Answer Step-by-step explanation:
Given statement if a-b is even and b-c is even then a-c is even .
Let p: a-b and b-c are even
q: a-c is even.
Converse: If a-c is even then a-b and b-c are both even.
Inverse:If a-b and b-c are not both even then a-c is not even.
If a= Even number
b= Even number
c=Even number
If a-c is even then a-b and b-c are both even..Hence, the converse statement is true.
If a=Odd number
b=Odd number
c= Odd number
If a-c is even then a-b and b-c are both even number .Hence, the converse statement is true.
If a=Even number
b= Even number
c= Odd number
a-b and b-c are both odd not even number but a-c is even number
a=8,b=6 c=3
a-b=8-6=2
b-c=6-3=3
a-c=8-3=5
If a-c is odd then a-b even but b-c is odd .Hence , the converse statement is false.But the inverse statement is true.
If a= Odd number
b=Even number
c= Even number
If a-b is odd and b-c is even then a-c is odd not even . Hence, the inverse statement is true.
If a= Odd number
b=Eve number
c=Odd number
a=9,b=6,c=5
a-b=9-6=3
b-c=6-5=1
a-c=9-5=4
Here, a-b and b-c are not both even but a-c is even .Hence, the inverse statement is false.
C sometimes, It seems to be completely arbitrary when one must subtract the z-score table value from 1. ... So that's great if you want the left tail of a distribution, but if you want a right tail then you need to calculate the left tail and subtract it from 1 (which is the area of the entire standard normal curve).
Answer:
The answer to your question is 31.4°
Step-by-step explanation:
Data
SR = 54 cm
SQ = 99 cm
RQ = 141 cm
∠QRS = ?
Process
1.- Use the law of cosines to find ∠QRS
cos QRS = (SQ² - RS² - RQ²) / -2(SR)(RQ)
-Substitution
cos QRS = (99² - 54² - 141²) / -2(54)(141)
-Simplification
cos QRS = (9801 - 2916 - 19881) / -15228
cos QRS = -12996 / -15228
cos QRS = 0.85343
2.- Find QRS
∠QRS = 31.4°
