1. Balance or scale with appropriate precision: To measure approximately 1.00 g of sodium hydroxide within a 10% margin of error, it is important to use a balance or scale that provides sufficient precision. A balance or scale with a precision of at least 0.1 g would be suitable for this purpose. Such a device would allow measurements to be made with an accuracy of 0.1 g, ensuring that the measurement of 1.00 g of sodium hydroxide falls within the desired 10% margin of error.

2. Measurement procedure: To accurately measure approximately 1.00 g of sodium hydroxide, follow these steps:

- Place a clean and dry weighing boat or container on the balance or scale.

- Tare the balance or scale to zero to subtract the weight of the weighing boat.

- Carefully add sodium hydroxide to the weighing boat until the displayed weight reaches approximately 1.00 g.

- Make small adjustments, adding or removing sodium hydroxide, to achieve the desired weight as closely as possible.

- Once the weight is stable and close to 1.00 g, record the measurement.

By using a balance or scale with an appropriate precision and following a careful measurement procedure, it is possible to accurately measure approximately 1.00 g of sodium hydroxide within a 10% margin of error.

Using the Binomial probability distribution,

The probability that exactly two customers in the sample will default on their payments is 0.31..

We have given that,

4% of total customers a mortgage company default on their payments .

The probability of success i.e number of customers default on their payments (p) = 4%

= 0.04

The probability of failure (q) = 1-p = 1-0.04 = 0.06

Total number of customers in sample (n) = 20

we have to find out the probability that exactly two customers in the sample will default on their payments.

Using the Binomial probability distribution,

P(X=x)= ⁿCₓ(p)ˣ(q)⁽ⁿ⁻ˣ⁾

the required probability is P(X= 2 )

Now, P(X= 2) = ²⁰C₂(0.04)²(0.06)¹⁸

No, the plan will not work because tan B = 8/5; B ≈ 58°

There are three primary trigonometric ratios for a right angle triangle and they are:

sin x = opposite/hypotenuse

cos x = adjacent/hypotenuse

tan x = opposite/adjacent

To get angle B, we will make use of trigonometric ratios to get:

tan B = 8/5

tan B = 1.6

B = tan⁻¹1.6

B = 58°

From the ramp, we can see that the angle is greater than what Gael wants to build and as such we can say it will not work.

Answer:

see explanation

Step-by-step explanation:

(a)

given y is inversely proportional to x³ then the equation relating them is

y = \(\frac{k}{x^3}\) ← k is the constant of proportion

to find k use any of the ordered pairs from the table

using (1, 8 ) , then

8 = \(\frac{k}{1^3}\) = \(\frac{k}{1}\) ⇒ k = 8

y = \(\frac{8}{x^3}\) ← equation of proportion

(b)

when y = 64 , then

64 = \(\frac{8}{x^3}\) ( multiply both sides by x³ )

64x³ = 8 ( divide both sides by 64 )

x³ = \(\frac{8}{64}\) = \(\frac{1}{8}\) ( take cube root of both sides )

x = \(\sqrt[3]{\frac{1}{8} }\) = \(\frac{1}{2}\)

If the alternative hypothesis states that the population mean (μ) is not equal to $12,000, the rejection region for the hypothesis test would be both tails.

This means that we reject the null hypothesis if the sample mean falls in either the left tail or the right tail of the sampling distribution.

In a two-tailed test, we are interested in detecting differences in both directions from the hypothesized value. We want to determine if the population mean is significantly different from $12,000, whether it is greater than or less than $12,000.

To conduct the hypothesis test, we set up the null hypothesis (H₀) as μ = $12,000, and the alternative hypothesis (H₁) as μ ≠ $12,000. The rejection region is determined based on the significance level (α) chosen for the test.

If the test is conducted at a significance level of α, we divide the significance level equally between the two tails of the sampling distribution. For example, if α = 0.05, each tail would have an area of 0.025, resulting in a rejection region in both tails.

When we calculate the test statistic and compare it to the critical value(s) from the appropriate distribution, we reject the null hypothesis if the test statistic falls in either tail of the distribution.

Therefore, the correct answer is C) Both tails.

The dimensions of the box that maximize the volume are x = √700 and h = 100 / √700.

To find the largest possible volume of the box, we need to optimize the dimensions of the box. Let's denote the length of each side of the square base as x and the height of the box as h.

The surface area of the box consists of the area of the square base (x^2) and the four sides of the box (4xh). Since the box has an open top, we do not consider the top surface. The total surface area is given as 2100 square centimeters, so we have:

x^2 + 4xh = 2100

To maximize the volume, we need to express the volume of the box (V) in terms of a single variable. The volume of a rectangular prism is given by V = x^2h.

