The sum of the infinite geometric sequence that begins with 1/12, 1/18, 1/27 is 1/4.

To find the sum of the infinite geometric sequence that begins with 1/12, 1/18, 1/27, we first need to determine the common ratio, r.

To find the common ratio, we divide each term by the preceding term, as follows:

r = (1/18) ÷ (1/12) = 1/18 × 12/1

                         = 2/3

r = (1/27) ÷ (1/18) = 1/27 × 18/1

                          = 2/3

Since the common ratio is the same for all terms, this is a geometric sequence.

The formula for the sum of an infinite geometric sequence is:

sum = a / (1 - r)

where a is the first term and r is the common ratio.

Substituting the values we found, we get:

sum = (1/12) / (1 - 2/3)

       = (1/12) / (1/3)

       = 1/4

Therefore, the sum of the infinite geometric sequence that begins with 1/12, 1/18, 1/27 is 1/4.

We have proved that Angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.

To prove that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, we can use the following steps:

Step 1: Join points A and C with a line segment. Let's label the point where AC intersects with line segment BD as point E.

Step 2: Since line segment AC is drawn, we can consider triangle ABC and triangle ADC separately.

Step 3: In triangle ABC, we have angle B + angle ABC + angle BCA = 180 degrees (due to the sum of angles in a triangle).

Step 4: In triangle ADC, we have angle D + angle ADC + angle CDA = 180 degrees.

Step 5: From steps 3 and 4, we can deduce that angle B + angle ABC + angle BCA + angle D + angle ADC + angle CDA = 360 degrees (by adding the equations from steps 3 and 4).

Step 6: Consider quadrilateral ABED. The sum of angles in a quadrilateral is 360 degrees.

Step 7: In quadrilateral ABED, we have angle BAD + angle ABC + angle BCD + angle CDA = 360 degrees.

Step 8: Comparing steps 5 and 7, we can conclude that angle B + angle BCD + angle D = angle BAD + angle ABC + angle ADC.

Step 9: Rearranging step 8, we get angle BCD = angle BAD + angle ABC + angle ADC.

Therefore, we have proved that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.

Answer:

13 over 22

Step-by-step explanation:

because you want to change the denominator to where they can match. So 22 is where 11 and 2 can match. then you want to multiply the amount you multiplied with the denominator so 1 over 11 would be 2 over 22. And 1 over 2 would be 11 over 22. and then you can add. 11 plus 2 is 13 and you can keep the denominator the same. Therefore, the answer would be 13 over 22

Step-by-step explanation:

2. Lionel should be the correct answer.

3. we proved that  f(x) - (-g(x)) is equivalent to f(x)+ g(x).

Given that;

Dotty and Lionel are making a graph comparing a car's age with its gas mileage.

Dotty says the graph should show discrete points because the car sage is started in whole numbers of years.

Lionel says they should make a continuous line because age increases gradually, like time.

Now,

Clearly, The Lionel is correct because when we talk about the age, that means time and Time is continuous , never stopping or slowing down for anyone.

Thus, Lionel should be the correct answer.

3. f(x)-(-g(x)) is equivalent to f(x)+g(x)

Given:

functions f(x) = 3x - 7 and

g(x) = -2x+ 5.

we are asked to find whether  f(x) - (-g(x)) is equivalent to f(x)+ g(x).

f(x) = 3x-7

g(x) = -2x+5

-g(x) = -(-2x+5)

= 2x-5

First we determine:

f(x) + g(x) = 3x-7+(-2x+5)

f(x) + g(x) = 3x-7-2x+5

f(x) + g(x) = x-2

Now, we find:

f(x ) - (-g(x)) = 3x - 7 -(2x-5)

f(x ) - (-g(x)) = 3x-7-2x+5

f(x ) - (-g(x)) = x-2

Hence  f(x) - (-g(x)) is equivalent to f(x)+ g(x).

(a) the expected number of people with no complaint who left the HMO is:  0.25 × 120 = 30

(a) To find the expected number of people with no complaint who leave the HMO, we first need to calculate the total number of people who left the HMO:

32 + 56 + 32 = 120

The proportion of people with no complaint in the total sample is:

90 / (90 + 162 + 108) = 0.25

(b) Following the same steps as in part (a), we find that the proportion of people with a medical complaint in the total sample is:

162 / (90 + 162 + 108) = 0.45

Therefore, the expected number of people with a medical complaint who left the HMO is:

0.45 × 120 = 54

(c) Following the same steps as in parts (a) and (b), we find that the proportion of people with a nonmedical complaint in the total sample is:

108 / (90 + 162 + 108) = 0.30

Therefore, the expected number of people with a nonmedical complaint who left the HMO is:

0.30 × 120 = 36

(d) To find the test statistic, we can use the chi-square test for independence. The formula for the test statistic is:

χ² = Σ (O - E)² / E

where O is the observed frequency and E is the expected frequency.

Using the data from the table and the expected frequencies calculated in parts (a), (b), and (c), we get:

χ² = [(32 - 30)² / 30] + [(56 - 54)² / 54] + [(32 - 36)² / 36]

χ² ≈ 0.39

(e) The degrees of freedom for the chi-square test for independence are calculated as:

df = (r - 1) × (c - 1)

where r is the number of rows and c is the number of columns in the contingency table.

