What is the value of n? Enter your answer in the box. n = cm Circle with two intersecting chords forming an x shape in the circle. The top left side of the x shape is labeled 7 centimeters. The top right side of the x shape is labeled 4 centimeters. The bottom left side of the x is labeled n. The bottom right side of the x is labeled 8 centimeters.

Answers

Answer: The length of the bottom left side is 14.

To find the length of this side, we need to know the relationship between the different sections when chords cross each other.

The relationship is that if you multiply the 2 parts of each chord together, it will equal the product of the two sides in the other chord.

Our equation can be written as:

7(8) = 4(x)
56 = 4x
14 = x

The value of n for the given circle with chords is; n = 14

How to find the length of a chord?

To find the length of the given side with length "n", we must know the relationship between the different sections when the chords cross one another.

Now, the relationship we require is that when we multiply the 2 parts of both chords together, it will be equal to the product of the two sides in the other chord. Thus;

7(8) = 4(n)

56 = 4n

14 = n

Solving Systems of Equations by Elimination

3) 7x + 3y= 22 4y= 20

4) -2x + y= 10 4x - y= -14

Answers

Answer:

3) [tex]x=1\\ y=5[/tex]

4) [tex]x=-2\\ y=6[/tex]

Step-by-step explanation:

3) For this system of equation you already has one variable in the second equation. Therefore, you only need to solve for [tex]y[/tex] in the second one and substitute its value into the first equation to calculate [tex]x[/tex]:

[tex]\left \{ {{7x + 3y= 22} \atop {4y=20}} \right. \\[/tex]

[tex]y=\frac{20}{4} \\ y=5[/tex]

[tex]7x + 3(5)= 22\\ 7x=7\\x=1[/tex]

4) You must add both equations to cancel the variable [tex]y[/tex] and solve for [tex]x[/tex]. Then, susbstiute the value of this variable into one of the original equations to calculate [tex]y[/tex]:

[tex]\left \{ {{-2x+y=10} \atop {4x-y=-14}} \right.[/tex]

Determine if the properties define a Ray or a line segment

Answers

a Ray has one endpoint and continues forever in One Direction.

a line segment has 2 endpoints and a defined measure
Final answer:

A ray in geometric optics represents the path of light as a straight line originating from a point, while a line segment is a part of a line with two endpoints and a measurable length. The properties mentioned can be used to determine if they define a ray or a line segment.

Explanation:

A ray in geometric optics is a straight line that originates at some point. In the context of light, a ray represents the path of light as it travels. When light encounters objects or changes media, it may change direction but it continues to travel in a straight line or as a ray. We can think of a ray of light as a straight line or a laser ray.

A line segment, on the other hand, is a part of a line with two endpoints. It has a definite length and can be measured. In the context of light, a line segment would indicate a finite path of light.

Given the properties mentioned, we can determine if they define a ray or a line segment. If the properties describe a straight line with no defined endpoints, it is a ray. If the properties suggest a line with two endpoints and a measurable length, it is a line segment.

A surveyor standing 63 meters from the base of a building measures the angle to the top of the building and finds it to be 38°. the surveyor then measures the angle to the top of the radio tower on the building and finds that it is 48°. how tall is the radio tower?

Answers

The height of the radio tower is 20.77 meters.

If you draw a picture of the problem, you will see that you have to solve two right triangle problems with the tangent ratio.

If we subtract the measurements of the two triangles, we will have only the length of the radio tower.

tan(48) = x / 63
x = 69.97

tan(38) = x / 63
x = 49.22

69.97 - 49.22 = 20.77 for the height of the radio tower

Sampling is the choosing of a group of individuals from within a statistical population to estimate attributes of the entire population. Options C & D are right.

What is the sampling method ?

Sampling is the choosing of a group of individuals from within a statistical population to estimate attributes of the entire population in statistics, quality assurance, and survey methods.

The following options are right;

C. The manager selects 20 boards at random each day for 5 days and examines them.

Reason;

This method, which involves sampling 30 boards in a row an hour after manufacturing begins, does not yield a significant sample size.

Furthermore, if a component of the equipment fails later in the day, the statistics will be deceptive. Similarly, statistics will be deceptive if the gear is only defective until it "warms up."

D. The manager sends an email to 20 customers who buy lumber from the mill, asking each how many of the boards they bought the past week was defective. Results from the first 5 customers to respond are tallied.

Reason;

These  technique, a voluntary survey, is likely to elicit replies solely from those who have strong feelings about their product.

Hence Options C & D are right.

