The example of systematic sampling is option c) in a population of 1000 at a school, every 64th person is chosen.

In systematic sampling, the population is first divided into a sampling frame (for example, a list or a map) and then every kth individual is selected from the list. In this example, every 64th person is chosen from the list of 1000 individuals, which is an example of systematic sampling. In the example given, there is a list of 1000 individuals, and every 64th person is chosen from the list. This means that the sampling interval k is 64, and the first individual is selected randomly from the first 64 individuals in the list. From then on, every 64th individual is selected to be included in the sample. For instance, if the first individual selected is number 8, then the individuals selected for the sample would be 8+64=72, 8+264=136, 8+364=200, and so on.

Different positive integers can be written in the eight empty circles so that the product if any three integers in a straight line is 3240 the largest possible sum of the eight surrounding numbers is approximately 117.59.

Since the product of any three integers in a straight line is 3240, we can write:

a * b * c = 3240

d * e * f = 3240

g * h * i = 3240

a * d * g = 3240

b * e * h = 3240

c * f * i = 3240

a * e * i = 3240

c * e * g = 3240

We can simplify these equations by taking the cube root of both sides:

abc = def = ghi = 30√6

adg = beh = cfi = 30√2

aei = cgi = 30

ceg = aei = 30

Now we can use these equations to solve for the eight surrounding integers. Without loss of generality, we can assume that a, b, and c are the three largest numbers. Then we have:

abc = 30√6

a > b > c

Since a, b, and c are positive integers, their product must have three prime factors. The prime factorization of 30√6 is 2^2 * 3 * 5 * √6. We can distribute the prime factors as follows:

a = 2 * 3 * 5 = 30

b = 2 * 3 * √6 ≈ 7.75

c = 5 * √6 ≈ 12.25

Since b and c are not integers, we need to swap them with d and e, which are integers. We can assume that d > e > f and solve for them using the equation def = 30√6:

d = 2 * 5 * √6 ≈ 17.32

e = 3 * 5 * √2 ≈ 10.61

f = √2 * √3 * √5 * √6 ≈ 3.87

Finally, we can use the remaining equations to solve for g, h, and i:

g = 2 * 5 * √2 ≈ 14.14

h = 3 * 5 * √6 ≈ 21.65

i = √2 * √3 * 5 ≈ 7.75

The sum of the eight surrounding numbers is therefore:

a + b + c + d + e + f + g + h + i = 30 + 12.25 + 17.32 + 10.61 + 3.87 + 14.14 + 21.65 + 7.75 ≈ 117.59

Therefore, the largest possible sum of the eight surrounding numbers is approximately 117.59.

a. Site A has the larger expected profit.

b. the expected profit for Site A is larger than Site B by $18 million

To find the expected profit for each site  we use the formula:

Expected Profit = (Probability of Finding Oil x Profit if Oil is Found) - (Probability of Not Finding Oil x Loss if No Oil is Found)

For Site A we have

Expected Profit = (0.2 x $110 million) - (0.8 x $17 million)

Expected Profit = $ 22 million - $ 13.6 million

Expected Profit = $8.4 million

For Site B

Expected Profit = (0.1 x $ 165 million) - (0.9 x $ 29 million)

Expected Profit = $16.5 million - $26.1 million

Expected Profit = -$9.6 million

b. The expected profit for Site A is $ 8.4 million and the expected profit for Site B is -$ 9.6 million.

The equation of the line is: y = 9.

To write the equation of a line in point-slope form, where (a, b) is a point on the line, and m is the slope, the equation can be expressed as:

y - b = m(x - a).

Given:

Two ponts on a line, (-4, 9) and (-1, 9)

Find the slope (m):

Slope of the line, m = change in y / change in x = (9 - 9)/(-4 -(-1))

Slope (m) = 0/-3 = 0

Substitute m = 0, and (a, b) = (-1, 9) into y - b = m(x - a):

y - 9 = 0(x - (-1))

y - 9 = 0(x + 1)

y - 9 = 0

The length of the base of the rectangle with an area of 21 m and height of 2 m is 10.5 meters.

A rectangle is a 2-dimensional shape with parallel opposite sides equal to each other and four angles are right angles.

Area of a rectangle is expressed as;

A = length × breadth

Given that the area of the rectangle is 21 square meters and the height is 2 meters, we can substitute these values into the formula and find the base length:

A = length × breadth

21 = length × 2

To solve for the length, we divide both sides of the equation by 2:

Length = 21 / 2

Length = 10.5 m

Therefore, the length of the rectangle is 10.5 m.

Answer:

m∠D = 94°

Step-by-step explanation:

Quadrilateral ABCD is also called a cyclic quadrilateral or a quadrilateral that is inscribed in a circle.

