Answer:
1/3
Step-by-step explanation:
Probability of solving ten problems by Carl
Given
Total number of problems = 20
Number of problems studied by Carl = 15
Number of problems out of the 20 set of problem coming in test is 10
Case I - All ten problems come from the set of known 15 question
10/15 * 10/20 = 1/3
Get a graph and draw the points
Answer:
y=1/3x+4
Step-by-step explanation:
y=mx+b
(0,4) and (-4,-8)
use the slope formula to find the slope between these two points:
(-4-0)/(-8-4)
the slope is 1/3.
y=1/3x+b
plug in one of the points. I used (0,4).
4=1/3(0)+b
4=b
y=1/3x+4
