The scale factor of the smaller figure to the larger figure is 4/25
<h3>Scale factors</h3>
Scale factors is used to enlarge or diminish the size of an object. The rato of the sides or volume of the figures is the scale factor.
Given the following
Surface area of small cylinder = 20πyd²
Surface area of large cylinder = 125πyd²
find the ratio
Scale factor = 20π/125π
Scale factor = 4/25
Hence the scale factor of the smaller figure to the larger figure is 4/25

= 2¹/₂ = 5/2
Quantity that Elijah has:
= Number of bags * Weight per bag
= 5/2 * 55
= 137.5 pounds
The 80 th percentile simply corresponds to the P value =
0.80 or the area which comprises 20% from the right of the standard curve. So
from the standard normal tables, the z score at 80 th percentile is given as:
