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.
The translation rule can be expressed as T -3,1(x,y). The translation can also be indicated as (x,y)➡️(x-3,y+1).
Answer:
The total probability exceeds 100%, indicating a problem with the findings; moreover, the distribution shows excessive uniformity which disqualifies it as a normal distribution.
Detailed explanation:
The sum of probabilities should be exactly 100%. When you add the probabilities of this distribution:
22+24+21+26+28 = 46+21+26+28 = 67+26+28 = 93+28 = 121
This exceeds 100%, highlighting a significant error in the results.
A typical normal distribution possesses a bell curve. If we plot the probabilities for this distribution, we'd see bars at 22, 24, 21, 26, and 28.
The bars would fail to form a bell-shaped curve, confirming that this is not a normal distribution.
