A recent study found that 81?% of? breast-cancer cases are detectable by mammogram. Suppose a random sample of 11 women with bre
1 answer:
Answer:
9.847 %
Step-by-step explanation:
Be p1 the probability that the mammogram detect breast cancer in a woman.
p1=81%.
The probability 'P' that independent and consecutive 'n' singular events with p probability occur is:
In this case:
P: Probability that breast cancer be detected on 11 women with breast cancer.

Step-by-step explanation:
since is an equation for a line which intersects with the curve
. The point of intersection, let's say
, should satisfy the two equations. As a result, the value of y in the second equation can be replaced with the value of y in the first equation as the following,
therefore, the latter equation can be rewritten in a quadratic equation form as the following,
= 0
if the line is tangent to the curve, it means that the line touches the curve at one point, therefore the discernment of the second order equation will be equal to zero for the famous quadratic equation solution.
where and
, as a result, the following equations can be deduced,
therefore, dividing both sides by 12
Answer:
All the right triangles will be similar.
Step-by-step explanation:
See the attached diagram.
Let us assume any two right triangles are drawn on the line OP, and AB and A'B' as the hypotenuse on the same line OP.
Since the slope of the line OP is constant and assume that it makes x° with the positive x-axis.
Hence,
⇒
Therefore, the sides of the two right triangles are in the same ratio and hence, Δ ABC and Δ A'B'C' are similar.
Hence, all the right triangles will be similar. (Answer)
