1. 45 dollars per year.

2. 49.73 dollars per year.

3. 56.6 dollars per year.

4. Increases

Step-by-step explanation:

Average rate of change

The average rate of change of a function \(f(x)\) over an interval [a,b] is given by:

\(A = \frac{f(b)-f(a)}{b-a}\)

In this question, we have that:

\(A(t) = 900(1.05)^t\)

1. What is the average rate of change for the first year?

\(A(0) = 900(1.05)^0 = 900\)

\(A(1) = 900(1.05)^1 = 945\)

So

\(A = \frac{A(1)-A(0)}{1-0} = \frac{945-900}{1-0} = 45\)

45 dollars per year.

2. What is the average rate of change for the first five years?

\(A(0) = 900(1.05)^0 = 900\)

\(A(5) = 900(1.05)^5 = 1148.65\)

\(A = \frac{A(5)-A(0)}{5-0} = \frac{1148.65-900}{5-0} = 49.73\)

49.73 dollars per year.

3. What is the average rate of change for the first ten years?

\(A(0) = 900(1.05)^0 = 900\)

\(A(10) = 900(1.05)^{10} = 1466\)

\(A = \frac{A(10)-A(0)}{10-0} = \frac{1466-900}{10-0} = 56.6\)

56.6 dollars per year.

4. Does the average rate of change increase or decrease as time from the initial deposit gets longer?

From the previous items, it increases.

Using probability the correct option is B)The probability that p is in the interval is equal to the level of confidence for the interval.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty. For pupils in Class 10, probability is a crucial subject because it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.

The probability that p is in the interval is equal to the level of confidence for the interval.

Reason -

There is a 95% probability that the interval between X [lower bound] and Y [upper bound] contains the true value of the population parameter. The statement above is the most common misconception about confidence interval. After the statistical interval is calculated, the interval can only either contain the population parameter or not.

Hence the correct option is B) The probability that p is in the interval is equal to the level of confidence for the interval.

Answer:

B. (1 ± sqrt(33)) / 4

Step-by-step explanation:

the 2 solutions for a quadratic equation

ax² + bx + c = 0

are defined as

x = (-b ± sqrt(b² - 4ac)) / 2a

in our example here we have

a = -2

b = 1

c = 4

=>

x = (-1 ± sqrt(1 + 32)) / -4 = (1 ± sqrt(33)) / 4

as we can easily divide top and bottom by -1 to turn the -1 and -4 into positive numbers, and the second top part, the square root, is a ± factor anyway. just withing the sign dues not change the fact that is is still a ± factor (both signs apply).

and now it is clear, it has to be option B.

the others disqualify because they have either no division by any form of 4, or the "1" and the "4" have different signs. but our equation shows they need to have equal signs (either both negative or both positive).

Answer:

a. A data set with ​14, ​68, and s41.

Step-by-step explanation:

For a normally distributed data set; Q₁ and Q₃ will be 0.6745 × 2 = 1.349 standard deviation.

The interquartile range IQR = Q₃ -  Q₁ = 1.349 × \({\sigma}\)

              Q₁        Q₃          \({\sigma}\)         IQR = Q₃ -  Q₁             1.349 × \({\sigma}\)

a.            14        68          41               = 68 - 14              1.349 × 41

                                                            = 54                   = 55.309

b.         1330      2940      2440         = 2940 - 1330      1.349 × 2440

                                                           = 1610                  = 3291.56

c.         2.2         7.3          2.1            = 7.3 - 2.2             1.349 × 2.1

                                                           = 5.1                   = 2.8329

d.         105        270          33           = 270 - 105          1.349  × 33

                                                          = 165                   = 44.517

From the above calculation, we will see that option a have a data set that is approximately normal.

The correct option on Hash 1 and Hash 2 is C. Hash 1 is designed to work with small input data, while Hash 2 is optimized for processing large input data.

The main difference between Hash 1 and Hash 2 is the amount of input data they can process. Hash 1 can process input data that is 2 characters long, while Hash 2 can handle input data that is up to 300,000 characters long. This means that Hash 2 is better suited for processing larger datasets than Hash 1.

