Find the perimeter of the quadrilateral. Simplify your answer

The total length of the beads on one braid is 8.11 centimeters

Keyana places 7 beads on one braid, and each bead is 1.03 centimeters long. So, the total length of these 7 beads would be 7 multiplied by 1.03, which is equal to 7.21 centimeters.

To find the total length of the beads on one braid, we need to evaluate the expression:

7 x 1.03 + 0.9

Multiplying 7 by 1.03 gives us:

7 x 1.03 = 7.21

Then, adding 0.9 gives us:

7.21 + 0.9 = 8.11

Therefore, the total length of the beads on one braid is 8.11 centimeters.

So, the correct answer is B.8.11 centimeters.

The two tangent theorem can be used to find the required equations and  the lengths of the of the segments and tangents as follows;

4. 6x - 16 = 4x - 10

5. x = 13

6. 10y - 3 = 7y + 21

7. y = 8

8. GK = 139
9. GZ = 77

10. ZL = 62

The two tangent theorem states that intersecting tangent segments from the point of the intersection to the circle are congruent.

The two tangent theorem indicates;

PZ = GZ, and ZK = ZL

Therefore;

4. An equation that can be used to solve for x can be obtained from the equation formed using the two tangent theorem and plugging in the value of ZK and ZL in the equation; ZK = ZL

The equation is therefore; 6·x - 16 = 4·x + 10

5. 6·x - 16 = 4·x + 10

6·x - 4·x = 10 + 16 = 26

2·x = 26

x = 13

6. The equation that can be used to solve for y can be obtained from the equation PZ = GZ, by plugging in the values of PZ and GZ in the equation as follows;

10·y - 3 = 7·y + 21

7. 10·y - 3 = 7·y + 21

10·y - 7·y = 21 + 3 = 24

3·y = 24

y = 24/3 = 8

y = 8

8. GK = GZ + ZK

Therefore; GK = 7·y + 21 + 6·x - 16

GK = 7 × 8 + 21 + 6 × 13 - 16 = 139

GK = 139

9. GZ = 7·y + 21 = 7 × 8 + 21 = 77

GZ = 77

10. ZL = 4·x + 10

Therefore; ZL = 4 × 13 + 10 = 62

ZL = 62

The range of 49 is the most appropriate measure of variability to use to represent the spread of donations received by the charity in this data set.

what is statistics?

Statistics is a branch of mathematics that deals with collecting, analyzing, interpreting, presenting, and organizing data. It involves the study of methods for designing experiments and surveys, analyzing and interpreting data, and making decisions based on data. Statistics plays an important role in a wide range of fields, including science, social science, economics, finance, engineering, and many others. It is used to draw conclusions, make predictions, and inform decision-making by providing a quantitative and objective approach to understanding and analyzing data.

The most accurate measure of variability to use for this data set is the range of 49. The range is the difference between the highest and lowest values in the data set, which in this case is 59 - 10 = 49. The range provides a simple and straightforward measure of the spread of the data and is useful when the data is not too skewed.

While the data in this set is skewed, the range is still an appropriate measure of variability because there are no extreme outliers that would significantly affect the range. The IQR (interquartile range) is another measure of variability that is useful for skewed data, but in this case, it would not be the most appropriate choice because the data set is not divided into quartiles and the IQR would not provide additional information beyond what the range already shows.

Therefore, the range of 49 is the most appropriate measure of variability to use to represent the spread of donations received by the charity in this data set.

Rounding to the nearest hundredth, we get an expected count of 128.06 for that cell.

One of the four fundamental mathematical processes, along with addition, subtraction, multiplication, and division, is addition.

To find the expected count for the cell corresponding to navigation from social media before Mabel made the change, we need to calculate the total number of observations in that category (before the change), and the total number of observations in the entire sample (before and after the change). Then we can use those values to calculate the expected count.

Total number of observations in the social media category before the change:

57 + 71 = 128

Total number of observations in the entire sample before the change:

170

Expected count for the cell corresponding to navigation from social media before the change:

(expected proportion of social media visitors) x (total number of observations in the entire sample before the change)

We can estimate the expected proportion of social media visitors by calculating the overall proportion of social media visitors in the entire sample before the change:

128 / 170 = 0.7529

So the expected count for the cell corresponding to navigation from social media before the change is approximately:

0.7529 x 170 = 128.06

Rounding to the nearest hundredth, we get an expected count of 128.06 for that cell.

The box in feet with a length of 14" x 10' x 12" then volume of the box is 140.4 cubic feet.

