Identify where T goes if X is the midpoint of BT

Answer:  a.) Circle B  

               b.) 9.42

Step-by-step explanation:

A diameter of 9 cm means that the circumference of Circle A is approximately 28.26 cm.

Circumference = Diameter x π

9 x 3.14 = 28.26

A radius of 6 cm means the circumference of Circle B is approximately 37.68 cm.

Circumference = 2 x Radius x π

2 x 6 x 3.14 = 37.68  

37.68 > 28.26

37.68 - 28.26

The approximate 95% confidence interval for the sample's mean number of ounces of ketchup per bottle is 24 ± 0.029

Based on the margin of error, the confidence interval is created. The size of the confidence interval for a specific confidence level is determined by three variables. These are population size, sample size, and percentage.

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.

Therefore,

The sample's average bottle contains 24 ounces of ketchup, with a 96% confidence interval of 0.029.

Detailed explanation:

Given

The average is 24 ounces.

0.2 ounces is the standard deviation.

Sample Size, n = 49 ketchup bottles

95% confidence interval (0.95)

The actions that must be taken in order to compute the confidence at this level are as follows:

1. Determining the degree of freedom

You may compute the degree of freedom (d f) by taking 1 out of the sample size.

d f = n - 1

d f = 49 - 1

d f = 48

2. Divide by two after subtracting the confidence level from 1.

α = (1 – .95) / 2 = 0.025

3. Consult the t-distribution table to get the solutions to (1) and (2).

When = 0.025 and there are 48 degrees of freedom (df),

We get 2.0106

4. Separate

=0.2/√49

=0.2/7

=0.028

=0.029

5. The following example is used to compute the 95% confidence interval.

As a result of step 5, X.

in which x = 24

Thus, we have

Center of a data set is a single number that sumarizes the entire data, the median is the best measure of center to use in this distribution.

Median is the midpoint value of a data set, where the values are arranged in ascending or descending order:

As a first step let's organize the data in ascending order:

3, 4, 5, 6, 7, 8, 9, 10, 11

The median is 7.

Answer:

x = -1/4, or -0.25

Step-by-step explanation:

1/3 + 2/3x = -5/6x - 1/24

first lets write everything in the common denominator of 24

8/24 + 16/24x = -20/24x - 1/24

now we take all our x's onto 1 side, and all our numbers onto the other side

36/24x = -9/24

lets cancel out all the 24's

36x = -9

x = -9/36

now lets simplify

x = -1/4, or -0.25

Step-by-step explanation:

Solution and answer

Let x be the number that can be multiplied by 3/4 and get 1.

(3/4)*x = 1                     Multiiply both sides by 4

4*(3/4)x = 4*1                Combine

3x = 4                            Now divide by 3

3x/3 = 4/3                    

x = 1 1/3     or x = 4/3  or x = 1.3333333

Answer:

[tex]a_{n}[/tex] = 4 - 3(n - 1) and a₈ = - 17

Step-by-step explanation:

a recursive formula is of the form

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + d ( d is the common difference )

compare to

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 3

then d = - 3

the explicit formula for an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term

here a₁ = 4 and d = - 3 , then

[tex]a_{n}[/tex] = 4 - 3(n - 1) ← explicit formula

then

a₈ = 4 - 3(8 - 1) = 4 - 3(7) = 4 - 21 = - 17

The length of Plan A is 1 hour. The duration of Plan B is 1/3 hours

The first step is to formulate a set of linear equations :

2a + 3b = 3 equation 1

5a + 6b = 7 equation 2

Where:

In order to determine the value of a, take the following steps:

Multiply equation 1 by 2:

4a + 6b = 6  equation 3

Subtract equation 3 from equation 2

a = 1

In order to determine the value of b, substitute for the value of a in equation 3:

4(1) + 6b = 6

4 + 6b = 6

6b = 6 - 4

6b = 2

b = 2/6

b = 1/3 hours

Answer:

187 people

Step-by-step explanation:

5 to 6 is the same as 5/6. 5 is the men and 6 is the women. We know that there are 102 women so we can arrange this equation.

[tex]\frac{5}{6}[/tex]  = [tex]\frac{x}{102}[/tex]

Re-arrange the equation to find x, or the number of men in the company.

[tex]\frac{(102*5)}{6}[/tex] = x

x = 82

We have found the number of men in the company. Now add the number of men and women.

102 + 82 = 187

187 total people!

Answer: 187 employees

Step-by-step explanation:

ratio of men to women: 5:6

number women working for company: 102

to work out the number of men working for the company, you must first find out what you have to multiply 6 by to get to 102

therefore you do 102/6 which is 17

now you do 17x5 to work out how many men are working for the company which is 85

total number of employees: 102+85=187

The inequality for the possible value of the number of tacos sold in the number of burrito will be;

⇒ $3.75x + $7.75y < 430

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Cost of each taco = $3.75

Cost of each burrito = $7.75

And, Hannah Montana less than 430 of worth of tacos and burritos each day.

Now,

Let the number of taco = x

Let the number of burrito = y

So, Cost of taco = $3.75x

Cost of burrito = $7.75y

Since, Hannah Montana less than 430 of worth of tacos and burritos each day.

So, we can formulate the inequality as;

⇒ $3.75x + $7.75y < 430

Therefore,

The inequality for the possible value of the number of tacos sold in the number of burrito will be;

⇒ $3.75x + $7.75y < 430

The area per person allowed for Festival B is 19 m² greater than the area per person allowed for Festival A.

To compute the area per person for each festival, we determine the total areas for Festival A and Festival B.

The total area for each festival is then divided by the most significant number of persons allowed.

Remember that the area is the product of length and width squared.

The area of the rectangular field for Festival A = 80,000 m²

The length of the field for Festival B = 2,000 m

The width of the field for Festival B = 700 m

The area of the rectangular field for Festival B = 1,400,000 m² (700 x 2,000)

The most significant number of persons attending Festival A = 425

The greatest number of persons attending Festival B = 6,750

The area per person for Festival A = 188 m² (80,000 m²/425)

The area per person for Festival B = 207 m² (1,400,000 m²/6,750)

The difference between the area per person for Festival A and Festival B = 19 m² (207 - 188).

Thus, we can conclude that Festival B has 19 m² areas per person allowed than Festival A.

To find the reflection.

Now, According to the question:

Let's know the Reflection over x - axis:

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Come to the solution:

Dilation: (x, y) -> (3/4 * x, 3/4 * y)

F' (3/4 × -2 , 3/4 × 2) = (-3/2 , 3/2)

G'  (3/4 × -2 , 3/4 × -4) = (-3/2 , -3)
