Answer:
width = 16 cm
length = 19 cm
Step-by-step explanation:
Let the width be x cm.
Given that length is 3 cm more than width then
length = x+3 cm
area of rectangle = 304 square cm. -----1
area of rectangle is given by
area =length * width
substituting from equation 1 and length and width in terms of x we have
304 = x(x+3)
As length cannot be negative hence x = 16
Thus width = x = 16 cm
length = x+3 = 16+3 = 19 cm
The product is less than either of the factors. Multiplying a number < 1 with 2/3 another number < 1, will give a fraction of a fraction, and part of a fraction is an even smaller fraction. Another way of looking at it: Fractions less than one have numerators smaller than their denominators. When multiplying fractions, you multiply across, so multiplying two fractions that are both less than one will always give a numerator much smaller than the denominator, and a larger denominator makes for a smaller number.

True mean = mean+/- Z*(SD/sqrt (n))
Where
Z = 1.96 at 95% confidence interval
Mean = 10.3 pounds
SD = standard deviation = 2.4 pounds
n= sample size = 37 packages
Substituting;
True mean range = 10.3+/- 1.96 * 2.4/Sqrt (37) =10.3+/- 0.77 = 9.53<mean<11.07
