Answer:
A. People who are related to the employees of Isaac's Immaculate Ice Cream
Step-by-step explanation:
If the results are called into question, this means there is potential bias in the survey.
Randomly choosing people from a phone book or another random method would not create bias.
Having people blindly test brands of ice cream would not create bias, as it is random and fair.
However, if the people surveyed were related to employees of Isaac's Immaculate Ice Cream, the results could be called into question over a fear of favoritism.
a
I searched and found this figure online.
I'm guessing there's additional information that OM perpendicular to CD and EF perpendicular to ON.
The diameters meeting chords at right angles also bisect the chords, so
CM = (1/2) CD = 28
The radius OC makes the hypotenuse of a right triangle with legs OM and CM
r² = OM² + CM² = 20² + 28² = 1184
r = 4√74
a Answer: 4√74
b
FN is the leg of a right triangle with other leg ON=16 and hypotenuse OF=r because it's a radius.
FN² = r² - ON² = 1184 - 16² = 1184 - 256 = 928
FN = √928
b Answer: √928
c
EF is twice FN by the perpendicular diameter bisecting a chord theorem.
EF = 2√928
Tenths?
c Answer: 60.9
