Answer: 60 students
Step-by-step explanation:
So, in the first situation 430 students were surveyed and 258 said that their favourite pet was a dog. The second situation is 100 students and x said that their favourite pet was a dog. We are solving x.
430=258
100= x
Cross multiply
So that is
430 x X= 100x258
430x=25800
Divide both sides by 430
Answer: 60 students
X=1
Y=6
X=3
Y=18
X=5
Y=30
X=7
Y=42
X=9
Y=54
Mode are repeating numbers in a sequence therefore 23 is your mode
Set up an equation to solve.
