Answer:
0.0051 = 0.51% probability that the thickness is less than 3.0 mm
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 4.8 millimeters (mm) and a standard deviation of 0.7 mm.
This means that
(a) Probability that the the thickness is less than 3.0 mm
pvalue of Z when X = 3. So
has a pvalue of 0.0051
0.0051 = 0.51% probability that the thickness is less than 3.0 mm
Answer:
0.942
Step-by-step explanation:
Multiply the normal way as if there were no decimals, then move the decimal 3 times to the left.
Answer:
1/5, 4/5, 5/5
Step-by-step explanation:
1/5 is 20%
4/5 is 80%
5/5 is 100%
Decimal form 0.08 and precent form 8% you can also simply it so it can also be 4/50 and 2/25
0.08, 8%, 4/25, 2/25 are all equivalent to 8/100
1 km = 1000 m and 1m = 100cm
1 km is the same as 1000 m = 1000 x 100 = 100000 cm
There are 862 kilometres so there is 862 x 100000 = 86200000 cm in 862 km.
