$P(X\geq10)=P(X=10)+P(X=11)+P(X=12)=\binom{12}{10}p^{10}(1-p)^2+\cdots=73.95\%$

A 15-m2 wooded area has the following: 30 ferns, 150 grass plants, and 6 oak trees. What is the population density per m2 of eac

swat32

Answer:

See the procedure

Step-by-step explanation:

we know that

To find the population density per m² of each of the above species, divide the amount of each species by the total area

so

<em>Ferns</em>

$\frac{30}{15}=2\frac{ferns}{m^{2}}$

<em>Grass plants</em>

$\frac{150}{15}=10\frac{grass\ plants}{m^{2}}$

<em>Oaks Trees</em>

$\frac{6}{15}=0.4\frac{oaks\ trees}{m^{2}}$

Given that sin(90 -5ϴ) = Cos(180 - ϴ), Find the value of ϴ<br>

lilavasa [31]

Answer:

30°

Step-by-step explanation:

$\because \: \sin(90 \degree - \theta) = \cos \theta \\ \therefore \: \sin(90 \degree - 5 \theta) = \cos 5\theta....(1) \\ \\ \sin(90 \degree - 5 \theta) = \cos(180 \degree - \theta)...(2) \\ from \: (1) \: and \: (2) \\ \cos 5\theta = \cos(180 \degree - \theta) \\ 5 \theta = 180 \degree - \theta \\ 5 \theta + \theta= 180 \degree \\ 6\theta= 180 \degree \\ \theta = \frac{180 \degree}{6} \\ \\ \huge \red{ \boxed{\theta = 30 \degree}}$
