The solution of the given problem of arithmetic mean comes out to be  given series is therefore a geometric sequence.

A list's values are added up to get the average values, also known as the company's means, which is then multiplied by the maximum population of list elements. Similar development patterns can be seen in math. The median of the actual numbers 5, 8, and 9 is 3, while for mean of the real figures 5, 7, as well as 9 is 4, and the number 21 increased by three (there are currently several three numbers) = seven. This is demonstrated by the following equation.

Here,

It is a geometric sequence that is provided.

A mathematical sequence known as a geometric sequence is one in which each term following the first is obtained by multiplying the preceding term by a fixed ratio known as the common ratio. A geometric sequence's overall formula is

=>  a = a1 + [tex]r^{(n-1)[/tex] (n-1)

where r is the common ratio, n is the amount of terms, and an is the nth term. A1 is the first term.

The first word in the listed order is:

=> a1 = 1/2(4)⁰ = 1/2

Any term can be divided by the preceding term to find the common ratio:

=>  a2/a1 = (1/2(4)¹)/(1/2(4)⁰) = 4/2 = 2

=>  a3/a2 = (1/2(4)²)/(1/2(4)¹) = 4/2 = 2

so forth.

This series is a geometric sequence because the common ratio is constant.

The given series is therefore a geometric sequence.

Answer:

Lowest possible score is 59.865 and you can still maintain an 80 by the end.

Step-by-step explanation:

Considering the expression of a line, an equation for the line best fit to the points (0, 60) and (4, 90) is y=7.5x +60.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂), the slope m can be calculated using:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope m and the value of one of the points, the value of the ordinate to the origin b can be obtained.

In this case, being (x₁, y₁)= (0, 60) and (x₂, y₂)= (4, 90), the slope can be calculated as:

m= (90 - 60)÷ (4-0)

m= 30÷ 4

m= 7.5

Considering point 1 and the slope m, you obtain:

60= 7.5×0 + b

60= 0 +b

60= b

Finally, the equation of the line is y=7.5x +60.

Answer:

the average velocity of the ball on the interval [1, 3/2] is -808 ft/s.

Step-by-step explanation:

The height of the ball at time t is given by the formula:

s(t) = -16t^2 + 50t + 1200

We need to find the average velocity of the ball on the interval [1, 3/2]. The average velocity is defined as the change in position divided by the change in time, or:

average velocity = (s(3/2) - s(1)) / (3/2 - 1)

Substituting the formula for s(t), we get:

average velocity = ((-16(3/2)^2 + 50(3/2) + 1200) - (-16(1)^2 + 50(1) + 1200)) / (3/2 - 1)

Simplifying and solving for the average velocity, we get:

average velocity = (430 - 1234) / (1/2) = -808 ft/s

Therefore, the average velocity of the ball on the interval [1, 3/2] is -808 ft/s.

How to find angle in triangle ?

To find the measure of an angle in a triangle, you need to know the measures of the other two angles in the triangle. Since the sum of all angles in a triangle is always 180 degrees, you can use this fact to calculate the measure of the third angle.

There are a few different methods we can use to find the measure of an angle in a triangle:

Subtract the measures of the other two angles from 180 degrees. This works for any triangle, regardless of its shape or size.

Use the fact that the angles opposite equal sides of a triangle are equal. This is known as the "angle-side-angle" (ASA) theorem. For example, if you know the lengths of two sides of a triangle and the angle between them, you can use the Law of Cosines to find the third side and then use the Law of Sines to find the opposite angle.

Use the fact that the angles in a right triangle are related by the Pythagorean Theorem. If you know the lengths of two sides of a right triangle, you can use the Pythagorean Theorem to find the length of the third side, and then use trigonometric ratios (sine, cosine, tangent) to find the measure of the angle opposite the known side.

Use the fact that the angles in an equilateral triangle are all equal. If you know that a triangle is equilateral, you can simply divide 180 degrees by 3 to find the measure of each angle.

In a triangle, the sum of all angles is always 180 degrees. Therefore, we can use this fact to find the measure of angle Y:

angle Z + angle X + angle Y = 180 degrees

Substituting the given values:

113 degrees + 28 degrees + angle Y = 180 degrees

Simplifying and solving for angle Y:

141 degrees + angle Y = 180 degrees

angle Y = 180 degrees - 141 degrees

angle Y = 39 degrees

Therefore, angle Y measures 39 degrees.

    |<---- 44 cm ---->|

    |                  |

After x is cut off each rod, the remaining lengths can be arranged to form a right triangle, as shown below:

               +---------(44-x)--------+

               |                        |

   +-----------+------------------------+

               |         x              |

b) To model the situation, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the hypotenuse. In this case, we have:

(20-x)^2 + (41-x)^2 = (44-x)^2

c) To find the length that is cut off, we can solve the equation from part (b) for x. First, we can simplify the equation by expanding the squares:

400 - 40x + x^2 + 1681 - 82x + x^2 = 1936 - 88x + x^2

Simplifying further, we get:

