Answer:
Therefore the correct answer is A.) 84.88%
Step-by-step explanation:
i) λ = 2
ii) λ for three units = 2
3 = 6
iii) P(x ≥ 4) = 1 - P(x < 4) = 1 - {P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) }
= 1 - {
}
= 1 - (0.0025 + 0.0149 + 0.0446 + 0.0892)
= 0.8488
Therefore the correct answer is A.) 84.88%
Wouldn't it be 72 72/24=3 72/18=4 72/12=6 72/6=12
Answer:
C
Step-by-step explanation:
The zero property of multiplication is when you multiply a number by zero, it will always be zero. -1/6 x 0 = 0. Then add 8. 0+8=8
9(10)=90
8(9)=72
7(8)=56
6(7)=42
5(6)=30
4(5)=20
3(4)=12
3=12
Yes, it is proportional. Every book is $4. 3 x 4 is 12, 7 x 4 is 28.
