p,q,r are statements
Step-by-step explanation:
This is the concept of combination. The number of letter-sequence that are possible to be formed from the letters q,u,a,k,e,s will be evaluated as follows:
Total number of letters is 6
Maximum number of letters in a word is 4
thus the number of four letter sequence that can be formed will be:
6C4
=15
The reason why we are using combination is because no letter can be used more than once in each sequence.
Answer: -3
Step-by-step explanation:
Find slope using the slope formula y2-y1/x2-x1. I'll use the points (-3,5) and (-2,2) so 5-2/-3-(-2) = 3/-1 = -3
5a+(a+60)°+(2a+140)° = 360°
5a+a +60+ 2a+ 140 = 360
8a= 360-60-140
8a = 160 ( divide by a 8 on both sides)
a = 20°
