Answer:
0.049
4.9 % of probability
Step-by-step explanation:
The probability of having the disease is equal to 7%
The probability of testing positive, having the disease is equal to 70%
We are looking for the probability of testing positive.
For that, we need to multiply the probabilities to find the result
P = (0.07)*(0.7)
P = 0.049
P = 4.9%
Answer:
D. K+2K=51
Step-by-step explanation:
Since Lauren is 2 times Kristy's age, Lauren's age=2K
so, if the sum of the two is 51, then 2K+K=51
If you want to solve it, 2K+K=3K=51
51/3=K
17=K
34=L
This is how to find a slope:
y2 - y1 over like a fraction on
x2 - x1
So we would do
-2 - 1 over
0 - 2
and you would get the slope of
-3/-2
Since there can't be two negatives it turns into a positive fraction like this
3/2 = Slope
If you want to graph this it would rise 3 points in the y axis and run 2 points in the x axis
