Henry needs to buy the 9.96 bags of grass seed to cover the lawn area:

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. It is a two-dimensional figure. The area of the shape on the paper is referred to as its Area. Consider your square to be made up of smaller unit squares.

Geometrical shapes are two-dimensional shapes and closed figures such as circles, squares, rectangles, rhombuses, and so on. The three-dimensional shapes in solid geometry are the cube, cuboid, cone, sphere, and cylinder. All of these shapes can be found in various forms all over the place.

The length of the lawn L = 128.

the width of the lawn B = 72.

bag of grass seed covers an area of 925 ft².

He anticipates that he will require 8 bags of grass seed.

Now first we find the area of the lawn:

area of lawn = L x B

                    = 128 * 72

                    = 9,216 ft²

The grass seed required to covers an area of lawn = 9,216 ft²

one bag of grass seed covers an area of 925 ft².

= 9216/925

= 9.96

The friend has to save for 5 and 2/3 of a month to in order to make up the remaining 85 to get the 125 headphone.

An inequality that consists of two or more parts is called a compound inequality. Either "or" or "and" may be used in these components. A number between 5 and 10 could be used as x in an inequality, for instance, if it states that "x is larger than 5 and less than 10". Any time one of the two inequalities is true when the two inequalities are united by the word or, the compound inequality is solved. The two separate solutions have been combined to form the final answer. Inequalities that are separated by "and" or "or" form a compound inequality. The intersection of the inequality graphs is shown by the graph of a compound inequality with a "and."

Cost of the headphone 125.

What the friend have: 40.

What need to save: 125-40 = 85

Let x = amount to be saved per month

Months to save up the 85 is 15

The equation would be 15 x = 85

Therefore x = 85/15

Which is 5 2/3 months.

It is concluded that the null hypothesis H0 is rejected. Therefore, there is enough evidence to claim that some of the population proportions differ from those stated in the null hypothesis, at the α=0.05 significance level.

(1) Null and Alternative Hypotheses

The following null and alternative hypotheses need to be tested:

H0: P1 = \(9/16,P_2-3/16, P_3-3/16,P_4-1/16\)

Some of the population proportions differ from the values stated in the null hypothesis

This corresponds to a Chi-Square test for Goodness of Fit.

(2) Test Statistics

The Chi-Squared statistic is computed as follows:

\(4.356 + 0 + 11.267 + 0.2 = 15.822\)

(3) Decision about the null hypothesis

Since it is observed that χ2=15.822>χc2​=7.815, it is then concluded that the null hypothesis is rejected.

(4) Conclusion

It is concluded that the null hypothesis H0 is rejected. Therefore, there is enough evidence to claim that some of the population proportions differ from those stated in the null hypothesis, at the α=0.05 significance level.

The proportion of all novels that are between 50,000 and 60,000 words is approximately 0.

A. The random variable X, representing the number of words in a randomly selected romance novel, follows a normal distribution with a mean (μ) of 64,182 and a standard deviation (σ) of 17,154.

B. To find the proportion of all novels that are between 50,000 and 60,000 words, we need to calculate the area under the normal curve between those two values.

First, we need to standardize the values using the z-score formula:

z₁ = (50,000 - μ) / σ

z₂ = (60,000 - μ) / σ

Substituting the given values:

z₁ = (50,000 - 64,182) / 17,154

z₂ = (60,000 - 64,182) / 17,154

Calculating these z-scores will give us the standardized values.

Next, we need to find the corresponding cumulative probabilities for each z-score using a standard normal distribution table or a statistical calculator.

Let's assume we find P(Z < z1) = P(Z < z2) = p.

The proportion of all novels between 50,000 and 60,000 words is given by:

Proportion = P(z1 < Z < z2)

= P(Z < z2) - P(Z < z1)

= p - p

= 0

Since the probabilities are the same, the proportion of novels between 50,000 and 60,000 words is approximately 0.

Among the provided functions, the ones that approach positive infinity as x approaches negative infinity are:

- f(x) = 2x^5

- f(x) = 6x^8 + 9x^6 + 32

- f(x) = -x + 8x^4 + 248

To determine which functions approach positive infinity as x approaches negative infinity, we need to analyze the leading terms of the functions. The leading term dominates the behavior of the function as x becomes very large or very small.

Let's examine each function and identify their leading terms:

1. f(x) = 2x^5

The leading term is 2x^5, which has a positive coefficient and the highest power of x.

As x approaches negative infinity, this term becomes very large and positive, indicating that f(x) approaches positive infinity.

