1. you can use fractions, reduce the number, or compare them and if they are the same
then they are classified as proportional.
2. you can use a graph by graphing two sets of numbers, if it’s proportional it will form a straight line that goes through the origin.
Answer:
Yes
Step-by-step explanation:
Permutation :
nPr = n! ÷ (n - r)!
nCr = n! ÷ (n-r)!r!
11 objects taken 3 at a time :
11P3 = 11! ÷ (11 - 3)!
11P3 = 11! / 8!
11P3 = (11 * 10 * 9 )
11P3 = 990
Dividing by 3!
3! = 3*2*1 = 6
= 990 / 6
= 165
For combination :
11C3 = 11! ÷ 8!3!
11C3 = (11 * 10 * 9) / (3 * 2 * 1)
11C3 = 990 / 6
11C3
Answer: 2x(x+2)−(x+2)
Step-by-step explanation:
Factor out common terms in the first two terms, then in the last two terms.
2x(x+2)−(x+2)
Factor out the common term x+2.
(x+2)(2x−1)
Answer:
No. 1 is inductive, cos the evidence is based on proberbility as not all pennies are silver color, since thier color could change over time (fade)
while
No 2 is deductive since all even numners are divisible by 2, there is a full assurance of the outcome.
A. it has a volume of 1 cubic unit
