Step-by-step explanation:
x is the independent variable
y is the dependent variable
Answer:
2/7 and 1/2
The common denominator = 7× 2
= 14
Step-by-step explanation:
We're told that
a. We want to find 
. By definition of conditional probability,
By the law of total probability,
Then
(the first equality is Bayes' theorem)
b. We want to find 
.
since 
.
Well basically the formula for the area of the circle is pi r squared. First you square 3 which is 9 and then you times it by 3.14 which gives you 28.26.Hope this helps!

Answer:
3. m∠A < 80°
Step-by-step explanation:
The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.
If we assume that angle measures cannot be zero, then we must have ...
m∠A +m∠N = 80°
m∠A = 80° -m∠N
Since m∠N > 0, the measure of angle A must be less than 80°.
This conclusion matches choice 3.
