The value of C=1/3 for the probability density function f(x)=cx , 0<x<2.
<h3>What is probability density function?</h3>
The probability density function is a function of a continuous random variable, whose integral across an interval gives the probability that the value of the variable lies within the same interval.
Given that:
Here we can see that the value of x is varies as 0,1,2
So at 0,1,2 the value of the function is
So the probability density function is given as:
Hence the value of C=1/3 for the probability density function f(x)=cx , 0<x<2.

Let's write down what we know:
a=50+b
b=30+c
After one hour:
(a+50)*2=-70+3*(c+50)
let's eliminate the brackets:
2a+100=-70+3c+150
2a+100=+3c+80
which is:
2a=-20+3c
substituting from a=50+b:
100+2b=-20+3c
substituting from b=30+c
100+2(30+c)=-20+3c
100+60+2c=-20+3c
160+20=3c-2c
180=c.
So we know that c is equal to 40, then b will be b=30+c
b=30+180=210.
So B had 210 miles initially.
Answer:
(0,2)
Step-by-step explanation:
Basically, the x coordinate is non-existent, so it is a 0. The y is 2. So the coordinates are (0,2). The line you graph should be a horizontal line on the y-axis.
Sorry if my explanation didn't make sense but I'm positive my answer is correct.
(A) 4(x+5). Distribute the 4 (multiply both numbers by 4) and you get
4x+4*5
4x+20
(B) 70 km/h * y hours is 70y km, because you traveled 70 km every hour, so it's 70 times y.
