Write a conditional statement. Write the converse, inverse, and contrapositive for your statement and determine the truth value
MrRa [10]

Conditional statement is a statement with a hypotesis and a conclusion:

If \text{ \underline{ hypothesis } } p, then \text{ \underline { conclusion }  } q

or mathematically p\rightarrow q.

Converse statement of p\rightarrow q is statement q\rightarrow p.

If you negate (that means stick a "not" in front of) both the hypothesis and conclusion, you get the inverse:

\neg p\rightarrow \neg q.

Finally, if you negate everything and flip p and q (taking the inverse of the converse) then you get the contrapositive:

\neg q\rightarrow \neg p.

Example:

1. Conditional statement: If I am sleeping, then I have closed eyes. (true)

2. Converse statement: If I have closed eyes, then I'm sleeping. (not necessarily true)

3. Inverse statement: If I'm not sleeping, then I haven't closed eyes. (not necessarily true)

4. Contrapositive statement: If I haven't closed eyes, then I'm not sleeping. (true)

Liono4ka [1.6K]

Answer:

a) 2nd

b) 4.8

c) 4

Step-by-step explanation:

Mode is the highest frequency.

"Away" has highest frequency in the second quarter

Mean = sum/n

Sum of Home goals:

5+4+8+9 = 26

Sum of Away goals:

2+9+7+4 = 22

Total goals = 26+22 = 48

Average = 48/10 = 4.8

No. of home goals - No. of away goals

26 - 22 = 4
