Step-by-step explanation:

The value of r is approximately 0.62.

The sum of the first 3 terms of a geometric sequence is 30 1/2 and the sum of the 4th, 5th, and 6th term is 3 15/16. To determine the value of r, we can use the formula for the sum of a geometric sequence:

S_n = a_1 (1 - r^n) / (1 - r)

Where S_n is the sum of the first n terms, a_1 is the first term, and r is the common ratio.

For the first 3 terms, we have:

30 1/2 = a_1 (1 - r^3) / (1 - r)

For the 4th, 5th, and 6th terms, we can use the formula for the nth term of a geometric sequence:

a_n = a_1 r^(n-1)

So the 4th term is a_1 r^3, the 5th term is a_1 r^4, and the 6th term is a_1 r^5. The sum of these terms is:

3 15/16 = a_1 r^3 + a_1 r^4 + a_1 r^5

We can factor out a_1 r^3 to get:

3 15/16 = a_1 r^3 (1 + r + r^2)

Now we can substitute the expression for a_1 r^3 from the first equation into the second equation:

3 15/16 = (30 1/2) (1 - r) (1 + r + r^2)

Simplifying and rearranging terms, we get:

r^5 - 8r^4 + 15r^3 - 8r^2 + r = 0

This is a quintic equation, which cannot be solved algebraically. However, we can use numerical methods to find an approximate value of r. Using a graphing calculator, we find that r ≈ 0.62.

Therefore, the value of r is approximately 0.62.

The measure of arc ED is 78.7°

An arc of a circle is a portion of the circumference of a circle. It is defined by two endpoints and the arc itself.

The measure of an arc is given in degrees or radians, and it is determined by the angle that it subtends at the center of the circle.

Since FC is the diameter and arc FB is equivalent to arc BC. We can say:

arc FB + arc BC = 180°

arc FB = arc FB = 90°

Also, arc ED is twice the measure of arc CD. We can write:

arc ED = 2 * arc CD

arc CD =  (arc ED)/2

Since the sum arc FB and arc BC is 180°. We can say:

arc FE + arc ED + 0.5(arc ED) = 180°

62° + arc ED + 0.5(arc ED) = 180°

62° + 1.5(arc ED) = 180°

1.5(arc ED) = 180 - 62

1.5(arc ED) = 118

arc ED = 118/3

The standard deviation of the sample is 24. Therefore the correct option is, option b. 24.


The variance of a sample is the square of the standard deviation. In other words, the standard deviation is the square root of the variance. Therefore, to find the standard deviation of the sample, we need to take the square root of the variance:
√576 = 24

Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

Like the variance, if the data points are close to the mean, there is a small variation whereas the data points are highly spread out from the mean, then it has a high variance.

So, the standard deviation of the sample of 169 observations and variance 576 equals 24. The correct option is b.

Therefore, the perimeter of the square when its side length is 12 is 48 units.

The perimeter of an object is the space surrounding it. For instance, the yard around your house is fenced in. The perimeter of the barrier is its length. If the yard is 50 by 50 feet, your fence is 200 feet long.

Since a square has all equal sides, the perimeter of a square is just four times the length of one side. Therefore, the perimeter of the square when its side length is 12 is:

Perimeter = 4 x 12 = 48

To write a proportion to solve for the perimeter of a square when its side length is x, we can set up the following ratio:

12/x = 48/p

where p represents the perimeter of the square. We can cross-multiply to get:

12p = 48x

p = 4x

Now we can substitute 12 for x to find the perimeter when the side length is 12:

p = 4(12) = 48

A milkshake costs $3.50 and an ice cream sundae costs $4.75.

A system of linear equations is a set of two or more linear equations that contain the same variables. A linear equation is an equation of a straight line and has the form ax + by = c, where a, b, and c are constants and x and y are variables.

The goal of a system of linear equations is to find the values of the variables that satisfy all the equations in the system simultaneously. This can be done by different methods, such as substitution, elimination, or matrix methods.

Systems of linear equations are widely used in mathematics, science, engineering, and economics to model and solve real-world problems involving multiple unknowns. They are a fundamental concept in algebra and linear algebra.

Using this information, we can set up a system of equations to find the cost of a milkshake and the cost of an ice cream sundae. Let's use x to represent the cost of a milkshake and y to represent the cost of an ice cream sundae.

From the first sentence, we can write the equation:

[tex]4x + 2y = 23.5[/tex]

From the second sentence, we can write the equation:

[tex]8x + 6y = 56.5[/tex]

Now we can solve for x and y using any method of solving systems of equations, such as substitution or elimination.

