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

Consider this right triangle with given measures.

OlgaM077 [116]

Answer:

$\sqrt{39}$

Step-by-step explanation:

I think the answer choices were supposed to be:

$\sqrt{3} , \sqrt{6} , \sqrt{39} , \sqrt{89}$

Pythagorean Theorem: a²+b²=c²

5²+b²=8²

25+b²=64

<em>Subtract 25 from both sides</em>

b²=39

<em>Square root both sides</em>

b= $\sqrt{39}$

Our answer is $\sqrt{39}$
