7.071 is the length, in inches, of each side of the square.

What is meant by "square"?

The term "square" refers to a regular quadrilateral having four equal-length sides and angles. Angles in the square are at right angles or are separated by 90 degrees. The diagonals of the square are also equal and meet at a 90-degree angle.

                             Having equal length sides and right angles on all four, a square is a quadrilateral. Due to the fact that a square's sides are all the same length, it may be distinguished from other types of rectangles. Every square consequently becomes a rectangle since it is a quadrilateral with right angles at all four of its angles.

If the side od=f a square is s, the diagonal is  s√2

  This comes from Pythagoras as diagonal is

   √s² + s²  = √2s² = s√2

 as such s√2 = 10

           s = 10/√2

        = 10 * √2/√2  * √2

         = 5√2

    5 * 1.4142  = 7.071

The length from point A to point B on the clock is approximately 24.083 cm, which is closest to 24 cm. This is calculated using the Pythagorean theorem.

Using the Pythagorean theorem, we can calculate the length from point A to point B as follows

First, we need to find the length of the vertical line segment from point D to point A. This is equal to the radius of the clock, which is 24 cm.

Next, we can find the length of the horizontal line segment from point D to point B. This is equal to the distance from the top of the clock at point D to the hanger at point B, which is given as 2 cm.

Now, we can use the Pythagorean theorem to find the length from point A to point B

AB² = AD² + DB²

AB² = (24 cm)² + (2 cm)²

AB² = 576 cm² + 4 cm²

AB² = 580 cm²

AB ≈ 24.083 cm

Therefore, the length from point A to point B is approximately 24.083 cm, which is closest to 24 cm.

The variance of the area of the circle is [tex]\pi^2\theta^{4/45}[/tex].

The mean area of the circle is [tex]\pi\theta^{2/3}.[/tex]

Let X be the radius of the circle, uniformly distributed on [0, θ].

The probability density function of X is given by:

[tex]f(x) = 1/\theta, for 0 \leq x \leq θ[/tex]

= 0, otherwise

Let Y be the area of the circle. Then[tex]Y = \pi X^2.[/tex] We want to find the mean and variance of Y.

Mean of Y:

By the law of the unconscious statistician, the mean of Y is given by:

[tex]E(Y) = E(\pi X^2) = \pi E(X^2)[/tex]

[tex]E(X^2)[/tex] using the formula for the variance of X:

[tex]Var(X) = E(X^2) - [E(X)]^2[/tex]

Since X is uniformly distributed on [0, θ], we have:

[tex]E(X) = (0 + \theta)/2 = \theta/2[/tex]

[tex]Var(X) = [(\theta - 0)^2]/12 = \theta^{2/12}[/tex]

Solving for [tex]E(X^2)[/tex], we get:

[tex]E(X^2) = Var(X) + [E(X)]^2 = \theta^2/12 + (\theta/2)^2 = \theta^{2/3}[/tex]

Substituting this into the expression for E(Y), we get:

[tex]E(Y) = \pi E(X^2) = \pi (\theta ^{2/3}) = \pi \theta^{2/3}[/tex]

Variance of Y:

To find the variance of Y, we can use the formula for the variance of a function of a random variable:

[tex]Var(Y) = E(Y^2) - [E(Y)]^2[/tex]

We can find[tex]E(Y^2)[/tex] using the law of the unconscious statistician:

[tex]E(Y^2) = E[(\pi X^2)^2] = \pi^2E(X^4)[/tex]

To find [tex]E(X^4)[/tex], we can use the formula for the fourth moment of a uniform distribution:

[tex]E(X^4) = (\theta^4 + 2\theta^2)/5[/tex]

Substituting this into the expression for[tex]E(Y^2)[/tex], we get:

[tex]E(Y^2) = \pi^2E(X^4) = \pi^2[(\theta^4 + 2\theta^2)/5] = \pi^2\theta^{4/5} + 2\pi^2\theta^{2/5}[/tex]

Substituting this and the expression for E(Y) into the formula for the variance of Y, we get:

[tex]Var(Y) = E(Y^2) - [E(Y)]^2[/tex]

[tex]= \pi^2\theta^{4/5} + 2\pi^2\theta^{2/5} - (\pi\theta^2/3)^2[/tex]

If Cara's calculation of the sum of the squared differences i.e. 1370 from the mean is incorrect, that would be the first error she made in computing the variance.

