Consider a circle whose size can vary. The circumference of the circle is always 2 π 2π times as large as its radius. Let r r re

Alenkasestr [34]

Answer: $C=2\pi r$

Step-by-step explanation:

Let be "C" the circumference of the circle (in feet) and "r" the radius of the circle (in feet).

Based on the information provided in the problem, you know that the circumference of the circle is always $2\pi$ as large as its radius.

Notice that this indicates a multiplication. Then, this means that the circumference of the circle is always equal to $2\pi$ by "r".

Based on this, you can write the following formula that expresses the circumference "C" in terms of the radius "r":

$C=2\pi r$

Standard deviation of 300, 785, 670, 187, 760, 724

White raven [17]

STEP 1

Mean = $\frac{300+785+670+187+760+724}{6} = \frac{3426}{6}=571$

STEP 2

Subtract the mean from each data value then square the answer
$300-571=-271$ ⇒ $(-271)^{2} =73441$
$785-571=214$ ⇒ $(214)^{2}=45796$
$670-571=99$ ⇒ $(99)^{2}=9801$
$187-571=-384$ ⇒ $(-384)^{2} =147456$
$760-571=189$ ⇒ $189^{2}=35721$
$724-571=153$ ⇒ $153^{2} =23409$

STEP 3

Add the squared answers in STEP 2 then find the mean

$\frac{73441+45796+9801+147456+35721+23409}{6}= \frac{335624}{6}=55937.3$

STEP 4

Square root the answer in STEP 3
$\sqrt{55937.3} =236.5$

Standard deviation is 236.5

Loveland Colorado, is 18 km due south of Fort Collins and 31 km due west of Greeley, What is the distance between Fort Collins a

GalinKa [24]

Answer: The distance between Fort Collins and Greeley is 35.84 km.

Step-by-step explanation:

Since we have given that

Distance travelled due south of Fort Collins = 18 km

Distance traveled due west of Greeley = 31 km

So, using the pythagorous theorem, we will find the distance between Fort Collins and Greeley.

So, it becomes,

$H^2=B^2+P^2\\\\H^2=18^2+31^2\\\\H^2=324+961\\\\H^2=1285\\\\H=\sqrt{1285}\\\\H=35.84\ km\\\\$

So, the distance between Fort Collins and Greeley is 35.84 km.
