The explicit rule for the given sequence is to add 3.5 to each previous term.

The given sequence is:

10.5, 14, 17.5, 21, 24.5, ...

The explicit rule for this sequence is that each term is obtained by adding 3.5 to the previous term. So, the nth term of the sequence can be represented by the formula:

Tn = Tn-1 + 3.5

where Tn is the nth term of the sequence and Tn-1 is the previous term.

Final answer:

The explicit rule for the sequence 10.5, 14, 17.5, 21, 24.5, ... is a_n = 7 + 3.5n.

Explanation:

The sequence given is 10.5, 14, 17.5, 21, 24.5, ... and we need to find an explicit rule for this sequence in simplified form. Observing the sequence, we see that each term is increasing by 3.5. Therefore, the common difference in this arithmetic sequence is 3.5. We can express the nth term of the sequence using the formula:

an = a1 + (n - 1)d, where a1 is the first term and d is the common difference.

Since the first term a1 is 10.5 and d is 3.5, the rule for the nth term is:

which simplifies to an = 7 + 3.5n.

Answer:

It is not likely that you will choose a person whose favorite color is red.

It is most likely that you will choose a person whose favorite color is something other than red.

Step-by-step explanation:

The probability that you choose a student who picked red as his or her favorite color is 45%, but the probability that you choose a person who picked another color is 55%.

It is not likely that you will choose a person whose favorite color is red. It is most likely that you will choose a person whose favorite color is blue. The probability that you choose a student who picked red as his or her favorite color is 10%, but the probability that you chose a person who picked another color is 90%.

To solve this problem, we need to analyze the given percentages of students who chose each color as their favorite. The percentages provided are as follows:

- Red: 10%

- Blue: 40%

- Green: 20%

- Yellow: 15%

- Purple: 10%

- Orange: 5%

The total probability of all possible outcomes must equal 100%. In this case, the sum of the percentages of all colors equals 100%, confirming that the probabilities are correctly distributed among the color choices.

Now, let's address the first part of the question: It is/is not likely that you will choose a person whose favorite color is red. Since red has the lowest percentage (10%), it is the least likely choice among all the colors. Therefore, it is not likely that you will choose a person whose favorite color is red.

Next, we determine which color is most likely to be chosen. Since blue has the highest percentage (40%), it is the most likely choice. Thus, it is most likely that you will choose a person whose favorite color is blue.

To calculate the probability of choosing a student who picked red as their favorite color, we use the given percentage for red, which is 10%. This is the probability of randomly selecting a student who prefers red.

Finally, to find the probability of choosing a person who picked any color other than red, we subtract the probability of choosing red from the total probability (100%). This gives us 100% - 10% = 90%. Therefore, the probability that you chose a person who picked another color is 90%.

In conclusion, the probability of choosing a student who likes red is 10%, and the probability of choosing a student who likes any other color is 90%. The most likely color to be chosen is blue.

Step-by-step explanation:

Given that ,

⇒ y = 1/4x and

⇒ 5x - 8y = 33

We can write 1st equation as ,

⇒ 4y = x

Put x = 4y in 2nd Equation ,

⇒ 5*4y - 8y = 33

⇒ 20y - 8y = 33

⇒ 12y = 33

⇒ y = 33/12

Put this in 1st ,

⇒ 33/12 = 1/4 x

⇒ x = 33/12 × 4

⇒ x = 33/3

⇒ x = 11 .

Answer:

15. h⁻¹ (x) = 5x-6/2

16. (g.f)x = 4x^2 -2x -1

Step-by-step explanation:

15. Find Inverse of h(x) =  2x+6 /5

Let y = 2x+6/5 we need to find value of x

Multiplying both sides with 5

5y = 2x+6

Adding -6 on both sides

5y -6 = 2x

Dividing both sides by 2

5y-6/2 = x

Now replace y with x our answer will be:

h⁻¹ (x) = 5x-6/2

16. f(x) =2x-1 and g(x) = x^2 -2 find (g.f)x

(g.f)x can be written as: g(f(x))

We know f(x) = 2x-1 so, put value of f(x) into x of g(x).