Let's use elimination. Multiplying the first equation by -3 and adding it to the second equation, we get:

[tex]-12x - 6y = -70.5[/tex]

[tex]8x + 6y = 56.5[/tex]

[tex]-4x = -14[/tex]

Dividing both sides by -4, we get:

[tex]x = 3.5[/tex]

Now we can substitute x = 3.5 into one of the original equations to solve for y. Let's use the first equation:

[tex]4x + 2y = 23.5[/tex]

[tex]4(3.5) + 2y = 23.5[/tex]

[tex]14 + 2y = 23.5[/tex]

[tex]2y = 9.5[/tex]

[tex]y = 4.75[/tex]

Answer:

The slope of the given line on the graph is 1/3.

Answer:

1/3

Step-by-step explanation:

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Let's start at 0 with x = 0 and y = 0 or (0,0)

You see the graph crosses coordinate (3,1)

so y goes from 0 to 1 => rise = 1

x goes from 0 to 3 => run = 3

then rise/run = 1/3

The polynomial 8x^(3) + 12x^(2) + 6x + 1 can be factored as (2x + 1)^(3) using Pascal's Triangle and the properties of binomial cubes.

To factor the given polynomial using Pascal's Triangle and the properties of binomial cubes, we need to first identify the coefficients of the polynomial and then use the pattern of Pascal's Triangle to find the factors. Here are the steps:

Step 1: Identify the coefficients of the polynomial. The coefficients are 8, 12, 6, and 1.

Step 2: Use the pattern of Pascal's Triangle to find the factors. The third row of Pascal's Triangle is 1, 3, 3, 1. We can use this pattern to factor the polynomial as follows:

8x^(3) + 12x^(2) + 6x + 1 = (2x + 1)^(3)

Step 3: Use the properties of binomial cubes to simplify the factors. The formula for the cube of a binomial is (a + b)^(3) = a^(3) + 3a^(2)b + 3ab^(2) + b^(3). We can use this formula to simplify the factors as follows:

(2x + 1)^(3) = (2x)^(3) + 3(2x)^(2)(1) + 3(2x)(1)^(2) + (1)^(3) = 8x^(3) + 12x^(2) + 6x + 1

Therefore, the factors of the polynomial are (2x + 1)^(3).

Answer:

Since the hexagon is a 2D shape, it does not have volume. We can find the area of a hexagon but not its volume.

Step-by-step explanation:

The ratio of the areas of two similar figures is equal to the square of the ratio of their corresponding side lengths. In this case, since the figures are hexagons, we can use the ratio of their corresponding side lengths to find the ratio of their areas.

Since the scale factor of the hexagons is 3:7, we know that the ratio of their side lengths is also 3:7. Therefore, the ratio of their areas is:

(3/7)^2 = 9/49

We are given that the area of the smaller hexagon is 18 m^2, so we can use this to find the area of the larger hexagon:

(area of larger hexagon) = (area of smaller hexagon) x (ratio of areas)

(area of larger hexagon) = 18 x (9/49)

(area of larger hexagon) = 3.28 m^2 (rounded to two decimal places)

Since the hexagon is a 2D shape, it does not have volume. We can find the area of a hexagon but not its volume.

The best interpretation of the given information about the value of the company's stocks is that the value of the company's stocks has reached a local minimum at t=5 and is increasing at an increasing rate for 5 ≤ t ≤ 6.

The value of stocks in a certain new startup company is being modeled by the function S(t), where t is in years since the company going public in 2015. The given information about the value of the company's stocks is S′(5)=0 and S′′(t)>0 for 5 ≤ t ≤ 6.

The derivative S′(t) represents the rate of change of the value of the company's stocks with respect to time. Therefore, S′(5)=0 means that the rate of change of the value of the company's stocks at t=5 is zero, or in other words, the value of the company's stocks is not changing at t=5. This indicates that the value of the company's stocks has reached a local maximum or minimum at t=5.

The second derivative S′′(t) represents the rate of change of the first derivative S′(t) with respect to time. Therefore, S′′(t)>0 for 5 ≤ t ≤ 6 means that the rate of change of the first derivative S′(t) is positive for 5 ≤ t ≤ 6, or in other words, the first derivative S′(t) is increasing for 5 ≤ t ≤ 6. This indicates that the value of the company's stocks is increasing at an increasing rate for 5 ≤ t ≤ 6.

The total materials purchase usage variance is -P122.50.

The total materials cost variance is calculated by subtracting the total standard cost from the total actual cost. The total standard cost is P675.00 per batch and there were 14 batches produced during the month, so the total standard cost is P675.00 x 14 = P9,450.00. The total actual cost is calculated by multiplying the quantity purchased by the purchase price for each fruit and then adding them all together. The total actual cost is (300 x P9.50) + (150 x P22.00) + (350 x P7.20) + (80 x P15.40) = P2,850.00 + P3,300.00 + P2,520.00 + P1,232.00 = P9,902.00. The total materials cost variance is P9,902.00 - P9,450.00 = P452.00.

