This scatter plot shows the relationship between the number of sweatshirts sold and the temperature outside

Step-by-step explanation:

The numbers between the squares are the possible answers.

For example, 2/3 ÷ 3/4 is either 1/2 or 8/9.

2/3 ÷ 3/4

2/3 × 4/3

8/9

The answer is 8/9, so you'll move up to the next square.

The length of each side of each plot is 40 meters. Given that the area of 10 square plots is 160 ares. The area of 1 plot = 160 / 10 = 16 ares.

Given that the area of 10 square plots is 160 ares. The area of 1 plot = 160 / 10 = 16 ares

1 ares = 100 square meters

1 plot = 16 ares = 16 x 100 = 1600 square meters

Let the side of each square plot be a m

Side of 1 square plot = length of 1 square plot = breadth of 1 square plot = a m

Area of 1 square plot = a × a = a² sq.m

According to the given problem, the area of 1 square plot is 1600 square meters

So, a² = 1600 square meters

Taking the square root on both sides, a = √1600 m = 40 m

Thus, the length of each side of each plot is 40 meters.

Given the function:

Let's find the function after differentiating it 68 times.

To differentiate, let's take the derivative.

First derivative:

Second derivative:

Since 3 is the constant with respect to x, the derivative of 3cos(3x) with respect to x will be:

After the second differentiation, we have -sin, , the same will be applicable to the 68th time.

Therefore, for the 68th differentiation the exponent for the constant -3 will be 68.

Therefore, after differentiating the function 68 times, we have:

Answer:

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that m describes based on its sign and value:

A line is increasing, and goes upwards from left to right when m > 0

A line is decreasing, and goes downwards from left to right when m < 0

A line has a constant slope, and is horizontal when m = 0

A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.

Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:

m =

y2 - y1

x2 - x1

Answer:

Part A: 7.8

Part B: Square Root Of 62

Step-by-step explanation:

Part A: 7.8 is a rational number because it can be expressed as a fraction or 78/10.

Part B: The square root of 62 is irrational because it cannot be expressed as a fraction.

Please mark me Brainliest!

Answer:

Part A: 7.8. It equals 78/10.

Part B: √61. It is about 7.8102

Step-by-step explanation:

Part A:

Yes, you are correct. I'm going to expand on your answer, however.

So, recall what rational numbers are. They are any number that cannot be written as a fraction between two integers. Another way of saying this is that if the number doesn't repeat and doesn't terminate, then it's irrational.

So, yes, 7.8 is a rational number between 7.7 and 7.9.

In fact, there are infinite rational numbers between 7.7 and 7.9. 7.8 is rational. So is 7.88. And 7.888. And 7.8888. Their fractions are, respectively: 78/10, 788/100, 7888/1000, and 78888/10000. They can all be written as a fraction (between two integers), and so, they are rational.

Part B:

So, unlike rational numbers, irrational numbers do not terminate and they do not repeat. An example is √2. Its approximation is 1.41424...  This doesn't repeat nor terminate.

To find an irrational number between 7.7 and 7.9, the strategy is to square the two numbers. 7.7^2 is 59.29 and 7.9^2 is 62.41. Now, we just need to find a number within this range that when you take the square root of it, it is irrational.

After thinking, 61 is a valid candidate. The square root of 61 is 7.81024... It doesn't repeat and doesn't terminate. It is irrational.

In fact, the square root of any prime number is irrational.

And 7.81024... is between 7.7 and 7.9. Therefore, an answer we could give is √61.

And it's approximately 7.8102.

The matrix representing the relation r^4 is m^4, where m is the matrix representing relation r.

To find the matrix representing the relation r^4, we need to perform matrix multiplication of the matrix m four times. Let's denote the matrix representing the relation r as m. To calculate r^4, we multiply m by itself four times, i.e., m^4.

Each multiplication represents the composition of the relation with itself. We perform matrix multiplication of m with itself, then multiply the resulting matrix by m again, and repeat this process for a total of four times. The final result is the matrix m^4, which represents the relation r^4.

The equation of the line that has a slope of -7/3, has an x intercept at (-9,0) passes through the point (6,-35) is y = (-7/3)x - 21

An equation is an expression that shows the relationship between two or more numbers and variables.

The standard equation of a straight line is:

Ax + By = C

Where A, B and C are constants

The slope intercept form is:

y = mx + b

Where m is the rate of change and b is the y intercept

Given that the line has a slope of -7/3 has an x intercept at (-9,0) passes through the point (6,-35). Using the slope and y intercept:

y - y₁ = m(x - x₁)

y - 0 = (-7/3)(x - (-9))

y = (-7/3)x - 21

The equation of the line is y = (-7/3)x - 21

Logistic regression models the probability of a binary outcome, while CART models segment data into categories. For example, CART is preferable when data has complex interactions, as it can partition data into multiple categories.

Logistic regression and classification and regression trees (CART) are two different machine learning models used for binary classification problems. Logistic regression models the probability of one class or the other based on a linear combination of input variables. This makes it useful for predicting a binary outcome, such as whether a customer will purchase a product or not. On the other hand, CART is a decision tree model that divides data into categories. It uses a tree-like structure to split the data into segments based on the input features. This makes it useful for dealing with data with complex interactions, as it can partition data into multiple categories. For example, a CART model would be preferable to a logistic regression model if there are multiple underlying factors that affect the binary outcome. In this case, a CART model could more accurately identify the categories that are associated with a particular outcome. Overall, CART models are superior for dealing with data with complex interactions, whereas logistic regression is better for simpler data.

The scientific notation is a way of representing numbers that are either too large, or too small.

The scientific notation of the population is: \(\mathbf{Population = 2.1 \times 10^7}\)

The population is given as:

\(\mathbf{Population = 20612439}\)

Multiply the population by 1

\(\mathbf{Population = 20612439 \times 1}\)

Express 1 as\(\mathbf{\frac{10000000}{10000000}}\)

So, we have:

\(\mathbf{Population = 20612439 \times \frac{10000000}{10000000}}\)

Rewrite as:

\(\mathbf{Population = \frac{20612439}{10000000} \times 10000000}\)

Divide

\(\mathbf{Population = 2.0612439 \times 10000000}\)

Express 10000000 as an exponent of base 10

\(\mathbf{Population = 2.0612439 \times 10^7}\)

Approximate the decimal to the nearest tenth

\(\mathbf{Population = 2.1 \times 10^7}\)
