = (-1/80)x(x -160)
y = (-1/80)x^2 +2x

Answer: The probability is 51.28%
Step-by-step explanation:
We know that out of 100% of the drivers, an 82% where stoped.
of these 84% stoped, 34% receive a blood test and 24% receive both tests, so a total of 58% received at least one test.
then, out of the 100% of the drivers, the ones that received at least a test are:
0.84*0.58 = 0.4872
So a 48.72% of the drivers received at least one test, this means that if one random driver is selected, the probability that the driver did not receive either test is 100% - 48.72% = 51.28%
Answer:
c = 6.5, a = 11.6
Step-by-step explanation:
2a + 3c = 42.7
3a + 5c = 67.3
Elimination
(2a+3c = 42.7)*3
(3a+5c = 67.3)*2
(1) 6a+9c = 128.1
(2) 6a+10c = 134.6
(2) - (1)
c = 6.5
Substitue 'c' in any of the equation
2a + 3(6.5) = 42.7 or 3a + 5(6.5) = 67.3
2a + 19.5 = 42.7 3a + 32.5 = 67.3
2a = 42.7 - 19.5 3a = 67.3 - 32.5
2a = 23.2 3a = 34.8
a = 11.6 a = 11.6
