Answer:
m = -2
Step-by-step explanation:
To find the slope of a line, use the equation:
m = y2 - y1 / x2 - x1
Then, substitute in values:
m = 54 - 58 / 2 - 0
m = -4 / 2
m = -2
Let b be the initial amount of books. Steve sells half of his books, so the number of Steve's books become
Then, he buys 6 more, so the number increases by 6:
This number is now 14, so you have
Subtract 6 from both sides:
Multiply both sides by 2:
Its easier to find the complement of that instead
so you find the probability of 1 and 0
The .2 in the answer is the probability of each question 1/5
(10 C 0) x .2^0 (1-.2)^10-0=.1074
(10 C 1) x .2^1 (1-.2)^10-1=.2684
.2684+.1074=.3758 and that's the complement
so 1 - .3758= .6242
I too have a stats exam on this tomorrow lol
