Answer:
this question makes zero sense please rephrase it
Step-by-step explanation:
B. A function is a relation in which each value of the input variable is paired with exactly one value of the output variable.
C. The vertical line test may be used to determine whether a function is one-to-one.
D. A sequence is a function whose domain is the set of real numbers.
C. FALSE, because the vertical line test may be used to determine whether a relation is the function.
D. FALSE, because the function domain can be any set.
Answer:
(minutes) 20 30 40 50
Distance (y)
(miles) 5 10 15 20
Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and distance traveled by the toy car. (4 points)
[Choose the value of correlation coefficient from 1, 0.8, 0.5, 0.02]
Part B: What is the value of the slope of the graph of distance versus time, and what does the slope represent? (3 points)
Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)
Part A: The correlation coefficient is 1. It means that the values of both x and y has a strong relationship giving them a avalue of 1.
Part B: The value of the slope of the graph is 0.5. the slope of the line represents how steep is the line of your graph
Part C: The data presented is correlation.
Answer: The vertex of the given function is (-4,0).
Step-by-step explanation:
Since, the standard form of an absolute function is,
y = a|x-h| + k
Where (h,k) is the vertex of the function,
Here, the given function is,
y = -|x+4|
⇒ y = (-1)|x-(-4)| + k
By comparing,
We get, a = -1, h = -4 and k= 0
Hence, the vertex of the given function is (-4,0).
Answer: A & D
Step-by-step explanation:
Hot Outside = Buy Ice cream cone
Buy Ice cream cone = Hot outside
A. You buy an ice cream cone if and only if it is hot outside.
This is true because you do buy ice cream when it is hot.
B. You buy an ice cream cone if and only if it is not hot outside.
This is false because you buy ice cream when it is hot.
C. You do not buy an ice cream cone if and only if it is hot outside.
This is false because you buy ice cream when it is hot.
D. You do not buy an ice cream cone if and only if it is not hot outside.
This is true because you only buy ice cream when it is hot, which means you do not buy ice cream when it is not hot.
The largest possible map that can fit on the page is 8 in. by 12 in.
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
We can begin by finding the scale factor by which the map needs to be reduced.
Since the map dimensions are 24 in. by 36 in., and we want to fit it onto a page that is 8 in. by 10 in.
We need to reduce each dimension by the same factor.
Let x be the scale factor:
24/x = 8
36/x = 10
Solving for x, we get:
x = 24/8 = 3
Therefore, we need to reduce the map by a scale factor of 3.
To find the dimensions of the largest possible map that can fit on the page, we divide the original map dimensions by 3:
24/3 = 8
36/3 = 12
Hence, the largest possible map that can fit on the page is 8 in. by 12 in.
