One of the most spectacular and least known hummingbirds is the Marvelous Spatuletail, Loddigesia mirabilis, found in only in a

single remote valley in northern Peru (see photo below). In this valley the mean density is 3 spatuletails per 100-hectare quadrat. (a) What is the probability a random quadrat contains less than 3 spatuletails

Answer:

P(x < 3) = 0.42319

Step-by-step explanation:

From the given information:

The mean density \lambda = 3

Let x be the random variable that follows a Poisson distribution.

Therefore:

\mathtt{P(x) = \dfrac{e^{-\lambda} \lambda ^x}{x!}}     for x =1, 2, 3...

However, the probability that a random quadrat contains less than 3 spatuletails can be computed as:

\mathtt{P(x

\mathtt{P(x

\mathtt{P(x

\mathtt{P(x

\mathtt{P(x

P(x < 3) = 0.42319

What is m∠A ?<br> Please see attachment <br> (The Triangle Sum Theorem)
goblinko [34]
The triangle sum theorem says all 3 interior angles must equal 180 degrees.

so, 43 + 35 = 78.  [ 180 - 78 = 102 degrees for the missing angles shared by the 2 triangles.

102 + 18 = 120.  [180 - 120 = 60}

leaving the measure of Angle A as 60 degrees.

Answer:

Step-by-step explanation:

Let's see how well I can explain this. \frac{\pi}{6} is the same as a 30 degree angle which is in quadrant 1. If you picture the unit circle, right in the center of it is the origin. If you draw a straight line from 30 degrees and through the center (the origin), you will automatically "connect" with the reference angle of 30 (this is true for ALL angles on the unit circle). This puts us in quadrant 3. In quadrant 3, x is negative and so is y. So the terminal point of the reference angle for 30 degrees has the same exact values, but both of them are negative (again, because both x and y are negative in quadrant 3). I can't see your choices but the one you want looks like this:

(-\frac{\sqrt{3} }{2},-\frac{1}{2})

Y=kx
12=-4k
  k = -3

so when y = 15
y = kx
15 = -3x
  x = -5

----------------

$50 / 0.04 = $1250 (4% interest)

so
1250 * 0.06 = $75

answer
interest $75 at 6%

-----------------------------

y = kx
1/4 = 4k
k = 1/16

when x = 5
y = kx
y = 1/16(5)
y = 5/16 

-----------
y = kx
-5 = 4k
k = -5/4

direct equation
y = -5/4x
