Hello there i hope you are having a great day :) Your question: Suppose 21% of people own a dog. If you pick two people at random, then what is the probability that they both own a dog?
1) 21% own a dog so you would do 21/100 = 0.21 this would equal the first person now the second person you would do 21/100 = 0.21
2) now you would multiply it so 0.21 x 0.21 = 0.0441 the that would be your answer.
Hopefully that helps you ❤
Answer:
31x+74y=p
31(9)+74(4)=p
279+256=525
Step-by-step explanation:
Define x:
Let the sum be x
Construct the equation:
<span>The sum of 3 times a number and 5 is 2 times the number plus 15.
</span>→ 3x + 5 = 2x + 15
Solve x:
3x + 5 = 2x + 15 | Equation
x + 5 = 15 | Take away 2x from both sides
x = 10 | Take away 5 from both sides
Answer: The number is 10.
