The making of the candles is an illustration of unit rates
The minimum amount of wax the store owner needs to make 60 candles is 180 grams
<h3>How to determine the amount of wax needed</h3>
The number of candles is given as:
n = 60
The amount of wax needed for a candle is not given.
So, we make use of an assumed value.
Assume the minimum amount of wax needed to make a candle is 3 grams.
Then, the amount needed for 60 would be:
Amount = 60 * 3
This gives
Amount = 180
Hence, the minimum amount of wax the store owner needs to make 60 candles is 180 grams (using the assumed value)

Answer:
The value is c = 21.1445.
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.
The weight distribution of parcels sent in a certain manner is normal with mean value 12lb and standard deviation 3.5 lb.
This means that
What value of c is such that 99% of all parcels are at least 1 lb under the surcharge weight?
This 1 added to the value of X for the 99th percentile, which is X when Z has a p-value of 0.99, so X when Z = 2.327.
1 + 20.1445 = 21.1445
The value is c = 21.1445.
The % margin of error means that the real value is in the range between the mean less the margin error and the mean plus the margin error. This is [ mean - % of error, mean + % of error]. Then, in this case the error of +/- 2% means that the expected population proportion that wants flexible working hours is between 60% - 2% and 60% + 2%, which is between 58% and 62%.