In this case, r = 3 and c = 2, so:

df = (3 - 1) × (2 - 1) = 2

(f) To find the critical value of the chi-square distribution with 2 degrees of freedom and a significance level of 0.01, we can use a chi-square table or calculator.

From the table, the critical value is approximately 9.21.

(g) The final conclusion is:

A. There is not sufficient evidence to reject the null hypothesis.

To make this conclusion, we compare the test statistic (0.39) to the critical value (9.21). Since the test statistic is smaller than the critical value, we do not have enough evidence to reject the null hypothesis that the proportions of people leaving the HMO are the same for each complaint group.

Step-by-step explanation:

The sample proportion is 0.530 and the z-critical value is 2.58 and the confidence interval at 99% is ( 0.503, 0.556 ).

Given that,

Because watching TV via digital streaming is becoming more and more common, tv advertising companies are having a harder time connecting with viewers. 53% of the 2343 American adults surveyed by the Harris Poll on November 13, 2012, claimed they had viewed digitally streamed television content on at least one device.

We have to find what is the sample proportion? firstly, the z-critical value is ? What is the confidence interval at 99%?

We know that,

n = 2343

Point estimate = sample proportion = \(\hat p\) = 0.530

1 - \(\hat p\) = 1 -0.530 = 0.470

At 99% confidence level

α = 1-0.99% =1-0.99 =0.01

α /2 =0.01/ 2= 0.005

Z(α /2) = Z0.005 = 2.576

Z (α/2) = 2.576 = 2.58

Margin of error = E = Z (α/2) × √((\(\hat p\) × (1 - \(\hat p\) )) / n)

=2.576 × (√(0.530×(0.470) /2343 )

= 0.027

A 99% confidence interval for population proportion p is ,

\(\hat p\)- E < p < \(\hat p\) + E

0.530 -0.027 < p < 0.530 +0.027

0.503 < p < 0.556

( 0.503, 0.556 )

Therefore, The sample proportion is 0.530 and the z-critical value is 2.58 and the confidence interval at 99% is ( 0.503, 0.556 ).

Step-by-step explanation:

the area (A) of the triangle is calculated as

A = \(\frac{1}{2}\) yz sin Y ( that is 2 sides and the angle between them )

where x is the side opposite ∠ X and z the side opposite ∠ Z

here y = XZ = 4.3 and z = XY = 7 , then

A = \(\frac{1}{2}\) × 4.3 × 7 × sin79°

   = 15.05 × sin79°

   ≈ 14.8 units² ( to 1 decimal place )

The sum of angle in a triangle is 180°

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC.

The sum of angle A, B and C is 180 i.e A+B +C = 180°

Also a triangle is a 3 sided polygon. The sum of of angle in a polygon is( n-2)180

How do we prove that the sum of angle in a triangle is 180°?

Since triangle is 3 sided, n= 3, because n denote the number if sides

therefore the sum of angle = (n-2) 180 = (3-2)×180

= 180°

Step-by-step explanation:

To find the amplitude, period, and frequency of a trigonometric function, you need to examine its equation. Trigonometric functions are typically written in the form:

f(x) = A * sin(Bx + C) + D

where:

• A represents the amplitude,

• B determines the frequency and period,

• C is a phase shift (if any), and

• D is a vertical shift (if any).

Here's how you can find each parameter:

1. Amplitude (A):

The amplitude represents the maximum displacement from the average or mean value of the function. It is the coefficient that multiplies the trigonometric function. In the equation f(x) = A * sin(Bx + C) + D, the amplitude is A.

2. Frequency (f) and Period (T):

The frequency and period are closely related. The period (T) is the length of one complete cycle of the function, while the frequency (f) is the number of cycles per unit of time. The frequency is the reciprocal of the period, so f = 1 / T.

To find the period, you need to look at the coefficient B. If the function is of the form sin(Bx), then the period is given by T = 2π / B. If the function is cos(Bx), the period remains the same.

3. Frequency (f):

Once you have the period (T), you can find the frequency (f) using f = 1 / T.

By examining the equation of the trigonometric function and following the steps above, you can determine the amplitude, period, and frequency of the function.

To find the amplitude, period, and frequency of a trigonometric function, you need to examine the equation representing the function. Here is a explanation.

Amplitude: The amplitude represents the maximum displacement or height of the function from its average or mean value. It is usually denoted as "A" in the trigonometric function equation. To find the amplitude, identify the coefficient multiplying the trigonometric function. If there is no coefficient, the amplitude is assumed to be 1.

Period: The period is the length of one complete cycle of the trigonometric function. It represents the distance between two consecutive peaks or troughs of the function. To find the period, identify the value inside the trigonometric function's argument (the value inside the parentheses) that determines the period. If there is no value, the period is assumed to be 2π.

Frequency: The frequency represents the number of cycles of the trigonometric function that occur per unit interval. It is the reciprocal of the period and is usually denoted as "f." The frequency can be calculated by taking the reciprocal of the period: f = 1/period. By analyzing the equation, you can determine the amplitude, period, and frequency of the trigonometric function, which provide essential information about its behavior and characteristics.
