The probability is 0.0334.
We will first find the probability that none of the 30 people sampled are infected. Since the probability of one person being infected is 0.00114, the probability that someone is not infected is 1-0.00114 = 0.99886. The probability that none of the 30 people are infected would be (0.99886)^30 = 0.966359. We subtract this from one to find the probability that at least one person is infected:
1 - 0.966359 = 0.0334.
Answer:
x^2+16x+64
Step-by-step explanation:
(x+8)(x+8)
x(x+8)+8(x+8)
x^2+8x+8x+64
=x^2+16x+64
It might just be old pal :)
Hello there! When it comes to scientific notation, a number greater than or equal to 1, but less than 10 is multiplied by a power of 10. For example: 3.45 * 10^6. 0.95 is less than 1, so the first one is not in scientific notation. All of the others fit, because the numbers are greater than 1, but less than 10, and are mutliplied by a power of 10. The answer is A.
−3b+2.5=4
Subtract 2.5 from both sides.
−3b+2.5−2.5=4−2.5
−3b=1.5
Divide both sides by -3.
−3b/−3 = 1.5/−3
b=−0.5
