The line is given in the form:

Where

is the slope and

is the y-intercept.
Comparing the given line to the generic form we can see that

, which is the slope.
You could also get this/check the answer by graphing the equation.
Answer:
0.7633
Step-by-step explanation:
Proportion of the population that is contaminated = P = (4/17) = 0.235
We now need to find the probability that not more than 1 of the 4 bottles tested is contaminated. This is a binomial distribution problem.
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = number of bottles to be tested = 4
x = Number of successes required = 0, 1
p = probability of success = probability that a bottle is contaminated = 0.235
q = probability of failure = probability that a bottle is NOT contaminated = 1 - 0.235 = 0.765
P(X ≤ 1) = P(X=0) + P(X=1) = 0.34248830063 + 0.4208352975 = 0.7633235981 = 0.7633 to 4 d.p

Answer:
We have the same homework!!!!
hours that passed= 10
Step-by-step explanation:
(1st step)We start with the expression:
(1st)82-0.4x=78
"STARTED at 82 degrees" 82
"Cooling DOWN 0.4 degrees" -0.4
"EACH hour" x
"NOW 78 degrees" =78
(2nd step) We want to get the variable x alone, so we have to do the opposite sign they have, to cancel the number out for it to be 0.
(1st) 82 -0.4x =78
(2nd) -82 ÷-0.4 =78
(3rd)Now, you work out the problem (transfer the numbers from the left to the right). First, you have to do the subtraction sign, not sure why.
(1st) 82 -0.4x =78
(2nd) -82 ÷-0.4 =78
(3rd) 78 -82= -4
-4÷-0.4= 10
X= 10
there you have it!
To make sure this is correct, you do the following.
82 -0.4 x 10
Solve using PEMDAS
-0.4 x 10 = -4
its time to add 82.
82 - 4 = 78
78 is the exact temperature that was said in the problem
-7/8
Step-by-step explanation:

So, the value of xy/8 is -7/8
