[tex](a)\ y = 130x -350[/tex]

(b) y represents the price of the hotel

Step-by-step explanation:

Given

[tex]b = 130[/tex] --- slope

[tex]a = -350[/tex] --- y intercept

Solving (a): The equation of the regression line.

The general form of the equation of the regression line is:

[tex]y = bx + a\\[/tex]

Substitute values for b and a;

[tex]y = 130x + (-350)[/tex]

Remove bracket

[tex]y = 130x -350[/tex]

Solving (b): What y represents

From the question, we understand that: y stands for price

Hence, the symbol y represents the price of a hotel. The value of y  depends on x (the ratings)

Answer:

2496 cm sq.

Step-by-step explanation:

Length equals 52cm and Perimeter is 200cm.

Area = Length x Breadth (or Width).

To find the area we have to first find the breadth.

2 x (Length + Breadth) = Perimeter.

Substituting what's given in the question, we get:-

2 x ( 52 + Breadth) = 200

52 + Breadth = [tex]\frac{200}{2}[/tex]

52 + Breadth = 100

Breadth = 100 - 52

Breadth = 48cm.

So, Area equals-------->

Length x Breadth

= 52 x 48

Area = 2496 cm sq.

Answer:

Step-by-step explanation:

Number 5 is L because you have 18 coins but you only want to find the probability of the pennies. So take 3/18 and simplify to 1/6 by dividing both the numerator and the denominator by 3.

Number 6 can be (-6x - 3), just use the distributive property on the original expression.

Answer:

5. I.

6. -6x - 3

Step-by-step explanation:

For number five you add up all the coins, which equals 18. Secondly, you see how many pennies there are. There are 3 so the answer is 3/18. Then you simpy into 1/6.

For number six, you want to multiply 3 by -2x and then multiply 3 by -1. You will get the answer -6x -3. If you see a number outside the parenthesis then multiply by the number inside of it.

Answer:

A. 64%, B. 62%

Step-by-step explanation:

Find how many people do not have an email account.

168 + 24 = 192 Find the percentage.

192/300 = 0.64 Hence, 64% of shoppers don't have an email.

Do the same for B.

168 + 18 = 186

186/300 = 0.62

62% of shoppers don't have access to a computer.

The percentage of shopkeepers that don't have access to e-mail account are 64% and percentage of shop keepers with no computer access is 62%

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: percentage of the shoppers who don't have an e-mail account is 192 and percentage of the shoppers that don't have computer access are 186

Now total number of shopkeepers surveyed is 300

and thus percentage of shoppers do not have an e-mail account is

= 192/300 ×100

=64%

Again the total number of shopkeepers who do not have access of computer is = 186/300 × 100

                    =62%

Hence, The percentage of shopkeepers that don't have access to e-mail account are 64% and percentage of shop keepers with no computer access is 62%

Answer:

a. Nominal and qualitative.

b. Ratio and quantitative.

c. Interval and quantitative.

d. Interval and quantitative.

Step-by-step explanation:

A level of measurement can be defined as a classification which is used to illustrate the attributes of the values assigned to variables. There are four (4) basic levels of measurement for a variable and these are;

1. Interval: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.

2. Ratio: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.

3. Ordinal: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.

4. Nominal: is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.

In this scenario, the level of measurement and data type are listed below;

a. End-of-year stock classification (high yield, medium yield, or low yield): the level of measurement is nominal because they are categorized. Also, the type of data is qualitative because it describes the quality of the stock and it's non-numerical in nature.

b. Length (in feet) of a roll of plastic wrap advertised to be 30 feet long: the level of measurement is a ratio because they can be arranged in order. Also, it's a quantitative data because it is numerical in nature.

c. Temperature (in degrees Celsius): the level of measurement is an interval because they can be arranged in order and the difference in value is meaningful. Also, the type of data is quantitative because it is numerical in nature.

d. Duration (in minutes) of a call to a customer support line: the level of measurement is an interval because they can be arranged in order and the difference in value is meaningful. Also, the type of data is quantitative because it is numerical in nature.