2. f(x) = 9x + 100

The leading term is 9x, which has a positive coefficient but a lower power of x compared to the constant term 100.

As x approaches negative infinity, the leading term becomes very large and negative, indicating that f(x) approaches negative infinity, not positive infinity.

3. f(x) = 6x^8 + 9x^6 + 32

The leading term is 6x^8, which has a positive coefficient and the highest power of x.

As x approaches negative infinity, this term becomes very large and positive, indicating that f(x) approaches positive infinity.

4. f(x) = -8x^3 + 11

The leading term is -8x^3, which has a negative coefficient and the highest power of x.

As x approaches negative infinity, this term becomes very large and negative, indicating that f(x) approaches negative infinity, not positive infinity.

5. f(x) = -10x + 5x + 26

Combining like terms, we have f(x) = -5x + 26.

The leading term is -5x, which has a negative coefficient but a lower power of x compared to the constant term 26.

As x approaches negative infinity, the leading term becomes very large and positive, indicating that f(x) approaches negative infinity, not positive infinity.

6. f(x) = -x + 8x^4 + 248

The leading term is 8x^4, which has a positive coefficient and the highest power of x.

As x approaches negative infinity, this term becomes very large and positive, indicating that f(x) approaches positive infinity.

Therefore, the correct choices are:

- f(x) = 2x^5

- f(x) = 6x^8 + 9x^6 + 32

- f(x) = -x + 8x^4 + 248

2r^2+6r+5r+15=0

2r(r+3)+5(r+3)=0

(r+3)(2r+5)=0

Answer:

r = - 3, r = - \(\frac{5}{2}\)

Step-by-step explanation:

Given

2r² + 11r + 15 = 0

Consider the factors of the product of the coefficient of the r² term and the constant term which sum to give the coefficient of the r- term.

product = 2 × 15 = 30 and sum = 11

The factors are + 6 and + 5

Use these factors to split the r- term

2r² + 6r + 5r + 15 = 0 ( factor the first/second and third/fourth terms )

2r(r + 3) + 5(r + 3) = 0 ← factor out (r + 3) from each term

(r + 3)(2r + 5) = 0

Equate each factor to zero and solve for r

r + 3 = 0 ⇒ r = - 3

2r + 5 = 0 ⇒ 2r = - 5 ⇒ r = - \(\frac{5}{2}\)

What is least squares regression line?

The line that best matches a linear connection between two variables in data is called a least-squares regression line because it minimizes the vertical distance between the data points and the regression line.

The given equation is,

y = 0.6p + 10.0

The residual for the day when 520 people attended was 35.

So, p = 520.

Plug 520 in the above equation, we get

y = 0.6(520) + 10.0

y = 312 + 10

y = 322

As, people attended was 35

So,

y = 322 + 35

y = 357

Answer:

\(x\leq 76\)

Step-by-step explanation:

Let x = unknown number

⇒ \(\frac{8}{9}*(x-4)\leq 64\)

⇒ \(\frac{8(x-4)}{9} \leq 64\)

Multiply both sides by 9:

⇒ \(8(x-4)\leq 576\)

Expand brackets:

⇒ \(8x-32\leq 576\)

Add 32 to both sides:

⇒ \(8x\leq 608\)

Divide both sides by 8:

⇒ \(x\leq 76\)

The rule that must be used to find out the number of ways that two representatives can be picked, where one is a mathematics major and the other is a computer science major, is the product rule.

The product rule is a fundamental principle in combinatorics that states that if there are m ways to perform one task and n ways to perform another task, then there are m * n ways to perform both tasks together. In this case, we can consider the selection of a mathematics major representative as one task and the selection of a computer science major representative as another task.

To apply the product rule, we need to determine the number of ways each task can be performed. Let's say there are k mathematics majors and j computer science majors available. To select one mathematics major representative, we have k choices, and for the computer science major representative, we have j choices. Therefore, according to the product rule, the total number of ways to pick one mathematics major and one computer science major representative is k * j.

Answer:

slope is 10x

Y - intercept is 7

Step-by-step explanation:

The equation of the line whose slope is 10 and passes through the point (0, 7) is y = 10x + 7

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have a line that has a slope of 10 and passes through the point (0, 7).

Assume the equation of the line to be -

y = 10x + c            {since m = 10}

For the point (0, 7), we can write -

7 = 10 x 0 + c

c = 7

So, the equation of the line will be -

y = 10x + 7

Therefore, the equation of the line whose slope is 10 and passes through the point (0, 7) is y = 10x + 7