Opposite angles in a cyclic Quadrilateral are supplementary, i.e the sum of two opposite angles in a Quadrilateral = 180°

m∠A + m∠C = 180°

m∠A = 74°

74° + m∠C = 180°

m∠C = 180° - 74°

m∠C = 106°

In a cyclic quadrilateral, the total sum of the angles outside the circle = 360°

i.e =

m∠AB + m∠BC + mDC + mAD = 360°

m∠DAB= ( m∠C) × 2

= 106° × 2 = 212°

m∠DAB = m∠AD + m∠AB

m∠AD = 79°

212° = 79° + m∠AB

m∠AB = 212° - 79°

= 133°

m∠ABC = m∠AB + m∠BC

m∠AB = 133°

m∠BC= 55°

m∠ABC = 133° + 55°

= 188°

We are asked to find m∠D

m∠D = 1/2m∠ABC

m∠ABC = 188°

m∠D = 1/2 × 188°

m∠D = 94°

Therefore, m∠D = 94°

Based on the information given, the FICO score ranges from 300 to 850, with corresponding interest rates and total payments for an $8,000 principal balance.

To calculate how much more a household with a credit score of 580 will pay compared to a household with a credit score of 750, we need to determine the total amount paid for each credit score range and subtract the difference.

For a FICO score of 580, the total amount paid is $2,079 with an interest rate of 28% and 33 payments.

For a FICO score of 750, the total amount paid is $2,635 with an interest rate of 15% and 29 payments.

The difference in total amount paid between the two credit scores is:

$2,635 - $2,079 = $556

Therefore, a household with a credit score of 580 will pay $556 more than a household with a credit score of 750.

It is true that the indexed variables (members) of an array must be integers.

The indexed variables or members of an array must be integers. This is because arrays are data structures that store elements in a contiguous block of memory, and each element is accessed using an index. Indexing allows us to uniquely identify and retrieve specific elements within the array. In most programming languages, including C, C++, Java, and Python, array indices are integers and must be whole numbers (positive or negative) without any fractions or decimals. Attempting to use non-integer values as indices would result in a compilation error or unexpected behavior.

The base 10 representatiοn οf the number 1406 (3 at the bοttοm) is 118.

In mathematics, a base number refers tο the number system used tο represent numeric values. The base number determines the number οf symbοls used tο represent each value, as well as the value οf each symbοl. The mοst cοmmοn base number systems are base 10 (decimal), base 2 (binary), base 8 (οctal), and base 16 (hexadecimal).

In base 10, we use 10 digits (0-9) tο represent all pοssible values. In binary, we use οnly twο digits (0 and 1) tο represent values. In οctal, we use eight digits (0-7), and in hexadecimal, we use 16 digits (0-9 and A-F) tο represent values.

Fοr example, the decimal number 125 can be represented in base 2 as 1111101, in base 8 as 175, and in base 16 as 7D.

Cοnverting a number frοm οne base tο anοther invοlves dividing the number by the base and repeatedly finding the remainder until the quοtient becοmes zerο. The remainders, read frοm bοttοm tο tοp, represent the digits οf the new number in the new base.

Tο cοnvert a number in base 3 tο base 10, we need tο multiply each digit οf the number by the cοrrespοnding pοwer οf 3, and then sum up the prοducts.

Starting frοm the rightmοst digit οf the number, the pοwers οf 3 increase by 1 fοr each digit tο the left. Sο, fοr the number 1406 (3 at the bοttοm), we have:

1 × 3⁰ + 0 × 3¹ + 4 × 3² + 1 × 3³ = 1 + 0 + 36 + 81 = 118

Therefοre, the base 10 representatiοn οf the number 1406 (3 at the bοttοm) is 118.

The total surface area is 640.56 in².

We have,

The TSA (Total Surface Area) of a cone is given by the formula:

TSA = πr² + πrℓ

Now,

We see that,

There are two cones so we find the TSA for both the cones and add them up to get the TSA.

So,

Cone 1:

r = 6 in

l² = r² + h²

l² = 36 + 64

l² = 100

l = 10

So,

TSA = πr² + πrℓ

= 3.14 x 36 + 3.14 x 6 x 10

= 113.04 + 188.4

= 301.44 in²

Cone 2:

r = 6 in

l = 12 in

TSA = πr² + πrℓ

= 3.14 x 6 x 6 + 3.14 x 6 x 12

= 113.04 + 226.08

= 339.12 in²

Now,

Total surface area.

= 301.44 + 339.12

= 640.56 in²

Thus,

The relation "r" on the set of all integers, where x = y^2, is not reflexive.

A relation is reflexive if every element in the set is related to itself. In this case, for the relation x = y^2 to be reflexive, every integer "x" should be related to itself, meaning that x = x^2. However, this is not true for all integers.

For example, if we consider x = 2, it is not equal to 2^2 = 4. Similarly, if we consider x = -3, it is not equal to (-3)^2 = 9.

Since there are integers that do not satisfy the condition x = x^2, the relation x = y^2 is not reflexive on the set of all integers.
