What are the theorems we can use?  

Probably the most relevant is the angle at a point on the circle subtended by a chord has a measure equal to half the arc indicated by the chord.

By the theorem,

angle AEB = angle ADB = (1/2) arc AC = (1/2) 110 = 55 deg

angle BAE = angle DBE = (1/2) arc DE = (1/2) 130 = 65 deg

angle BKD + angle KDB + angle DBK = 180 deg

angle BKD + angle ADB + angle DBE = 180 deg

angle BKD = 180 - 55 - 65 = 60 degrees

Answer: 60 degrees

A monk crossbred plants which can have purple or white flowers and obtained 511 plants with white flowers and 337 plants with pu
Zepler [3.9K]

Answer:

For purple;

P(p) = 337/848 = 0.40

For white;

P(w) = 511/848 = 0.60

Step-by-step explanation:

Given;

Number of plants with purple flowers P = 337

Number of plants with white flowers W = 511

Total T = 337 + 511 = 848

For purple;

the empirical Probability that a plant had purple flowers P(p) is

P(p) = Number of plants with purple flowers/total number of plants

P(p) = P/T

Substituting the values, we have;

P(p) = 337/848 = 0.40

For white;

the empirical Probability that a plant had white flowers P(w) is

P(w) = Number of plants with white flowers/total number of plants

P(w) = W/T

Substituting the values, we have;

P(w) = 511/848 = 0.60
