Answer:

Area = 121pi/12

~= 31.66 sq units

Step-by-step explanation:

They are talking about looking at an umbrella like its a circle. The radius is 11 units. That is from the center to the edge.

Consecutive means "in a row" or "next to each other" The 12 "ribs" are the like skeleton structure in the umbrella. But they cut the umbrella into 12 areas. They are asking for the area of one "slice". It is 1/12 of the area of the whole circle.

Area of a circle is

A = pi × r^2

Area of one slice is 1/12 of the whole.

A(1 slice)

= 1/12× pi × r^2

To find the probability that at least 2 of the comments are positive, we can use the concept of complementary probability. We'll find the probability that fewer than 2 comments are positive and then subtract it from 1 to get the desired probability.

Let's consider the following scenarios:

1. No comments are positive (all 10 comments are negative).

2. Exactly 1 comment is positive.

Let's calculate the probability of each scenario:

1. Probability of no comments being positive:

P(No positive comments) = (0.9)^10 = 0.3487 (rounded to four decimal places)

2. Probability of exactly 1 comment being positive:

P(Exactly 1 positive comment) = 10 * (0.1)^1 * (0.9)^9 ≈ 0.3874 (rounded to four decimal places)

To find the probability that at least 2 comments are positive, we subtract the sum of the above probabilities from 1:

P(At least 2 positive comments) = 1 - P(No positive comments) - P(Exactly 1 positive comment)

                             = 1 - 0.3487 - 0.3874

                             ≈ 0.2639 (rounded to four decimal places)

Therefore, the probability that at least 2 of the comments are positive is approximately 0.2639 or 26.39%

The angles of a triangle with side lengths 5 , 12 and 13 are 90°, 22.63°, 67.38°.

In trigonometry, the law of cosines, also known as the law of cosines or cosine formula, basically relates the length of a triangle to one cosine of its angle. It states that if we know the lengths of two sides of a triangle and the angle between them, we can determine the length of the third side. c² = a²+ b² – 2ab cosγ

where a, b, c are the sides of the triangle and γ is the angle between a and b, see image above.

To find the length of a side of a triangle, take △ABC according to the cosine formula, which can be written as follows.

We have , a = 5 , b = 12 , c= 13

cos α =( 12² + 13² - 5² )/2×12×13= 288/312

=> α = cos⁻¹(0.923 ) = 22.63°

cos β = (5² + 13² - 12² )/2×13×5 = 50/130

=> β = cos⁻¹(5/13) = 67.38°

cos γ = (12² + 5² - 13² )/2×12×5= 0

=> γ = cos⁻¹(0) = 90°

Hence, the required angles are 90°, 22.63°, 67.38°.

Answer:  You would need a score of 96 on your last exam.

Step-by-step explanation:

If you take the 90 average and multiply it by 4, you get 360.  If you add your first 3 exam grades and subtract them from 360, then you get 96 as your final score.  To check your work, add the 4 exam scores and find the average.  The average is 90.

(Pls mark me brainliest)  Thanks!

Have a great day!

Answer:

96

Step-by-step explanation:

The average of a set of data can be found by taking the sum of the values in the data divided by the number of values.

\(\boxed{\text{Average of 4 exams}= \frac{\text{Total score of 4 exams}}{4}}}\)

Let the score of the next exam be x.

\(90=\frac{x+80+93+91}{4}\)

Multiply both sides by 4:

360= x +264

Subtract both sides by 264:

x= 360 -264

x= 96

Thus, a grade of 96 is needed on the next exam.

Answer:

Both f(x) and g(x) have the same output value at x = 5

Step-by-step explanation:

When we are writing a function, while x gives the input value, writings like f(x), g(x) or h(x) will represent the output values of the input value of x

Now, looking at the relation, we are told that the value of f(x) = g(x) at x = 5

What this mean is that at x = 5; the output value of g(x) is the same as the output value of f(x)

Hence, we can conclude that both functions have the same output value at the given input value of x = 5

The revenue earned per minute of the movie is approximately $8.9 x 10^7.

To calculate the revenue earned per minute of the movie, we need to divide the total revenue by the duration of the movie in minutes.

Revenue earned per minute = Total revenue / Duration of the movie

Total revenue = $81.1 x 10^9

Duration of the movie = 9.1 x 10^1 minutes

Revenue earned per minute = ($81.1 x 10^9) / (9.1 x 10^1)

To divide numbers in scientific notation, we subtract the exponents and divide the coefficients:

Revenue earned per minute = $81.1 x 10^(9-1) / 9.1

Simplifying the exponent:

Revenue earned per minute = $81.1 x 10^8 / 9.1

Dividing the coefficients:

Revenue earned per minute ≈ $8.9 x 10^7

Answer:

750$

Step-by-step explanation:

\(Amount= 300*\frac{1050}{420} =750\)

It will cost approximately $750.01 to tile a room with an area of 1,050 square feet.

To find out how much it will cost to tile a room with 1,050 square feet, we can set up a proportion using the given information.

Cost₁: The cost to tile the first room with an area of 420 square feet, which is $300.

Area₁: The area of the first room, which is 420 square feet.

Cost₂: The cost to tile the second room with an unknown area, which we want to find.

