Answer:
a. The Variable is new hybrid small cars miles per galon.
b. The variable is quantiative.
c. All new hybrid small cars
Step-by-step explanation:
a. When we are analizing the variables, we need to see what is the most important factor in this variable. Here we are looking at miles per galon. But the question is specific about new hybrid small cars. So we define the variable as new hybrid small cars miles per galon
b. A qualitative variable is a variable that can't be expressed in numbers. For example when we talk about the colour of a car, that's a qualitative variable. In this problem, we are looking at the consumption of the engine. It's a given number. When we can define measure it with numbers it's a quantitative variable. Therefore this is a quantitative variable
c. The implied population is all the subjects where we are measuring our variable. In here, we are looking at a random sample of all the new hybrid small cars. Since we took a random sample, the idea is that it represents the whole population since we can't measure the consumption on all the new hybrid small cars. Therefore the implied population is all new hybrid small cars
Answer:
Step-by-step explanation:
A
Answer:
this is easy. all you have to do is subtract 102 from 86 (which makes -16) and then divide by -8 (making m equal to 2).
Step-by-step explanation:
102 - 8m = 86
86 - 102 = -16
-16/-8 = 2
Answer:
Let's call the numbers n and n + 2.
(n + 2)² - n²
= n² + 4n + 4 - n²
= 4n - 4
= 4(n - 1)