As the steps for finding the variance are not provided, it is difficult to determine the first error Cara made.

However, the formula for calculating the variance is:

Variance = (sum of the squared differences from the mean) / (number of observations)

The first error Cara may have made is in calculating the sum of the squared differences from the mean.

The correct steps to find the variance are:

Find the mean:

Mean = (87 + 46 + 90 + 78 + 89) / 5 = 78

Calculate the differences from the mean for each observation:

87 - 78 = 9

46 - 78 = -32

90 - 78 = 12

78 - 78 = 0

89 - 78 = 11

Square each difference:

[tex]9^2 = 81[/tex]

[tex](-32)^2 = 1024[/tex]

[tex]12^2 = 144[/tex]

[tex]0^2 = 0[/tex]

[tex]11^2 = 121[/tex]

Find the sum of the squared differences:

81 + 1024 + 144 + 0 + 121 = 1370

Divide the sum of squared differences by the number of observations:

Variance = 1370 / 5 = 274.

Therefore, the statement "The sample mean absolute deviation is likely to be higher for the samples with lower satisfaction rates" would be the BEST description of the MAD for this data set.

To calculate the mean absolute deviation (MAD), we first need to find the mean of each sample.

Sample 1:[tex]17/25 = 0.68[/tex]

Sample 2: [tex]12/25 = 0.48[/tex]

Sample 3: [tex]14/25 = 0.56[/tex]

Sample 4: [tex]9/25 = 0.36[/tex]

Next, we calculate the deviation of each observation from its respective sample mean:

Sample 1: |0.68 - x1|, |0.68 - x2|, ..., |0.68 - x25|

Sample 2: |0.48 - x1|, |0.48 - x2|, ..., |0.48 - x25|

Sample 3: |0.56 - x1|, |0.56 - x2|, ..., |0.56 - x25|

Sample 4: |0.36 - x1|, |0.36 - x2|, ..., |0.36 - x25|

where xi is the satisfaction rating (0 or 1) of the Ith customer in the sample.

The MAD is the average of these deviations:

MAD = (|0.68 - x1| + |0.68 - x2| + ... + |0.36 - x25|)/100

Since we don't know the actual ratings of the customers, we cannot calculate the MAD exactly. However, we can say that the MAD is likely to be higher for samples 2 and 4, which have lower satisfaction rates, compared to samples 1 and 3, which have higher satisfaction rates. Therefore, the statement "The sample mean absolute deviation is likely to be higher for the samples with lower satisfaction rates" would be the BEST description of the MAD for this data set.

A. The number of 7-card stud poker hands is 133,784,560 and the number of 7-card stud poker hands is 674,274,182,400.

B. The number of hands of 7-draw poker that contain the ace of hearts is 18,009,460.

C. The probability that a 7-card draw hand contains the ace of hearts is 0.135.

a) The number of 7-card draw poker hands can be calculated using the combination formula, which is:

[tex]^{n} C_{r}[/tex] = n! / (r! * (n - r)!)

where n is the total number of cards in the deck (52) and r is the number of cards in each hand (7).

So, the number of 7-card draw poker hands is:

[tex]^{52} C_{7}[/tex] = 52! / (7! * (52 - 7)!)

= 133,784,560.

The number of 7-card stud poker hands can be calculated using the permutation formula, which is:

[tex]^{n} P_{r}[/tex] = n! / (n - r)!

where n is the total number of cards in the deck (52) and r is the number of cards in each hand (7).

So, the number of 7-card stud poker hands is:

[tex]^{52} P_{7}[/tex] = 52! / (52 - 7)!

= 674,274,182,400.

b) To count the number of hands of 7-draw poker that contain the ace of hearts, we can treat the ace of hearts as a special card that must be included in each hand. Then, we need to choose the remaining 6 cards from the 51 cards that are not the ace of hearts.

So, the number of hands of 7-draw poker that contain the ace of hearts is:

[tex]^{51} C_{6}[/tex] = 51! / (6! * (51 - 6)!)

= 18,009,460.

c) To calculate the probability that a 7-card draw hand contains the ace of hearts, we can use the formula:

P(event) = number of favourable outcomes / total number of possible outcomes

The total number of possible 7-card draw hands is 133,784,560, which we calculated in part (a).