The materials yield variance is calculated by subtracting the standard quantity of materials from the actual quantity of materials used and then multiplying by the standard cost per liter. The standard quantity of materials is 60 liters per batch and there were 14 batches produced during the month, so the standard quantity of materials is 60 x 14 = 840 liters. The actual quantity of materials used is 290 + 130 + 350 + 75 = 845 liters. The materials yield variance is (840 - 845) x P10.00 = -P50.00.

The materials purchase usage variance is calculated by subtracting the standard cost per liter from the actual cost per liter and then multiplying by the actual quantity of materials used. The materials purchase usage variance for each fruit is (P9.50 - P10.00) x 290 + (P22.00 - P21.25) x 130 + (P7.20 - P7.50) x 350 + (P15.40 - P15.00) x 75 = -P145.00 + P97.50 - P105.00 + P30.00 = -P122.50.

Applying the definition of complementary angles, the measures are:

7. m<DBE = 64°; m<CBE = 26°

8. m<WVZ = 84°; m<XVW = 96°

9. m<RTS = 63°; m<PTQ = 27°

10. m<EFG = 139°

m<IFH = 49°

Complementary angles are two angles whose sum is equal to 90 degrees. In other words, when two angles are placed side by side, forming a right angle, they are said to be complementary.

7. Angles DBE and CBE are complementary angles, therefore:

17x + 13 + 32 - 2x = 90

15x + 45 = 90

15x = 90 - 45

15x = 45

x = 3

m<DBE = 17x + 13 = 17(3) + 13 = 64°

m<CBE = 32 - 2x = 32 - 2(3) =  26°

8. 5x + 29 = 9x - 15 [vertical angles are equal]

5x - 9x = -29 - 15

-4x = -44

x = 11

m<WVZ = 9x - 15 = 9(11) - 15 = 84°

m<XVW = 180 - 84 = 96° [linear pair]

9. 8x - 17 = 5x + 13 [vertical angles]

8x - 5x = 17 + 13

3x = 30

x = 10

m<RTS = 5x + 13 = 5(10) + 13 = 63°

m<PTQ = 180 - 90 - 63 = 27°

10. (2x + 3) + (6x + 25) = 180 [linear pair]

8x + 28 = 180

8x = 180 - 28

8x = 152

x = 19

m<EFG = 6x + 25 = 6(19) + 25 = 139°

m<IFH = 90 - (2x + 3) = 90 - (2(19) + 3)

m<IFH = 49°

Daniel bought 8 apples and 16 oranges. The equation we will use to solve the problem is 0.35x + 0.5(2x) = 5.4.

We know that Daniel bought twice as many oranges as apples, so let's call the number of apples he bought "x". Therefore, the number of oranges he bought would be "2x".

We also know that each apple cost $0.35 and each orange cost $0.50, so we can write the equation:

0.35x + 0.5(2x) = 5.4

Simplifying the equation, we get:

0.35x + x = 5.4 ÷ 0.5

0.35x + x = 10.8

1.35x = 10.8

x = 8

So, Daniel bought 8 apples, which means he also bought 2x = 16 oranges.

However, we need to check if this solution makes sense hence the cost of the apples would be:

0.35 × 8 = 2.8

And the cost of the oranges would be:

0.5 × 16 = 8

Adding those together, we get:

2.8 + 8 = 10.8

The final amount for the investment of $5,000 is $ 6,749.29.

Compound interest is a type of interest calculation in which the interest earned on an initial principal amount is added to the principal, and the new total amount earns interest in subsequent periods.

This means that the interest earned in each period is based on the total amount, which includes both the principal and the accumulated interest from previous periods.

The formula used for compound interest:  

Where:

P = Initial investment

r = Rate of interest (as a decimal)

n = Number of compounds

t = Time period in years

Here we have

P = $5,000,

r = 6% = 0.06,

n = 4 (since the interest is compounded quarterly), and

t = 5 years.  

Using the above formula

[tex]A = 5000(1 + 0.06/4)^{(4*5)[/tex]

[tex]A = 5000(1.015)^{20[/tex]

[tex]A = 5000(1.34985711)[/tex]

[tex]A =\$6,749.29[/tex]

Therefore,

The final amount for the investment of $5,000 is $ 6,749.29.

Answer: Explanation below

Step-by-step explanation:

R4000 is the money to be split

5:3:2 is the ratio

We can add the ratios together.

5+3+2=10

The first winner = 5/10 x 4000

                           = R2000

The second winner = 3/10 x 4000

                                 = R1200

The third winner = 2/10 x 4000

                             = R800

Hope this helped :)
