Answer:
10x^2 (x+2) (x+6)
Step-by-step explanation:
assuming you meant 120 not 1120
10x^4+ 80x^3 + 120x^2
factor out 10 x^2
10x^2 (x^2 +8x+12)
what numbers multiply together to get 12 and add together to get 8
2*6 = 12 2+6 = 8
10x^2 (x+2) (x+6)
B and D are the same answer?????
In a histogram, the highest bar is the mode, which means the number the bar represents appears the most.
The answer would be D. Three, because it appears most often.
1. a b c
2. a b c
3. a b c
4. a b c
5. a b c
then she eliminated 1 choice in 1 and 2, say as follows
1. b c
2. a b
3. a b c
4. a b c
5. a b c
Probability of answering correctly the first 2, and at least 2 or the remaining 3 is
P(answering 1,2 and exactly 2 of 3.4.or 5.)+P(answering 1,2 and also 3,4,5 )
P(answering 1,2 and exactly 2 of 3.4.or 5.)=
P(1,2,3,4 correct, 5 wrong)+P(1,2,3,5 correct, 4 wrong)+P(1,2,4,5 correct, 3 wrong)
also P(1,2,3,4 c, 5w)=P(1,2,3,5 c 4w)=P(1,2,4,5 c 3w )
so
P(answering 1,2 and exactly 2 of 3.4.or 5.)=3*P(1,2,3,4)=3*1/2*1/2*1/3*1/3*2/3=1/4*2/9=2/36=1/18
note: P(1 correct)=1/2
P(2 correct)=1/2
P(3 correct)=1/3
P(4 correct)=1/3
P(5 wrong) = 2/3
P(answering 1,2 and also 3,4,5 )=1/2*1/2*1/3*1/3*1/3=1/108
Ans: P= 1/18+1/108=(6+1)/108=7/108
Answer:
(9,6)
Step-by-step explanation:
(6,9)
Because the scale factor is 3 so u r suppose to multiply by 3