Area₂: The area of the second room, which is 1,050 square feet.

We can set up the proportion:

Cost₁ / Area₁ = Cost₂ / Area₂

Substituting the known values:

$300 / 420 sq ft = Cost₂ / 1,050 sq ft

Now we can solve for Cost₂:

Cost₂ = ($300 / 420 sq ft) * 1,050 sq ft

Calculating:

Cost₂ = $0.7143 * 1,050 sq ft

Cost₂ ≈ $750.01

Therefore, it will cost approximately $750.01 to tile a room with an area of 1,050 square feet.

Step-by-step explanation:

In order to determine the initial investment, use the following formula for the composed interest:

where:

P: initial investment = ?

r: interest rate = 6% = 0.06

n: number of times per time period = 6

t: time period = 5 x 2 = 10

Hence, the initial investment was 19,273.13

1. The first 9 terms of the sequence are: 2, 3, -1, 8, -9, 26, -43, 96, -181.

3. Based on the differences between consecutive terms, we observe that they are not constant, indicating that the sequence is neither arithmetic nor geometric.

4. The sum of the first 200 terms of the arithmetic sequence is 121,800.

5. The sum of the first 8 terms of the geometric sequence is 18.

1. To find the terms of the sequence, we can use the given recursive formula and initial values:

s₁ = 2

s₂ = 3

sₙ = n - 2(sₙ₋₁ - 1)

Using these values and the recursive formula, we can calculate the first 9 terms:

s₃ = 3 - 2(s₂ - 1) = 3 - 2(3 - 1) = 3 - 2(2) = 3 - 4 = -1

s₄ = 4 - 2(s₃ - 1) = 4 - 2(-1 - 1) = 4 - 2(-2) = 4 + 4 = 8

s₅ = 5 - 2(s₄ - 1) = 5 - 2(8 - 1) = 5 - 2(7) = 5 - 14 = -9

s₆ = 6 - 2(s₅ - 1) = 6 - 2(-9 - 1) = 6 - 2(-10) = 6 + 20 = 26

s₇ = 7 - 2(s₆ - 1) = 7 - 2(26 - 1) = 7 - 2(25) = 7 - 50 = -43

s₈ = 8 - 2(s₇ - 1) = 8 - 2(-43 - 1) = 8 - 2(-44) = 8 + 88 = 96

s₉ = 9 - 2(s₈ - 1) = 9 - 2(96 - 1) = 9 - 2(95) = 9 - 190 = -181

Therefore, the first 9 terms of the sequence are: 2, 3, -1, 8, -9, 26, -43, 96, -181.

2. To compute the value of 1 $, we need to substitute n = 1 into the recursive formula:

s₁ = 1 - 2(s₀ - 1)

Since s₀ is not given in the question, we need additional information or assumptions about its value to proceed with the calculation. Please provide the value or any additional information about s₀ for a more accurate calculation.

3. To determine whether the sequence from question 1 is arithmetic, geometric, or neither, we need to examine the differences between consecutive terms.

The given recursive formula does not explicitly indicate an arithmetic or geometric relationship. However, we can calculate the differences between consecutive terms to identify any patterns:

Difference between s₂ and s₁: 3 - 2 = 1

Difference between s₃ and s₂: (-1) - 3 = -4

Difference between s₄ and s₃: 8 - (-1) = 9

Difference between s₅ and s₄: (-9) - 8 = -17

Difference between s₆ and s₅: 26 - (-9) = 35

Difference between s₇ and s₆: (-43) - 26 = -69

Difference between s₈ and s₇: 96 - (-43) = 139

Difference between s₉ and s₈: (-181) - 96 = -277

Based on the differences between consecutive terms, we observe that they are not constant, indicating that the sequence is neither arithmetic nor geometric.

4. To find the sum of an arithmetic sequence, we can use the formula: Sn = (n/2)(2a + (n - 1)d), where Sn is the sum of the first n terms, a is the first term, and d is the common difference.

First term (a) = 12

Common difference (d) = 6 (obtained by subtracting the first term from the second term)

We need to find the sum of the first 200 terms (n = 200). Substituting these values into the formula, we get:

S200 = (200/2)(2(12) + (200 - 1)(6))

    = 100(24 + 199(6))

    = 100(24 + 1194)

    = 100(1218)

    = 121,800

Therefore, the sum of the first 200 terms of the arithmetic sequence is 121,800.

5. To find the sum of a geometric sequence, we can use the formula: Sn = a(1 - rⁿ) / (1 - r), where Sn is the sum of the first n terms, a is the first term, r is the common ratio, and n is the number of terms.

First term (a) = 12

Common ratio (r) = 18/12 = 3/2 (obtained by dividing the second term by the first term)

We need to find the sum of the first 8 terms (n = 8). Substituting these values into the formula, we get:

S8 = 12(1 - (3/2)⁸) / (1 - (3/2))

  = 12(1 - (6561/256)) / (1/2)

  = 12(1 - 6561/256) / (1/2)

  = 12(1 - 81/4) / (1/2)

  = 12(1 - 20.25) / (1/2)

  = 12(0.75) / (1/2)

  = 9 / (1/2)

  = 9 * 2

  = 18

Therefore, the sum of the first 8 terms of the geometric sequence is 18.
