5(3x-1)
(x-3)(x-2)
I don't know if you want working out or an explanation? Or if it's too late, sorry.
Answer:
Step-by-step explanation:
The original price was 43 dollars
The new price is 55/100 * 43
The new price is 2365/100
The new price is 23.65 dollars
2365 came from multiplying 43 * 55 which is 2365
Answer:
a)
b)
c) n=62
d) n=138
Step-by-step explanation:
Note: "Each chip contains n transistors"
a) A chip needs all n transistor working to function correctly. If p is the probability that a transistor is working ok, then:
b) The memory module works with when even one of the chips is defective. It means it works either if 8 chips or 9 chips are ok. The probability of the chips failing is independent of each other.
We can calculate this as a binomial distribution problem, with n=9 and k≥8:
c)
This equation was solved graphically and the result is that the maximum number of chips to have a reliability of the memory module equal or bigger than 0.9 is 62 transistors per chip. See picture attached.
d) If the memoty module tolerates 2 defective chips:
We again calculate numerically and graphically and determine that the maximum number of transistor per chip in this conditions is n=138. See graph attached.
Answer: The answer is B (or the second one)
Answer:
Step-by-step explanation:
(7-98)(7+98)
= 7^2 - 98^2
= 49 - 9604
= -9555
