Answer:

4, 2.75, 1.5, 0.25, - 1, - 2.25, ...............

Step-by-step explanation:

Using the recursive formula with f(1) = 4, then

f(2) = f(1) - 1.25 = 4 - 1.25 = 2.75

f(3) = f(2) - 1.25 = 2.75 - 1.25 = 1.5

f(4) = f(3) - 1.25 = 1.5 - 1.25 = 0.25

f(5) = f(4) - 1.25 = 0.25 - 1.25 = - 1

f(6) = f(5) - 1.25 = - 1 - 1.25 = - 2.25

Sequence is 4, 2.75, 1.5, 0.25, - 1, - 2.25, .......

The number of ounces above which 86% of the dispensed sodas will fall is 7.8 ounces. This can be answered by the concept of Standard deviation.

To find the number of ounces above which 86% of the dispensed sodas will fall, we need to find the z-score corresponding to the 86th percentile.

Using a standard normal distribution table or calculator, we can find that the z-score corresponding to the 86th percentile is approximately 1.08.

We can then use the formula:

z = (x - μ) / σ

where z is the z-score, x is the value we want to find, μ is the mean, and σ is the standard deviation.

Plugging in the values we know:

1.08 = (x - 12.4) / 4.3

Solving for x, we get:

x = 7.8

Therefore, the number of ounces above which 86% of the dispensed sodas will fall is 7.8 ounces.

The third term of the sequence is 11.

The sequence given by the rule

f(1) = 5

and

f(n) = f(n-1) + 3, for n bigger than 1.

The third term of the sequence can be calculated using the given formula of the sequence.

We are given that

f(1) = 5, which means that the first term of the sequence is 5.

We can find the second term of the sequence using the formula.

f(n) = f(n-1) + 3

Now n = 2

    f(2)  = f(2-1) + 3

           = f(1) + 3

           = 5 + 3

            = 8

Therefore, the second term of the sequence is 8.

Using the same formula we can find the third term of the sequence

f(n) = f(n-1) + 3

Now n = 3

f(3) = f(3-1) + 3

     = f(2) + 3

     = 8 + 3

      = 11

Therefore, the third term of the sequence is 11. Hence, the correct answer is 11.

When selecting a random sample of people to survey, Julio should consider a few important elements. Firstly, he should ensure that his sample is representative of the population he is trying to study. This means that he should try to include a diverse range of people from different ages, genders, socioeconomic backgrounds, and so on.

Additionally, he should consider the size of his sample, as larger samples generally provide more accurate results. Finally, he should strive for a random sample, where each person in the population has an equal chance of being selected, to avoid bias and ensure that his results are generalizable to the larger population. In summary, when selecting a random sample for his survey, Julio should consider factors such as representativeness, sample size, and randomness to ensure accurate and reliable results.


1. Representativeness: Ensure the sample accurately represents the population he's studying, covering various demographics such as age, gender, and socioeconomic status.

2. Sample Size: Choose an appropriate sample size (e.g., 100 people) to ensure the survey results are statistically significant and minimize sampling error.

3. Randomization: Use a random selection method, like a random number generator or drawing names from a hat, to ensure each individual has an equal chance of being chosen.

4. Avoid Bias: Make sure the selection process is free from personal or external influence, so the sample remains truly random and unbiased.

Answer:

D. x > -3 and x < 1

Step-by-step explanation:

There is an absolute value in this inequality, so we have to solve for 2 instances -- where the quantity in the absolute value is positive, and where it is negative.

First, we will isolate the absolute value by dividing by 3:

3|x + 1| < 6

|x + 1| < 2

Then, because this is a less-than case of the absolute value, we can put it in between the positive and negative absolute values of the other side:

-|2| < x + 1 < |2|

-2 < x + 1 < 2

and solve.

-3 < x < 1

(this can also be written as x > -3 and x < 1)

2.25 liters of solution in all is there in the test tubes. So, the correct option is 2.25 l.

The total volume of solution in the 15 test tubes can be calculated by multiplying the volume of one test tube by the number of test tubes:

Total volume = 15 test tubes × 150 milliliters/test tube

Total volume = 2,250 milliliters

However, the question asks for the answer in liters, so we need to convert milliliters to liters by dividing by 1,000:

Total volume = 2,250 milliliters ÷ 1,000

Total volume = 2.25 liters

Therefore, there are 2.25 liters of solution in all the test tubes.