The number of favourable outcomes is the number of hands of 7-draw poker that contain the ace of hearts, which we calculated in part (b).

So, the probability that a 7-card draw hand contains the ace of hearts is:

P(ace of hearts) = 18,009,460 / 133,784,560 ≈ 0.135

The required probability is 0.135.

The exponential function of the form y=ab^x that has the given points is y = (25/7)(7/5)^x

We can use the given points to set up a system of equations and solve for the values of a and b in the exponential function y = ab^x.

Using the point (1,5), we get:

5 = ab^1

Using the point (2,7), we get:

7 = ab^2

Now, we can solve for a and b by dividing the second equation by the first:

7/5 = (ab^2)/(ab^1

Simplifying this expression, we get:

7/5 = b

Substituting this value of b back into one of the original equations, we can solve for a:

5 = a(b^1) = a(b) = a(7/5)

Answer: 5.966 feet

Step-by-step explanation: To find the depth of the river in 1848, we can start by calculating the depth of the river in 1847 after the 16% drop.

16% of 6.7 feet is 0.16 x 6.7 = 1.072 feet.

So the depth of the river in 1847 was 6.7 - 1.072 = 5.628 feet.

Next, we can calculate the depth of the river in 1848 after the 6% rise.

6% of 5.628 feet is 0.06 x 5.628 = 0.338 feet.

So the depth of the river in 1848 was 5.628 + 0.338 = 5.966 feet.

Therefore, the depth of the river in 1848 was approximately 5.966 feet.

a) 160 cans are needed to make 5 pounds of aluminum

b) There are 32 cans per pound of aluminum.

To determine how many cans are needed to make 5 pounds of aluminum, we need to use the given information that 8 empty cans make 1/4 pound of aluminum. We can set up a proportion to solve for the number of cans needed:

8 cans : 1/4 lb = x cans : 5 lbs

To solve for x, we can cross-multiply and simplify

8 cans × 5 lbs = 40 cans

1/4 lb × x cans = 5 lbs

x cans = 5 lbs / (1/4 lb) = 20 lbs

Therefore, 20 × 8 = 160 cans are needed to make 5 pounds of aluminum.

To find out how many cans are there per pound of aluminum, we can use the inverse of the given information:

8 cans : 1/4 lb = 32 cans : 1 lb

So, there are 32 cans per pound of aluminum.

So, there are 36 such subsets.

Number of non-empty subsets s of[tex]{1, 2, 3, . . . , 8}[/tex] such that the product of the elements of s is at most 200, we can use a method called inclusion-exclusion principle.
First, we need to count the total number of non-empty subsets of the given set.

Since each element can either be included or excluded, there are [tex]2^8 - 1 = 255[/tex] non-empty subsets.
Next, we need to count the number of subsets whose product is greater than 200.

We can start by considering the subsets that contain 8, since 8 is the largest element in the set.

There are only two such subsets: {8} and {1, 8}.

Both of these subsets have a product greater than 200. Similarly, we can consider subsets that contain 7, and so on. We find that there are[tex]2^7 - 1 = 127[/tex] subsets that contain 7, and each of these subsets has a product greater than 200. Similarly, there are [tex]2^6 - 1 = 63[/tex] subsets that contain 6, and each of these subsets has a product greater than 200.
Double-counted the subsets that contain both 6 and 7, as well as those that contain both 6 and 8, and those that contain both 7 and 8.

Subtract the number of subsets that contain both 6 and 7, both 6 and 8, and both 7 and 8.

There are [tex]2^5 - 1 = 31[/tex] subsets that contain both 6 and 7, and each of these subsets has a product greater than 200.

Similarly, there are[tex]2^5 - 1 = 31[/tex] subsets that contain both 6 and 8, and each of these subsets has a product greater than 200.

Finally, there are [tex]2^5 - 1 = 31[/tex] subsets that contain both 7 and 8, and each of these subsets has a product greater than 200.
However, we have subtracted too much, since we have now excluded subsets that contain all three of 6, 7, and 8. There are only two such subsets: {6, 7, 8} and {1, 6, 7, 8}. Both of these subsets have a product greater than 200.

The probability that exactly 5 of Pete's friends will pass the CPA exam is approximately 0.275

This problem can be solved using the binomial distribution. We know that the probability of passing the CPA exam for a graduate of Pete's College of Business is p = 0.71.

