Probability
In statistics, probability deals with the possibility of happening of the events.
Given,
Here we know that the throw a fair die three times. if we observe the first throw is a 4.
And we need to find the probability that there is at least two 4s in the three throws.
According to the given question, we know that the dice is thrown 3 time.
Then the sample space of the given event is 216.
Here we know that the first throw has 4.
And we need to find the probability of getting two 4s in the 3 throws,
So, the possible number of events are.
=> {444, 441, 442, 443, 445, 446, 414, 424, 434, 454, 464}
So, the total possible number is 11.
Then the probability is,

The correct answer is 64
Demoivre's theorem states that for all complex numbers z and all positive integers n:
z^n = (r^n) × (cos(n∅) + isin(n×∅))
where r is the magnitude of z and theta is the argument of z.
To use Demoivre's theorem to simplify (1−i)^12, we can first write (1−i) in polar form as r × cis(∅). where r is the magnitude and cis(∅) is the size complex number. is 1, the argument ∅. In this case the size of (1−i) is √(1^2 + (-1)^2) = √(2) and the argument of (1−i) can be found using the arctangent function.
∅ = arctan(-1÷1) = -45 degrees.
So (1−i) can be written as sqrt(2) × cis(-45 degrees). Applying this to Demoivre's theorem, we get:
(1−i)^12 = (√(2)^12) × (cos(-540°) + i×sin(-540°))
We can simplify this to:
(1−i)^12 = 2^6 × cis(-180°)
This can be further simplified as follows.
(1−i)^12 = 64 × (-1)
the final answer is -64.

The parabola's vertex has the equation y = x² - 8x + 12 is (4, -4).
Define parabola.A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line. A plane curve created by a point moving so that its distance from a fixed point equals its distance from a fixed line is known as a parabola. A normal parabola's standard equation is y 2 = 4 an x, where an is the distance from the vertex to the focus.
Given,
Function,
y = x² - 8x + 12
The supplied equation's vertex must be located.
The equation is a parabolic equation when we look at it.
We are aware that a parabolic equation's generic form is
y = x² - 8x + 12
where the parabola's vertex's x and y coordinates are denoted by h and k.
We can determine the following by comparing the aforementioned equation with the parabola's general form:
x = 4, y = 4 and h = -8
The parabola's vertex has the equation y = x² - 8x + 12 is (4, -4).

Write the equation in standard form for the circle that has a diameter with endpoints (-2,10) and (-2,8)
The equation in standard form for the circle will be;
⇒ (x + 2)² + (y - 9)² = 1
What is Circle?
The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The circle that has a diameter with endpoints (-2,10) and (-2,8).
Now,
Since, The circle that has a diameter with endpoints (-2,10) and (-2,8).
Hence, The radius of circle is the half of the distance between two points of the diameter.
So, Radius = 1/2 (√ (8 - 10)² + (- 2 - (-2))²
= 1/2 √4
= 1/2 × 2
= 1
Thus, Radius (r) of circle = 1
And, The center of circle is midpoint of the endpoints of the diameter.
Hence, Centre = (- 2 + (-2))/2, (10 + 8)/2
= - 4/2 , 18/2
= (- 2, 9)
Hence, The equation of circle with center (-2, 9) and radius 1 is;
⇒ (x - (-2))² + (y - 9) = 1²
⇒ (x + 2)² + (y - 9)² = 1

The 33rd percentile is 75.4.
Percentile is defined as the value below which a given percentage falls under. The percentile formula is used when we need to compare the exact values or numbers over the other numbers from the given data i.e. the accuracy of the number.
To find the percentile, here are a few steps to use the percentile formula. If q is any number between zero and hundred, the qth percentile is a value that divides the data into two parts i.e the lowest part contains the q percent of the data and the rest of the data is the upper part.
We find the rank.
Rank = Percentile ÷ 100
Rank = 33 ÷ 100 = 0.33
So, the rank is 0.33.
Using the percentile formula,
Percentile = Rank × Total number of the data set
Percentile = 0.33 × 117
Percentile = 38.61 ≅ 39
Now, counting 39 values from left to right we reach 75.4, and we can say that all the values below 75.4 will come under the 33rd percentile. In other words, 33% of the values are below 75.4.
Therefore, the 33rd percentile is 75.4.

