The sample is based on the first 25 parents dropping off actors during theater rehearsal hence the sampling method is non random and biased.

A non random sample refers to a sampling method that is not based on chance alone. A biased sampling is one in which some members of the population are more likely to be selected thereby excluding the others.

Since the sample is based on the first 25 parents dropping off actors during theater rehearsal, the sampling method is  non random and biased.

The circumference of a circle is 15n cm what is the area of the circle in terms of n
Mice21 [21]

Answer:

Area of circle is \dfrac{225n^{2}}{4\pi} cm^{2}

Step-by-step explanation:

Formula for circumference of circle is given as,

C=2\pi r

Given that C = 15 n cm,

Substituting the value,

15n=2\pi r

Solving above equation for r, divide both side by 2\pi

\dfrac{15n}{2\pi}=\dfrac{2\pi r}{2\pi}

Simplifying,

\dfrac{15n}{2\pi}=r

Formula for area of circle is given as,

A=\pi r^{2}

Substituting the value of r,

A=\pi \left(\dfrac{15n}{2\pi}\right)^{2}

Squaring the parenthesis,

A=\pi \left(\dfrac{225n^{2}}{4\pi^{2}}\right)

Cancelling out the common term,

A=\dfrac{225n^{2}}{4\pi}

Therefore, area of circle in terms of n is A=\dfrac{225n^{2}}{4\pi} cm^{2}

5 x negative 3 plus 2X equals 41
DaniilM [7]
<span>5(x - 3) + 2x = 41
</span>distribute the 5 to both x and -3

5x - 15 + 2x = 41

5x + 2x - 15 (+15) = 41 (+15)

5x + 2x = 41 + 15

7x =  56

7x/7 = 56/7

x = 8