According to given information, the length of the rectangular storage unit is 12 feet.

What is rectangle?

A rectangle is a two-dimensional shape with four sides and four right angles. It is a quadrilateral with opposite sides that are parallel and equal in length.

We can use the Pythagorean theorem to find the length of the storage unit. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the 5-foot-wide floor and the length of the storage unit form the two sides of a right triangle, with the diagonal (the distance from one corner to the opposite corner) being the hypotenuse. We can set up the equation as:

\(hypotenuse^2 = side1^2 + side2^2\)

where side1 = 5 feet and hypotenuse = 13 feet.

Simplifying this equation, we get:

\(hypotenuse^2\)\(= 5^2 + side2^2\)

169 = 25 + \(side2^2\)

\(side2^2\) = 144

side2 = 12

Therefore, the length of the storage unit is 12 feet.

In the electron configuration of an atom, each electron is described by a set of four quantum numbers, which includes the principal quantum number (n), the angular momentum quantum number (l), the magnetic quantum number (m), and the spin quantum number (s). The second quantum number (l) determines the shape of the subshell, which in turn influences the energy level and chemical behavior of the atom. The letter designation for each subshell is based on the value of the angular momentum quantum number (l): s (l=0), p (l=1), d (l=2), f (l=3), and so on.

Answer:

Step-by-step explanation:

LM = 18

LN = 27

MN = LN - LM

MN = 27 - 18

MN = 9

Here are the vectors **t**, **n**, and **b** at the given point:

* **t** = (-3 sin t, 3 cos t, 0)

* **n** = (-3 cos t, -3 sin t, 3 / cos^2 t)

* **b** = (3 cos^2 t, -3 sin^2 t, -3)

The vector **t** is the unit tangent vector, which points in the direction of the curve at the given point. The vector **n** is the unit normal vector, which points in the direction perpendicular to the curve at the given point. The vector **b** is the binormal vector, which points in the direction that is perpendicular to both **t** and **n**.

To find the vectors **t**, **n**, and **b**, we can use the following formulas:

```

t(t) = r'(t) / |r'(t)|

n(t) = (t(t) x r(t)) / |t(t) x r(t)|

b(t) = t(t) x n(t)

```

In this case, we have:

```

r(t) = (3 cos t, 3 sin t, 3 ln cos t)

r'(t) = (-3 sin t, 3 cos t, 3 / cos^2 t)

```

Substituting these into the formulas above, we can find the vectors **t**, **n**, and **b** as shown.

The vectors **t**, **n**, and **b** are all orthogonal to each other at the given point. This is because the curve is a smooth curve, and the vectors are defined in such a way that they are always orthogonal to each other.

The binormal vector (b) is perpendicular to both the tangent and normal vectors and completes the orthogonal coordinate system.

To find the vectors t, n, and b at the given point, we need to calculate the first derivative, second derivative, and third derivative of the position vector r(t).
Given r(t) = (3 cos t, 3 sin t, 3 ln cos t), we can calculate the derivatives as follows:
First derivative:
r'(t) = (-3 sin t, 3 cos t, -3 sin t / cos t)
Second derivative:
r''(t) = (-3 cos t, -3 sin t, -3 cos t / cos^2 t + 3 sin^2 t / cos t)
       = (-3 cos t, -3 sin t, -3 cos t / cos^2 t + 3 tan^2 t)
Third derivative:
r'''(t) = (3 sin t, -3 cos t, 6 cos t / cos^3 t - 6 sin t / cos t)
        = (3 sin t, -3 cos t, 6 sec^3 t - 6 tan t sec t)
At the given point (3, 0, 0), substitute t = 0 into the derivatives to find the vectors:
r'(0) = (0, 3, 0)
r''(0) = (-3, 0, 3)
r'''(0) = (0, -3, 6)
Therefore, at the given point, the vectors t, n, and b are:
t = r'(0) = (0, 3, 0)
n = r''(0) = (-3, 0, 3)
b = r'''(0) = (0, -3, 6)
These vectors represent the tangent, normal, and binormal vectors, respectively, at the given point.
The tangent vector (t) represents the direction of motion of the curve at that point. The normal vector (n) is perpendicular to the tangent vector and points towards the center of curvature.

