Area = S^2
S(S-3) =70
S^2 -3S = 70
S^2 - 3s-70 = 0
(s-10) (s+7) = 0
s = 10, s=-7
S=10
original dimension was 10cm x 10cm
Answer:
Step-by-step explanation:
a)
p(d) - probability of a rivet being defective
p(r) - probability of seam needing to be reworked
The probability of the seem needing to be reworked is equal to the probability that ANY of 24 rivets is defective
Thus the probability that none of the 25 rivets is defective is 1-p(r)
p(r) = 16%, thus 1-p(r) = 84%
1-p(r) = (1-p(d))^24
0.84 = (1-p(d))^24
0.84^(1/24) = 1-p(d)
==> 1-p(d) = 0.9927615998
==> p(d) = 1-0.9927
==> p(d) = 0.0073
b) given p(r) = 8%, thus 1-p(r) = 92%
1-p(r) = (1-p(d))^24
0.92 = (1-p(d))^24
0.92^(1/24) = 1-p(d)
==> 1-p(d) = 0.99653179446
==> p(d) = 1-0.9965
==> p(d) = 0.0035
Answer:
= 2√6
Step-by-step explanation:
a² + b² = c²
1 + b² = 25
b² = 24
b = ±√24
b = ±2√6
We can forget about the minus answer because you cannot have a negative length. That does not make sense.
Please mark me brainliest.
Answer: %512 increase.
Step-by-step explanation:
Soooo if you had $1 and the prize was $512, then youd be making $512 (because you lost/invested the $1), It would be a 512% increase. Now, if it was $51,200 youd win, then yes it would be a 51,200%, but its only $512.
