Hello!
To answer these, you can use prime factorization! Here is the first one:
1) 16x² and 8
Well we know the GCF will not have any "x" since only one of the numbers do. So, here is the prime factorization for each, excluding the "x", and I have also bolded the common numbers between the two:
16 8
2 · 8 2 · 4
2 · 4 2 · 2
2 · 2
Finally, multiply the common numbers (only once for each common number): 2 x 2 x 2= 8 is your GCF!!!
Hope this helps! :)

Answer:
The probability that she will have breast cancer is 0.2375.
Step-by-step explanation:
P(Positive if no Cancer) = 86.6/1000 = 0.0866
P(Positive if Cancer) = 1 − 1.1/1000 = 0.9989, and
P(Cancer) = 1/38 = 0.0263
If a woman between the ages of 50 and 59 has a positive mammogram, the probability that she will have breast cancer will be calculated by using the Bayes rule.
Bayes’s theorem describes the probability of an event.
P(Cancer if Positive) = 
= 
= 0.2375
