The distance of each chord from the centre of the circle are √119 and √128 respectively .
Given,
Radius of a circle = 12 cm
AB = 10 cm
CD = 8 cm
Now, we get
BG = 10/2 = 5 cm
HD = 8/2 = 4 cm
(A perpendicular coming from the centre, which is not a diameter, bisects the chord.)
Now,
BE = ED = EF = 12 cm (All radii of a circle are equal.)
Now, by Pythagoras Theorem, we get
H² = P² + B²
For GE —
(BE)² = (GE)² + (BG)²
or, (12)² = GE² + (5)²
or, 144 = GE² + 25
or, GE² = 144 — 25
or, GE² = 119
or GE = ±√119
or GE = √119 (Since, length cannot be negative.)
For HE —
(DE)² = (HE)² + (HD)²
or, (12)² = HE² + (4)²
or, 144 = HE² + 16
or, HE² = 144 — 16
or, HE² = 128
or, HE = ± √128
or, HE = √128 or 8√2(Since, length cannot be negative.)
Hence , the distance of each chord from the centre of the circle are √119 and √128 respectively .

How many solutions exist for the given equation 3 x 10 6 3 x 12?
There are no solutions for the equation 3x106 3x12.
The equation 3x106 3x12 can be rearranged to 3x106 - 3x12 = 0. This is a linear equation and can be solved using the equation ax+b=0, where a is the coefficient of the variable and b is the constant.
In this case, a = 3 and b = -3x106. To solve this equation, we can use the quadratic formula, which states that x = -b ± √b2 - 4ac / 2a.
Substituting the values for a, b, and c yields x = -(-3x106) ± √(3x106)2 - 4(3)(-3x106)/2(3). Simplifying this yields x = 3x106 ± √9x1012 - 36x1012/6.
This simplifies to x = 3x106 ± √-27x1012/6. Since the square root of a negative number is not a real number, this equation has no real solutions. Therefore, there are no solutions for the equation 3x106 3x12.

Mr. McDonald just bought a farm tractor for $50,000. For tax purposes, its value is expected to
depreciate at a rate of 16% annually. What will the tractor's value be in 4 years? Round to the
nearest hundredth (cent).
Answer:
$24,893.40
Step-by-step explanation:
Year 1
50,000 x 0.16 = 8,000
50,000-8,000 = 42,000
Year 2
42,000 x 0.16 = 6,720
42,000-6,720 = 35,280
Year 3
35,280 x 0.16 = 5644.80
35,280-5644.80= 29,635.2

A drum of oil has a height of 4 feet and a radius of 1.2 feet. The oil cost $22 per cubic feet. What is the cost to fill the drum of oil
The cost of oil to fill the drum with height of 4 feet and a radius of 1.2 feet will be $397.90.
What is cubic feet?An understanding of the different dimensions is necessary to truly understand cubic feet, how big a cubic foot is, and how to measure cubic feet. There are three known dimensions which include a foot measurement. The dimensions expand to include additional measurements with each new dimension.
The cubic foot is an imperial and US customary unit of volume, used in the United States and the United Kingdom. It is defined as the volume of a cube with sides of one foot in length. Its volume is 28.3168 L. At 60 °F, a cubic foot of water weighs 62.37 pounds. A cubic foot (abbreviated as cu ft. or cubic ft.) is an imperial unit of measurement for the volume of a space or three-dimensional object.
Given: A drum of oil has a height of 4 feet and a radius of 1.2 feet. Oil cost has been given as $22 per cubic feet.
We have to calculate the cost to fill the drum with oil.
Since formula to get the volume of the drum is V = πr²h
V = 3.14×(1.2)²×4 = 18.09 feet³
Now the cost of oil to fill the drum will be
Cost = Volume × cost = 18.09×22 = $397.90

c. 100 is not a member of the sequence.
11. a. u₁ is even and d is also even.
b. u₁ is odd and d is even.
What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same constant ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
Given, u₁ = - 12 and uₙ₊₁ = uₙ + 7.
So,
u₂ = u₁₊₁ = - 12 + 7 = - 5.
Similarly, u₃ = - 5 + 7 = 2 and u₄ = 9.
So, The terms have a common difference o 7 and hence it is an arithmetic sequence.
We know, uₙ = u₁ + (n - 1)d.
Therefore, u₂₀₀ = u₁ + (200 -1)×7.
u₂₀₀ = - 12 + 199×7.
u₂₀₀ = - 12 + 1393.
u₂₀₀ = 1382.
Now, Determining whether 1000 is a member of the sequence.
Let, 1000 = - 12 + (n - 1)×7.
1012 = 7n - 7.
1019 = 7n, Here is not completely divisible hence 1000 is not a member of the sequence.
11. When all the terms of an AP is even the first term u₁ is even and the common difference would also be even and when all the terms of an AP are odd the first term u₁ would be odd and the common difference d would e even, as odd - odd = even.

error of the distribution of sample proportions?
A. 0.008
B. 0.084
C. 0.115
D. 0.141
Answer:
b
Step-by-step explanation:
The standard error of the distribution of sample proportions is 0.084
The correct option is (B).
What is standard error?Standard error is calculated by dividing the standard deviation of the sample by the square root of the sample size.
Given: population parameter: 0.7, n=30
Standard error: √[p (1 - p) / n]
= √[0.7 (1 - 0.7) / 30]
= √[0.7*0.3 / 30]
= √0.21 / 30
= √0.007
=0.0836

a) What is the probability that 3 or more copies will be demanded in a particular day?
The probability that 3 or more copies will be demanded in a particular day is 0.64.
What is probability?
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
The probability for 3 or more copies to be demanded is the sum of all the probability distributions for 3 or more copies demanded per day.
This can be written in an equational form -
P(x) = 0.14 + 0.12 + 0.10 + 0.08 + 0.07 + 0.06 + 0.04 +0.03
P(x) = 0.64

When two rotations are performed on a single figure, the order of the rotations never affect the location of the final image.
What is the rotation?In mathematics, rotation is defined as that of the circular movement of an object around with a center, an axis, or a fixed point. Since rotations are rigid transformations, the size, length, shape, and angle measurements of the figure are maintained.
Precession, nutation, and intrinsic rotation are the names of these rotations. The rotation of the earth on its axis is one of the greatest instances of rotation in nature.
There are broad guidelines for rotations of 90, 180, and 270 degrees around the origin that are both clockwise and anticlockwise. Counterclockwise. X and Y are rotated by 90 degrees that means (x , y) ----> (-y , x); Rotation of 180 degrees: (x, y) —- (-x , -y); Rotation of 270 degrees: (x, y) —- (y , -x).
Here two times rotation means 180 degrees that means no change in the final image.

Estimate using compatible numbers.
The length of each of the four walls of the birdhouse is 5.5 inches, so the total length of all four walls is approximately 4 x 5.5 = 22 inches. Therefore, Javi's board is long enough to be cut into the four walls of the birdhouse.
What is the wall equation?Walls. Utilize the conventional equation Length x Width = Area to get the area of a wall. Next, apply the same calculation to each window and door's specific area. Subtract the area of the windows and doors from the overall size of the wall once you have recorded all of these dimensions.
The birdhouse must have four walls that are each 5.5 inches thick.
one room needs four walls because of the length of its four walls.

(2x - 9)² = (2x)² - 2(2x)(9) + (9)²
(2x - 9)² = 4x² - 36x + 81
Thus, The product of (2x - 9)² is (4x² - 36x + 81)
