When rounding 243.875: to the nearest tenth, it becomes 243.9; to the nearest hundredth, it is 243.88; to the nearest ten, it rounds down to 240; and to the nearest hundred, it rounds down to 200. The general rule in rounding states that if the decimal is less than 5, the number remains the same; if it is 5 or more, you round up.
Question:
Let p: x = 4 Let q: y = −2 Which represents "If x = 4, then y = −2”? p ∨ q p ∧ q p → q p ↔ q
Answer:
The correct option is c: p → q
Explanation:
Option a: p ∨ q
p ∨ q indicates that either p is true, or q is true, or both hold true.
Therefore, Option a is not the right answer.
Option b: p ∧ q
p ∧ q signifies that both p and q are true.
Thus, Option b is not the correct choice.
Option c: p → q
p → q means if p is indeed true, then q must also be true.
So, Option c is the right choice.
Option d: p ↔ q
p ↔ q implies that if p holds true, then q is true, and vice versa.
Thus, Option d is not the correct option
.
Therefore, p → q is the accurate option.
Response: The accurate statements include:-
There are nearly equal quantities of points located above and below the x-axis.
The points are distributed haphazardly without a distinct pattern.
The total number of points matches that of the scatter plot.
Explanation:
- A residual plot illustrates residuals on the vertical axis against the independent variable on the horizontal axis.
Consequently, the count of points is on par with the scatter plot, and roughly the same amount of points exist above and below the x-axis.
Given the random distribution of the points throughout the plot, it signifies there is no correlation, therefore, the points are scattered randomly without a clear arrangement.
Answer:
The inequality can be expressed as:
49.3 + 4.8r < 74.5
The solution set indicates that r < 5.25
Step-by-step explanation:
Initially, we must determine the median from the provided dataset. To achieve this, we need to sort the values:
12, 15, 18, 20, 23, 23, 28
Thus, the median appears to be 20
To ensure the median remains unchanged, the eighth hour would need to have 20 visitors, allowing the revised dataset to be:
12, 15, 18, 20, 20, 23, 23, 28
I hope this clarifies things!
