Answer:
0.0776
Step-by-step explanation:
In order to solve this problema, Baye´s rule is used. Ii is expressed as follows:
P(A if B)=(P(B if A)*P(A))/(P(B))
Let A be women who have cancer and let B be women who have positive mammographies
So, P(B if A) would be women with breast cancer get positive mammographies
P(B if A) = 0.8
P(A) would be women with breast cancer
P(A) = 0.01
P(B) would be the women with positive mammographies. We don´t know it.
In order to find it we use law of total probability
P(B) = P(positive mammographies and cancer) + P(positive mammographies without cancer)
P(B) = 0.8*.01+0.096*0.99
P(B) = 0.103
With P(B) calculated we can complete the equation:
P(A if B)=(0.8*0.01)/0.103=0.0776
Probability is 0.0776
Answer:
they would get somewhere from 80% to 85%
Step-by-step explanation:
Answer:
1080°
Step-by-step explanation:
(n - 2) x 180
n = number of sides = 8
(8 - 2) × 180 = 1080°
now, the (x-3) is there 5 times, namely (x-3)(x-3)(x-3) and (x-3)(x-3), that simply means, the root of 3 has a multiplicity of 5, is all
to get the y-intercepts, simple, when the graph touches the y-axis, "x" is zero, thus
