Answer:
(0,5) (1/2, -1) (1, 3)
Step-by-step explanation:
We basically plug in all of these points.
(0,0) --> 0=8(0)-5 <-- This is not true, because 0 ≠ -5
(0,5) --> -5=8(0)-5 <-- This is true, because -5 = -5
(1/2, -1) --> -1=8(1/2)-5 <-- This is true because -1 = -1
(8, -5) --> -5=8(8)-5 <-- This is not true because -5 ≠ 59
(1, 3) --> 3=8(1)-5 <-- This is true because 3 = 3
It's C)
the graph is decrasing, so the variable rate is negative (-2/3)
the rest was quite easy, you just take a look at where the graph cuts the y-axis and determine the rest from the rate of going up or down (increase/decrease)
We need to find the probability of atleast one failure in 5 trails
Probability of success = 30% = 3/10
The opposite meaning of atleast one failure is all success (no failures)
Probability of (atleast one failure ) = 1- Probability ( success)
First we find probability of success
Formula for binomial distribution
All success so n=5, r=5, p= 3/10, q= 1-p = 7/10
Probability (success) =
=
Probability (atleat one failure) = 1 -
= 0.92224
= 92.2%
