Answer:
(x + 3)
Step-by-step explanation:
Using the zero product property
x-a = 0 x-b = 0 where a and b are the zeros
(x-a)(x-b) =0
(x- -3)(x -8) =0
(x+3) (x-8) =0
Multiply 9 and 5 then multiply by .5 giving you 22.5 so I’d say that’s your best option
Answer:
30 and 3.4641
Step-by-step explanation:
The mean of a binomial distribution is:
μ = np
And the standard deviation of a binomial distribution is:
σ = √(npq)
Here, n = 50, p = 0.60, and q = 0.40.
μ = np = 50 × 0.60 = 30
σ = √(npq) = √(50 × 0.60 × 0.40) = 3.4641
Answer:
6 1/12
Step-by-step explanation:
3 2/3= 3 8/12, 1 3/4= 1 9/12, 2/3= 8/12 || add (3 8/12+ 1 9/12+ 8/12= 4 25/12= 6 1/12)
Answer:
name them
A=(-2,5)
B=(-2,1)
C=(1,1)
sides:
AB=c=4
AC=b=√(3²+4²)=5
BC=a=3
then we do this
2p=a+b+c
2p=3+4+5=12
p=6
then we calculate the area:
√(p(p-a)(p-b)(p-c))
Area=√6(6-3)(6-4)(6-5)
Area=√(6×3×2×1)
Area=√36=6
