Given,
Solving the above equation,
![x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%5Cpm%5Csqrt%5B%5D%7Bb%5E2-4ac%7D%7D%7B2a%7D)
Here, a=-3, b=3 and c=7
Therefore,
![x=\frac{-3\pm\sqrt[]{9+84}}{-6}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%5Cpm%5Csqrt%5B%5D%7B9%2B84%7D%7D%7B-6%7D)
![x=\frac{-3+\sqrt[]{93}}{-6}\text{ or }x=\frac{-3-\sqrt[]{93}}{-6}\text{ }](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%2B%5Csqrt%5B%5D%7B93%7D%7D%7B-6%7D%5Ctext%7B%20or%20%7Dx%3D%5Cfrac%7B-3-%5Csqrt%5B%5D%7B93%7D%7D%7B-6%7D%5Ctext%7B%20%7D)
Therefore,
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:
Length of AB=Length of A'B' because they are corresponding sides.
you should definetely mark me brainliest ;)
I’m pretty sure that the one you marked is correct
I think the correct answer among the choices listed above is option C. The only true statement is that t<span>he domain of the logarithmic function f(x) = log5x is all positive real numbers. Hope this answers the question. Have a nice day.</span>
