Answer:
C
Step-by-step explanation:
the lines are intersecting at 1,3
No one is obtouse and one is acute
The equation that relates x and y :
y = kx , where k is the proportionality constant.
For given question,
y varies directly as x
Also, y= 12.4 when x= 4
So, for x = 1 the value y is,
y = 12.4/4
y = 3.1
As y is directly proportional to x, the equation that relates x and y is,
y = kx
where k is the proportionality constant.
We know that when two values or quantities are directly proportional to each other then one value decreases at the same rate that the other increases.
Therefore, the equation that relates x and y :
y = kx , where k is the proportionality constant

23) 84% of a contractor’s jobs involves electrical work. 75% of a contractor’s jobs involve plumbing work. Of the jobs that involve plumbing, 90% of the jobs also involves electrical work. Let E = jobs involving electrical work L = jobs involving plumbing work Suppose one of the contractor’s jobs is randomly selected. Using the sixth Excel worksheet, a) Find P(E). 0.84 b) Find P(L). 0.75 c) In words, what does E | L mean? d) Find P(E | L). e) Find P(E and L). f) Are E and L independent events? Why or why not? g) Find P(E or L). h) Are E and L mutually exclusive? Why or why not
Step-by-step explanation:
you find that lines slope with points (4,1)and (0,4) so you do 4-0=4 ad 1-4=-3 so the slope is -3/4 for the line shown so the line we needs slope will be the opposite recipricole so 4/3 and to get the equation you have to plug everything in first 4=(4/3)5+b so that we can find b ( the y intercept)
4=6 2/3 +b
2 1/3=b
the equation is y=4/3+2 1/3
