Answer: 53.65
Step-by-step explanation
First you need to write out the equation
37 x .45 = 16.65
Then you take 16.65 which is the percent mark up and add it to the original price of $37 and you get your answer of 53.65
The answer would be the top left one because when dividing, you would subtract 8 from 13. I'm pretty sure not 100% though. Sorry.
Answer:
1) C
2) C
3) A
Step-by-step explanation:
1) The right answer is C.
Each volunteer is a pair, consisting of the test of each chair. The difference can be compared for each individual and treated as a paired t-test.
2) The right answer is C.
There is no paired relation between the houses of each sample. There are two independent samples with the same sample size.
3) The right answer is A.
The hours are selected at random, so there is no relation between the hours picked for each worker. There are two indpendent samples with the same sample size.
Answer:
Domain: 1 ≤ x ≤ 4
Range : 1 ≤ f(x) ≤ 4
Step-by-step explanation:
The domain of a function f(x) is the limit within which the values of x varies.
Here, in the graph, it shows that the maximum value of x is 4 and the minimum value of x is 1.
Therefore, the domain of the function is 1 ≤ x ≤ 4
Again the range of a function f(x) is the limit within which the values of f(x) vary.
Here, the graph shows that the maximum value of f(x) is 4 and the minimum value of f(x) is 1.
Therefore, the range of the function f(x) is 1 ≤ f(x) ≤ 4. (Answer)
