Answer & Step-by-step explanation:

The following sentence correctly uses parallel structure: "The scientific method consists of proposing your hypothesis, conducting your experiment, analyzing your data, and reporting your findings." In this sentence, all of the phrases are in the same form and describe actions that are part of the scientific method. Each phrase begins with a verb (proposing, conducting, analyzing, and reporting) and is followed by a noun that describes the action (hypothesis, experiment, data, and findings). This structure is parallel because each phrase has the same grammatical structure and describes a similar action.

The other sentences do not use parallel structure because they do not have the same grammatical structure or they do not describe similar actions. For example, in the first sentence, the phrases "propose a hypothesis" and "end with a reporting" are not parallel because they do not have the same grammatical structure. In the second sentence, the phrases "proposing your hypothesis" and "reporting your findings" are not parallel because they do not describe the same type of action (proposing is a mental process, while reporting is a physical action). In the third sentence, the phrases "begins with a hypothesis" and "reporting findings" are not parallel because they do not have the same grammatical structure (one begins with a verb and the other ends with a verb). Finally, in the fourth sentence, the phrases "hypothesize" and "reporting" are not parallel because they do not have the same grammatical structure (one is a verb and the other is a gerund).

Answer:

The scientific method begins with a hypothesis, continues with an experiment, then analyzing data, and reporting findings

Answer: 4 and 1

Step-by-step explanation:

Both ∠4 and ∠1 are equal angles. Both the angles are beside a right angle and you can measure it. The other answers are over 90 degrees, or below 90. This is because they either combine a 90 degree angle with another angle, or that they are too small and obvious that they are not complementary.

Answer:

<2 and <4

complimentary <s add up to 90 °

Final Answer: 21.6%

Multiply by 100 and round to nearest 10th

Answer:The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

The percentage decrease in the number of students from last year to the current year is 6.67%.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Last year:

Number of boys = 125

Number of girls = 100

Total number of students = 225

This year:

The number of boys:

= 125 - (8% of 125)

= 125 - 8/100 x 125

= 125 - 10

= 115

The number of girls:

= 100 - (5% of 100)

= 100 - 5

= 95

Total number of students = 115 + 95 = 210

The percentage decrease in the number of students from last year to the current year.

= [(Number of students last year - Number of students this year) / Number of students last year] x 100

= (225 - 210)/225 x 100

= 15/225 x 100

= 6.67%

Thus,

The percentage decrease in the number of students from last year to the current year is 6.67%.

Answer: The correct answer is:

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Step-by-step explanation:

A number times fifteen would be n • 15 or just n15.
The reason it is not 15n is because it asks a "number" which in this case is represented by  the letter n. That letter is now multiplied (times) by 15. So therefore the number "n" times 15 is n15.

Answer:

g43 = 79.5

Step-by-step explanation:

geometric sequence = ar^(n-1), where a is first term and r is common ratio.

g23 = ar^(23-1) = ar^22 = 16.

g28 = ar^27 = 24.

now do g28/g23:

(ar^27) / (ar^22) = 24/16,

a^(1-1) r^(27-22) = 24/16,

a^0 r^5 = 24/16,

r^5 = 24/16 = 1.5,

r = (1.5)^1/5 ≈ 1.084.

ar^22 = 16,

a = 16/(r^22) ≈ 2.687.

so g43 = ar^42 ≈ (2.687)(1.084)^42 = 79.5

Answer: In the first 2 hours, Doug drove 2 * 50 = <<250=100>>100 miles on the state road.

In the next 3 hours, he drove 3 * 60 = <<360=180>>180 miles on the interstate highway.

Therefore, he drove a total of 100 + 180 = <<100+180=280>>280 miles.

Since we don't know his distance from home before he began driving, we cannot calculate his distance from home after 5 hours of driving.

Answer: The relationship between the decimals for 2/6 and 4/6 is that the decimal for 4/6 is twice the decimal for 2/6.

When we simplify 2/6, we get 1/3, which is equivalent to 0.33 as a decimal. When we simplify 4/6, we get 2/3, which is twice the value of 1/3. So the decimal for 4/6 is twice the decimal for 2/6, which means that they have a proportional relationship.

Answer:

D. 75 cm²

Step-by-step explanation:

We are asked to find the area of a scaled map.

A scale factor is a change in the size, or ratio of a shape, or object.

The value of the scale factor represents how much larger the shape or object will become.

First, let's identify what is given to us.

Given:

We should begin by enlarging the map with the given scale factor. In order to find the dimensions of the scaled map, we should multiply the given dimensions of the original map by the scale factor.

Multiply:

\(4 \times 2.5 = 10 \ cm\)

\(3 \times 2.5 = 7.5 \ cm\)

Next, we should find the area of the scaled map by multiply the dimensions together.

\(A = L \times W\)

Multiply:

\(A = 10 \times 7.5\)

\(A = 75 \ cm^{2}\)

The area of the scaled map is D. 75 cm².

Answer:

0.25

Step-by-step explanation:

If the person made it 105 out of 140 times, that can be written as a fraction: 105/140

Then, you just turn the fraction into a decimal by dividing the numerator by the denominator.

105 divided by 140 = 0.75

0.75 is the probability that it does hit the board, so we can subtract 0.1-0.75 to give us the probability that is doesn't hit the board. This would give us 0.25

The experimental probability that the player does not hit the dartboard is,

⇒ 1 / 14

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times.

Hence, Number of not hit dartboard is,

⇒ 140 - 105

⇒ 35

Thus, The experimental probability that the player does not hit the dartboard is,

⇒ 35 / 140

⇒ 7 / 28

⇒ 1 / 14

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.