The binormal vector (b) is perpendicular to both the tangent and normal vectors and completes the orthogonal coordinate system.

An engineer is interested in the effects of cutting speed (A), tool geometry (B), and cutting angle (C) on the life (in hours) of a machine tool. Two levels of each are chosen, and three replicates of a 2323 factorial design are run.

The chosen terms, effect, and factorial can be defined as follows:

Terms: A - Cutting Speed B - Tool Geometry C - Cutting Angle Effect :In experimental design, the term "effect" refers to the difference in the outcome caused by a change in the treatment, given that other possible sources of variation are accounted for and controlled. Therefore, a factor's effect refers to the variation in the response variable (life of the machine tool) that is linked to changes in the factor level.

Factorial: The factorial experiment is a statistical experiment in which many variables are studied at once to determine the influence of each of these variables on the response variable. In a factorial experiment, the effect of each factor and the effect of each combination of factors are investigated.

The results of the experiment are shown in the following table:

Sum of treatment combinations = $$\sum y_{ij}=22+31+25+32+43+29+35+34+50+55+47+46+44+45+38+40+37+36+60+50+54+39+41+47=869$$

Grand mean:

$$\bar{y}_{...} = \frac{1}{N} \sum_{i=1}^r \sum_{j=1}^k y_{ij} = \frac{1}{8\cdot 3} \cdot 869 = 36.21$$

Sum of squares for each treatment:

$\text{SS}_A=3\cdot [(32.75-36.21)^2+(48.5-36.21)^2]=79.0450$$\text{SS}_B=3\cdot [(38.25-36.21)^2+(41.5-36.21)^2]=10.5234$$\text{SS}_C=3\cdot [(42.75-36.21)^2+(40.5-36.21)^2]=23.9822$$

Total sum of squares:

$\text{SST}=\sum_{i=1}^r\sum_{j=1}^k(y_{ij}-\bar{y}_{...})^2=1557.75$

The sums of squares of treatments (SST) were calculated using the following formula:

$$\text{SST} = \sum_{i=1}^{r} \frac{(\sum_{j=1}^{k} y_{ij})^2}{k} - \frac{(\sum_{i=1}^{r} \sum_{j=1}^{k} y_{ij})^2}{Nk}$$

The sums of squares of errors (SSE) were calculated using the following formula:$$\text{SSE} = \text{SST} - \text{SS}_A - \text{SS}_B - \text{SS}_C$$

The degrees of freedom are $df_T = Nk-1 = 23$, $df_E = N(k-1) = 16$, and $df_A = df_B = df_C = k-1 = 2$.

$$MS_A=\frac{\text{SS}_A}{df_A}=\frac{79.0450}{2}=39.5225$$

$$MS_B=\frac{\text{SS}_B}{df_B}=\frac{10.5234}{2}=5.2617$$$$MS_C=\frac{\text{SS}_C}{df_C}=\frac{23.9822}{2}=11.9911$$

$$F_A=\frac{MS_A}{MS_E}=\frac{39.5225}{\frac{107.9063}{16}}=5.77$$$$F_B=\frac{MS_B}{MS_E}=\frac{5.2617}{\frac{107.9063}{16}}=0.94$$

$$F_C=\frac{MS_C}{MS_E}=\frac{11.9911}{\frac{107.9063}{16}}=1.63$$

The $p$-value for $F_A$ with 2 and 16 degrees of freedom can be found using an $F$-distribution table or calculator. We can use an online calculator to find that the $p$-value for $F_A$ is approximately 0.015.

The $p$-value for $F_B$ with 2 and 16 degrees of freedom can be found using an $F$-distribution table or calculator. We can use an online calculator to find that the $p$-value for $F_B$ is approximately 0.401.

The $p$-value for $F_C$ with 2 and 16 degrees of freedom can be found using an $F$-distribution table or calculator. We can use an online calculator to find that the $p$-value for $F_C$ is approximately 0.223.
