Answer:
12.5≤x<13.5
Step-by-step explanation:
below 12.5, it would round down to 12
13.5 and above, it would round up to 14
Answer:
E
Step-by-step explanation:
7+8+4=19
4/6 + 3/6 + 1/6 = 1 2/6
19 + 1 1/3
20 1/3
9^2 (write it like a exponent)
Answer:
0.6827
Step-by-step explanation:
Given that :
Mean, μ = 3
Standard deviation, σ = 0.1
To produce an acceptable cork. :
P(2.9 < X < 3.1)
Recall :
Z = (x - μ) / σ
P(2.9 < X < 3.1) = P[((2.9 - 3) / 0.1) < Z < ((3.1 - 3) / 0.1)]
P(2.9 < X < 3.1) = P(-1 < Z < 1)
Using a normal distribution calculator, we obtain the probability to the right of the distribution :
P(2.9 < X < 3.1) = P(1 < Z < - 1) = 0.8413 - 0.1587 = 0.6827
Hence, the probability that the first machine produces an acceptable cork is 0.6827
