Answer:
Step-by-step explanation:
a. Yes, the following statement is true. The police officer is gathering data by writing down all the speeding tickets and seperating them into two categories, red and non-red cars. He can later analyze this data and compare them to determine whether or not his hypothesis is true.
b. The color of the car is the only variable that would not be a confounding variable in this scenario. This would instead be the independent variable and does not in any way affect the dependent variable which would be the number of speeding tickets received.
An irrational number is a number that can't be written as a simple fraction such as pi because you can't turn pi into a fraction.
The sum is 15.
Divide 15 by three to get Jane's age= 5
The remainder, which is J * 2, or ten, is Randy's age.
Randy is ten.
