The number of contaminating particles on a silicon wafer prior to a certain rinsing process was determined for each wafer in a sample of size 100, resulting in the following frequencies: Number of particles 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Frequency 1 3 3 12 11 15 17 10 12 4 5 3 1 2 1 (a) What proportion of the sampled wafers had at least one particle? At least five particles? (Round your answers to two decimal places.)

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
