A circle of radius 4.6 cm is drawn with its center at the origin. The diameter XY of the circle is also drawn, along with two chords XP and YQ connecting the endpoints of the diameter.
A circle of radius 4.6 cm is drawn with its center at the origin, which is labeled as O. The diameter XY of the circle is also drawn and labeled, with the endpoints X and Y. Two chords XP and YQ are then drawn connecting the endpoints of the diameter. The chord XP starts at X and ends at P, while the chord YQ starts at Y and ends at Q. This diagram demonstrates the idea of a circle and its diameter, as well as how two chords can be drawn from the same two endpoints of a diameter. The circle and its diameter can also be used to calculate the circumference of the circle and the length of the diameter.
Circumference of circle = 2 * π * 4.6 = 28.96 cm
Length of diameter = 2 * 4.6 = 9.2 cm

The dimensions of the closet are 4 feet long and 12 feet wide and the perimeter is 32 feet
What is the perimeter of a rectangle?The perimeter of a two-dimensional shape is the total length of the outline. To find the perimeter of a rectangle, we add the lengths of all four sides.
P=2(l+w) where l=length and w = width
Given here rectangular closet is 4 feet long and It is 3 times as wide as it is long. Thus its width would be 12 feet
Now perimeter of the closet using the formula above we get
P = 2(4+12)
= 32 feet
Hence the perimeter is equal to 32 feet.

On translating n 1 unit right and 4 unit up , we get the coordinates of B as B'( 3, 9).
The given triangle ABC has the following vertices A(1, 3), B(2, 5), and C(5, 3).
We will apply the translation rule on the following triangle,

Based on these results, express the probability that the next person will purchase

The probability that the next person will purchase exactly one costume is 0.57.
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:
146 visitors purchased no costume.
230 visitors purchased exactly one costume.
31 visitors purchased more than one costume.
So, the total number of customers are,
146 + 230 + 31 = 407
The total visitors purchased exactly one costume are 230.
So,
P(Purchase exactly one costume) = 230 / 407 = 0.5651 ≈ 0.57
Hence, the probability that the next person will purchase exactly one costume is 0.57.

Therefore, the work done in this problem comes out to be 144 ft pound.
Where is the work done?The work a force does is calculated as the product of the object's displacement and the components of the applied force of the object in the displacement direction. Pushing a block with some force and accelerating the body results in work being completed.
Here,
Given : an 8 lb mass
a height = 18ft
So, we find the work done
Using formula
=> Work done = m*g*h
=> Work done = weight * height
=> Work done = 8*18
=> Work done=144 ft pound
Therefore, the work done in this problem comes out to be 144 ft pound.

Step-by-step explanation:
You have 924 people classified as 383 men, 356 women, and the remainder children. 2/5 of the children are boys, and you want to know the number of girls.
GirlsThe number of children is ...
924 -383 -356 = 185
The 3/5 of children that are not boys are girls, so ...
girls = 3/5(185) = 111

if the probability that a baby born in a certain hospital will speak in the next day is , what is the probability that at least babies out of a cluster of babies will speak tomorrow?
The probability that at least 2 babies out of a cluster of 5 babies will speak tomorrow is 47/128.
The probability that less than 2 babies will speak is
5C0 * (0.25)^0 * (0.75)^5 + 5C1 * (0.25)^1 * (0.75)^4
= (0.75)^5 + 5 * 0.25 * (0.75)^4
(0.75)^5+5*0.25*(0.75)^4 = 81/128
Therefore,
probability that 2 or more will speak is
= 1- 81/128 = 47/128
The binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and having its own Boolean-valued outcome: success (with probability p) or failure (with probability display style q=1-pq=1-p).
This distribution is used in probability theory and statistics. A Bernoulli trial, or experiment, is another name for a single success-or-failure experiment, and a Bernoulli process is another name for a series of results.

What is the Pythagorean theorem? How do you use it to find the length of a missing side in a right triangle? Give an example and show your work.
The sum of squares of two sides of a triangle is equal to another side of a triangle is called the Pythagorean theorem.
It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
c^2=a^2+b^2--------(1)
Where a,b, and c are sides of a triangle.
To measure the length of the missing side in a right triangle using the Pythagorean theorem:
c^2=a^2+b^2
By using this formula we can find the length of a missing side.

The measure of the angle ∠ACD will be 150°. Then the correct option is D.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The internal angles ∠A is 33° and ∠B is 117°.
Then the measure of the internal angle ∠C is given as,
∠A + ∠B + ∠C = 180°
33° + 117° + ∠C = 180°
∠C = 30°
The angle ∠C and angle ∠ACD are supplementary angles. Then we have
∠C + ∠ACD = 180°
30° + ∠ACD = 180°
∠ACD = 150°
The measure of the angle ∠ACD will be 150°. Then the correct option is D.
