Step-by-step explanation:

To find the class limits for the lowest class, you need to know the class interval, which is the difference between the upper class limit and the lower class limit of each class1. You can find the class interval by subtracting the first two class midpoints: 72.5 - 69.5 = 3.

Then, you can find the lower class limit of the lowest class by subtracting half of the class interval from the first class midpoint: 69.5 - 1.5 = 68.

Similarly, you can find the upper class limit of the lowest class by adding half of the class interval to the first class midpoint: 69.5 + 1.5 = 71.

Therefore, the class limits for the lowest class are 68 and 71.

  1280/2187

Step-by-step explanation:

We usually study arithmetic and geometric sequences. The terms of an arithmetic sequence have a common difference. The terms of a geometric sequence have a common ratio. You can tell what kind of a sequence it is by determining if the difference is constant of the ratio is constant.

__

Here, the difference of the first two terms is 10 -15 = -5. The next term of an arithmetic sequence would be 10 +(-5) = 5. The next term is not that, but is 20/3.

The ratio of the first two terms is 10/15 = 2/3. If the sequence is geometric, the next term will be 10(2/3) = 20/3, which it is. This geometric sequence has first term 15 and common ratio 2/3.

__

The general term of a geometric sequence is ...

  \(a_n=a_1\cdot r^{n-1}\qquad\text{$n^{th}$ term with first term $a_1$ and common ratio $r$}\)

You want the 9th term of the given sequence. It is ...

  \(a_9=15\cdot\left(\dfrac{2}{3}\right)^{9-1}=5\cdot 2^8\cdot3^{-7}\\\\\boxed{a_9=\dfrac{1280}{2187}}\)

The big-O estimate for the number of operations in this segment of the algorithm is O(n), where n represents the input size.

To give a big-O estimate for the number of operations used in a segment of an algorithm, we need more specific information about the segment and its complexity. Big-O notation provides an upper bound on the growth rate of the algorithm as the input size increases.

If the segment involves a loop that iterates n times, and each iteration performs a constant number of operations (additions or multiplications), then the complexity would be O(n). This means that the number of operations increases linearly with the input size.

However, without further details about the specific segment or the algorithm's overall structure, it is challenging to provide a more accurate estimation. The complexity analysis requires examining the code's control flow and considering factors such as nested loops or recursion.

In summary, the big-O estimate for the number of operations in this segment of the algorithm is O(n), where n represents the input size.

Answer:

Let x be the first unknown angle, and y be the second unknown angle.

We know that the sum of the three angles in a triangle is 180 degrees, so:

85 + 9kx + 10kx = 180

where k is a constant representing the ratio of the other two angles.

Simplifying the equation, we get:

19kx = 95

Dividing both sides by 19k, we get:

x = 5/k

Since the ratio of the other two angles is 9:10, we know that:

y = 9kx = 9k(5/k) = 45

So the measures of the two unknown angles are:

x = 5/k and y = 45

We cannot find the exact measures of x and y without more information, but we know that x and y are in a ratio of 9:10 and their sum is 180 - 85 = 95 degrees. We can set up the following equation to solve for k:

5/k + 45/k = 95

50/k = 95

k = 50/95

Using this value of k, we can find the measures of x and y:

x = 5/k = 5/(50/95) = 9.5

y = 9kx = 9(50/95)(9.5) = 47.37

Therefore, the measures of the two unknown angles are x = 9.5 degrees and y = 47.37 degrees (rounded to two decimal places).

A ladder is resting against a wall.The top of the ladder touches the wall at a height of 9 feet.Find the length of the ladder if the length is 3 feet more than its distance from the wall.

Let the distance of the ladder from the wall be x

The length of the ladder = x+3

The ladder touches the wall at a vertical height of 9 feet.

(x+3)^2 = x^2 + 9^2 ( using the pythagoras theorem

x^2 + 6x+ 9 = x^2 + 81

x^2- x^2 +6x = 81-9

6x= 72

Step-by-step explanation:

In the geometric model of the problem, the guy wire is the hypotenuse of a right triangle, with the tower being one leg, and the distance along the ground from the tower being the other leg. The ground distance is "adjacent" to the angle of elevation, so the relevant trig function is ...

  Cos = Adjacent/Hypotenuse

Solving for the hypotenuse, gives ...

  hypotenuse = adjacent/cos(α) = (34 ft)/cos(55°) ≈ 59 ft

The length of the guy wire is about 59 feet.

The account balance grows by approximately $5548.78 for each additional year within the given time period.  We need to find the difference in the balance over that time period and divide it by the difference in time.

The formula for the balance in the investment account after t years is given by 9500(1.062^t). Let's calculate the average rate of change:

Balance at t = 5.5 years:

B(5.5) = 9500(1.062^5.5)

Balance at t = 3.5 years:

B(3.5) = 9500(1.062^3.5)

Average rate of change = (B(5.5) - B(3.5)) / (5.5 - 3.5)

Now, let's compute the values:

B(5.5) ≈ 9500(1.062^5.5) ≈ 9500(1.434714)

B(3.5) ≈ 9500(1.062^3.5) ≈ 9500(1.206178)

Average rate of change ≈ (9500(1.434714) - 9500(1.206178)) / (5.5 - 3.5)

Finally, we can calculate the approximate average rate of change:

Average rate of change ≈ (13653.78 - 11458.69) / 2

Average rate of change ≈ 11097.55 / 2

Average rate of change ≈ 5548.78

Interpreting the result, from 3.5 to 5.5 years after the account is opened, the balance of the account increases at an average rate of $5548.78 per year. This means that, on average, the account balance grows by approximately $5548.78 for each additional year within the given time period.

standard deviation, σ = 1.3 of the normal distribution and we need to find how much time must be spent on leisure activities by an adult living in household with no young children to be in the group of adults who spent the highest 3% of the time in a day in such activities

. Let x be the amount of time that should be spent on leisure activities by an adult to be in the group of adults who spent the highest 3% of the time in a day in such activities. Now, we know that the highest 3% of the

time in a day in such activities will correspond to the area to the right of z value of 0.97. Hence, we can write the z score as: 0.97 = (x - µ) / σz = (x - 4.5) / 1.3x - 4.5 = 0.97 × 1.3x = 6.011Therefore, an adult living in household with no young children must spend 6.011 hours on leisure activities to be in the group of adults who spent the highest 3% of the time in a day in such activities

An adult living in a household with no young children must spend approximately 6.95 hours on leisure activities to be in the group of adults who spent the highest 3% of time in a day on such activities.

To find the amount of time an adult must spend on leisure activities to be in the highest 3%, we need to use the z-score formula and find the corresponding value.

First, we calculate the z-score using the formula:

z = (x - μ) / σ

where x is the value we want to find, μ is the mean (4.5 hours), and σ is the standard deviation (1.3 hours).

Next, we find the z-score corresponding to the highest 3% by subtracting 3% from 100% (97%). Using a z-table or a calculator, we find that the z-score corresponding to 97% is approximately 1.8808.

Now, we can solve for x:

1.8808 = (x - 4.5) / 1.3

Multiply both sides by 1.3:

1.8808 * 1.3 = x - 4.5

2.44504 + 4.5 = x
