Answer:
x=7 and y= 1/3
Step-by-step explanation:
we have -5x - 15 = -30 <=> x + 3 = 10
x= 7
if x=7
so 2×7 - 6y = 12 <=> 14 - 12 = 6×y
2 = 6y
y= 2/6 = 1/3
C. 60%
The probability that a person surveyed is 40 or older and gets the news by reading the paper is 60%.
Step-by-step explanation:
In our case, we have to find the probability of a person getting their news by reading the paper. But we are given with a condition that the person must be 40 or older.
The survey is conducted among 80 people.
Number of people aged 40 or older = 40
No of people aged 40 or older and read paper = 24
Probability formula is the ratio of number of favorable outcomes to the total number of possible outcomes.
Probability of a person aged 40 or older reads a paper =
(No. of People aged 40 or older and read paper)/(No. of people aged 40 or older)
= 24/40
= 0.6
= 60%
