Answer:
0.5 ; 0.475 ; 0.689 ; 0.4013
Step-by-step explanation:
Given that:
Rate of production of defective batteries p = 0.05
Number of batteries produced (n) = 10
The expected number of defective batteries = mean = n * p = 10 * 0.05 = 0.5 batteries
Variance of defective batteries :
Var(X) = n * p * q ; q = 1 - p
Hence,
Var(X) = 10 * 0.05 * 0.95 = 0.475
Standard deviation (X) = sqrt(variance) = sqrt(0.475) = 0.689
Probability that atleast 1 battery is defective :
Using the binomial probability function
P(x ≥ 1) = 1 - p(x = 0)
= 1 - q^n
= 1 - 0.95^10
= 1 - 0.59873693923837890625
= 0.40126306076162109375
= 0.4013
Answer: Choice C. (x-7)(x-8)
-------------------------------------------------------
Find two numbers that...
* Multiply to 56 (last term)
* Add to -15 (middle coefficient)
Those two numbers are -7 and -8. So that's why x^2-15x+56 factors to (x-7)(x-8)

Answer:
x^2 = 25 x = 5, -5
2x^2 = 98 x = 7, -7
x^2 + 64 = 0 x = 8i, -8i
9x^2 - 16 = 0 x = 4/3, -4/3
x^2 + 9 = 25 x = 4, -4
(x-2)^2 = 25 x = 7, -3
(x-2)^2 +9 = 25 x = 6, -2
4(x-2)^2 +9 = 25 x = 4, 0
