10. What is the side length of a regular
36-gon that has an area of 164,592
square meters and an apothem of
228.6 m?

Answer:

Here are 5 ordered pairs whose first and second coordinates are equal:

(2,2)

(3,3)

(4,4)

(5,5)

(6,6)

If we plot these points and connect them, we get a straight line that runs from the bottom left to the top right of the coordinate plane. This line is called the "diagonal" of the coordinate plane and it divides the plane into 4 quadrants.

The figure that we get lies in all 4 quadrants of the coordinate plane. The top right and bottom left quadrants are the "positive" quadrants, where both the x- and y-coordinates are positive. The top left and bottom right quadrants are the "negative" quadrants, where both the x- and y-coordinates are negative.

The required probability that the spinner and number cube both lands on number 2 is 1/4. Option E is correct.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Total sample space = 4 × 6 = 24
Favorable event  = (2, 2) = 1
The probability that the spinner and number cube both lands on number 2,
= favorable outcome/sample space
= 1 / 24

Thus, the required probability that the spinner and number cube both lands on number 2 is 1/4. Option E is correct.

Answer:

Samantha has a total of 12 chickens. if she has 3 times as many chickens as dogs. The correct answer is 3x = 12; x = 4.

Samantha has a total of 12 chickens. if she has 3 times as many chickens as dogs.  First you have to divide by 3 on both sides.

Therefore, Samantha has a total of 12 chickens. if she has 3 times as many chickens as dogs. The correct answer is 3x = 12; x = 4.

The volume of the solid cone obtained by rotating the region bounded by the line y=12x, y=0, and x=4 about the x-axis is 38603.89 [tex]unit^{3}[/tex]

We will calculate the volume in the following way,

Given lines are: x=4, y=0, y=12x

First, we make a triangle from the given equation and then rotate it along the x-axis to get the dimensions of the cone.

We, need to put x=4 and y=0 in y=12x to get all the vertices of the triangle.

Points are: (0, 0), (4, 0), and (4, 48).

Now, we rotate this triangle about the x-axis.

Thus, the radius of the cone(r)= 48 and the height of the cone(h)= 4.

Therefore, the formula for the volume of the cone (v)= [tex]\frac{4}{3}*(\pi *r^{2}*h )[/tex]

=[tex]\frac{4}{3} \pi*48^{2}*4[/tex]

=38603.89 [tex]units^3[/tex]

Therefore the volume obtained is 38603.89 [tex]unit^{3}[/tex]

As per the Pythagoras theorem, the number of feet along the ground from the tent pole to the rope is 8 feet.

Here we have given that A 15-foot tall tent pole incurred to the ground using a piece of rope 17 feet long that goes from the top of the tent pole to the ground. If the tent pole make a 90-degree angle with the ground,

And we need to determine the number of feet along the ground from the tent pole to the rope.

AS per the given data, here we have consider that the pole makes 90° with the ground and is supported by a rope.

And for the clear observation, here we can realize that the pole, rope and ground form a right-angled triangle, where

The value of Hypotenuse (h) = length of rope = 17 feet

And the Side 1 (p) = length of tent pole = 15 feet

Then the Side 2 (b) = distance between pole and rope along the ground

Now, we have to applying the Pythagorean theorem, the following equation is obtained:

=> h² = p² + b²

Then we have to apply the values on it, then we get

=> 17² = 15² + b²

=> b² = 289 - 225

Therefore, the value of is calculated as,

=> b = √64

=> b = 8 feet

Therefore the distance between the tent pole and the rope along the ground is 8 feet.

The probability for all sample of 5 that the sample mean will be greater than 22 pounds is approximately 0.05.

The distribution of backpack with mean deviation = 19.7 pounds

And the standard deviation = 3.1 pounds

According to this question,

He normal probability distribution and the central limit theorem were used.

Normal probability distribution, ; Problems of normally distributed samples are solved using the z-score formula.

Mean standard deviation, the z-score of a measure X is given by:

Z = x-μ/σ

The Z-score measures how many standard deviations. the measure is from the mean.

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score.

This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.

Subtracting 1 by the p value,

We get the value probability that of the measure is greater than X.

Central Limit Theorem;  The Central Limit Theorem establishes  that, for a normally distributed random variable X, with mean  and standard deviation the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For samples of size 5, which of the following is the best interpretation of P(ä > 22) = 0.05

No matter the size of the sample mean will be the same.

However, the standard deviation will be changed.

P(ä > 22) is the probability of the sample means being above 22.

For all samples of size 5, the probability that the sample mean will be greater than 22 pounds is approximately 0.05.

When the point N is dilated, the coordinate of N changes to N' ,the coordinate of point N is (8,12).

What is dilation?

In arithmetic, a dilation may be a perform f from a mathematical space M into itself that satisfies the identity d=rd for all points x, y \in M, wherever d is that the distance from x to y and r is a few positive imaginary number.

Main body;

How to determine the coordinate of N

The given parameters are:

N' = (10,15)

k = 5/4

To calculate the coordinate of N, we make use of:

N * k = N'

So, we have:

N * 5/4 = (10,15)

Multiply both sides by 4

N * 5 = (40,60)

Divide both sides by 5

N = (8,12)

Micah's best long jump is 3 meters long.

In this question we have been given Avi and Micah are teammates on a track and field team.

We need to find the how long is Micah's best long jump.

Let Micah's best long jump is x meters and Avi's  best long jump is y meters.

Avi's best long jump is 3 1/2 meters.

⇒ y = 3 1/2 meters

We write this improper fraction as proper fraction.

3 1/2 = 7/2

Also, Avi's best long jump is 1 1/6 times as long as Micah's.

So, we get an equation

y = (1 1/6) * x

We write improper fraction 1 1/6 as 7/6

So equation becomes,

y = 7/6 * x

Subatitute the value of y

7/2 = 7/6  * x

x = (7/2)/(7/6)

x = 6/2

x = 3 meters

The correct answer is a. margin of error.

The margin of error is a measure of the precision of a survey or poll. It represents the range of values within which the true value of the population parameter being measured is likely to fall, based on the sample data collected. A smaller margin of error indicates a higher level of precision and a more reliable estimate of the population parameter. In general, a margin of error of less than +/- 5 is considered to be a good benchmark for a reliable public opinion poll.

The modal response is the most common response to a survey question. The sample size is the number of people included in the survey. Standard deviation is a measure of the dispersion of a set of data. Self-selection bias refers to the possibility that the people who choose to participate in a survey are not representative of the entire population being studied.

The probability the card is red, given that it is a face card is 1/2 and  the probability the card is a king, given that it is a face card is 1/3.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given:

A card is drawn from a standard 52-card deck (no jokers).

We have to match each event with its probability.

Since, a deck of cards contains the face cards J, Q, and K.

Let's say there are four different kinds of cards: spades, clubs, hearts, and diamonds.

King, Queen, and Jack are contained in each of these types.

Thus, the total number of face cards is 12 (3 x 4).

(1)  Let the face cards are 12 and there are 6 red cards in that 12 face cards.

So, the probability the card is red, given that it is a face card is

= 6/12 = 1/2.

(2)  There are 4 king in a 12 face cards.

So, the probability the card is a king, given that it is a face card

= 4/12 = 1/3.

Hence the probability the card is red, given that it is a face card is 1/2 and  the probability the card is a king, given that it is a face card is 1/3.