Putting values we get:

(g.f)x = g(f(x))= (2x-1)^2 -2

                   = 4x^2 -2x +1 -2

                   = 4x^2 -2x -1

so, (g.f)x = 4x^2 -2x -1

Answer:

[tex]a_n=78-6n[/tex]

[tex]a_{14}=78-6(14)[/tex]

Step-by-step explanation:

To solve this, we are using the formula for the nth term of an arithmetic progression:

[tex]a_n=a_1+(n-1)d[/tex]

where

[tex]a_1[/tex] is the first term of the progression

[tex]d[/tex] is the difference

[tex]n[/tex] is position of the term in the progression

We know for our problem that the bottom row contains 72 bricks, so [tex]a_1=72[/tex]. We also know that each row above decreases by 6 bricks, so the difference is -6 ([tex]d=-6[/tex]).

Replacing the values:

[tex]a_n=72+(n-1)(-6)[/tex]

[tex]a_n=72-6n+6[/tex]

[tex]a_n=72-6n+6[/tex]

[tex]a_n=78-6n[/tex]

Where [tex]n[/tex] is the row

Since we want to now the number of bricks in the 14th row, [tex]n=14[/tex]:

[tex]a_{14}=78-6(14)[/tex]

[tex]a_{14}=78-84[/tex]

[tex]a_{14}=-6[/tex]

Since bricks can't be negative, we can conclude that this is an impossible real-life situation.

[tex]\bf r=\sqrt{\cfrac{A}{P}}-1~~ \begin{cases} P=425\\ A=470 \end{cases}\implies r=\sqrt{\cfrac{470}{425}}-1\implies r=\sqrt{\cfrac{94}{85}}-1 \\\\\\ r\approx 0.051609\implies \stackrel{\textit{converting it to percentage}}{r\approx 0.051609\cdot 100}\implies r\approx 5.1609\implies \stackrel{\textit{rounded up}}{r=5.2}[/tex]

Answer:

6 x + 12

Step-by-step explanation:

Hexagon = 6 sides

1 side = x + 2

( Multiply by 6 to get 6 sides )

6 sides = 6 x + 12

The perimeter of a regular hexagon with a side length of x + 2 would be 6x + 12. This is achieved by multiplying the length of one side (x + 2) by 6 (total sides in a hexagon).

The perimeter of any regular shape is given by the sum of its sides. In a regular hexagon, all sides are equal. Therefore, if one side is x + 2, then the perimeter would be six times that side length. This is because a hexagon has six sides. So, if we multiply the length of one side (x + 2) by 6 the result will be the total perimeter. Hence, the perimeter of the regular hexagon would be 6(x + 2), which simplifies to 6x + 12.

Answer:

Rational

Step-by-step explanation:

1.256 is not a whole #, and it's also not an integer. An integer is basically whole #s and their opposites. The # is not irrational. 1.256 is a terminating decimal, and can be turned into a fraction. 1.256 = 1 32/125.

The number 1.256 is a rational number because it can be expressed as a ratio of two integers (1256/1000). It is not a whole number or an integer due to its decimal component.

The question is whether the number 1.256 belongs to the sets of rational numbers, whole numbers, or integers. Contrary to the student's initial thought, 1.256 is not an irrational number. Instead, it is a rational number because it can be expressed as a ratio of two integers.

Specifically, 1.256 can be written as 1256/1000, where both the numerator and denominator are integers. Therefore, this number belongs to the set of rational numbers. It is not a whole number or an integer, as both of these sets require numbers without fractional or decimal components.

Answer:

92.4% or 73/79

Step-by-step explanation:

You have to add up all the individual songs, which is 158. Then add up the number of songs that aren't classical, which is 146. Then divide 146 by 158 which gives you your answer.

