To find the area of a regular figure,the formula would be:

s^2(n)/4tan (180/n)

where
s is the length of any side
n is the number of sides

In this case:
12^2(6)/4tan (180/6)
=144/4tan(30)
=144/120tan
≈374.1 in^2 (correct to the nearest tenth)

Hope it helps!

On an eight question true-false quiz, a student guesses each answer. What is the probability that he/she gets at least one of th

Fantom [35]

Answer:

$P[at\ least\ 1] = 0.9961$

Step-by-step explanation:

Given

$Questions = 8$

$Quiz\ Type = True\ or\ False$

Required

Probability that s/he gets at least one correctly

First, we calculate the probability of answering a question correctly

Since, there are just 2 choices (true or false), the probability is:

$P(correct) = \frac{1}{2}$

Similarly, the probability of answering a question, wrongly is:

$P(wrong) = \frac{1}{2}$

The following relationship exists, in probability:

$P[at\ least\ 1] = 1 - P[none]$

So, to calculate the required probability.

First, we calculate the probability that he answers none of the 8 questions correctly.

$P[none] = p(wrong)^8$

$P[none] = (\frac{1}{2})^8$

Substitute $P[none] = (\frac{1}{2})^8$ in $P[at\ least\ 1] = 1 - P[none]$

$P[at\ least\ 1] = 1 - (\frac{1}{2})^8$

$P[at\ least\ 1] = 1 - \frac{1}{256}$

Take LCM

$P[at\ least\ 1] = \frac{256 - 1}{256}$

$P[at\ least\ 1] = \frac{255}{256}$

$P[at\ least\ 1] = 0.9961$

<em>Hence, the probability that s/he gets at least one correctly is 0.9961</em>

Which answer choice correctly identifies the missing information in the problem? Joey and Kirk are in the 6th grade. Kirk is 5 f

user100 [1]

Answer:Kirk is taller than Joey by 8 inches

Step-by-step explanation:

Step 1

Kirk's height is given as =5 feet 4 inches tall.

Joey's height 4 feet 8 inches tall

Difference in height = 5 feet 4 inches

- 4 feet 8 inches

Step 2

Bear in mind that 12 inches = 1 feet . Now,8 cannot be subtracted from 4 , so we borrow 1 feet from 5feet, which is equivalent to 12 inches and add to inches so it becomes

4 feet (12+4)inches = 4 feet 16inches

- 4 feet 8 inches - 4 feet 8 inches

= 8 inches

Therefore Kirk is taller than Joey by 8 inches