We can rewrite the equation for the surface area to solve for h:

h = (2100 - x^2) / (4x)

Now we can substitute this expression for h in the volume equation:

V = x^2 * [(2100 - x^2) / (4x)]

Simplifying, we have:

V = (1/4) * (2100x - x^3)

To find the maximum volume, we need to find the critical points of this function. We take the derivative of V with respect to x and set it equal to zero:

dV/dx = 2100/4 - (3/4)x^2 = 0

Solving this equation, we find:

2100/4 = (3/4)x^2

x^2 = 700

x = √700

Substituting this value back into the equation for h, we find:

h = (2100 - 700) / (4 * √700) = 1400 / (4 * √700) = 100 / √700

Therefore, the largest possible volume of the box is:

V = (1/4) * (2100 * √700 - 700 * √700) = 350√700 cubic centimeters.

To solve the system of equations using Gaussian elimination, we can represent the system in augmented matrix form and perform row operations to transform it into row echelon form (REF) and then into reduced row echelon form (RREF).

The augmented matrix for the given system is:

\(\left[\begin{array}{ccccc}1&3&1&1& |3\\2&-2&1&2 &|8\\3&1&2&-1&|-1\end{array}\right]\)

Performing row operations to transform the matrix into REF:

R2 = R2 - 2R1

R3 = R3 - 3R1

\(\left[\begin{array}{ccccc}1&3&1&1& |3\\0&-8&-1&0 &|2\\0&-8&-1&-4&|-10\end{array}\right]\)

Now, perform row operations to further simplify the matrix:

R3 = R3 - R2

\(\left[\begin{array}{ccccc}1&3&1&1& |3\\0&-8&-1&0 &|2\\0&-8&-1&-4&|-12\end{array}\right]\)

The matrix is now in REF. Now, let's transform it into RREF:

R2 = (-1/8)R2

R3 = (-1/4)R3

\(\left[\begin{array}{ccccc}1&3&1&1& |3\\0&1&1/8&0 &|-1/4\\0&0&0&1&|3\end{array}\right]\)

Now, perform row operations to further simplify the matrix:

R1 = R1 - R2 - R4

R2 = R2 + (1/8)R4

\(\left[\begin{array}{ccccc}1&3&1&1& |3\\0&1&1/8&0 &|-1/4\\0&0&0&1&|3\end{array}\right]\)

Finally, perform row operations to obtain the RREF:

R1 = R1 - 3R2

\(\left[\begin{array}{ccccc}1&0&-5/8&0& |7/4\\0&1&1/8&0 &|-1/4\\0&0&0&1&|3\end{array}\right]\)

Using proportions, the coordinates of point G are given as follows:

(1.8, 1.6).

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The points A and B are given as follows:

A(-3, 4) and B(5,0).

For this problem, we have that the ratio of AG to GB is 3:2, hence:

AG = 3/5AB

G - A = 3/5(B - A).

The x-coordinate of G is found as follows:

x + 3 = 3/5(5 + 3)

x + 3 = 4.8

x = 1.8.

The y-coordinate of G is found as follows:

y - 4 = 3/5(0 - 4)

If the scale of drawing is 1 inches : 250 inche and the real horse height is 15 inche, then the height of the horse in drawing is 0.06 inches.

The ratio that describes the relationship between the true figure itself and model is called the scale. It serves as a representation of the real statistics in smaller units on maps. A scale of 1:5, for instance, indicates that 1 on the map is approximately the size of 5 in the actual world.

The scale of drawing the horse = 1 inch :

Therefore in scale

Horse height in drawing equals one inch

The  height of the horse = 250 inche

The original height of the horse = 15 inche

The height in the picture = x inches

To find the height the horse in the picture, we have to use proportion

1 inch : 250 inche = x inches : 15 inche

1 / 250 = x / 15

1 × 15= 250x

250x = 15

x = 15/250

x = 0.06 inches

Therefore, the height of the horse in drawing is 0.06 inches

the length of the actual kitchen wall is 144 inches.

The ratio used to depict the relationship between the dimensions of a model or scaled figure and the corresponding dimensions of the real figure or object is called the scale. On the other hand, a scale factor is a value that is used to multiply all of an object's parts in order to produce an expanded or decreased figure.

Given, On a scale drawing, a kitchen wall is 6 inches long. The scale factor is 1/24

If the scale factor is 1/24, it means that every 1 inch on the drawing represents 24 inches in real life.

Let's set up a proportion:

1 inch on the drawing : 24 inches in real life = 6 inches on the drawing : x inches in real life

where x is the length of the actual wall.

To solve for x, we can cross-multiply:

1 inch on the drawing * x inches in real life = 6 inches on the drawing * 24 inches in real life

x = 6 inches on the drawing * 24 inches in real life / 1 inch on the drawing

x = 144 inches in real life
