Angles in a line = 180
180-165 = 15 degrees

15 + 45 + ? = 180
60 + ? = 180
? = 120

What is the volume of the cylinder

Harman [31]

The volume of a cylinder is given by

$V = A_b\cdot h$

where $A_b$ is the base area, and $h$ is the height.

We are already given the height, which is 10.

We can deduce the base area since we are given a diameter: the radius is half the diameter, so it's 8, and the area of a circle is given by

$A_b = \pi r^2 = \pi 8^2 = 64\pi$

So, the volume is

$V = A_b\cdot h = 64\pi \cdot 10 = 640\pi \approx 2010.6193\ldots$

Astronomers treat the number of stars X in a given volume of space as Poisson random variable. The density of stars in the Milky

cupoosta [38]

Answer:

Explained below.

Step-by-step explanation:

The random variable X is defined as the number of stars in a given volume of space.

$X\sim \text{Poisson}\ (\lambda=1)$

The probability mass function of X is:

$p_{X}(x)=\frac{e^{-\lambda}\lambda^{x}}{x!}$

Compute the probability of exactly two stars in 16 cubic light-years as follows:

$P(X=2)=\frac{e^{-1}\times 1^{2}}{2!}=\frac{e^{-1}}{2}=\frac{0.36788}{2}=0.18394\approx 0.184$

(8)

Compute the probability of three or more stars in 16 cubic light-years as follows:

$P(X\geq 3)=1-P(X$

(9)

In 16 cubic light years there is only 1 star.

Then in 1 cubic light years there will be, (1/16) stars.

Then in 4 cubic light years there will be, 4 × (1/16) = (1/4) stars.

(10)

In 16 cubic light years there is only 1 star.

Then in 1 cubic light years there will be, (1/16) stars.

Then in t cubic light years there will be, [t × (1/16)] stars.

Answer:

$a \\ \frac{50}{0.25} = 200 \: \frac{km}{ {h}^{2} } \\ b \\ the \: area \: under \: graph = whole \: distance = \\ = 50 \times (2 + 1.5) \times 0.5 + \\ + 50 \times (0.5 + 1) \times 0.5 = 125km \\ c \\ \ \: average \: speed \: = \frac{125}{2} = 62.5 \frac{km}{h}$

Can someone do both #23, and #24 (show your work please)

Lisa [10]

23) It is right angle triangle, so the sum of acute angle must be equal to 90

sum of ratio units = 2+7 = 9

value of 1 unit = 90/9 = 10

measures of angle would be 2(10) & 7(10) = 20 & 70

Measure of smaller angle is 20

24) It is only graphical work. You have to do it on your own cause I can't show you here, sorry!!