The area of the circle is 66.50cm²
How to calculate the area of the circle?A circle is an object in which all distances are equal from the center.
In a circle, the length of the two tangents are equal.
From the figure, BP=CP
Also, the angles between a tangent and a radius is = 90⁰
⇒<OCP=90⁰
<PCB=<PBC=(180-60)/2 = 120/2 = 60⁰
Using cosine rule,
p²=b²+c²-2bccosP
p²=8²+8²-2*8*8*cos60
p²=64+64-128*0.5
p²=128-64
p²=64
Take the square root of both sides to get
p=√64=8
Note that CB=8 .....................(given)
Cx=8/2=4cm
Using trigonometric ratio
CosC = Adjacent/Hypotenuse
Cos30 = 4/CO
CO = 4/cos30
CO = 4/0.8660
CO = 4.6cm
CO = radius (r)

If at a store 4% of the eggs are cracked and you buy a dozen, then the probability that at least 1 is cracked is 0.916
The probability that the egg is cracked = 4%
= 0.04
The probability that the egg is not cracked = 1 - 0.04
= 0.96
Total number of eggs = 12 eggs
The probability that the one egg is cracked = 12 × 0.04 × (0.96)^11
= 0.306
The probability that 0 eggs are cracked = 1 × 0.04^0 × 0.96^12

Calculate the monthly share of annual expenses and find the total monthly expenses.
1. Annual, $4,200; Living, $670; Fixed, $800
The monthly share of annual expenses is $1820/month.
What is a monthly share?The monthly Share is calculated by dividing the annualized net amount of non-monthly billed services by 12.
Nonrecurring billing:
A one-time transaction is a non-recurring payment.
There is usually only one invoice or bill involved, and it only happens once.
Frequently, the amount is greater than the sum for recurring payments.
Subscriptions that are on monthly billing are billed on the same day each month for as long as the subscription is current.
So, we have:
Annual: $4200
Living: $670
Fixed: $800
Now, calculate as follows:
4200/12 = 350
Then,
350 + 370 + 800 = $1820/month

How to find the value of x?
If a line is divided into two angles, we can always find the other angle if we know the first, many angles on one side of a straight line can be handled with this method.Angles in a straight line are the total of all the angles that can be arranged in a straight line.Standing with your back to the North and turning to face East equals a 90° clockwise turn. If you turn 90 degrees more clockwise, you'll find yourself looking south. If you were to make two more turns like this, you would first face West and then North (the full turn). Therefore, a half turn is two lots of 90 degrees, or 180 degrees.A straight line's angles add up to 180 degrees.The angle of straight line will be 180°
119° + x = 180°
x = 180° - 119°
x = 61°

The measure of the required angle of the given rhombus ABCD is m∠ADC = 64°.
Properties of a rhombus:In a rhombus, the opposite angles are equal in measure.The diagonals in a rhombus are the angle bisectors.The two diagonals bisect each other.The adjacents angles of a rhombus are supplementary.Calculation:The given rhombus has four angles as
∠ADC, ∠DCB, ∠CBA, and ∠BAD
It has two diagonals that bisect each other at point E.
And we have ∠ABD = 32° and ∠ACD = 58°
Here, the angles ∠ABD and ∠BDC are alternate angles. Since we know that, the alternate angles are equal in measure, we can write
∠ABD = ∠BDC
⇒ 32° = ∠BDC
Since we know that the diagonals of a rhombus bisect the angles, we get
∠ADC = 2∠BDC
⇒ ∠ADC = 2 × 32° = 64°
Therefore, the required angle of the rhombus is ∠ADC = 64°.

so the null hypothesis is H₀ : μ = 11 pounds
and the alternative hypothesis is Hₐ : μ > 11 pounds
now we will calculate test statistics,
t = (x-μ)/(σ/√n)
= (12 - 11)/(4/√25)
= 1/(4/5)
t = 1.25
p-value from the z-table is 0.10565
the result is non significant at p < 0.01.
Hence the null hypothesis rejected .
Therefore there is enough evidence to conclude that the doctor's claim is true.
The level of significance is the measurement of the statistical significance. It defines whether the null hypothesis is assumed to be accepted or rejected. It is expected to identify if the result is statistically significant for the null hypothesis to be false or rejected.