To find the probability that a randomly selected song from Suki's playlist is not a classical song, follow these steps:
1. **Find the total number of songs**: Add up the number of rock songs, dance songs, and classical songs to get the total number of songs in Suki's playlist.
  Total number of songs = Number of rock songs + Number of dance songs + Number of classical songs
  Total number of songs = 54 rock songs + 92 dance songs + 12 classical songs
  Total number of songs = 158 songs
2. **Calculate the probability of selecting a classical song**: To calculate the probability of selecting a classical song, divide the number of classical songs by the total number of songs.
  Probability of selecting a classical song = Number of classical songs / Total number of songs
  Probability of selecting a classical song = 12 / 158
3. **Calculate the probability of not selecting a classical song**: The probability of not selecting a classical song is the complement of the probability of selecting a classical song. To get this probability, subtract the probability of selecting a classical song from 1.
  Probability of not selecting a classical song = 1 - Probability of selecting a classical song
  Probability of not selecting a classical song = 1 - (12 / 158)
4. **Compute the final probability**: Perform the subtraction from step 3 to get the final probability.
  Probability of not selecting a classical song = 1 - (12 / 158)
  Probability of not selecting a classical song ≈ 0.92405 (rounded to five decimal places)
Therefore, when Suki's music player randomly selects a song, the probability that the song will not be a classical song is approximately 0.92405, or 92.405%.

Answer:

112.5 km

Step-by-step explanation:

The lorry needed 45 minutes to travel the remaining 0.4 of the journey and was traveling at 60 km/hr.

First, convert minutes to hours:

45 min × (1 hr / 60 min) = 0.75 hr

Now use distance equation:

distance = rate × time

0.4d = 60 × 0.75

d = 112.5

The distance between the towns is 112.5 km.

The answer is:

It takes Ella 3 seconds to do a push-up and 3 seconds to do a sit up.

To find how many seconds Ella took to do a push-up and a sit-up we must write two equations using the given information.

Let be "x" the time needed to push-ups and "y" be the time needed to do sit-ups.

So, writing the equations we have:

First equation,

If she can do 13 push-ups and 7 sit-ups in 60 seconds, we have:

[tex]13x+7y=60[/tex]

Second equation,

If she can do 13 push-ups and 19 sit-ups in 96 seconds, we have:

[tex]13x+19y=96[/tex]

Now, creating a system of equations, and using the reduction method to solve it, we have:

[tex]\left \{ {{13x+7y=60} \atop {13x+19y=96}} \right.[/tex]

Multiplying the first equation by -1, we have:

[tex]\left \{ {{-13x-7y=-60} \atop {13x+19y=96}} \right.[/tex]

[tex]\left \{ {{-13x-7y=-60} \atop {13x+19y=96}} \right\\\\12y=36\\\\y=\frac{36}{12}=3[/tex]

Then, substituting "y" into the first equation, we have:

[tex]13x+7y=60[/tex]

[tex]13x+7(3)=60[/tex]

[tex]13x+21=60[/tex]

[tex]13x=60-21=39[/tex]

[tex]x=\frac{39}{13}=3[/tex]

Hence, we have that It takes Ella 3 seconds to do a push-up and 3 seconds to do a sit up.

Answer:

x=22

Step-by-step explanation:

2(x+5)=3(x-4)

2x+10=3x-12

-x=-22

x=22

Step 1: Distribute the numbers outside the parentheses to each number inside the parentheses

(2 * x) + (2 * 5) = (3 * x) + (-4 * 3)

2x + 10 = 3x - 12

Step 2: Combine like terms

2x goes with 3x. To do this subtract 2x to both sides (subtraction is the opposite of addition)

(2x - 2x) + 10 = (3x - 2x) - 12

0 + 10 = x - 12

10 = x - 12

10 goes with -12. To do this add 12 to both sides (addition is the opposite of subtraction)

10 + 12 = x + (-12 + 12)

22 = x + 0

22 = x

Check:

2(22 + 5) = 3(22 - 4)

2(27) = 3(18)

54 = 54
