If the sample is truly random, every member of the population should have an equal chance to be selected. Because of this, Paula and Peter's probability of being chosen will be equal: 1/9800
174/3=58 miles in one hour 7*58=406 miles
or you and do 7/3*174=406
Answer:
$1800
Step-by-step explanation:
You would use proportions. 11.5/100 (11.5%) multiplied by 207/x.
Cross multiply 100 and 207, then divide that answer by 11.5. You should get 1,800 as your answer.
Therefore, the dollar amount of shoes that Maria sold is $1800.
3 because 21/3 is 7. 24/3 is 8. And 27/3 is 9.
5ax+2a=9a
5ax+2a-2a=9a-2a
5ax =7a
5ax/5a =7a/5a
x=7/5
