Answer: 20 names from each grade
Step-by-step explanation:
The two answers it comes down to are between every student from all of her classes and 20 students from each grade, however since the poll wants to determine how many people across the entire student body would attend, pulling from just Miranda's classes would add a grade level bias to the dance and would not be entirely random. 20 students from each grade is completely unbiased and properly represents the entire student body.
The speed of Maglev train is 267 miles per hour.
Step-by-step explanation:
Given,
Speed of Maglev train = 430 kilometers per hour
We know that;
1 kilometer = 0.62 miles
Therefore,
430 kilometers = 0.62*430
430 kilometers = 266.6 miles
Rounding off to nearest whole number
430 kilometers = 267 miles
The speed of Maglev train is 267 miles per hour.

Answer:
The cost before tax with tip is $15.21.
Step-by-step explanation:
To calculate percentage, take the percent (17%) and take its decimal form. This means 17% is 0.17 (like 50% would be 0.5). multiply the number you want the percentage of by the decimal form. 13*0.17=2.21. Add this to the cost before tax and before tip. 13.00+2.21=15.21. The cost before tax with tip is $15.21.
