Step-by-step explanation:
We have given that,
The inner radius of a bicycle wheel is 12 inches.
It is required to find the expression to find the inside circumference of this wheel.
The outer surface of the wheel is equal to its circumference. It is given by :

r is radius of wheel

This is the required explanation.
Answer:
When a point is reflected across the y-axis, the y-coordinate(s) remain the same. But the x-coordinate(s) is transformed into opposite signs.
Answer:
-5z - 2
Step-by-step explanation:
x - yz when x = -2 and y = 5
-2 - 5z
Since we don't have any like terms and an equal sign, we can't simplify any further.
Best of Luck!

Step-by-step explanation:
1) The restaurants were measured for each restaurant to give ratings as observations is being carried out on restaurants
2) The percentage of customers was measured to determine ratings. The food and decor can't be measured. Seating capacity is not a measurement variable.
3) The date of measurement is not mentioned
4) The measurement would have to be taken at restaurant obviously.
5) The measurments were taken to determine the ratings and decide the best restaurant
6) Since percentage of customers was measured, the customers had to be surveyed.
7) There are no categorical variables. All variables were measured on the scale of 30
8) Quantitative variable under investigation is number of customers who returned.
9) This is a survey not a design experiment. In design experiment, somethig is put on a test.
10) This is a cross-sectional data. nothing is being measurd over a period of time
11) There are no specific ocncerns since no data is mentioned in the question.
