The equation of line a is obtained by multiplying the equation of line b by 4. i.e. there are linearly dependent and hence there are infinitely many solutions to the set of equations.
C. 5/2.
You can get the scale factor by putting the measurements of similar sides on a fraction,
In this case 20/8 =5/2, 10/4 = 5/2
The combination shows that the different groups of three that can be chosen for a newspaper photo is 10.
<h3>How to calculate the value?</h3>
From the information, Joyce, Karen and Paula are starters on their school basketball team.
The information is to illustrate the different groups of three that can be chosen for a newspaper photo.
This will be:
= 5!/3!(5 - 3)!
= 5!/3!2!
= (5 × 4 × 3 × 2 × 1)/(3 × 2 × 2)
= 20/2
= 10
There will be 10 groups.

Answer: a) 0.0792 b) 0.264
Step-by-step explanation:
Let Event D = Families own a dog .
Event C = families own a cat .
Given : Probability that families own a dog : P(D)=0.36
Probability that families own a dog also own a cat : P(C|D)=0.22
Probability that families own a cat : P(C)= 0.30
a) Formula to find conditional probability :
(1)
Similarly ,
Hence, the probability that a randomly selected family owns both a dog and a cat : 0.0792
b) Again, using (2)
Hence, the conditional probability that a randomly selected family owns a dog given that it owns a cat = 0.264