To learn more about the sampling method refer to the link;

https://brainly.com/question/15125943

Methods B and D are biased for determining defective boards, while methods A and C minimize bias. Random sampling across different times and responses reduces bias in data.

The goal is to determine which sampling methods are likely to be biased when finding the percentage of defective boards produced by a sawmill.

A. Every 40th board produced over the course of 1 week is selected and examined. Bias: This method minimizes bias as it spreads out samples over time.B. On 1 day, an hour after the sawmill begins production, 30 boards in a row are selected and examined. Bias: This is likely biased as it does not account for variations in production quality at different times of the day.C. The manager selects 20 boards at random each day for 5 days and examines them. Unbiased: This method reduces bias by randomly sampling boards each day.D. The manager sends an email to 20 customers who buy lumber from the mill, asking each how many of the boards they bought the past week were defective. Results from the first 5 customers to respond are tallied. Bias: This method is extremely biased as it relies on customer responses, which can be non-representative and influenced by response rate.

In summary, method B and method D are likely to introduce bias in sampling. Methods A and C are designed to minimize bias and provide a more accurate representation of defective boards.

A jar lid has a diameter of 42 millimeters. What is the circumference of the lid? Use 22/7 for π.

A. 924 mm
B. 114 mm
C. 66 mm
D. 132 mm

Answers

The formula for the circumference is pi times the diameter.

The circumference is 42 x 3.14.

42 x 3.14 = 131.88mm

The answer would be D.

Hope this helps!

- Juju

Final answer:

The circumference of the lid is approximately 132 millimeters, Thus, option D is correct.

Explanation:

To find the circumference [tex](\( C \))[/tex] of the lid, we use the formula for the circumference of a circle:

[tex]\[ C = \pi \times d \][/tex]

Where [tex]\( d \)[/tex] is the diameter of the circle.

Given that the diameter (\( d \)) of the lid is 42 millimeters and using the value of [tex]\( \pi \)[/tex] as [tex]\( \frac{22}{7} \)[/tex], we can calculate the circumference as follows:

[tex]\[ C = \frac{22}{7} \times 42 \][/tex]

[tex]\[ C = \frac{22 \times 42}{7} \][/tex]

[tex]\[ C = \frac{924}{7} \][/tex]

[tex]\[ C \approx 132 \, \text{mm} \][/tex]

Therefore, the circumference of the lid is approximately 132 millimeters, which corresponds to option D.

The graph shows the function of f(x)=(3.5)^x

Which graph represents the function g(x)=(3.5)^x-1?

Answers

The one that passes through the origin. That one in the lower left part.

Answer:

The graph of the function is the last graph.

Step-by-step explanation:

To know which graph represents the function [tex]g(x)=3.5^{x-1}[/tex] you should give values to x and compare it with the values on the graphs, as follows:

When x=-3

[tex]g(-3)=3.5^{-3-1}[/tex]

[tex]g(-3)=3.5^{-4}[/tex]

[tex]g(-3)=0.007[/tex]

So, the first point is (-3, 0.007)

When x=-2

[tex]g(-2)=3.5^{-2-1}[/tex]

[tex]g(-2)=3.5^{-3}[/tex]

[tex]g(-2)=0.02[/tex]

So, the second point is (-2, 0.02)

When x=-1

[tex]g(-1)=3.5^{-1-1}[/tex]

[tex]g(-1)=3.5^{-2}[/tex]

[tex]g(-1)=0.08[/tex]

So, the third point is (-1, 0.08)

When x=0

[tex]g(0)=3.5^{0-1}[/tex]

[tex]g(0)=3.5^{-1}[/tex]

[tex]g(0)=0.29[/tex]

So, the fourth point is (0, 0.29)

When x=1

[tex]g(1)=3.5^{1-1}[/tex]

[tex]g(1)=3.5^{0}[/tex]

[tex]g(1)=1[/tex]

So, the fifth point is (1, 1)

When x=2

[tex]g(2)=3.5^{2-1}[/tex]

[tex]g(2)=3.5^{1}[/tex]

[tex]g(2)=3.5[/tex]

So, the fourth point is (2, 3.5)

If you compares all the points, the graph of the function is the last graph.

Round the answer to the nearest penny.

Enter your answer in the box.

Answers

The mean for the second week increased by $0.40.

The mean for the first week is found by adding the data points and dividing by 5:
(12.99+10.50+9.89+6.90+7.58)/5 = $9.57

Since the cost increased by $2 the second week, we add two to the data points before dividing by 5:
(12.99+10.50+9.89+6.90+7.58+2)/5 = $9.97

To find the increase in means, subtract them:
