If 2 lbs. is 4.20 we can divide that by 2 to figure out what 1 lbs. costs:
4.20 / 2 = 2.10
Now we know one pound of peaches is $2.10 so you multiply that by 5 to see how much 5 lbs. costs:
2.10 (5) = $10.50

Answer: The range of the medians of the numbers left and right of the median of the entire data set.
Answer:
55.563
Step-by-step explanation:
Given the following :
Mean(m) point = 73
Standard deviation( sd) = 10.6
Lower 5% will not get a passing grade (those below the 5% percentile)
For a normal distribution:
The z-score is given by:
z = (X - mean) / standard deviation
5% of the class = 5/100 = 0.05
From the z - table : 0.05 falls into - 1.645 which is equal to the z - score
Substituting this value into the z-score formula to obtain the score(x) which seperates the lower 5%(0.05) from the rest of the class
z = (x - m) / sd
-1.645 = (x - 73) / 10.6
-1 645 * 10.6 = x - 73
-17.437 = x - 73
-17.437 + 73 = x
55.563 = x
Therefore, the score which seperetes the lower 5% from the rest of the class is 55.563