2x^2 - 18x - 855 = 0

We can solve for x by using the quadratic formula:

x = [18 ± sqrt(18^2 + 4(2)(855))] / (2(2))

x = [18 ± sqrt(7404)] / 4

x ≈ 16.98 or x ≈ -24.98

Since x represents a length that is cut off each rod, it must be positive. Therefore, we can discard the negative solution and conclude that the length that is cut off is approximately 16.98 cm.

d) Using the length that is cut off, we can find the dimensions of the right triangle by substituting x = 16.98 into the expressions for the remaining lengths. We get:

(20 - 16.98) = 3.02 cm

(41 - 16.98) = 24.02 cm

(44 - 16.98) = 27.02 cm

Therefore, the dimensions of the right triangle are 3.02 cm, 24.02 cm, and 27.02 cm.

Answer:

Sandra walked longer by 240 - 230 = 10 meters.

Step-by-step explanation:

To find out who walked longer and by how much, we need to calculate the distance walked by each person.

For Jay who walked two rounds around Ace Park, the distance walked is:

Distance = 2 × (length + width) = 2 × (75 + 40) = 230 meters

For Sandra who walked two rounds around Lewis Park, the distance walked is:

Distance = 2 × (length + width) = 2 × (90 + 30) = 240 meters

Therefore, Sandra walked longer by 240 - 230 = 10 meters.

Answer: Let's begin by assigning variables to represent the dimensions of the room. Let's use "l" to represent the length and "w" to represent the width.

We know that the length of the room is 5 feet longer than twice the width, so we can write an equation:

l = 2w + 5

We also know that the perimeter of the room is 178 feet. The formula for the perimeter of a rectangle is:

perimeter = 2(length + width)

Substituting the equation we found for the length, we get:

178 = 2(2w+5 + w)

Simplifying, we can combine like terms and solve for w:

178 = 2(3w+5)

89 = 3w+5

84 = 3w

w = 28

Now that we know the width is 28 feet, we can use the equation for the length to find the length:

l = 2w+5 = 2(28)+5 = 61

Therefore, the dimensions of the room are 61 feet by 28 feet.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

There are four 7s in a deck of 52 cards, so the probability of drawing a 7 is 4/52, which simplifies to 1/13. The odds in favor of drawing a 7 are the ratio of the probability of drawing a 7 to the probability of not drawing a 7, which is:

(1/13) : (12/13

We can simplify this ratio by dividing both terms by the greatest common factor, which is 1:

(1/13) : (12/13) = 1 : 12

Answer: 46.39 grams of radium

Step-by-step explanation:

We can use the half-life formula to solve this problem:

A = A₀(1/2)^(t/t₁/₂)

where:

A₀ = initial amount (present)

A = final amount (in 710 years)

t = time elapsed (710 years)

t₁/₂ = half-life (1690 years)

First, we need to calculate the number of half-lives that will occur in 710 years:

n = t / t₁/₂

n = 710 / 1690

n ≈ 0.42

This means that in 710 years, the amount of radium will be reduced to half its current amount (1/2). And then reduced to half again (1/2 * 1/2) in another 1690 years.

Now we can calculate the final amount of radium after 710 years:

A = A₀(1/2)^n

A = 70(1/2)^0.42

A ≈ 46.39 grams

Therefore, after 710 years, approximately 46.39 grams of radium will be left.

The length and width οf the rectangle are 11 inches and 4 inches, respectively.

Area οf rectangle can be defined as prοduct οf length , breadth οf a rectangle.

Let's denοte the width οf the rectangle as w. Then accοrding tο the prοblem, the length οf the rectangle is 7 inches mοre than the width, sο we can express the length as w + 7.

The area οf the rectangle is given by:

[tex]A = length * width = (w + 7) * w = w^2 + 7w[/tex]

The perimeter οf the rectangle is given by:

[tex]P = 2 * (length + width) = 2 * (w + 7 + w) = 4w + 14[/tex]

According tο the problem, the area of the rectangle is equal to 2 inches mοre than 2 times the perimeter, so we can set up the following equation:

[tex]w^2 + 7w = 2(4w + 14) + 2[/tex]

Simplifying this equatiοn, we get:

[tex]w^2 + 7w = 8w + 28[/tex]

Subtracting 8w + 28 frοm both sides, we get:

[tex]w^2 - w - 28 = 0[/tex]

We can factοr this quadratic equation as:

[tex](w - 4)(w + 7) = 0[/tex]

Therefοre, we have twο sοlutiοns fοr w: w = 4 and w = -7. Hοwever, since the width οf the rectangle cannοt be negative, we reject the sοlutiοn w = -7 and chοοse w = 4 as the width οf the rectangle.

Then, the length οf the rectangle is w + 7 = 4 + 7 = 11 inches.

8 + 15 > x -------> x < 23

x + 15 > 8 -------> x > -7

So we have 7 < x < 23.