What is unit rate?

A unit rate is a ratio in which the denominator is 1. It is a rate that compares a quantity to one unit of another quantity.

To calculate the volume of a box in feet, we need to convert all measurements to the same unit of measurement. Let's convert 14 inches to feet:

1 foot = 12 inches

14 inches = 14/12 feet

14 inches = 1.17 feet (approx.)

So the measurements of the box in feet are:

Length = 1.17 feet

Width = 10 feet

Height = 12 feet

To calculate the volume of the box, we need to multiply the length, width, and height:

Volume = Length x Width x Height

Volume = 1.17 feet x 10 feet x 12 feet

Volume = 140.4 cubic feet

Therefore, the volume of the box is 140.4 cubic feet.

To calculate the overall surface range of all 64 littler 3d shapes, we have to be discover the surface region of each 3d shape and after that include them up.

Each 3d shape has 6 faces, so ready to utilize the equation for the range of a square to discover the zone of one confront, and after that duplicate by 6:

Surface range of one little 3d shape = [tex]6 x (side length of little cube)^2[/tex]

To discover the side length of the littler 3d shapes, we ought to separate the side length of the beginning 3d shape by the number of littler 3d shapes in each measurement.

Since there are 4 littler 3d shapes in each measurement (4 x 4 x 4 = 64), we have:

Side length of little 3d shape = (side length of beginning 3d shape) / 4

= 4.5 cm / 4

The center-radius form of the circle is:

(x + 3)² + (y - 5)² = 25

What is a circle?

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Given the equation (x - 11)² + (y + 4)² = 15, we can see that the equation is in standard form:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle, and r is the radius. Comparing the given equation with the standard form, we can see that:

h = 11, k = -4, and r² = 15

Taking the square root on both sides, we get:

r = √15

Therefore, the center of the circle is (11, -4) and the radius is √15.

The center-radius form of the circle with center (-3, 5) that passes through the point (0, 1) can be found using the formula:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and r is the radius. We are given that the center of the circle is (-3, 5), so we can substitute these values into the formula:

(x - (-3))² + (y - 5)² = r²

Simplifying the expression on the left-hand side, we get:

(x + 3)² + (y - 5)² = r²

Now, we need to find the value of r. Since the circle passes through the point (0, 1), we can substitute these values into the equation above:

(0 + 3)² + (1 - 5)² = r²

Simplifying the expression on the left-hand side, we get:

9 + 16 = r²

25 = r²

Taking the square root on both sides, we get:

r = 5

Therefore, the center-radius form of the circle is:

(x + 3)² + (y - 5)² = 25

The probability of getting a flush when selecting 5 cards from a standard 52-card deck is about 0.198%.

Hi! To calculate the probability of getting a flush (all 5 cards from the same suit) when selecting 5 cards from a standard 52-card deck, follow these steps:

1. Calculate the total number of ways to choose 5 cards from a 52-card deck. This can be computed using combinations: C(52, 5) = 52! / (5! * (52-5)!), where ! denotes a factorial. C(52, 5) = 2,598,960.

2. Calculate the total number of ways to get a flush. There are 4 suits in a deck, and you need all 5 cards to be from the same suit. For each suit, you can choose 5 cards from the 13 available in that suit: C(13, 5) = 1,287. Since there are 4 suits, the total number of flushes is 4 * C(13, 5) = 4 * 1,287 = 5,148.

3. Compute the probability of getting a flush by dividing the total number of flushes by the total number of ways to choose 5 cards: probability = 5,148 / 2,598,960 = 0.00198, or approximately 0.198%.

If the measure of angle RST is 60°, and RS=4 units, then the area of sector RST is 8.374 square units.

In geometry, a "Sector" of a circle is defined as the portion of circle enclosed by two radii and the arc between them. It can be thought of as a slice or a wedge cut out of a circle.

To find the area of the "sector-RST" in circle centered at "S", we use the formula for area of a sector of a circle, which is :

⇒ Area of sector = (θ/360) × π × r²,

where θ = central angle of sector in degrees, π = 3.14159, and r = radius of circle,

In this case, we are given that m∠RST = 60 degrees and RS = 4 units. Since RS is the radius of the circle centered at "S", we use RS = r,

Substituting the values, θ = 60 degrees, r = RS = 4 units,

We get,

⇒ Area of sector RST = (60/360) × 3.14 × (4)²,

= (1/6) × 3.14 × 16,

= 8.374 square units,
