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.

Answer:
7) x= 5, 8) x= 6, 9) x= 7
Step-by-step explanation:
As per the secant theoram, if two secant intersect outside the circle then the product of the exterior secant and total length of each secant are equal.
7) ∴
opening parethesis and distributing 3 with x and 3.
⇒
subtracting 9 on both side.
⇒
cross multiplying
∴ x= 5.
8)
Opening parethesis and distributing 4 with x and 4.
⇒
⇒
subtracting 16 on both side.
⇒
cross multiplying
∴ x= 6.
9)
opening parethesis and distributing 5 with x and 5.
⇒
subtracting 25 on both side.
⇒
cross multiplying
∴ x= 7.
Hi there! We can find the value of x by using this equation.
If you remember, tanx = opposite/adjacent. We focus on the angle x currently.
Now that you might wanna ask if there is a value of x that makes 19/23. The answer is yes but in decimal.
You might wanna put arctan(19/23) in a calculator since it's not really possible to get the square root like value by yourself.
arctan(19/23) is 0.69
Then we round up and get 0.7
Hence, the value of x ≈ 0.7
