(a) The proportion of accidents that occur up to mile 1.2 of the path is the area under the density curve between 0 miles and 1.
inn [45]

Answer:

the area would be 0.4 or 40%

Step-by-step explanation:

The computation of the area is given below:

But before that the level of the density is

The density level is

=  1 ÷ (3 - 0)

= 1 ÷ 3

Area from 0 miles to 1.2 miles

= (1 ÷ 3) × (1.2 - 0)

= 0.4 or 40 %

Hence, the area would be 0.4 or 40%

the same is considered and relevant too

100 points!!! i will award brainliest!! Lines AB, and CD are straight lines. Find x and y
Ket [755]

<O = 16 degrees   vertical angles are equal


<O + 4x+90 = 180   DC is a straight line

16 +4x +90 = 180

106 +4x = 180

4x =74

x =18.5


16 +90  +2y= 180   DC is a straight line

106+2y=180

2y = 74

y= 37

Answer : y=37

Please solve for all three parts of the question.
neonofarm [45]

Answer:

f(-5) = 25

f(0) = -2

f(5) = 16

Step-by-step explanation:

Given the functions;

To get f(-5), we will use the function of x where x is less than 0 since -5 is less than zero

at where x < 0, f(x) = x^2

f(-5) = (-5)^2

f(-5) = 25

b) For f(0), where the point where x = 0, f(x)= -2

Hence the value of f(o) = -2

c) For f(5), the function where x > 5 is f(x) = 2x+6

f(x) = 2x+6

f(5) = 2(5)+6

f(5) = 16
