Answer:
Intersect: (4 4/7 , 2 6/7)
Step-by-step explanation:
A: slope (m)= (-10-8) / (-9 - 10) = 18/19
Equation: y-8 = 18/19 * (x-10)
18x -19y = 28 (1)
B: slope (m) = (12 - -2) / (0 - 7) = -2
equation: y-12 = -2 *(x - 0)
2x + y = 12
38x + 19y = 228 (2)
(2) + (1): 56x = 256 x = 4 4/7
y = 12 - 2x = 12 - 64/7 = 2 6/7
Answer:
The percentage of people having cholera is 89.19%.
Step-by-step explanation:
According to the Bayes' theorem the total probability of <em>A</em> is:

Let <em>X</em> = a person has chorea and <em>Y</em> = the test is positive.
Given:

The value of
is:

Compute the value of P (X) as follows:

The percentage of people suffering form cholera is, 0.8919 × 100 = 89.19%.
Thus, the percentage of people having cholera is 89.19%.
When the ball reaches the ground is equal to one of the zeros, or x-intercepts. In order to find the zeros of a function, you need to factor the equation.
y=16x^2+64x
y=-16x(x-4)
The zeros are x=0 and x=4
Therefore the answer is D, after 4 seconds.
Hope this helps!
y = 115
x = 78
The angles in each line have to add up to 180. In this case, it doesn't show the other side of the angle, but you could probably think of it.