Answer:

Answer:

0.0283642

Step-by-step explanation:

Number of uppercase letters = 26

Number of lowercas = 26 alphabets = 10

Number of password characters = 10

Hence total number of passwords with exactly 10 characters (26 + 26 + 10) ^10 = 62^10 = 839299365868340224 passwords

Password with 10 strings, and having atleast one upper, lower and digit character :

26^1 * 26^1 * 10^1 * (26+26+10)^7 = 23806114737966080 (1 upper, lower and digit character, the remaining 7 could be any of them)

Probability = required outcome / Total possible outcomes

P(password with atleast 1 upper, lower and digit character) = 23806114737966080 / 839299365868340224

= 0.0283642

Answer

Step-by-step explanation:

yes 20 feet long

The largest possible area for the play area would be 200 square feet when the width is 10 feet and the length is 20 feet. The smallest area she could have while using all 40 feet of fencing is 100 square feet.

To maximize the area of the play area, we can consider the dimensions that will allow for the largest possible rectangle. Let's denote the width of the play area as "w" (in feet) and the length as "l" (in feet).

Since one side of the play area is already taken care of by the house, we need to use the remaining 40 feet of fencing to enclose the other three sides.

We have two equal sides (width) and one side (length) that needs to be fenced.

Considering the given conditions:

The area needs to be at least 5 feet long and 5 feet wide.

The total length of the fencing is 40 feet.

Let's consider the possible scenarios:

Scenario 1: The width and length are both 5 feet.

In this case, the total length of the fencing required would be:

2 * 5 feet (width) + 5 feet (length) = 15 feet.

However, since we have 40 feet of fencing available, this scenario is not possible.

Scenario 2: The width is 10 feet, and the length is 20 feet.

In this case, the total length of the fencing required would be:

2 * 10 feet (width) + 20 feet (length) = 40 feet.

This scenario satisfies all the given conditions and uses all 40 feet of fencing. The area in this case would be:

Area = Width * Length = 10 feet * 20 feet = 200 square feet.

Therefore, the largest possible area for the play area would be 200 square feet when the width is 10 feet and the length is 20 feet.

As for the smallest area she could have while using all 40 feet of fencing, that would be when the play area is a square. Since all sides of a square are equal, the play area would be a square with sides of 10 feet each. The area in this case would be:

Area = Side * Side = 10 feet * 10 feet = 100 square feet.

So, the smallest area she could have while using all 40 feet of fencing is 100 square feet.

Answer:

The inverse of the function is [tex]f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}[/tex]

Step-by-step explanation:

Inverse of a function:

Suppose we have a function y = g(x). To find the inverse, we exchange the values of x and y, and then isolate y.

In this question:

[tex]y = \frac{x^3}{8} + 16[/tex]

Exchanging x and y:

[tex]x = \frac{y^3}{8} + 16[/tex]

[tex]\frac{y^3}{8} = x - 16[/tex]

[tex]y^3 = \frac{x-16}{8}[/tex]

[tex]y = \sqrt[3]{\frac{x-16}{8}}[/tex]

The inverse of the function is [tex]f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}[/tex]

Jena's large jewelry box is 132 inches³ bigger than her small cube jewelry box.

What is a cube?

A cube is a three dimensional figure. All of it's sides are equal in length and all the planes of it are perfect square.

Given, length of the each side of Jena's small jewelry box = 2 inches.

Therefore, the volume of the small jewelry box is = 2³ inches³ = 8 inches³.

Again, length of the each side of Jena's small jewelry box are 7 inches, 5 inches, and 4 inches.

Therefore, the volume of the small jewelry box is = (7 × 5 × 4) inches³ = 140 inches³.

Hence, the difference = (140 - 8) inches³ = 132 inches³.
