[tex]A = 10[/tex] × [tex]7 + 6[/tex] × [tex]7 + 6[/tex] × [tex]5[/tex]

[tex]A = 70 + 6[/tex] × [tex]7 +6[/tex] × [tex]5[/tex]

[tex]A = 70 + 42 +6[/tex] × [tex]5[/tex]

[tex]A = 112 + 6[/tex] × [tex]5[/tex]

[tex]A = 112 +30[/tex]

[tex]A = 142[/tex]

Therefore, the surface area of a rectangular prism is [tex]142 m ^2[/tex].

Answer:

2

Step-by-step explanation:

The scale factor represented her is 2.  You are going from 1 to 2, so multiply by two.

You are also going from 1.25 to 2.5, so multiply this by 2 as well.

A scale factor tells us how many time greater a measurement gets.

The correct answer is B) distribution.

A statistical distribution refers to the collection of data points that provide information about how a particular variable is spread or distributed across different values.

In other words, it describes the frequency or likelihood of each possible outcome or observation within a dataset.

Understanding the distribution of data is essential in statistics because it helps us analyze and make predictions about various phenomena. Common types of distributions include the normal distribution, uniform distribution, and exponential distribution, among others.

Statistical distributions are characterized by their center (average or median), shape (how the data is spread out), and spread (how much variation exists within the data).

These three aspects collectively provide valuable insights into the data's overall behavior and are fundamental for statistical analysis and decision-making.

Therefore, when we talk about the collection of data points that answer a statistical question, we are referring to the distribution of the data, which encapsulates important information about its characteristics.

Answer:

6.9824 rounded to the nearest tenth is 6.9. But i am pretty sure the correct answer is 7

Step-by-step explanation:

6.9824 rounded to the nearest tenth is 6.99.

To round 6.9824 to the nearest tenth, we look at the hundredth place, which is 8 in this case. Since 8 is greater than or equal to 5, we round the digit in the tenth place up by 1.

So, rounding 6.9824 to the nearest tenth:

1. Identify the hundredth place: 8

2. Since 8 is greater than or equal to 5, we round the digit in the tenth place up by 1.

3. The digit in the tenth place is 9.

4. The number becomes 6.99.

Complete correct question:

Round 6.9824 to the nearest tenth.

Answer:

area = 3.14

Step-by-step explanation:

A = pi * r^2

The radius of this circle is 1.

So pi * 1^2

= pi * 1

in this case it says to use 3.14 as pi

so 3.14 * 1 = 3.14

The tangents of the acute angles in a right triangle can be calculated by taking the ratio of the side opposite the angle to the side adjacent to the angle.

In a right triangle, the tangent of an acute angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. Let's say the acute angles of the right triangle are A and B, and the sides opposite to them are denoted as A and b, respectively. Then, the tangents of the angles A and B can be calculated as:

Tan(A) = a/b

Tan(B) = b/a

Step-by-step explanation:

Given:

Charges of one hour swimming class = $5

Maximum amount that parents are willing to spend for swimming = $100

To find: inequality representing the possible number of hours, a student could take swimming lessons

Solution:

An inequality compares two values such that either one value is less than, greater than, or not equal to another value.

Let x represents number of hours spend by a student in swimming class.

As maximum amount that parents are willing to spend for swimming is $100 and charges of one hour swimming class is $5,

[tex]5x\leq 100\\x\leq \frac{100}{5} =20\\x\leq 20[/tex]

Answer:

The correct option is D

Step-by-step explanation:

The given numbers are

√(7²), √7, 4/5, √0.8, (√5)²

Now, let us check their real values.

√(7²) = 7

√7 ≈ 2.646

4/5 = 0.8

√0.8 ≈ 0.894

(√5)² = 5

Now, checking the options,

A doesn't apply

B doesn't appy

C doesn't apply

D applies because √7 = 2.646 is greater than 4/5 = 0.8 because 4/5 is less than 1 and the square root of a number greater than 1 is greater than 1.

Answer:

So I'm assuming we need the denominator to be 0. The only number that will satisfy this is -8.

The greatest common factor of numbers 14 and 38 is 2.

To find the greatest common factor (GCF) of 14 and 38, we can determine the largest positive integer that divides both numbers evenly.

To begin, let's find the factors of each number:

Factors of 14: 1, 2, 7, 14

Factors of 38: 1, 2, 19, 38

The common factors between 14 and 38 are 1 and 2.

However, the greatest common factor, so the GCF is 2.

Therefore, the greatest common factor of 14 and 38 is 2.
