It would be helpful if you show me the figure. Thanks :) !!
Answer:
66.48% of full-term babies are between 19 and 21 inches long at birth
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 length of 20.5 inches and a standard deviation of 0.90 inches.
This means that 
What percentage of full-term babies are between 19 and 21 inches long at birth?
The proportion is the p-value of Z when X = 21 subtracted by the p-value of Z when X = 19. Then
X = 21
has a p-value of 0.7123
X = 19
has a p-value of 0.0475
0.7123 - 0.0475 = 0.6648
0.6648*100% = 66.48%
66.48% of full-term babies are between 19 and 21 inches long at birth
The elevation represents a distance from the sea level greater than 5 feet,
because the original description specifies a distance greater than 5 feet
below sea level.
Reasons:
The elevation given as a distance is the height or distance above sea level.
In the above description, elevation is a vector, given that it has both
magnitude (distance) and direction (above sea level).
Distance is a scalar quantity, that has only a magnitude that specifies the
space covered during motion.
An elevation of less than -5 feet indicates that distance of the location
above sea level is less than -5 feet, which is the same as; the distance of
the location below sea level is greater than 5 feet.
- Less than -5 feet above sea level = Greater than 5 feet below sea level
Therefore;
- An elevation of less than -5 feet represents a distance from (below) sea level greater than 5 feet

You are correct, C) 4x = 12.
So, if 4 people are eating 12 pieces of pizza, simply divide 12 by 4 and there's your answer!
12 / 4 = 3 Each person gets 3 slices of pizza.
