Answer: 1. a
2. -75
Step-by-step explanation:
Answer:
It's y = (5)(0.2)^x
_____________
Step-by-step explanation:
Exponential functions have a standard form of ab^x
Where a is the starting value, and b is the exponential growth or decay.
Because the numbers are getting smaller and smaller, it is a decay so b must be less than one.
We can eliminate the first choice because when x is 1, y is 1. If this where the equation we would get (5) (1/2) ^ 1 = 5 × 1/2 = 2.5 ≠ 1.
So the answer must be the second choice.
Answer:
The answer is 5.5, 6.0 and 8.0
Answer:
1) the number of hours of TV watched
2) quantitative
3) Mean or Median
Completed details of Question
Additional details to the question are as below
1) Identify the variable measured on each student.
2) Is the variable categorical or quantitative?
3) Identify two statistics that the student could use to summarize the variable.
a) Mean or Median
b) Mean or Proportions
c) Mean or Mode
d) Median or Mode.
Explanation to the answer:
1) The variable measured on each student is the number of hours of TV watched
2) The variable is the amount of time, therefore it is quantitative.
3) Quantitative data can be used compare the exact size and extent of difference in two quantities. Therefore, the two statistics that the student could use to summarize the variables would be Mean or Median. Mean will be the average time and Median will be the middle when the amount of time is ordered from least to greatest.
