Answer:
0.3085 = 30.85% probability that a randomly selected pill contains at least 500 mg of minerals
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 490 mg and variance of 400.
This means that 
What is the probability that a randomly selected pill contains at least 500 mg of minerals?
This is 1 subtracted by the p-value of Z when X = 500. So



has a p-value of 0.6915.
1 - 0.6915 = 0.3085
0.3085 = 30.85% probability that a randomly selected pill contains at least 500 mg of minerals

Answer:
Alright well the Answer to this question is
9 Hope this helps :)
Step 1: Convert to mixed number 1 7/9 into an improper fraction first by multiplying the denominator, by the whole number
Step 2: Then add the numerator, to get the new numerator. Place the New numerator over the old denominator
16 divided by 16 and 9
To divide by fraction, multiply by it's reciprocal 16(9/16)
Cancel the common factor of 16, then simplify 1/1 9/1 which gives u