We also know that there are eight friends taking the exam, so the number of trials (n) is 8. We want to find the probability that exactly 5 of them will pass.

The formula for the probability mass function of the binomial distribution is

P(X = k) = (n choose k) × p^k × (1-p)^(n-k)

where X is the random variable representing the number of successes (i.e., the number of Pete's friends who pass), k is the number of successes we want to find (i.e., 5), (n choose k) is the binomial coefficient, which represents the number of ways to choose k successes out of n trials, and p is the probability of success (i.e., 0.71).

Plugging in the numbers, we get

P(X = 5) = (8 choose 5) × 0.71⁵ × (1-0.71)³

= 56 × 0.71 × 0.29³

1) Approximately 68% of the x values fall within the range of the mean plus or minus one standard deviation.

2) Nearly 95% of the x values fall within the range of the mean plus or minus two standard deviations.

3) Nearly 99.7% of the x values fall within a range of 3 standard deviations either above or below the mean.

Considering the data provided:

mean = 71 inches

Standard deviation = 2.5 inches

We want to know where 95% of the x values fall. The variation from the mean is 2 standard deviations. Therefore,

2 standard deviations = 2 × 2.5 = 5 inches

Heights:

71 - 5 = 66 inches and

71 + 5 = 76 inches

Therefore, the range of heights between 66 inches and 76 inches indicates the center 95% of males' heights from this school.

In an all-boys school, the heights of the student body are normally distributed with a mean of 71 inches and a standard deviation of 2.5 inches. Using the empirical rule, determine the interval of heights that represents the middle 95% of male heights from this school.

This is possible if the first twin was born just before midnight and the second twin was born just after midnight, on different calendar days.

For the most part, twins and multiples share the same birthday. However, depending on the time of day the babies are born and how long the timespan is between each baby's birth, twins can be born on different days.

Twins are defined as two offspring born together, but that doesn't necessarily mean they are born on the same date. Multiples are generally born only a few minutes apart. If delivered by cesarian section, the interval between births is usually only a minute, maybe two.

The aircraft carrier's average speed was 120 mph.

I'm sorry, but I cannot provide a definitive answer to your question as I do not have access to the table you are referring to.

However, in general, to find the price per spool of each kind of thread, you would need to know the total price of the package and the number of spools in the package.

To calculate the price per spool, you would divide the total price of the package by the number of spools in the package. For example, if a package costs $10 and contains 50 spools of thread, the price per spool would be $0.20 ($10 ÷ 50 = $0.20).

You can use this method to find the price per spool for each type of thread in the table you are looking at.

We can use the formula for inverse variation, which states that the product of the time and the speed is constant:

time × speed = constant

Let's use t to represent the time needed to travel the distance at 54 miles per hour. We know that the time is 10 hours when the speed is 24 miles per hour. So we can set up the equation:

10 × 24 = t × 54

Simplifying, we get:

240 = 54t

Dividing both sides by 54, we get:

t = 240/54

Simplifying this fraction, we get:

t = 40/9

So it will take approximately 4.44 hours, or 4 hours and 26 minutes, to travel the same distance at 54 miles per hour.

As a result, the geometric sequence's sixth term, which has a ratio of 2/3 and a first term of 2, is 32/243.

A mathematical series known as a geometric sequence is one in which each term following the first is obtained by multiplying the previous term by a constant, non-zero quantity known as the common ratio2. To put it another way, it is a sequence in which each term (aside from the initial term) is multiplied by a fixed amount to obtain the subsequent term1.

For instance, the geometric sequence 1, 2, 4, 8, 16,... has a common ratio of 2, since each item after the first is derived by multiplying the previous term by 2.

Aₙ = a₁× r(n-1) is the formula for the nth term of a geometric series, where a1 is the first term and r is the common ratio.

The common ratio in this instance is 2/3, and the first term is 2.

As a result, the sequence's nth term is represented by the formula

a = 2 × (2/3)(n-1).

We change n = 6 in the formula to get the sixth term in the sequence.

A₆ = 2× (2/3)⁵

= 2 × (2/3)⁵ = 32/243 as a result.

As a result, the geometric sequence's sixth term, which has a ratio of 2/3 and a first term of 2, is 32/243.
