Law Incorporation [45]

Answer: (6-9) Hatchlings would be a reasonable outcome for the simulation.

As the histogram shows the number of chicks born to non-migratory Canada geese in a city park, with the horizontal axis representing the number of hatchlings and the vertical axis representing the number of nests.

In order to monitor the geese population, the state wildlife service annually samples the number of hatchlings from 30 nests using a simulation= 6-9 hatchlings.

(As there is only 1 bar with (6-9)hatchlings which is meeting to the 30 nests on y axis)

In circle S,diameter PN is drawn .If measurement arc MN=110 degrees and PS=10 then find the length of MN to the nearest tenth.Sh

Goryan [66]

Answer:

$MN=16.4\ units$

Step-by-step explanation:

step 1

Find PN

we know that

PN is a diameter

PS is a radius

$PS=10\ units$

$PN=2*PS=2*10=20\ units$

step 2

Find the measure of arc MP

$arc\ MN+arc\ MP=180\°$

$arc\ MN=110\°$

$arc\ MP=180\°-110\°=70\°$

step 3

Find the measure of angle MNP

we know that

The inscribed angle measures half that of the arc comprising

substitute the value

step 4

Find the measure of angle MPN

we know that

The inscribed angle measures half that of the arc comprising

substitute the value

step 5

Find the measure of angle NMP

The sum of the internal angles of a triangle must be equal to 180 degrees

therefore

The triangle MNP is a right triangle

step 6

Find the length MN

In the right triangle MNP

$sin($

substitute the values

$sin(55\°)=\frac{MN}{20}$

$MN=(20)sin(55\°)=16.4\ units$

Adam is using the equation (x)(x + 2) = 255 to find two consecutive odd integers with a product of 255. When Adam solves the pro

kondaur [170]

$\bf (x)(x+2)=255\implies x^2+2x=255\implies x^2+2x-255=y
\\\\
\textit{setting y=0}\implies x^2+2x-255=0
\\\\
\textit{now, factoring that}
\\\\
(x+17)(x-15)=0\implies 
\begin{cases}
x=-17\\
x=15
\end{cases}$

notice the picture of the graph added here
low and behold, x = -17, y is 0, and x= 15, y is 0
the graph is touching the x-axis, an x-intercept
or so-called, a "solution"

A sports car and a minivan run out of gas and are pushed to the side of the road. Which is easier to push, and why?

nirvana33 [79]

Answer:

The sports car, because it has less mass and therefore less inertia

Step-by-step explanation:

When an object has less inertia it is easier to be put into and out of motion, and a sports car would obviously weigh less than a van.