In terms of which hash function is better suited for different types of data, it depends on the specific application and the characteristics of the data being processed. For example, if the data being hashed is small and of low complexity, Hash 1 may be a good choice due to its speed and simplicity.

The unit rate of computers per day using the graph is that 12 computers are made per day.

The unit rate is how many units of quantity correspond to the single unit of another quantity. We say that when the denominator in rate is 1, it is called unit rate. Unit rates is said to be the amount of something in each unit or per unit.

To obtain the unit rate of computers sold per day using the graph, we need to obtain the slope of the graph, which is the change in y per change in x

So, it is given by:

\(\text{Slope} = \dfrac{\text{change in y}}{\text{change in x}}\)

\(\text{Slope} = \dfrac{\text{y}_2-\text{y}_1}{\text{x}_2-\text{x}_1}\)

\(\text{y}_2 = 60 , \ \text{y}_1 = 36 , \ \text{x}_2 = 5, \ \text{x}_1 = 3.\)

\(\text{Slope} = \dfrac{(60 - 36)}{(5 - 3)} = \dfrac{24}{2} = 12\)

Given statement solution is :- a) The area of one semi-circle at one end is  58.09 square feet.

b) The area of the garden is 274.42 square feet.

c) The area in square metres is approximately 58.09 square feet.

The area of the garden is approximately 274.42 square feet, and the area in square meters is approximately 25.49 square meters.

a) To find the area of one semi-circle at one end, we need to calculate the area of a complete circle and then divide it by 2. The formula for the area of a circle is A = πr², where A represents the area and r is the radius.

Since the diameter of the semi-circle is equal to the width of the rectangular portion, which is 8.6 feet, the radius will be half of that, which is 8.6 / 2 = 4.3 feet.

Now we can calculate the area of the semi-circle:

A = (π * 4.3²) / 2

A ≈ 58.09 square feet

b) To find the area of the garden, we need to sum the area of the rectangular portion with the areas of the two semi-circles.

Area of the rectangular portion = length * width

Area of the rectangular portion = 18.4 feet * 8.6 feet

Area of the rectangular portion ≈ 158.24 square feet

Area of the two semi-circles = 2 * (area of one semi-circle)

Area of the two semi-circles ≈ 2 * 58.09 square feet

Area of the two semi-circles ≈ 116.18 square feet

Total area of the garden = area of the rectangular portion + area of the two semi-circles

Total area of the garden ≈ 158.24 square feet + 116.18 square feet

Total area of the garden ≈ 274.42 square feet

c) To convert the area from square feet to square meters, we need to know the conversion factor. Since 1 foot is approximately 0.3048 meters, we can use this conversion factor to convert the area.

Area in square meters = Total area of the garden * (0.3048)²

Area in square meters ≈ 274.42 square feet * 0.3048²

Area in square meters ≈ 25.49 square meters

Therefore, the area of one semi-circle at one end is approximately 58.09 square feet. The area of the garden is approximately 274.42 square feet, and the area in square meters is approximately 25.49 square meters.

To find:

The number that can be multiplied by the second equation to eliminate the x-variable when the equations are added together.

Solution:

We have,

\(x-3y=9\)                        ...(i)

\(\dfrac{1}{5}x-2y=-1\)       ...(ii)

The coefficient of x in (i) and (ii) are 1 and \(\dfrac{1}{5}\) respectively.

To eliminate the variable x by adding the equations, we need the coefficients of x as the additive inverse of each other, i.e, a and -a So, a+(-a)=0.

It means, we have to convert \(\dfrac{1}{5}\) into -1. It is possible if we multiply the equation (ii) by -5.

On multiplying equation (ii) by -5, we get

\(-x+10y=5\)       ...(iii)

On adding (i) and (iii), we get

\(7y=14\)

Here, x is eliminated.

Therefore, the number -5 can be multiplied by the second equation to eliminate the x-variable.

If each value is equally likely and the mean of x is 6, x = 24.

We're given a set of {0, 1, 2, 3, x} where x is unknown and the mean of x is 6. In order to find the value of x, we can plug all the known values in the formula first and then we're going to simplify the equation:
